When used in this Annual Report on Form 10-K, unless otherwise stated or the context otherwise requires, the terms "Cleveland BioLabs," the "Company," "CBLI," "we," "us," and "our" refer to Cleveland BioLabs, Inc. and its consolidated subsidiaries, BioLab 612, LLC and Panacela Labs, Inc.

GENERAL OVERVIEW

Cleveland BioLabs is an innovative biopharmaceutical company developing novel approaches to activate the immune system and address serious medical needs. Our proprietary platform of Toll-like immune receptor activators has applications in mitigation of radiation injury and immuno-oncology. We combine our proven scientific expertise and our depth of knowledge about our products’ mechanisms of action into a passion for developing drugs to save lives.

Entolimod, a Toll-like receptor 5 ("TLR5") agonist, which we are developing as a medical radiation countermeasure ("MRC") for reducing the risk of death following exposure to potentially lethal irradiation Acute Radiation Syndrome ("ARS") is our most advanced product candidate. Other indications, including immunotherapy for oncology, have been or are being investigated as well.

Entolimod as a MRC is being developed under the United States Food & Drug Administration’s ("FDA’s" or "Agency's") Animal Efficacy Rule (the "Animal Rule") for the indication of reducing the risk of death following exposure to potentially lethal irradiation occurring as a result of a radiation disaster (see "- Government Regulation - Animal Rule"). We believe that entolimod is the most efficacious MRC currently in development. The following is a summary of the clinical development of entolimod as an MRC to date and its related regulatory status.

We have completed two Good Clinical Practices ("GCP") clinical studies designed to evaluate the safety, pharmacokinetics and pharmacodynamics of entolimod in a total of 150 healthy subjects. We have completed a Good Laboratory Practices ("GLP"), randomized, blinded, placebo-controlled, pivotal study designed to evaluate the dose-dependent effect of entolimod on survival and biomarker induction in 179 non-human primates exposed to 7.2 Gy total body irradiation when entolimod or a placebo was administered at 25 hours after radiation exposure. We have also completed a GLP, randomized, open-label, placebo-controlled, pivotal study designed to evaluate the dose-dependent effect of entolimod on biomarker induction in 160 non-irradiated non-human primates.

In 2015, following confirmation from the FDA on the sufficiency of our existing efficacy and safety data and animal-to-human dose conversion, we submitted to the FDA an application for pre-Emergency Use Authorization ("pre-EUA"), a form of authorization granted by the FDA under certain circumstances (see "- Government Regulation - Emergency Use Authorization"). As part of the Company's response to pre-EUA review, comments received from the FDA, we met with the Agency in the first quarter of 2016 to discuss various aspects of entolimod manufacturing. The Agency specified that the Company needed to establish comparability between the drug formulation used in previously conducted preclinical and clinical studies and the entolimod drug formulation proposed for commercialization under the pre-EUA. The FDA also indicated that further review of the pre-EUA dossier would not proceed until these comparability data have been evaluated by the Agency.

To establish the comparability of the older formulation and the new formulation, the FDA requested that we first perform a side-by-side analytical comparability study between the two entolimod drug formulations. Thereafter, the Agency requested that we conduct an in vivo study in non-human primates ("NHP") to establish bio-comparability. The side-by-side analytical comparability analysis of the two formulations of entolimod was completed and the study report was submitted to the FDA in the first quarter of 2017. The FDA has reviewed this data and indicated that we could proceed with the bio-comparability study in NHP in the second quarter of 2017. Due to unexpected delays in the analytical tests performed by Company vendors, the study was finally completed and data were unblinded in early 2019. While the NHP study was ongoing, the FDA proceeded with further review of the entolimod chemistry, manufacturing, and controls ("CMC") information in our pre-EUA dossier and in first quarter 2019 the Agency provided us with comments and questions on various aspects of entolimod CMC. Per FDA recommendation, the Company has now requested a meeting to brief the FDA on the results of the NHP bio-comparability data and is preparing responses to the FDA comments on entolimod CMC. We expect that after review and discussion of the bio-comparability data and the CMC information, the FDA will proceed with review of additional components of the pre-EUA dossier.

In March 2019, at the FDA's suggestion, with positive NHP bio-comparability data in hand, CBLI requested a meeting with the FDA to discuss the re-initiation of pre-EUA review including specifically review of the animal-to-human dose conversion included in the pre-EUA application. Following review of the background information provided for the meeting, the FDA responded that while the NHP biocomparability data were acceptable, the analytical comparability data that they had accepted in 2017 were no longer acceptable and therefore, the review of the pre-EUA application remained on hold. In August 2019, CBLI requested a Special Protocol Assessment to confirm the End-of-Phase 2 agreements on design of the remaining pivotal NHP efficacy study to support submission of an eventual Biologics License Application ("BLA"). Following review of the NHP efficacy study protocol, the FDA responded that the previously agreed study design was no longer acceptable. Based on these two documented points of disagreement (one related to the pre-EUA application and one related to a future BLA), CBLI requested a Formal Dispute Resolution ("FDR") with the FDA. The outcomes of the FDR included, among other things, an agreement that CBLI had documented both analytical comparability and biocomparability in the NHP. As a result, the review of the animal-to-human dose conversion has recommenced. CBLI has redesigned the remaining pivotal NHP efficacy study to support a future BLA and submitted the protocol synopsis for review with the FDA, agreeing to an accelerated review time-frame. In November 2019, CBLI also submitted a clinical protocol to support the acquisition of the final human safety data and to further support eventual approval of an entolimod BLA. The FDA has placed the protocol on clinical hold with recommendations for design revisions that will allow lifting of the hold following review of the revised protocol.

If the FDA authorizes the pre-EUA application, then Federal agencies will be free to procure entolimod for stockpiling so that the drug is available to distribute in the event of an emergency, i.e., prior to the drug being formally approved by FDA under a BLA. Such authorization is not equivalent to full licensure through approval of a BLA, but precedes full licensure, and, importantly, would position entolimod for potential sales in advance of full licensure in the U.S. We further believe pre-EUA status will position us to explore sales opportunities with foreign governments.

In addition, the Company submitted a Marketing Authorization Application ("MAA") with the European Medicines Agency ("EMA") for entolimod as a MRC in Europe. The MAA was validated by the EMA in the fourth quarter of 2017 but was withdrawn in August 2018 because a complete response to certain questions posed by the EMA could not be prepared in the time frame required by the EMA's review process as a result of the delay in our receipt of the results of the bio-comparability study. The MAA application remains in a withdrawn state and we continue to evaluate our next steps with the EMA in parallel with progress on review of the pre-EUA application.

In September 2015, we announced two awards totaling approximately $15.8 million in funding from the United States Department of Defense ("DoD"), office of Congressionally Directed Medical Research Programs to support further development of entolimod as a MRC. These awards funded additional preclinical and clinical studies of entolimod, which are needed for a BLA. In October 2016, the DoD modified the original statement of work of one of these contracts (Joint Warfighter Medical Research Program ("JWMRP") contract award number W81XWH-15-C-0101) by eliminating certain tasks no longer deemed critical for the preparation of the BLA and established new tasks to address the formulation questions raised by the FDA during the review of the pre-EUA dossier, including an aim to conduct the NHP bio-comparability study along with other drug manufacturing -related activities. In September 2017, the DoD further modified the contract by extending its term to 2019 on a no-cost basis. In February 2019, the DoD further modified the contract by extending its term to April 2020 on a no-cost basis. In March 2020, the DoD further modified the contract by extending its term to September 2020 on a no-cost basis. Both contracts providing for these awards from the DoD have concluded.

In addition to development work on the MRC for reducing the risk of death from ARS indication, we have completed a Phase 1 open-label, dose-escalation trial of entolimod in 26 patients with advanced cancer in the U.S. The data for the U.S. study were presented at the 2015 annual meeting of the American Society of Clinical Oncology ("ASCO"). Seven (7) additional patients have been dosed with the entolimod drug formulation proposed for commercialization under the pre-EUA and MAA in an extension of this study performed in the Russian Federation ("Russia").

In the third quarter of 2018, the Company created a joint venture called Genome Protection, Inc. ("GPI") with Everon Biosciences, Inc. ("Everon"). GPI, which is currently 50% owned by the Company and 50% owned by Everon, is undertaking a research and development program aimed at clinical testing of entolimod and GP532 (a variant of our entolimod drug candidate) and the development of medications with anti-aging and other indications associated with genome damage. GPI is being initially funded by an investment from venture capital fund Norma Investments Limited ("Norma"). Under the terms of the arrangement with Norma, GPI granted Norma the right to purchase shares of GPI’s capital stock in the future in exchange for the payment of up to $30 million, of which $10.5 million was paid shortly after execution of the transaction documents.

Mobilan is a recombinant non-replicating adenovirus that directs expression of TLR5 and its agonistic ligand, a secretory non-glycosylated version of entolimod we are also developing through our subsidiary, Panacela Labs, Inc. ("Panacela"). Two randomized, placebo-controlled, dose-ranging studies of Mobilan in men with prostate cancer are currently ongoing in the Russian Federation.

Merger with Cytocom, Inc.

As previously disclosed, on October 16, 2020, the Company, High Street Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of the Company ("Merger Sub"), and Cytocom, Inc., a Delaware corporation ("Cytocom"), entered into an Agreement and Plan of Merger (the "Merger Agreement"), pursuant to which, among other matters, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Merger Sub will merge with and into Cytocom, with Cytocom continuing as a wholly owned subsidiary of the Company and the surviving corporation of the merger (the "Merger"). Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger, each outstanding share of Cytocom common stock, each outstanding share of Cytocom preferred stock that was not, by its terms, converted into shares of Cytocom common stock immediately prior to the effective time of the merger, and each vested restricted stock unit of Cytocom will be converted into the right to receive a number of shares of the Company’s common stock determined by the application of an exchange formula set forth in the Merger Agreement. The exchange formula provides that the total number of shares of the Company’s common stock to be issued as merger consideration for the Cytocom’s capital stock will, upon issuance, be equal to approximately 61% of the outstanding shares of the combined company’s common stock. Accordingly, under the exchange ratio formula in the Merger Agreement, as of immediately after the Merger, the former Cytocom stockholders are expected to own approximately 61% of the outstanding shares of the combined company’s common stock on a fully diluted basis and stockholders of the Company as of immediately prior to the Merger are expected to own approximately 39% of the outstanding shares of the combined company’s common stock on a fully diluted basis. Certain adjustments to this ratio will be made in respect of each party’s net cash at the time of the closing of the Merger, as determined in accordance with the Merger Agreement. Each unvested Cytocom restricted stock unit award will be converted into a restricted stock unit award of the Company. Immediately following the effective time of the Merger, the board of directors of the Company will consist of seven members, three of whom will be designated by the Company and four of whom will be designated by Cytocom. In addition, upon the closing of the Merger, Cytocom’s Chief Executive Officer, Michael Handley, will serve as Chief Executive Officer of the combined company. The closing of the Merger is subject to the satisfaction or waiver of certain conditions including, among other things, (i) the required approvals by the Company’s stockholders, (ii) the accuracy of the respective representations and warranties of each party, subject to certain materiality qualifications, (iii) compliance by the parties with their respective covenants, (iv) the absence of any law or order preventing the Merger and related transactions, (v) the shares of the Company’s common stock to be issued in the Merger being approved for listing (subject to official notice of issuance) on Nasdaq as of the closing and (vi) a registration statement on Form S-4 having become effective in accordance with the provisions of the Securities Act of 1933, as amended, and not being subject to any stop order or proceeding (or threatened proceeding by the SEC) seeking a stop order with respect to such registration statement that has not been withdrawn.

CORPORATE INFORMATION

We were incorporated in Delaware in June 2003 as a corporation spun off from The Cleveland Clinic. We exclusively license our founding intellectual property from The Cleveland Clinic. In 2007, we relocated our operations to Buffalo, New York and became affiliated with Roswell Park Cancer Institute ("RPCI"), through technology licensing and research collaboration relationships. Our common stock is listed on the NASDAQ Capital Market under the symbol "CBLI."

Our principal executive offices are located at 73 High Street, Buffalo, New York 14203, and our telephone number at that address is (716) 849-6810.

Since inception we have formed several subsidiaries to best capitalize on our ability to leverage financial and clinical development resources in Russia. In December 2009, we created Incuron LLC ("Incuron") with BioProcess Capital Ventures ("BCV") to develop Curaxin compounds (defined below). We have since sold our equity interest in Incuron, but maintain a right to royalty payments, as later described, and we conduct drug development activities on behalf of Incuron in the U.S. In September 2011, we created Panacela, a U.S. entity, with Joint Stock Company "Rusnano" ("Rusnano") to develop Mobilan and other product candidates (described below.) Simultaneous with the formation of Panacela, was the creation of a wholly-owned Russian subsidiary of Panacela named Panacela Labs, LLC. Finally, we had a wholly-owned Russian subsidiary, BioLab 612, LLC, that was dissolved in November 2020.

CBLI and Panacela each have development and commercialization rights to product candidates in development, subject to certain financial obligations to our current licensors.

In 2018, as discussed above, we formed GPI with Everon to undertake a research and development program aimed at clinical testing of entolimod and GP532 (a variant of our entolimod drug candidate) and the development of medications with anti-aging and other indications associated with genome damage.

The CBLI logo and CBLI product names are proprietary trade names of CBLI, its subsidiaries. We may indicate U.S. trademark registrations and U.S. trademarks with the symbols "®" and "™", respectively. Third-party logos and product/trade names are registered trademarks or trade names of their respective owners.

PRODUCT DEVELOPMENT PIPELINE

Our product development programs arise from both internally developed and in-licensed intellectual property from our innovation partners, The Cleveland Clinic and RPCI. In building the Company’s product development pipeline, we intentionally pursued targets with applicability across multiple therapeutic areas and indications. This approach gives us multiple product opportunities and ensures that our success is not dependent on any single product or indication. However, most of our efforts during the last four fiscal years have focused on developing entolimod's ARS indication.

Our currently ongoing product development programs and their respective development stages are illustrated below:

Our product development efforts were initiated by discoveries related to apoptosis, a tightly regulated form of cell death that can occur in response to internal stresses or external events such as exposure to radiation or toxic chemicals. Apoptosis is a major determinant of the tissue damage that occurs in a variety of medical conditions involving ischemia, or temporary loss of blood flow, such as cerebral stroke, heart attack and acute renal failure. In addition, apoptotic loss of cells of the hematopoietic system and gastrointestinal tract is largely responsible for the acute lethality of high-dose radiation exposure. On the other hand, apoptosis is also an important protective mechanism that allows the body to eliminate defective cells such as those with cancer-forming potential.

We have developed novel strategies to target the molecular mechanisms controlling apoptotic cell death for therapeutic benefit. These strategies take advantage of the fact that tumor and normal cells respond to apoptosis-inducing stresses differently due to tumor-specific defects in cellular signaling pathways such as inactivation of p53 (a pro-apoptosis regulator) and constitutive activation of Nuclear Factor kappa-B ("NF-kB"), (a pro-survival regulator).

Thus, we designed two oppositely-directed general therapeutic concepts:

In recent years, our understanding of the mechanisms of actions underlying the activity of these compounds has grown substantially beyond the initial founding concepts around modulation of apoptosis.

Entolimod Biodefense Indication

Our most advanced Protectan product candidate is entolimod, an engineered derivative of the Salmonella flagellin protein that was designed to retain its specific TLR5-activating capacity while increasing its stability, reducing its immunogenicity and enabling high-yield production. We are developing entolimod as a medical radiation countermeasure for reducing the risk of death from ARS, which we refer to as a Biodefense Indication.

The market for medical radiation countermeasures grew dramatically following the September 11, 2001 terrorist attacks and the subsequent use of anthrax in a biological attack in the U.S. Terrorist activities worldwide have continued in the intervening years and the possibility of chemical, biological, radiation and nuclear attacks continues to represent a perceived threat for governments world wide. In addition to the U.S. government, which maintains a national stockpile of products for emergency use (the "National Stockpile"), we believe the potential markets for the sale of radiation countermeasures include U.S. federal, state and local governments, including defense and public health agencies, foreign governments, non-governmental organizations, multinational corporations, transportation and security companies, healthcare providers, and nuclear power facilities.

Acute high-dose whole body or significant partial body radiation exposure induces massive apoptosis of cells of the hematopoietic system and gastrointestinal tract, which leads to ARS, a potentially fatal condition. The threat of ARS is primarily limited to emergency/defense scenarios and is significant given the possibility of nuclear/radiological accidents, warfare or terrorist incidents. The scale of possible exposure (number of people affected) has been estimated by the U.S. government to be in the range of 500,000 based on a modeled 10-kiloton device detonation in New York City. We believe the significant limitations of the three currently approved treatments to deal with such an event make entolimod a compelling product candidate. It is not feasible or ethical to test the efficacy of entolimod as a radiation countermeasure in humans. Therefore, we are developing entolimod under the FDA’s Animal Rule guidance (see "– Government Regulation – Animal Rule"). The Animal Rule authorizes the FDA to rely on data from animal studies to provide evidence of a product’s effectiveness under circumstances where there is a reasonably well-understood mechanism for the activity of the product. Under these requirements, and with the FDA’s prior agreement, medical countermeasures, like entolimod, may be approved for use in humans based on evidence of effectiveness derived from appropriate animal studies, evidence of safety derived from studies in humans and any additional supporting data.

Our pivotal efficacy study conducted in 179 non-human primates demonstrated with a high degree of statistical significance that injection of a single dose of entolimod given to rhesus macaques 25 hours after exposure to a 70% lethal dose of total body irradiation improved animal survival by nearly three-fold compared to the control group. Dose-dependence of entolimod’s efficacy was demonstrated with doses above the minimal efficacious dose establishing a plateau at approximately 75% survival at 60 days after irradiation, as compared to 27.5% survival in the placebo-treated group.

Our pivotal study conducted in 160 non-irradiated non-human primates established the dose-dependent effect of entolimod on biomarkers for animal-to-human dose conversion.

Our clinical studies of entolimod in 150 healthy human subjects demonstrated the safety profile of entolimod and established the dose-dependent effect of entolimod on efficacy biomarkers in humans. In these studies, and in the oncology studies in which more than 60 cancer patients have been administered to date, transient decrease in blood pressure and elevation of liver enzymes were observed along with transient mild to moderate flu-like syndrome. Such effects are the most common adverse events and they are linked to up-regulation of cytokines that are also biomarkers for efficacy.

As discussed above, we are seeking pre-EUA authorization from the FDA for entolimod, for which we submitted an application and have ongoing discussions with the FDA.

The FDA has granted Fast Track status to entolimod (see "– Government Regulation – Fast Track Designation") and Orphan Drug status for prevention of death following a potentially lethal dose of total body irradiation during or after a radiation disaster (see "– Government Regulation – Orphan Drug Designation").

Entolimod Oncology Indication

In addition to developing entolimod as a MRC for reducing the risk of death from ARS, we have initiated an evaluation of entolimod's potential to treat cancer by activating the innate and adaptive immune response in patients. In preclinical studies, entolimod produced tissue-specific activation of innate immune responses via interaction with its receptor, TLR5, and the liver was identified as a primary mediator of entolimod activity. Entolimod has also been shown to have a direct cytotoxic effect on tumors expressing TLR5 in animal models. Evaluations of local administration of entolimod in organs expressing TLR5, such as the bladder, have also been performed in animal models.

We completed a Phase 1 open-label, dose-escalation trial of entolimod in 26 patients with advanced cancer in the U.S. in 2015 and an extension study in additional patients in Russia receiving the entolimod drug product formulation proposed for commercialization is ongoing. The data for the U.S. study were presented at the 2015 annual meeting of ASCO. 26 patients with previously treated metastatic cancers, including colorectal, non-small cell lung, anal and urothelial bladder tumors were enrolled in the study. Stable disease for more than 6 weeks was observed in 8 patients with various cancer types; among these, 3 patients (with anal, colorectal and urothelial cancers) had maintenance of stable disease for more than 12 weeks. Patients exhibited CD8⁺ T-cell activation with stable or decreased levels of myeloid-derived suppressive cells, accompanied by increased immunostimulatory cytokines (G-CSF, IL-6, and IL-8). The tolerability profile in patients with advanced cancer was similar to that observed in two previously conducted studies in 150 healthy subjects receiving entolimod. As expected with activation of innate immune pathways, common adverse events were flu-like symptoms and fever, with some patients having transient, spontaneously resolving tachycardia, hypotension and hyperglycemia. Overall, treatment with entolimod was well tolerated.

In addition, we have conducted a clinical study of the safety and tolerability of entolimod as a neo-adjuvant therapy before cancer surgery in treatment-naïve patients with primary colorectal cancer. Because the study included older patients (up to 84 years) and those with other health conditions, the trial further extended an understanding of entolimod effects in a broader population of study patients. The safety profile of the drug appeared generally similar to the profiles previously identified in healthy subjects and patients with cancer who participated in prior studies. Increases in plasma cytokines and alterations of blood cells were observed that appeared consistent with TLR5-mediated mobilization and trafficking of immunocytes to peripheral tissues, although changes in tumor immune cell infiltration appeared to be independent of treatment group in this exploratory study.

In February 2016, we announced the publication of studies elucidating immunotherapeutic mechanisms through which entolimod suppresses metastasis in Proceedings of the National Academy of Sciences of the United States of America ("PNAS"). The studies presented in the PNAS publication decipher the cascade of cell-signaling events that are triggered by entolimod activation of the TLR5 pathway in the liver. The data also define the functional roles of natural killer ("NK"), dendritic, and CD8+ T-cells in the drug’s activity as a suppressor of metastasis. The studies demonstrate that entolimod administration induces chemokines that attract NK cells to the liver via a CXCR3-dependent mechanism. CXCR3 is a chemokine receptor that is highly expressed on both NK and effector T cells and plays an important role in cell trafficking to tissues. Once in the liver, NK cells, which are components of the innate immune system, engage an adaptive antitumor immune response through dendritic cell activation. This NK-to-dendritic cell interaction generates CD8+ T-cell-dependent antitumor memory that results in tumor rejection upon animal re-challenge with tumor. Importantly, localized antitumor effects in the liver combine with systemic responses that enable suppression of metastasis to the lung.

On August 6, 2018, we entered into a license agreement with GPI pursuant to which the Company licensed to GPI, on an exclusive basis, the right to develop, manufacture, commercialize, and sell entolimod in the field of use related to the prevention or treatment of any disease, disorder, or frailty in humans caused by aging, including treatment of "cancer survivors" (i.e., persons who are proclaimed to be "cancer free" at the time of treatment, but have been damaged by conventional cancer therapy). We retained the exclusive worldwide development and commercialization rights to entolimod for use as an ARS indication and concurrent radiation treatment of humans diagnosed with oncological conditions at the time of treatment.

Mobilan

Mobilan is the lead product candidate of Panacela. Mobilan is a recombinant non-replicating adenovirus that directs expression of TLR5 and its agonistic ligand, a secretory non-glycosylated version of entolimod. In preclinical studies, delivery of Mobilan to tumor cells results in constitutive autocrine TLR5 signaling and strong activation of the innate immune system with subsequent development of adaptive anti-tumor immune responses.

In 2016, Panacela completed enrollment of patients in a Phase 1 multicenter, randomized, placebo-controlled, single-blinded study in Russia evaluating single injections of ascending doses of Mobilan administered directly into the prostate of patients with prostate cancer.

Panacela holds exclusive worldwide development and commercialization rights to Mobilan.

As of December 31, 2020, we owned 67.57% of Panacela.

CBL0137

CBL0137 is a small molecule with a multi-targeted mechanism of action that may be broadly useful for the treatment of many different types of cancer and is being developed by Incuron. During 2015 we sold our remaining equity interest in Incuron but retain a 2% royalty on (a) product sales of CBL0137, (b) consideration received by Incuron from a licensee or sublicensee, and (c) consideration received in connection with the first change of control of Incuron. Incuron’s royalty obligations continue until April 29, 2025.

CBL0137 may offer greater efficacy and substantially lower risk for the development of drug resistance than conventional chemotherapeutic agents. CBL0137 inhibits MYC protein, NF-kB, Heat Shock Factor Protein-1 ("HSF-1"), and Hypoxia-inducible factor 1-alpha; these are transcription factors that are important for the viability of many types of tumors. The drug also activates tumor suppressor protein p53 by modulating intracellular localization and activity of chromatin remodeling complex Facilitates Chromatin Transcription ("FACT"). CBL0137 has been shown to be efficacious in animal models of colon, lung, breast, renal, pancreatic, head and neck and prostate cancers; melanoma; glioblastoma; and neuroblastoma. It has also been shown to be efficacious in animal models of hematological cancers, including lymphoma, leukemia and multiple myeloma.

Incuron holds worldwide development and commercialization rights to CBL0137.

STRATEGIC PARTNERSHIPS

Since our inception, strategic alliances and collaborations have been integral to our business. We have exclusively licensed rights in each of our technologies from The Cleveland Clinic and RPCI and maintain innovative partnerships with each. We have also leveraged the experience, contacts and knowledge of our founders to engage financial partners in Russia. Through these partnerships we have collaborated with scientists from other countries to develop our novel technologies and accessed non-traditional funding sources, including U.S. federal and foreign government contracts and project-oriented funding. We have received project-oriented funding from Rusnano through the formation of Panacela.

Panacela maintains operations in Russia and benefits from programs supporting domestic pharmaceutical industry development in Russia.

The Cleveland Clinic

In July 2004, CBLI entered into an exclusive license agreement with The Cleveland Clinic ("The Cleveland Clinic License") pursuant to which CBLI was granted an exclusive license to The Cleveland Clinic’s research base underlying our therapeutic platform. We amended The Cleveland Clinic License, effective as of September 22, 2011, pursuant to which we were granted an exclusive license to The Cleveland Clinic’s research base underlying certain product candidates in development by Panacela ("Panacela Products"), including Mobilan and several earlier-stage compounds that are not currently material to our business.

In consideration for The Cleveland Clinic License, we agreed to issue The Cleveland Clinic common stock and make certain milestone, royalty, and sublicense royalty payments as described below.

The Cleveland Clinic License requires milestone payments, which may be credited against future royalties owed to The Cleveland Clinic, as described in the table below.

We have also agreed to make milestone payments of up to approximately $6.5 million for each Panacela Product that achieves certain developmental and regulatory milestones, provided that if CBLI or an affiliate of CBLI and The Cleveland Clinic jointly own the Panacela Product, the milestone amounts will be reduced by 50%.

The Cleveland Clinic License requires royalty payments of (a) 2% of net sales of any product candidate under a licensed patent solely owned by The Cleveland Clinic; and (b) 1% of net sales of any product candidate under a licensed patent that is jointly owned by The Cleveland Clinic and CBLI or an affiliate of CBLI. Further, if CBLI receives upfront sublicense fees or sublicense royalty payments for sublicenses granted by CBLI to third parties for any licensed patents solely owned by The Cleveland Clinic, CBLI will pay The Cleveland Clinic (i) 35% of such fees if the sublicense is granted prior to filing an IND application, (ii) 20% of such fees if the sublicense is granted after an IND filing but prior to final approval of the Product License Application or NDA, or (iii) 10% of such fees if the sublicense is granted after final approval of the relevant Product License Application or NDA, provided that such sublicense fees shall not be less than 1% of net sales. The above sublicense fees and sublicense royalty payments are reduced by 50% if The Cleveland Clinic and CBLI or an affiliate of CBLI jointly own the licensed patent.

Through December 31, 2020, CBLI had paid The Cleveland Clinic $150,000 for milestone payments on products limited to biodefense uses, and $400,000 for all other products.

Roswell Park Cancer Institute

We have entered into a number of agreements with RPCI relating to the licensure and development of our product candidates including:

In December 2007, CBLI entered into an agreement with RPCI pursuant to which CBLI has an option to exclusively license any technological improvements to our foundational technology developed by RPCI for the term of the agreement. We believe our option to license additional technology under the agreement potentially provides us with access to technology that may supplement our product pipeline in the future. In consideration for this option and exclusive license, we agreed to make certain milestone, royalty and sublicense royalty payments.

In September 2011, Panacela entered into an agreement with RPCI (the "Panacela-RPCI License") to exclusively license from RPCI certain rights to the Panacela Products, including Mobilan and several earlier-stage compounds that are not currently material to our business, and to non-exclusively license from RPCI certain know-how relating to the aforementioned product candidates for the limited purposes of research and development and regulatory, export and other government filings. Additionally, under the Panacela-RPCI License, Panacela has a right to exclusively license from RPCI (i) any technological improvements to the Panacela

Products developed by RPCI before September 2016, and (ii) any technology jointly developed by Panacela and RPCI. In consideration for the Panacela-RPCI License, Panacela agreed to issue RPCI common stock and to make certain milestone, royalty and sublicense royalty payments as described below.

The Panacela-RPCI License requires milestone payments for developmental and regulatory milestones reached in the U.S. of up to approximately $2.5 million for each Panacela Product that achieves certain developmental and regulatory milestones. Additionally, Panacela will owe additional payments of up to approximately $275,000 for each other country where a licensed Panacela Product achieves similar milestones.

The Panacela-RPCI License requires royalty payments on net sales based on percentages in the low single digits. In addition, if Panacela sublicenses any of the licensed Panacela Products, Panacela will owe sublicensing fees ranging from 5% to 15% of any fees received from the sublicensee by Panacela or an affiliate depending upon whether or not an IND has been filed or final approval of the relevant NDA has been obtained for such licensed product.

We have also entered into a number of sponsored research agreements with RPCI pursuant to which both parties have sponsored research to be conducted by the other party. Under our sponsored research agreement with RPCI, title to any inventions under the agreement is determined in a manner substantially similar to U.S. patent law, and we have the option to license from RPCI, on an exclusive basis, the right to develop any inventions of RPCI (whether solely or jointly developed) under the agreement for commercial purposes.

Under the sponsored research agreements with RPCI, we own any invention that is described in our research plan, co-own any inventions not described in our research plan that are made by Dr. Andrei Gudkov, our Chief Scientific Officer, and RPCI owns any other inventions not described in our research plan. We further have a right to exclusively license from RPCI any invention developed under such sponsored research agreements that are owned by RPCI. Such sponsored research agreements with RPCI expired in 2019.

We entered into an asset transfer and clinical trial agreement with RPCI for the conduct, by RPCI, of our Phase 1 clinical trial to evaluate the safety and pharmacokinetic profile of entolimod in patients with advanced cancers, which has now been largely completed.

Rusnano

In 2011, we formed Panacela with Rusnano to carry out a complete cycle of development and commercialization of medications in Russia for the treatment of oncological, infectious or other diseases. We invested $3.0 million in Panacela preferred shares and warrants, and, together with certain third-party owners, assigned and/or exclusively licensed, as applicable, to Panacela worldwide development and commercialization rights to five preclinical product candidates in exchange for Panacela common shares. Rusnano invested $9.0 million in Panacela preferred shares and warrants. In 2013, Rusnano loaned Panacela $1.5 million through a convertible term loan (the "Panacela Loan"). In December of 2015, together with Rusnano, we recapitalized Panacela to fully retire the Panacela Loan and certain other trade payables. Rusnano maintained its ownership percentage in Panacela, while CBLI's ownership stake grew to 66.77%. As of December 31, 2020, we had an ownership stake of approximately 67.57%.

Everon Biosciences

On August 6, 2018, we entered into a series of transactions with our joint venture, GPI, and Everon. GPI was formed by the Company to undertake a research and development program aimed at clinical testing of entolimod and GP532 (a variant of our entolimod drug candidate) and to develop medications with anti-aging and other indications associated with genome damage. Under the terms of a license agreement entered into with GPI, we agreed to license to GPI, on an exclusive basis, the right to develop, manufacture, commercialize, and sell products utilizing the Company’s intellectual property underlying the Company’s entolimod drug candidate, solely in the field of use related to the prevention or treatment of any disease, disorder, or frailty in humans caused by aging. Entolimod’s use as an acute radiation treatment medication is retained by the Company under the license agreement. The intellectual property is licensed pursuant is separate licenses; the license of our intellectual property underlying entolimod’s oncology indication is being licensed on a paid-up, royalty-free basis while the license of our intellectual property underlying entolimod’s composition is being granted on a fee-bearing and royalty-bearing basis, with such fees and royalties comprising those included in the original license agreement pursuant to which we originally licensed such intellectual property from The Cleveland Clinic Foundation, with such fees and royalties payable to The Cleveland Clinic Foundation.

Under the license agreement, GPI retains responsibility for its own development and commercialization activities but is required to provide us with access to all clinical, safety, and other data arising from its development activities. We must disclose and transfer all of our know-how pertaining to the licensed intellectual property and provide entolimod product samples to GPI for use in GPI’s clinical trials. The license agreement requires the parties to work together to coordinate efforts between them with respect to regulatory filings, proper reporting of adverse events, the development of standard clinical and quality assurance operating procedures, and the amount of product to be supplied by us to GPI for the conduct of GPI’s development activities.

We also entered into an assignment agreement with GPI, under which we assigned certain intellectual property underlying our GP532 product candidate and our entolimod vaccine product candidate and GPI licensed back to us, on an exclusive, irrevocable basis, the right to develop manufacture, commercialize, and sell products relating to the assigned intellectual property for use as a medical countermeasure to treat acute radiation exposure or as a cancer treatment. Under the terms of the assignment, we retain responsibility for our own development and commercialization activities, but GPI is required to use commercially reasonable efforts to supply to us at no surcharge the number of product samples that it has available for clinical trials that we sponsor and necessary in connection with our efforts to obtain regulatory approval for any drug candidates. The assignment requires us to pay a royalty to GPI of 2% of our net sales of any products covered by or using the assigned intellectual property subject to the license-back in each calendar year beginning on the date of the first commercial sale of any such product until patent protection is no longer available for the assigned intellectual property in the U.S., France, Germany, Italy, Japan, Spain, or the United Kingdom. We are further required to make payments to GPI upon the achievement of certain milestones in the development of product candidates utilizing the licensed intellectual property.

As consideration for the licenses granted to GPI and the assignment of the intellectual property to GPI, GPI issued to the Company 1,000 shares of GPI’s common stock. Contemporaneously with the Company’s entry into the license and assignment, Everon contributed certain of its intellectual property related to the potential development of treatments that address serious medical needs associated with human aging to GPI, also in exchange for 1,000 shares of GPI’s common stock. As a result of each of the Company’s and Everon’s receipt of 1,000 shares of GPI’s common stock, each of the Company and Everon became the owner of 50% of all of the outstanding capital stock of GPI. Additionally, in exchange for providing funding, Norma, a venture capital fund, has the right to acquire shares of GPI’s capital stock in the future. We currently own 50% of the outstanding capital stock of GPI.

INTELLECTUAL PROPERTY

Our intellectual property consists of patents, trademarks, trade secrets, and know-how. Our ability to compete effectively depends in large part on our ability to obtain patents for our technologies and products, maintain trade secrets, operate without infringing the rights of others, and prevent others from infringing our proprietary rights. We will be able to protect our proprietary technologies from unauthorized use by third parties only to the extent that they are covered by valid and enforceable patents, or are effectively maintained as trade secrets. As a result, patents or other proprietary rights are an essential element of our business. Our patent portfolio includes patents and patent applications with claims directed to compositions of matter, pharmaceutical formulations, and methods of use. Some of our issued patents, and the patents that may be issued based on our patent applications, may be eligible for patent life extension under the Drug Price Competition and Patent Term Restoration Act of 1984 in the U.S., supplementary protection certificates in the European Union ("E.U.") or similar mechanisms in other countries or territories. The following are the patent positions relating to our product candidates as of December 31, 2020.

In the U.S., we have 25 issued patents or allowed patent applications relating to our clinical-stage programs expiring on various dates between 2024 and 2032 as well as numerous pending patent applications and foreign counterpart patent filings which relate to our proprietary technologies. These patents and patent applications include claims directed to compositions of matter and methods of use.

We have 22 issued or allowed U.S. patents covering entolimod, which expire between 2024 and 2032. These patents include composition of matter claims, as well as method of use claims relating to our biodefense and oncology indications, reducing effects of chemotherapy, and treatment of reperfusion injuries. In addition, we have pending U.S. patent applications related to compositions of matter, oncology methods of use, and others biodefense methods, which, if issued, will expire between 2025 and 2035.

We have 2 issued or allowed U.S. patents covering CBLB612 and related agents, which expire between 2026 and 2027. These patents include composition of matter and methods of use claims.

We have one issued U.S. patent covering compositions of matter for various vectors, including Mobilan, which expires in 2032. We also have issued or allowed patents covering Mobilan and related agents, which expire in 2030 that cover a broad list of international territories including the E.U., Australia, Japan, and Russia.  These patents include composition of matter and methods of use claims.

In addition, as of December 31, 2020, we have approximately 35 additional patents and patent applications filed worldwide. Any patents that may issue from our pending patent applications would expire between 2024 and 2035, excluding patent term extensions. These patents and patent applications disclose compositions of matter and methods of use.

Our policy is to seek patent protection for the inventions that we consider important to the development of our business. We intend to continue to file patent applications to protect technology and compounds that are commercially important to our business, and to do so in countries where we believe it is commercially reasonable and advantageous to do so. We also rely on trade secrets to protect our technology where patent protection is deemed inappropriate or unobtainable. We protect our proprietary technology and processes, in part, by confidentiality agreements with our employees, consultants, collaborators, and contractors.

RESEARCH AND DEVELOPMENT

As of December 31, 2020, our research and development group, including Russian-based personnel, consisted of 2 individuals. Our research and development focuses on management of outsourced preclinical research, clinical trials, and manufacturing technologies. We invested $0.7 million and $1.7 million in research and development during the years ended December 31, 2020 and 2019, respectively.

SALES AND MARKETING

We currently do not have marketing, sales, or distribution capabilities. We do, however, currently have worldwide development and commercialization rights for products arising out of substantially all of our programs, as discussed above. In order to commercialize any of these drugs, if and when they are approved for sale, we will need to enter into partnerships for the commercialization of the approved product(s) or develop the necessary marketing, sales, and distribution capabilities.

COMPETITION

The biotechnology and biopharmaceutical industries are characterized by rapid technological developments and intense competition. This competition comes from both biotechnology and major pharmaceutical companies. Many of these companies have substantially greater financial, marketing, and human resources than we do, including, in some cases, considerably more experience in clinical testing, manufacturing, and marketing of pharmaceutical products. There are also academic institutions, governmental agencies, and other research organizations that are conducting research in areas in which we are working. They may also develop products that may be competitive with our product candidates, either on their own or through collaborative efforts. We expect to encounter significant competition for any products we develop. Our product candidates’ competitive position among other biotechnology and biopharmaceutical companies will be based on, among other things, time to market, patent position, efficacy, safety, reliability, availability, patient convenience, ease of delivery, manufacturing cost, and price. In these cases, we may not be able to commercialize our product candidates or achieve a competitive position in the market. This would adversely affect our business.

Specifically, the competition for entolimod and our other clinical-stage product candidates includes the following:

Entolimod Biodefense Indication

Product candidates for treatment of ARS face significant competition for U.S. government funding for both development and procurement of medical countermeasures and must satisfy government procurement requirements for biodefense products. Currently the only FDA-approved drugs for the treatment of ARS are filgrastim (Neupogen™) peg-filgrastim (Neulasta™) and sargramostim (Leukine®). Filgrastim (granulocyte colony-stimulating factor ("GCS-F") and peg-filgrastim (PEGylated form of GCS-F) stimulate neutrophils and may reduce infection related to ARS. Unlike entolimod, these drugs do not improve platelet counts or lessen bleeding, and do not ameliorate gastrointestinal dysfunction due to ARS. Sargramostim is a leukocyte growth factor which induces partially committed hematopoietic progenitor cells to divide and differentiate in the granulocyte-macrophage pathways which include neutrophils and other hematopoietic cell types. In label-supporting survival studies, all three products required repeated administration  and treatment was accompanied by laboratory monitoring. In addition, filgrastim and peg-filgrastim required intensive supportive care (including platelet transfusions). By contrast, entolimod survival studies included only a single injection, without laboratory monitoring and without any intensive medical support, which we believe makes it significantly more suitable for use in a mass-casualty situation.

The U.S. government has purchased several colony-stimulating factors to treat injuries to bone marrow in victims of radiological or nuclear accidents or acts of terrorism for the National Stockpile. In 2013, it paid $157 million to Amgen USA, Inc. for 541,000 doses of Neupogen® and $37 million to Sanofi-Aventis U.S., LLC for 66,000 doses of Leukine® (granulocyte-macrophage colony-stimulating factor). In October 2016, the U.S. government purchased an additional $37.6 million worth of Leukine® and peg-filgrastim, Neulasta®, from Amgen USA, Inc., for another $37.7 million. The U.S government also announced that it continues to work with Sanofi-Aventis to support the studies needed to request FDA approval of Leukine®. These purchases were made using funding and authority provided through the Project BioShield Act of 2004. Under the Project BioShield Act, the U.S. government supports the advanced development and procurement of new medical countermeasures - drugs, vaccines, diagnostics, and medical supplies - to protect health against chemical, biological, radiological, and nuclear threats.

In addition to the colony-stimulating factors, we are aware of a number of companies also developing radiation countermeasures to treat the effects of ARS including: Aeolus Pharmaceuticals, Araim Pharmaceuticals, Inc., Cellerant Therapeutics, Inc., Humanetics Corporation, Neumedicines, Inc., Pluristem Therapeutics, Inc, RxBio, Inc., and Soligenix, Inc. Although their approaches to treatment of ARS are different, we compete with these companies for U.S. government development funding and may ultimately compete with them for U.S. and foreign government purchase and stockpiling of radiation countermeasures.

Additionally, our ability to sell to the government also can be influenced by competition from the products, such as Neupogen®, Neulasta®, and Leukine®, which were previously purchased by the U.S. government for the National Stockpile.

Entolimod Immuno-Oncology Program and Mobilan

Immunotherapies are major drivers of commercial growth in cancer therapy and constitute the primary competition for a potential immunotherapeutic agent like entolimod or Mobilan. Examples of marketed drugs in these categories include: pembrolizumab (Keytruda®) (Merck) indicated for advanced melanoma, metastatic non-small cell lung cancer ("NSCLC"), recurrent or metastatic head and neck squamous cell carcinoma, refractory classical Hodgkin lymphoma, and urothelial carcinoma; nivolumab (Opdivo®) (Bristol-Myers Squibb Company) for advanced melanoma and metastatic squamous NSCLC, hepatocellular carcinoma, head and neck squamous cell carcinoma, renal cell carcinoma, classical Hodgkin lymphoma, urothelial carcinoma, and high or mismatch repair deficient metastatic colorectal cancer; ipilimumab (Yervoy®) (Bristol-Myers Squibb) of unresectable or metastatic melanoma, and for non-muscle-invasive bladder cancer. These drugs may be appropriate combination partners for entolimod or Mobilan in the appropriate treatment settings. However, these drugs may also be competitors for the market share in the treatment of various tumor types.

MANUFACTURING

Our product candidates are biologics and small molecules that can be readily synthesized by processes that we have developed. We do not own or operate manufacturing facilities for the production of our product candidates for preclinical, clinical, or commercial quantities. We rely on third-party manufacturers, and in most cases only one third-party, Wacker Biotech B.V., to manufacture critical raw materials, drug substance and final drug product for our research, preclinical development, and clinical trial activities. Commercial quantities of any drugs we seek to develop will have to be manufactured in facilities and by processes that comply with the FDA and other regulations, and we plan to rely on third parties to manufacture commercial quantities of products we successfully develop.

GOVERNMENT REGULATION

Government authorities in the U.S. and in other countries regulate the research, development, testing, manufacture, packaging, storage, record-keeping, promotion, advertising, distribution, marketing, quality control, labeling, and export and import of pharmaceutical products such as those that we are developing. We cannot provide assurance that any of our product candidates will prove to be safe or effective, will receive regulatory approvals, or will be successfully commercialized.

U.S. Drug Development Process

In the U.S., the FDA regulates drugs and drug testing under the Federal Food, Drug, and Cosmetic Act and in the case of biologics, also under the Public Health Service Act. Our product candidates must follow processes consistent with these laws before they may be marketed in the U.S.:

Nonclinical testing. Nonclinical testing includes laboratory evaluation of a product candidate, its chemistry, formulation, safety and stability, as well as animal studies to assess the potential safety and efficacy of the product candidate. The conduct of the nonclinical tests must comply with federal regulations and requirements including cGMP and GLP. Prior to the initiation of GLP animal studies, including our pivotal studies for development of entolimod under the Animal Rule, an Institutional Animal Care and Use Committee ("IACUC") at each testing site must review and approve each study protocol and any amendments thereto.

We must submit to the FDA the results of nonclinical studies, which may include laboratory evaluations and animal studies, together with manufacturing information and analytical data, and the proposed clinical protocol for the first clinical trial of the drug as part of an IND. An IND is a request for FDA authorization to administer an investigational drug to humans. Such authorization must be secured prior to the interstate shipment and administration of any new drug that is not the subject of an approved pre-EUA, NDA, or BLA. Nonclinical tests and studies can take several years to complete, and despite completion of those tests and studies, the FDA may not permit clinical testing to begin.

The IND process. The FDA requires a 30-day waiting period after the submission of an IND application before clinical trials may begin. This waiting period is designed to allow the FDA to review the IND to determine whether human research subjects will be exposed to unreasonable health risks. At any time during this 30-day period or at any time thereafter, the FDA may raise concerns or questions about the conduct of the trials as outlined in the IND and impose a "clinical hold" that may affect one or more specific studies, or all studies conducted under the IND. In the case of a clinical hold, the IND sponsor and the FDA must resolve any outstanding concerns before clinical trials placed on hold can begin or continue. The IND application process may be extremely costly and could substantially delay development of our products. Moreover, positive results of preclinical animal tests do not necessarily indicate positive results in clinical trials.

Prior to the initiation of each clinical study, the corresponding clinical protocol must be submitted as part of the IND and to an independent Institutional Review Board ("IRB") at each medical site proposing to conduct the clinical trial. The IRB must review and approve each study protocol, and any amendments thereto, and study subjects must sign an informed consent. Protocols include, among other things, the objectives of the study, dosing procedures, subject selection, and exclusion criteria and the parameters to be used to monitor patient safety. Progress reports of work performed in support of IND studies must be submitted at least annually to the FDA. Reports of serious, unexpected, and related adverse events must be submitted to the FDA and the investigators in a timely manner.

Clinical trials. Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:

We cannot be certain that we will successfully complete any phase of clinical testing of our product candidates within any specific time period, if at all. Clinical testing must meet the requirements of IRB oversight, informed consent and GCP. The FDA, the sponsor, or the IRB at each institution at which a clinical trial is being performed may suspend a clinical trial at any time for various reasons, including a belief that the participants are being exposed to an unacceptable health risk.

During the development of a new drug, sponsors are given an opportunity to meet with the FDA at certain points. These meetings typically occur prior to submission of an IND, at the end of Phases 1 and 2 and before NDA or BLA submission. These meetings can provide an opportunity for the sponsor to share information about the data gathered to date, for the FDA to provide advice, and for the sponsor and FDA to reach agreement on the next phase of development. Sponsors typically use the end-of-Phase 2 meeting to discuss their Phase 2 clinical results and present their plans for the pivotal Phase 3 clinical trial that they believe will support approval of the new drug.

The NDA or BLA process. If clinical trials are successful, the next step in the drug regulatory approval process is the preparation and submission to the FDA of an NDA or BLA, as applicable. The NDA or BLA, as applicable, is a vehicle through which drug sponsors formally propose that the FDA approve a new pharmaceutical for marketing and sale in the U.S. The NDA or BLA, as applicable, must contain a description of the manufacturing process and quality control methods, as well as results of preclinical tests, toxicology studies, clinical trials and proposed labeling, among other things. A substantial user fee must also be paid with the application, unless an exemption applies. Every newly marketed pharmaceutical must be the subject of an approved NDA or BLA.

Upon submission of an NDA or BLA, the FDA will make a threshold determination of whether the application is sufficiently complete to permit review, and, if not, will issue a refuse-to-file letter. If the application is accepted for filing, the FDA will attempt to review and take action on the application in accordance with performance goal commitments the FDA has made in connection with the prescription drug user fee law in effect at that time. Current timing commitments under the user fee law vary depending on whether an NDA or BLA is for a priority drug or not, and in any event are not a guarantee that an application will be approved or even acted upon by any specific deadline. The review process is often significantly extended by FDA requests for additional information or clarification. The FDA may refer the NDA or BLA to an advisory committee for review, evaluation and recommendation as to whether the application should be approved, but the FDA is not bound by the recommendation of an advisory committee. The FDA may deny or delay approval of applications that do not meet applicable regulatory criteria or if the FDA determines that the data do not adequately establish the safety and efficacy of the drug. In addition, the FDA may approve a product candidate subject to the completion of post-marketing studies, commonly referred to as Phase 4 trials, to monitor the effect of the approved product. The FDA may also grant approval with restrictive product labeling or may impose other restrictions on marketing or distribution such as the adoption of a Risk Evaluation and Mitigation Strategies ("REMS").

Manufacturing and post-marketing requirements. If approved, a pharmaceutical may only be marketed in the dosage forms and for the indications approved in the NDA or BLA, as applicable. Special requirements also apply to any samples that are distributed in accordance with the Prescription Drug Marketing Act. The manufacturers of approved products and their manufacturing facilities are subject to continual review and periodic inspections by the FDA and other authorities where applicable, and must comply with ongoing requirements, including the FDA’s GMP requirements. Once the FDA approves a product, a manufacturer must provide certain updated safety and efficacy information, submit copies of promotional materials to the FDA, and make certain other required reports. Product and labeling changes, as well as certain changes in a manufacturing process or facility or other post-approval changes, may necessitate additional FDA review and approval. Failure to comply with the statutory and regulatory requirements subjects the manufacturer to possible legal or regulatory action, such as untitled letters, warning letters, suspension of manufacturing, seizure of product, voluntary recall of a product, injunctive action or possible criminal or civil penalties. Product approvals may be withdrawn if compliance with regulatory requirements is not maintained or if problems concerning safety or efficacy of the product occur following approval. Because we intend to contract with third parties for manufacturing of our products, our ability to control third-party compliance with FDA requirements will be limited to contractual remedies and rights of inspection. Failure of third-party manufacturers to comply with GMP or other FDA requirements applicable to our products may result in, among other things, total or partial suspension of production, failure of the government to grant approval for marketing, and withdrawal, suspension, or revocation of marketing approvals. With respect to post-market product advertising and promotion, the FDA imposes a number of complex regulations on entities that advertise and promote pharmaceuticals, which include, among others, standards for direct-to-consumer advertising, promoting drugs for uses or in patient populations that are not described in the drug’s approved labeling (known as "off-label use"), industry-sponsored scientific and educational activities, and promotional activities involving the Internet. Failure to comply with FDA requirements can have negative consequences, including adverse publicity, enforcement letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties. Although physicians may prescribe legally available drugs for off-label uses, manufacturers may not market or promote such off-label uses.

The FDA’s policies may change, and additional government regulations may be enacted which could prevent or delay regulatory approval of our potential products. We cannot predict the likelihood, nature or extent of adverse governmental regulation that might arise from future legislative or administrative action, either in the U.S. or abroad.

Animal Rule

In 2002, the FDA amended its requirements applicable to BLAs/NDAs to permit the approval of certain drugs and biologics that are intended to reduce or prevent serious or life-threatening conditions based on evidence of safety from clinical trial(s) in healthy subjects and effectiveness from appropriate animal studies when human efficacy studies are not ethical or feasible. These regulations, which are known as the "Animal Rule", authorize the FDA to rely on animal studies to provide evidence of a product’s effectiveness under circumstances where there is a reasonably well-understood mechanism for the activity of the agent. Under these requirements, and with the FDA’s prior agreement, drugs used to reduce or prevent the toxicity of chemical, biological, radiological, or nuclear substances may be approved for use in humans based on evidence of effectiveness derived from appropriate animal studies and any additional supporting data. Products evaluated under this rule must demonstrate effectiveness through pivotal animal studies, which are generally equivalent in design and robustness to Phase 3 clinical studies. The animal study endpoint must be clearly related to the desired benefit in humans and the information obtained from animal studies must allow for selection of an effective dose in humans. Safety under this rule is established under preexisting requirements, including safety studies in both animals (toxicology) and humans. Products approved under the Animal Rule are subject to additional requirements including post-marketing study requirements, restrictions imposed on marketing or distribution and requirements to provide information to patients.

We intend to utilize the Animal Rule in seeking marketing approval for entolimod as a medical radiation countermeasure because we cannot ethically expose humans to lethal doses of radiation. Other countries may not at this time have established criteria for review and approval of these types of products outside their normal review process, i.e. there is no "Animal Rule" equivalent in countries other than the U.S., but some may have similar policy objectives in place for these product candidates. Given the nature of nuclear and radiological threats, we do not believe that the lack of established criteria for review and approval of these types of products in other countries will significantly inhibit us from pursuing sales of entolimod to foreign countries.

All data obtained from the preclinical studies and clinical trials of entolimod, in addition to detailed information on the manufacture and composition of the product, would be submitted in a BLA to the FDA for review and approval for the manufacture, marketing, and commercial shipment of entolimod.

Emergency Use Authorization

The Commissioner of the FDA, under delegated authority from the Secretary of the U.S. Department of Health and Human Services ("DHHS") may, under certain circumstances, issue an Emergency Use Authorization ("EUA") that would permit the use of an unapproved drug product or unapproved use of an approved drug product. Before an EUA may be issued, the Secretary must declare an emergency based on one of the following grounds:

In order to be the subject of an EUA, the FDA Commissioner must conclude that, based on the totality of scientific evidence available, it is reasonable to believe that the product may be effective in diagnosing, treating or preventing a disease attributable to the agents described above, that the product’s potential benefits outweigh its potential risks and that there is no adequate approved alternative to the product.

Although an EUA cannot be issued until after an emergency has been declared by the Secretary of DHHS, the FDA strongly encourages an entity with a possible candidate product, particularly one at an advanced stage of development, to contact the FDA center responsible for the candidate product before a determination of actual or potential emergency. Such an entity may submit a request for consideration that includes data to demonstrate that, based on the totality of scientific evidence available, it is reasonable to believe that the product may be effective in diagnosing, treating, or preventing the serious or life-threatening disease or condition. This is called a pre-EUA submission and its purpose is to allow FDA review considering that during an emergency, the time available for the submission and review of an EUA request may be severely limited.

We submitted a pre-EUA in 2015 in order to inform and expedite the FDA’s issuance of an EUA, should one become necessary in the event of an emergency. The FDA does not have review deadlines with respect to pre-EUA submissions. Additionally, there is no guarantee that the FDA will agree that entolimod meets the criteria for EUA, or, if they do agree, that such agreement by the FDA will lead to procurement by the U.S. or other governments or further development funding.

Public Readiness and Emergency Preparedness Act

The Public Readiness and Emergency Preparedness Act (the "PREP Act"), provides immunity for manufacturers from all claims under state or federal law for "loss" arising out of the administration or use of a "covered countermeasure." However, injured persons may still bring a suit for "willful misconduct" against the manufacturer under some circumstances. "Covered countermeasures" include security countermeasures and "qualified pandemic or epidemic products", including products intended to diagnose or treat pandemic or epidemic disease, such as pandemic vaccines, as well as treatments intended to address conditions caused by such products. For these immunities to apply, the Secretary of DHHS must issue a declaration in cases of public health emergency or "credible risk" of a future public health emergency. Since 2007, the Secretary of DHHS has issued nine declarations under the PREP Act to protect countermeasures that are necessary to prepare the nation for potential pandemics or epidemics from liability. We believe, in the event of an emergency, were the FDA to issue an EUA for entolimod, it would receive protection under the terms of the PREP Act.

Fast Track Designation

Entolimod has been granted Fast Track designation by the FDA for reducing the risk of death following total body irradiation. The FDA’s Fast Track designation program is designed to facilitate the development and review of new drugs, including biological products that are intended to treat serious or life-threatening conditions and that demonstrate the potential to address unmet medical needs for the conditions. Fast Track designation applies to a combination of the product and the specific indication for which it is being studied. Thus, it is the development program for a specific drug for a specific indication that receives Fast Track designation. The sponsor of a product designated as being in a Fast Track drug development program may engage in early communication with the FDA, including timely meetings and early feedback on clinical trials and may submit portions of an NDA or BLA on a rolling basis rather than waiting to submit a complete application. Products in Fast Track drug development programs also may receive priority review or accelerated approval, under which an application may be reviewed within six months after a complete NDA or BLA is accepted for filing or sponsors may rely on a surrogate endpoint for approval, respectively. The FDA may notify a sponsor that its program is no longer classified as a Fast Track development program if the Fast Track designation is no longer supported by emerging data or the designated drug development program is no longer being pursued. Receipt of Fast Track designation does not guarantee that we will experience a faster development process, review or approval as compared to conventional FDA procedures or that we will qualify or be able to take advantage of the FDA’s expedited review procedures.

Orphan Drug Designation

Entolimod has been granted Orphan Drug designation by the FDA for prevention of death following a potentially lethal dose of total body irradiation. Under the Orphan Drug Act, the FDA may grant orphan drug designation to a drug intended to treat a rare disease or condition which is defined as one affecting fewer than 200,000 individuals in the U.S. or more than 200,000 individuals where there is no reasonable expectation that the product development cost will be recovered from product sales in the U.S. Orphan Drug designation must be requested before submitting an NDA or BLA and does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

If an Orphan Drug-designated product subsequently receives the first FDA approval for the disease for which it has such designation, the product will be entitled to orphan product exclusivity, which means that the FDA may not approve any other applications to market the same drug for the same indication, except in very limited circumstances for seven years as compared to five years for a standard new drug approval. As referenced above, we have received Orphan Drug designation for entolimod. We intend to seek Orphan Drug designation for our other products as appropriate, but an Orphan Drug designation may not provide us with a material commercial advantage.

Foreign Drug Development and Approval Regulation

In addition to regulations in the U.S., we are and will be subject to a variety of foreign regulations governing clinical trials and will be subject to a variety of foreign regulation governing commercial sales and distribution of our products. Whether or not we obtain FDA approval for a product, we must obtain approval by the comparable regulatory authorities of foreign countries before we can commence clinical trials or marketing of the product in those countries. The approval process varies from country to country and the time may be longer or shorter than that required for FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing, and reimbursement vary greatly from country to country. To our knowledge, other countries, at this time, do not have an equivalent to the Animal Rule and, as a result, do not have established criteria for review and approval of these types of products outside their normal review process, but some countries may have similar policy objectives in place for these product candidates.

Russian Drug Development and Approval Regulations. Our Russian activities are regulated by the Ministry of Health of the Russian Federation ("Minzdrav"). This federal executive authority is responsible for developing state policies as well as normative and legal regulations in the healthcare and pharmaceutical industries, including policies and regulations regarding the quality, efficacy and safety of pharmaceutical products.

In addition, the Federal Service on Surveillance in Healthcare and Social Development of the Russian Federation, known as Roszdravnadzor, is the executive authority subordinated to Minzdrav, which, among other things, (i) performs control and surveillance of certain activities, including preclinical and clinical trials, and monitors compliance with the state standards for medical products and pharmaceutical activities; (ii) issues licenses for the manufacture of drug products and pharmaceutical activities; (iii) grants allowance for clinical trials, use of new medical technologies and import and export of medical products, including import of products for use in clinical trials; and (iv) reviews and grants or denies registrations of medical products for sale in Russia.

The principal statute that governs our activities in Russia is the Federal Law No. 61-FZ "On Medicine Circulation" of April 12, 2010 (as amended). This law regulates the research, development, testing, preclinical and clinical studies, state registration, quality control, manufacture, storage, transporting, export and import, licensing, advertisement, sale, transfer, utilization and destruction of medical products within Russia, among other things. All medical products must be registered in Russia and comply with stringent safety and quality controls and testing.

In addition, our activities are subject to a number of other Russian laws, regulations and orders relating to the drug development activities, taxation, corporate governance, employment and other areas. In particular, the incorporation, corporate governance, shareholders' rights, and contractual matters related to our Russian subsidiaries and joint ventures are governed by the Civil Code of the Russian Federation and the Federal Law No. 14-FZ "On Limited Liability Companies" of February 8, 1998 (as amended). In accordance with this legislation we must comply with certain shareholders’ and board of directors’ approval requirements, including those applicable to major and interested party transactions.

Also, pursuant to the Russian Labor Code, our Russian subsidiaries and joint ventures must enter into employment contracts with each employee, afford them at least 28 days paid vacation period, limit the working week to 40 hours per week and follow the code’s specific procedures in case of employment termination.

EMPLOYEES

As of February 14, 2021, CBLI and its consolidated subsidiaries had 6 employees, 3 of whom are located in the U.S. and 3 of whom are located outside of the U.S. Of these employees, 2 were employed on a full-time basis and 4 were employed on a part-time basis.

ENVIRONMENT

We have made, and will continue to make, expenditures for environmental compliance and protection. Expenditures for compliance with environmental laws and regulations have not had, and are not expected to have, a material effect on our capital expenditures, results of operations, or competitive position.

Item 1A. Risk Factors

Risk Factors Summary

The following is a summary of the principal risks that could adversely affect our business, operations and financial results:

Risks Relating to our Financial Position and Need for Additional Financing

We will require substantial additional financing in order to meet our business objectives.

Since our inception, most of our resources have been dedicated to preclinical and clinical research and development ("R&D") of our product candidates. In particular, we are currently developing several product candidates, each of which will require substantial funds to complete. We believe that we will continue to expend substantial resources for the foreseeable future in the development of these product candidates. These expenditures will include costs associated with preclinical and clinical R&D, obtaining regulatory approvals, product manufacturing, corporate administration, business development, and marketing and selling for approved products. In addition, other unanticipated costs may arise. As of December 31, 2020, our cash, cash equivalents, and short-term investments amounted to $2.3 million.

Because the outcome and timing of our planned and anticipated clinical trials is highly uncertain, we cannot reasonably estimate the actual amounts of capital necessary to successfully complete the development and commercialization of our product candidates. Our future capital requirements depend on many factors, including:

When our available cash and cash equivalents become insufficient to satisfy our liquidity requirements, or if and when we identify additional opportunities to do so, we will likely seek to sell additional equity or debt securities or obtain additional credit facilities. The sale of additional equity or convertible debt securities may result in additional dilution to our stockholders. If we raise additional funds through the issuance of debt securities or preferred stock or through additional credit facilities, these securities and/or the loans under credit facilities could provide for rights senior to those of our common stockholders and could contain covenants that would restrict our operations. Furthermore, any funds raised through collaboration and licensing arrangements with third parties may require us to relinquish valuable rights to our technologies or product candidates, or grant licenses on terms that are not favorable to us. In any such event, our business prospects, financial condition and results of operations could be materially, adversely affected.

We may require additional capital beyond our currently forecasted amounts and additional funds may not be available when we need them, on terms that are acceptable to us, or at all. In addition, the recent outbreak of the novel coronavirus known as COVID-19 has significantly disrupted world financial markets, negatively impacted US market conditions and may reduce opportunities for us to seek out additional funding. In particular, a decline in the market price of our common stock could make it more difficult for us to sell equity or equity-related securities in the future at a time and price that we deem appropriate. If we fail to raise sufficient additional financing, on terms and dates acceptable to us, we may not be able to continue our operations and the development of our product candidates, our patent licenses may be terminated, and we may be required to reduce staff, reduce or eliminate research and development, slow the development of our product candidates, outsource or eliminate several business functions or shut down operations.

We expect to continue to incur losses.

We have incurred significant losses to date. We reported net losses of approximately $2.4 million and $2.7 million for the years ended December 31, 2020 and 2019, respectively. We expect significant losses to continue for the next few years as we spend substantial sums on the continued R&D of our proprietary product candidates, and there is no certainty that we will ever become profitable as a result of these expenditures. As a result of losses that will continue throughout our development stage, we may exhaust our financial resources and be unable to complete the development of our product candidates.

Our ability to become profitable depends primarily on the following factors:

Even if we successfully develop and market our product candidates, we may not generate sufficient or sustainable revenue to achieve or sustain profitability.

Our ability to use our net operating loss carryforwards may be limited.

As of December 31, 2020, we had federal net operating loss carryforwards ("NOLs") of $148.0 million to offset future taxable income, of which $139.7 million begins to expire if not utilized by 2023, and $8.3 million, which has no expiration. We also had approximately $4.3 million of federal tax credit carryforwards which begin to expire if not utilized by 2024. The Company also has U.S. state net operating loss carryforwards of approximately $93.8 million, which begin to expire if not utilized by 2027 and state tax credit carryforwards of approximately $0.3 million, which begin to expire if not utilized by 2022. 

The July 2015 purchase of 6,459,948 shares of common stock by David Davidovich, currently our largest stockholder, yielded a post-transaction ownership percentage of 60.2% for him. We believe it highly likely that this transaction will be viewed by the U.S. Internal Revenue Service as a change of ownership as defined by Section 382 of the Internal Revenue Code ("Section 382"). Consequently, the utilization of the NOL and tax credit carryforwards in existence at July 9, 2015, will be limited according to the provisions of Section 382, which could significantly limit the Company’s ability to use these carryforwards to offset taxable income on an annual basis in future periods. As such, a significant portion of these carryforwards could expire before they can be utilized, even if the Company is able to generate taxable income that, except for this transaction, would have been sufficient to fully utilize these carry forwards.

Risks Related to the Merger with Cytocom

The exchange ratio will not be adjusted based on the market price of our common stock so the merger consideration at the closing may have a greater or lesser value than at the time the Merger Agreement was signed.

At the effective time of the Merger, outstanding shares of Cytocom capital stock will be converted into shares of the Company’s common stock. Applying the exchange ratio, the former Cytocom securityholders immediately before the Merger are expected to own approximately 61% of the aggregate number of shares of the combined company’s common stock following the Merger on a fully diluted basis and our securityholders immediately before the Merger are expected to own approximately 39% of the aggregate number of shares of the combined company’s common stock following the Merger on a fully diluted basis. Certain adjustments to the exchange ratio will be made in respect of net cash, as determined in the Merger Agreement. Any changes in the market price of our stock before the completion of the Merger will not affect the number of shares Cytocom stockholders will be entitled to receive pursuant to the Merger Agreement. Therefore, if before the completion of the Merger, the market price of our common stock increases from the market price on the date of the Merger Agreement, then Cytocom stockholders could receive merger consideration with substantially more value for their shares of Cytocom capital stock than the parties had negotiated when they established the exchange ratio. Similarly, if before the completion of the Merger the market price of our common stock declines from the market price on the date of the Merger Agreement, then Cytocom stockholders could receive merger consideration with substantially lower value. The Merger Agreement does not include a price-based termination right.

Failure to complete the Merger may result in either the Company paying a termination fee and/or expense reimbursement amounts to Cytocom, which could harm the  price of our common stock and/or our future business and operations.

If the Merger is not completed, the Company is subject to the following risks:

If the Merger Agreement is terminated and the board of directors of the Company determines to seek another business combination, there can be no assurance that the Company will be able to find a partner with whom a business combination would yield greater benefits than the benefits to be provided under the Merger Agreement.

If the conditions to the Merger are not satisfied or waived, the Merger may not occur.

Even if the Merger is approved by the stockholders of Cytocom, specified conditions must be satisfied or waived to complete the Merger. These conditions are set forth in the Merger Agreement. The Company cannot assure you that all of the conditions to the consummation of the Merger will be satisfied or waived. If the conditions are not satisfied or waived, the Merger may not occur or the closing may be delayed, and the Company may lose some or all of the intended benefits of the Merger.

The Merger may be completed even though a material adverse effect may result from the announcement of the Merger, industry-wide changes or other causes.

In general, neither we nor Cytocom is obligated to complete the Merger if there is a material adverse effect affecting the other party between October 16, 2020, the date of the Merger Agreement, and the closing of the Merger. However, certain types of changes are excluded from the concept of a "material adverse effect." Such exclusions include but are not limited to changes in general economic or political conditions, industry wide changes, changes resulting from the announcement of the Merger, natural disasters, pandemics (including the COVID-19 pandemic), other public health events and changes in GAAP. Therefore, if any of these events were to occur impacting the Company or Cytocom, the other party would still be obliged to consummate the closing of the Merger. If any such adverse changes occur and the Company and Cytocom consummate the closing of the Merger, the stock price of the combined company may suffer. This in turn may reduce the value of the Merger to the stockholders of the Company.

Our stockholders may not realize a benefit from the Merger commensurate with the ownership dilution they will experience in connection with the Merger.

If the combined company is unable to realize the full strategic and financial benefits currently anticipated from the Merger, our stockholders will have experienced substantial dilution of their ownership interests without receiving any commensurate benefit, or only receiving part of the commensurate benefit to the extent the combined company is able to realize only part of the strategic and financial benefits currently anticipated from the Merger.

If the Merger is not completed, the price of our common stock may decline significantly.

The market price of our common stock is subject to significant fluctuations. Market prices for securities of pharmaceutical, biotechnology and other life science companies have historically been particularly volatile. In addition, the market price of our common stock will likely be volatile based on whether stockholders and other investors believe that the Company can complete the Merger or otherwise raise additional capital to support our operations if the Merger is not consummated and another strategic transaction cannot be identified, negotiated and consummated in a timely manner, if at all. The volatility of the market price of our common stock is exacerbated by low trading volume. Additional factors that may cause the market price of our common stock to fluctuate include:

Moreover, the stock markets in general have experienced substantial volatility that has often been unrelated to the operating performance of individual companies. These broad market fluctuations may also adversely affect the trading price of our common stock. In the past, following periods of volatility in the market price of a company’s securities, stockholders have often instituted class action securities litigation against such companies.

Company and Cytocom securityholders will have a reduced ownership and voting interest in, and will exercise less influence over the management of, the combined company following the completion of the Merger as compared to their current ownership and voting interests in the respective companies.

After the completion of the Merger, the current stockholders of the Company and Cytocom will own a smaller percentage of the combined company than their ownership of their respective companies prior to the Merger. Immediately after the Merger, Company securityholders as of immediately prior to the Merger are expected to own approximately 39% of the outstanding shares of the combined company on a fully diluted basis and former Cytocom securityholders are expected to own approximately 61% of the outstanding shares of the combined company on a fully diluted basis. The Chief Executive Officer of Cytocom will serve as the Chief Executive Officer of the combined company following the completion of the Merger.

During the pendency of the Merger, the Company and Cytocom may not be able to enter into a business combination with another party on more favorable terms because of restrictions in the Merger Agreement, which could adversely affect their respective business prospects.

Covenants in the Merger Agreement impede the ability of the Company and Cytocom to make acquisitions during the pendency of the Merger, subject to specified exceptions. As a result, if the Merger is not completed, the parties may be at a disadvantage to their competitors during that period. In addition, while the Merger Agreement is in effect, each party is generally prohibited from soliciting, proposing, seeking or knowingly encouraging, facilitating or supporting any inquiries, indications of interest, proposals or offers that constitute or may reasonably be expected to lead to certain transactions involving a third party, including a merger, sale of assets or other business combination, subject to specified exceptions. Any such transactions could be favorable to such party’s stockholders, but the parties may be unable to pursue them.

Certain provisions of the Merger Agreement may discourage third parties from submitting competing proposals, including proposals that may be superior to the transactions contemplated by the Merger Agreement.

The terms of the Merger Agreement prohibit each of the Company and Cytocom from soliciting competing proposals or cooperating with persons making unsolicited takeover proposals, except in limited circumstances. In addition, if the Company terminates the Merger Agreement under specified circumstances, the Company may be required to pay Cytocom a termination fee of $300,000 and in some circumstances one party may be required to pay the other party such party’s expenses up to $200,000. This termination fee may discourage third parties from submitting competing proposals to the Company or its stockholders, and may cause our board of directors to be less inclined to recommend a competing proposal.

Because the lack of a public market for Cytocom’s capital stock makes it difficult to evaluate the fair market value of Cytocom’s capital stock, we may pay more than the fair market value of Cytocom’s capital stock and/or the stockholders of Cytocom may receive consideration in the Merger that is less than the fair market value of Cytocom’s capital stock.

The outstanding capital stock of Cytocom is privately held and is not traded in any public market. The lack of a public market makes it difficult to determine the fair market value of Cytocom’s capital stock. Because the percentage of our equity to be issued to Cytocom stockholders was determined based on negotiations between the parties, it is possible that the value of our common stock to be received by Cytocom stockholders will be less than the fair market value of Cytocom’s capital stock, or the Company may pay more than the aggregate fair market value for Cytocom’s capital stock.

Risks Related to Product Development

We may not be able to successfully and timely develop our products.

Our product candidates range from ones currently in the research stage to ones currently in the clinical stage of development and all require further testing to determine their technical and commercial viability. Our success will depend on our ability to achieve scientific, clinical, and technological advances and to translate such advances into reliable, commercially competitive products in a timely manner. In addition, the success of our subsidiaries and joint ventures will depend on their ability to meet developmental milestones in a timely manner or to fulfill certain other development requirements under contractual agreements, which are prerequisites to their receipt of additional funding from their non-controlling interest holders or the government agency funding their R&D efforts. Products that we may develop are not likely to be commercially available for some time. The proposed development schedules for our products may be affected by a variety of factors, including, among others, technological difficulties, proprietary technology of others, the government approval process, the availability of funds, disagreements with the financial partners in our subsidiaries or joint ventures, the effects of the ongoing coronavirus pandemic, including access to clinical trial sites both by patents and our clinical research organizations, and changes in government regulation, many of which will not be within our control. Any delay in the development, introduction or marketing of our products could result either in such products being marketed at a time when their cost and performance characteristics would not be competitive in the marketplace or in the shortening of their commercial lives. In light of the long-term nature of our projects and the unproven technology involved, we may not be able to successfully complete the development or marketing of any products.

We may fail to develop and commercialize some or all of our products successfully or in a timely manner because:

Our collaborative relationships with third parties could cause us to expend significant resources and incur substantial business risk with no assurance of financial return.

We anticipate substantial reliance upon strategic collaborations for marketing and commercialization of our product candidates and we may rely even more on strategic collaborations for R&D of our product candidates. Our business depends on our ability to sell drugs to both government agencies and to the general pharmaceutical market. Offering entolimod for its biodefense indication to government agencies may require us to develop new sales, marketing or distribution capabilities beyond those already existing in the Company and we may not be successful in selling entolimod for its biodefense indication in the U.S. or in foreign countries despite our efforts. Selling oncology drugs will require a more significant infrastructure. We plan to sell oncology drugs through strategic partnerships with pharmaceutical companies. If we are unable to establish or manage such strategic collaborations on terms favorable to us in the future, our revenue and drug development may be limited. To date, we have not entered into any strategic collaboration with a third-party capable of providing these services and we can make no guarantee that we will be able to enter into a strategic collaboration in the future. In addition, we have not yet marketed or sold any of our product candidates or entered into successful collaborations for these services in order to ultimately commercialize our product candidates. We also rely on third-party collaborations with our manufacturers. Manufacturers producing our product candidates must follow GMP regulations enforced by the FDA and foreign equivalents.

Establishing strategic collaborations is difficult and time-consuming. Our discussion with potential collaborators may not lead to the establishment of collaborations on favorable terms, if at all. Potential collaborators may reject collaborations based upon their assessment of our financial, regulatory, or intellectual property position. Even if we successfully establish new collaborations, these relationships may never result in the successful development or commercialization of our product candidates or the generation of sales revenue. In addition, to the extent that we enter into collaborative arrangements, our drug revenues are likely to be lower than if we directly marketed and sold any drugs that we may develop.

We will not be able to commercialize our product candidates if our preclinical development efforts are not successful, our clinical trials do not demonstrate safety or our clinical trials or pivotal animal studies do not demonstrate efficacy.

Before obtaining required regulatory approvals for the commercial sale of any of our product candidates, we must conduct extensive preclinical and clinical studies to demonstrate that our product candidates are safe and clinical or pivotal animal trials to demonstrate that our product candidates are efficacious. And for entolimod's biodefense indication we must demonstrate a logical dosing correlation between animals and humans. These R&D activities are expensive, difficult to design and implement, can take many years to complete and are uncertain as to outcome. Success in preclinical testing and early clinical trials does not ensure that later clinical trials or animal efficacy studies will be successful and interim results of a clinical trial or animal efficacy study do not necessarily predict final results. In addition, we will likely have to continue to outsource all or part of individual R&D activities and may not successfully or promptly finalize agreements for the conduct of these activities. Consequently, delays in completion of contracted activities may result.

Engagement of contract research organizations ("CROs"), study investigators, and other third parties for clinical or animal testing or data management services, for example, transfers substantial responsibilities to these parties. As such we are dependent on these parties to timely execute their contracted work in a quality manner that complies with relevant standards and regulations such as GLPs. Failure of these parties to deliver timely and quality services could result in delays in, or termination of, contracted R&D activities. For example, if any of our clinical trial sites fail to comply with GCPs or our pivotal animal studies fail to comply with GLP regulations we may be unable to use the data generated. Consequently, if contracted CROs or other third parties do not properly execute their duties or fail to meet expected deadlines, our research activities may be extended, delayed or terminated, and we may be unable to obtain regulatory approval for or successfully commercialize our product candidates.

Our pivotal nonclinical and clinical trial operations are subject to regulatory inspections at any time. If regulatory inspectors conclude that we or our trial sites are not in compliance with applicable regulatory requirements for conducting such trials, we or they may receive warning letters or other correspondence detailing deficiencies and we will be required to implement corrective actions. If regulatory agencies deem our responses to be inadequate, or are dissatisfied with the corrective actions that we or our clinical trial sites have implemented, our clinical trials may be temporarily or permanently discontinued, we may be fined, we or our investigators may be the subject of an enforcement action, the government may refuse to approve our marketing applications or allow us to manufacture or market our products or we may be criminally prosecuted.

In addition, a failure of one or more of our clinical trials or animal studies can occur at any stage of testing and such failure could have a material adverse effect on our ability to generate revenue and could require us to reduce the scope of or discontinue our operations. We may experience numerous unforeseen events during, or as a result of, preclinical testing and the clinical trial or animal study process that could delay or prevent our ability to receive regulatory approval or commercialize our product candidates, including:

Even if we or our collaborators complete our animal studies and clinical trials and receive regulatory approval, it is possible that a product may be found to be ineffective or unsafe due to conditions or facts that arise after development has been completed and regulatory approvals have been obtained. In this event, we may be required to withdraw such product from the market. To the extent that our success will depend on any regulatory approvals from government authorities outside of the U.S. that perform roles similar to that of the FDA, uncertainties similar to those stated above will also exist.

Panacela and GPI have significant non-controlling interest holders and, as such, each may not be operated solely for our benefit.

As of December 31, 2020, we owned 67.57% of the equity interests in Panacela and 50% of the equity interests in GPI. Rusnano, a fund regulated by the Russian government, is a significant shareholder, along with other minority shareholders, in Panacela. Everon, a Buffalo, New York-based biopharmaceutical company, holds the other 50% of the equity interest in GPI. Additionally, as a result of its investment in GPI, Norma was granted a number of governance and other rights with respect to GPI. As such, we share ownership and management of Panacela and GPI with other parties who may not have the same goals, strategies, priorities or resources as we do.

With respect to Panacela, both we and Rusnano have certain rights, including the right to designate board members and the need for either supermajority votes or consent of all members of Panacela’s board of directors in order to take certain actions. Additionally, the right to transfer ownership is restricted by rights of first refusal, tag-along and drag-along rights. Consequently, if a co-owner sells its equity interest to a new party, the new party may adversely affect the operation of Panacela. These restrictions lead to organizational formalities that may be time-consuming. In addition, the benefits from a successful product development effort are shared among the co-owners.

With respect to GPI, under the terms of Norma’s investment, upon the occurrence of a number of different events, Norma has the right to require GPI to issue to Norma a number of shares in GPI, thereby further diluting our interest. Additionally, the Company, Everon, GPI and Norma each made certain commitments as to voting and transfer of their shares of GPI and GPI’s governance, including an agreement that the board of directors of GPI will consist of four members, two of whom will be selected by Norma, one of whom will be selected by the Company and one of whom will be selected by Everon. GPI is also prohibited from taking a number of actions without the unanimous consent of all of the members of GPI’s board of directors, including, among other things, effecting a change of control transaction, terminating its operations, dissolving or liquidating, amending its organizational documents, transferring or licensing its intellectual property, or issuing any shares of capital stock.

If parties on whom we rely to manufacture our product candidates do not manufacture them in satisfactory quality, in a timely manner, in sufficient quantities, or at an acceptable cost, clinical development and commercialization of our product candidates could be delayed.

We do not own or operate manufacturing facilities. Consequently, we rely on third parties as sole suppliers of our product candidates. We do not expect to establish our own manufacturing facilities and we will continue to rely on third-party manufacturers to produce supplies for preclinical, clinical, and pivotal animal studies and for commercial quantities of any products or product candidates that we market or may supply to our collaborators. We also rely on third parties as sole providers of certain testing of our products. Our dependence on third parties for the manufacture and testing of our product candidates may adversely affect our ability to develop and commercialize any product candidates on a timely and competitive basis.

To date, our product candidates have only been manufactured in quantities sufficient for preclinical studies and initial clinical trials. We rely on a single contract organization, Wacker Biotech B.V., for production of each of our product candidates. For a variety of reasons, dependence on any single manufacturer may adversely affect our ability to develop and commercialize our product candidates in a timely and competitive manner. In addition, our current contractual arrangements alone may not be sufficient to guarantee that we will be able to procure the needed supplies as we complete clinical development and/or enter commercialization.

Additionally, in connection with our application for commercial approvals and if any product candidate is approved by the FDA or other regulatory agencies for commercial sale, we will need to procure commercial quantities of the product candidate from qualified third-party manufacturers. We may not be able to contract for increased manufacturing capacity for any of our product candidates in a timely or economic manner or at all. A significant scale-up in manufacturing may require additional validation studies and commensurate financial investments by the contract manufacturers. If we are unable to successfully increase the manufacturing capacity for a product candidate, the regulatory approval or commercial launch of that product candidate may be delayed or there may be a shortage of supply, which could limit our sales and could initiate regulatory intervention to minimize public health risk.

Other risks associated with our reliance on contract manufacturers include the following:

Changes to the manufacturing process during the conduct of clinical trials or after marketing approval also require regulatory submissions and the demonstration to the FDA or other regulatory authorities that the product manufactured under the new conditions complies with GMPs requirements. These requirements especially apply to moving manufacturing functions to another facility. In each phase of investigation, sufficient information about changes in the manufacturing process must be submitted to the regulatory authorities and may require prior approval before implementation with the potential of substantial delay or the inability to implement the requested changes.

Risks Relating to Regulatory Approval

We may not be able to obtain regulatory approval in a timely manner or at all and the results of future clinical trials and pivotal efficacy studies may not be favorable.

The testing, marketing, and manufacturing of any product for use in the U.S. and the E.U. will require approval from the FDA and the EMA, respectively. We cannot predict with any certainty the amount of time necessary to obtain FDA approval and whether any such approval will ultimately be granted. Obtaining approval for products requires manufacturing the product and testing in animals and human subjects of substances whose effects on humans are not fully understood or documented. The manufacturing processes for our product candidates are not yet fully developed and identifying a reproducible process may prove difficult. Additionally, preclinical studies, animal efficacy studies, or clinical trials may reveal that one or more products are ineffective or unsafe, in which event, further development of such products could be seriously delayed, terminated or rendered more expensive.

In addition, we expect to rely on the FDA Animal Rule to obtain approval for entolimod’s biodefense indication in the U.S. The Animal Rule permits the use of animal efficacy studies together with human clinical safety trials to support an application for marketing approval of products when human efficacy studies are neither ethical nor feasible. These regulations have limited prior use and we have limited experience in the application of these rules to the product candidates that we are developing. Additionally, we submitted an application with the FDA for pre-EUA in 2015 so that entolimod may be used in an emergency situation. We cannot guarantee that the FDA will review the data submitted in a timely manner, or that the FDA will accept the data when reviewed. The FDA may decide that our data are insufficient for pre-EUA or BLA approval and require additional preclinical, clinical, or other studies, refuse to approve our products, or place restrictions on our ability to commercialize those products. The FDA has previously requested additional data and studies with respect to our pre-EUA application for entolimod (as a result of which the FDA has placed our clinical protocol on clinical hold), and the FDA may do so again in the future. If we are not successful in completing the development, licensure, and commercialization of entolimod for its biodefense indication, or if we are significantly delayed in doing so, our business will be materially harmed.

Delays in obtaining FDA, EMA, or any other necessary regulatory approvals of any proposed product or the failure to receive such approvals would have an adverse effect on our ability to develop such product, the product’s potential commercial success and/or on our business, prospects, financial condition and results of operations.

Failure to obtain regulatory approval in international jurisdictions could prevent us from marketing our products abroad.

We intend to market our product candidates, including specifically the product candidates being developed by our Russian subsidiaries, in the U.S., Europe, Russia, and other countries and regulatory jurisdictions. In order to market our product candidates in the U.S., Europe, Russia, and other jurisdictions, we must obtain separate regulatory approvals in each of these countries and territories. The procedures and requirements for obtaining marketing approval vary among countries and regulatory jurisdictions and may involve additional clinical trials or other tests. In addition, we do not have in-house experience and expertise regarding the procedures and requirements to file for and obtain marketing approval for drugs in countries outside of the U.S., Europe, and Japan and may need to engage and rely upon expertise of third parties when we file for marketing approval in countries outside of the U.S., Europe, and Japan. Also, the time required to obtain approval in markets outside of the U.S. may differ from that required to obtain FDA approval, while still including all of the risks associated with obtaining FDA approval. We may not be able to obtain all of the desirable or necessary regulatory approvals on a timely basis, if at all. Approval by a regulatory authority in a particular country or regulatory jurisdiction, such as the FDA in the U.S. or the EMA in the E.U., does not ensure approval by a regulatory authority in another country.

We may not be able to file for regulatory approvals and may not receive necessary approvals to commercialize our product candidates in any or all of the countries or regulatory jurisdictions in which we desire to market our product candidates. At this time, to our knowledge, other countries do not have an equivalent to the Animal Rule and, as a result, such countries do not likely have established criteria for review and approval for this type of product outside their normal review process. Specifically, because such other countries do not have an equivalent to the Animal Rule, we may not be able to file for or receive regulatory approvals for entolimod’s biodefense indication outside the U.S. based on our animal efficacy and human safety data.

The Fast Track designation for entolimod may not actually lead to a faster development or regulatory review or approval process.

We have obtained a "Fast Track" designation from the FDA for entolimod’s biodefense indication. However, we may not experience a faster development process, review, or approval compared to conventional FDA procedures. The FDA may withdraw our Fast Track designation if the FDA believes that the designation is no longer supported by data from our clinical or pivotal development program. Our Fast Track designation does not guarantee that we will qualify for or be able to take advantage of the FDA’s expedited review procedures or that any application that we may submit to the FDA for regulatory approval will be accepted for filing or ultimately approved.

The pre-EUA submission we made to the FDA in 2015 may not be successful and, even if such submission is successful, it may not accelerate BLA approval of entolimod or result in any purchase by the U.S. government for this product.

In July 2014, we met with the FDA regarding human dose-conversion of entolimod and based on the results of that meeting, we submitted a pre-EUA dossier in the second quarter of 2015 in order to inform and expedite the FDA’s issuance of an EUA, should one become necessary in the event of an emergency. The FDA does not have review deadlines with respect to pre-EUA submissions and, therefore, the timing of any approval of a pre-EUA submission is uncertain.

The FDA may decide not to accept the data or may decide that our data are insufficient for pre-EUA. The FDA may require additional Chemistry, Manufacturing, and Controls ("CMC"), preclinical, clinical or other studies, refuse to approve our products, or place restrictions on our ability to commercialize those products. For example, in 2016, the FDA asked the Company to establish the comparability of an older formulation of entolimod that had been used for preclinical and clinical studies and a newer to-be-marked formulation. The FDA requested that we perform a side-by-side analytical comparability study and then an in vivo study in NHP to establish bio-comparability between the two entolimod drug formulations. The FDA agreed last year that the Company had documented analytical comparability and bio-comparability in NHP and agreed to continue the review of the pre-EUA dossier by the Agency. There can be no guarantee that the FDA will not request any additional information related to our preclinical, clinical or manufacturing programs. Additionally, an authorization of our pre-EUA submission will not guarantee, and may not accelerate, BLA approval of entolimod as a radiation countermeasure.

Further, even if our pre-EUA submission is authorized, there is no guarantee that such authorization will lead to procurement by the U.S. or other governments or any additional development funding as it is possible that the U.S. or other government may not be interested in our product or our proposed terms of sale for any number of reasons including, but not limited to, lack of available funding, potential lack of government co-sponsorship of our pre-EUA, perceptions about the safety and effectiveness of entolimod, the storage requirements for entolimod or one of our competitors receiving pre-EUA authorization for their product. If we are not successful in partnering entolimod or completing the development, licensure and commercialization of entolimod for its biodefense indication use, or if we are significantly delayed in doing so, our business may be materially harmed.

Even if our drug candidates obtain regulatory approval, we will be subject to ongoing government regulation.

Even if our drug candidates obtain regulatory approval, our products will be subject to continuing regulation by international health authorities, including record-keeping requirements, submitting periodic reports, reporting of any adverse experiences with the product and complying with Risk Evaluation and Mitigation Strategies and drug sampling and distribution requirements. In addition, updated safety and efficacy information must be maintained and provided to the authorities. We or our collaborative partners, if any, must comply with requirements concerning advertising and promotional labeling, including the prohibition against promoting non-approved or "off-label" indications or products. Failure to comply with these requirements could result in significant enforcement action by the international health authorities, including warning letters, orders to pull the promotional materials and substantial fines.

After the approval of a product, the discovery of problems with a product or its class, or the failure to comply with requirements may result in restrictions on a product, manufacturer or holder of an approved marketing application. These include withdrawal or recall of the product from the market or other voluntary or regulatory agency-initiated action that could delay or prevent further marketing. Newly discovered or developed safety or effectiveness data, including from other products in a therapeutic class, may require changes to a product’s approved labeling, including the addition of new warnings and contraindications. Also, the FDA and other international health authorities are likely to require post-market clinical testing of products approved under the Animal Rule or similar regulations at the time of a declared emergency and may require post-market clinical testing of other products. They may also require surveillance to monitor the product’s safety or efficacy to evaluate long-term effects. It is also possible that rare but serious adverse events not seen in our drug candidates may be identified after marketing approval. This could result in withdrawal of our product from the market.

Compliance with post-marketing regulations may be time-consuming and costly and could delay or prevent us from generating revenue from the commercialization of our drug candidates.

If physicians and patients do not accept and use our drugs, we will not achieve sufficient product revenues and our business will suffer.

Even if we gain marketing approval of our drug candidates, government purchasers, physicians and/or patients may not accept and use them. Acceptance and use of these products may depend on a number of factors including:

The failure of our drugs, if approved for marketing, to gain acceptance in the market would harm our business and could require us to seek additional financing.

Risks Related to our Dependence on U.S. and Foreign Government Contracts and Grants

If we are unable to procure additional government funding, we may not be able to fund future R&D and implement technological improvements, which would materially harm our financial condition and operating results.

In September 2015, we announced the grant of two awards from DoD, totaling approximately $15.8 million for advanced development of entolimod as a medical radiation countermeasure. These awards, the contracts for which have been amended since the initial grants to approximately $3.8 million earlier this year, were earned as the contracted development work was performed over a multi-year period. For the years ended December 31, 2020 and 2019, we received 81.2%, and 64.5% of our revenues from the U.S. government. The contracts with the DoD providing for these awards have expired.

These revenues have funded some of our operating costs and expenses. However, we will continue to incur substantial additional costs to fund our operations for which we may apply for other sources of government funding. If we do submit proposals for new grants or contracts, the review of such proposals and ultimate funding of an award may take significant time. Contract and grant awards are subject to a significant amount of uncertainty, including, but not limited to, successful negotiation and availability of funds. In addition, in our experience, contracts from Russian government entities require matching funds and posting of performance guarantees. Therefore, we expect that our acceptance of new contracts or grants from Russian government entities will also be subject to our ability to provide matching funds and to post performance guarantees.

If we are unable to obtain sufficient grants and contracts on a timely basis, our ability to fund future operations would be diminished, which would negatively impact our ability to compete in our industry and could materially and adversely affect our business, financial condition and operating results.

Our future business may be harmed as a result of the foreign and U.S. government contracting process as it involves risks not present in the commercial marketplace.

We expect that a significant portion of the business that we will seek in the near future will be under government contracts or subcontracts, both U.S. and foreign, which may be awarded through competitive bidding. For example, as described above, since 2015, we have received funding from DoD to support further development of entolimod. Additionally, in Russia we may seek additional funding from the Skolkovo Foundation or the Russian Federation Ministry of Industry and Trade (the "MPT"). Competitive bidding for government contracts presents a number of risks that are not typically present in the commercial contracting process, which may include:

The U.S. government may choose to award future contracts for the supply of medical radiation countermeasures to our competitors instead of to us. If we are unable to win particular contracts, or if the government chooses not to fully exercise all options under contracts awarded to us, we may not be able to operate in the market for products that are provided under those contracts for a number of years. If we are unable to consistently win new contract awards, or if we fail to anticipate all of the costs and resources that will be required to secure such contract awards, our growth strategy and our business, financial condition and operating results could be materially adversely affected.

Additionally, government authorities have a high degree of discretion in Russia and have at times exercised their discretion selectively or arbitrarily, without hearing or prior notice, and sometimes in a manner that is perceived to be influenced, or may be influenced, by political or commercial considerations. The government also has the power, in certain circumstances, to interfere with the performance of, nullify or terminate contracts.

The market for U.S. and other government funding is highly competitive.

We periodically submit applications for funding of various research studies of our product candidates to the U.S. and other governments. There is no guarantee that any proposals that we plan to submit will be funded even if we receive positive reviews of such proposals as funding by the government is highly competitive and limited to the availability of funds. Failure to receive funding from U.S. and other government sources for the development of our product candidates could impair our ability to fund the development programs for our product candidates and thus could result in delays in development, or even stopping of development, of certain indications for our product candidates.

Notably, our biodefense product candidate, entolimod, faces significant competition for U.S. government funding for both development and procurement of medical countermeasures for biological, chemical and nuclear threats, diagnostic testing systems and other emergency preparedness countermeasures. In addition, we may not be able to compete effectively if entolimod does not satisfy procurement requirements of the U.S. government with respect to biodefense products. Our opportunities to succeed in the biodefense industry could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer side effects, are more convenient or are less expensive than any products that we may develop.

U.S. government agencies have special contracting requirements, which create additional risks.

We have historically entered into contracts with various U.S. government agencies. Due to these contracts with government agencies, we are subject to various federal contract requirements. Future sales to U.S. government agencies will depend, in part, on our ability to meet these requirements, certain of which we may not be able to satisfy.

U.S. government contracts typically contain unfavorable termination provisions and are subject to audit by the government at its sole discretion even after the end of the period of performance under the contract, which subjects us to additional risks. These risks include the ability of the U.S. government to unilaterally:

Pursuant to our government contracts, we are generally permitted to retain title to any patentable invention or discovery made while performing the contract. However, the U.S. government is generally entitled to receive a non-exclusive, non-transferable, irrevocable, paid-up license to the subject inventions throughout the world. In addition, our government contracts generally provide that the U.S. government retains unlimited rights in the technical data produced under such government contract.

Our business could be adversely affected by a negative audit by the U.S. government.

As a U.S. government contractor, we may become subject to periodic audits and reviews by U.S. government agencies such as the Defense Contract Audit Agency ("DCAA"). These agencies review a contractor’s performance under its contracts, cost structure and compliance with applicable laws, regulations and standards. The DCAA also reviews the adequacy of, and a contractor’s compliance with, its internal control systems and policies, including the contractor’s accounting, purchasing, property, estimating, compensation and management information systems. Any costs found to be improperly allocated to a specific contract will not be reimbursed and, such costs already reimbursed must be refunded.

Based on the results of these audits, the U.S. government may adjust our contract-related costs and fees, which have already been paid to us, including allocated indirect costs. In addition, if an audit or review uncovers any improper or illegal activity, we may be subject to civil and criminal penalties and administrative sanctions, including termination of our contracts, forfeiture of profits, suspension of payments, fines and suspension or prohibition from doing business with the U.S. government. We could also suffer serious harm to our reputation if allegations of impropriety were made against us. In addition, under U.S. government purchasing regulations, some of our costs, including most financing costs, amortization of intangible assets, portions of our R&D costs, and some marketing expenses, may not be reimbursable or allowed under our contracts. Further, as a U.S. government contractor, we may become subject to an increased risk of investigations, criminal prosecution, civil fraud, whistleblower lawsuits, and other legal actions and liabilities to which purely private sector companies are not.

Risks Relating to our Intellectual Property

We rely upon licensed patents to protect our technology. We may be unable to obtain or protect such intellectual property rights and we may be liable for infringing upon the intellectual property rights of others.

Our ability to compete effectively will depend on our ability to maintain the proprietary nature of our technologies and the proprietary technology of others with which we have entered into licensing agreements. We have entered into five separate exclusive license agreements to license from third parties our product candidates that are not owned by us and some product candidates are covered by up to three separate license agreements. Pursuant to these license agreements we maintain patents and patent applications covering our product candidates. We do not know whether any of these patent applications that are still in the approval process will ultimately result in the issuance of a patent with respect to the technology owned by us or licensed to us. The patent position of pharmaceutical or biotechnology companies, including ours, is generally uncertain and involves complex legal and factual considerations. The standards that the United States Patent and Trademark Office use to grant patents are not always applied predictably or uniformly and can change. There is also no uniform, worldwide policy regarding the subject matter and scope of claims granted or allowable in pharmaceutical or biotechnology patents. Accordingly, we do not know the degree of future protection for our proprietary rights or the breadth of claims that will be allowed in any patents issued to us or to others.

Our technology may be found in the future to infringe upon the rights of others or be infringed upon by others. In such a case, others may assert infringement claims against us, and should we be found to infringe upon their patents, or otherwise impermissibly utilize their intellectual property, we might be forced to pay damages, potentially including treble damages, if we are found to have willfully infringed on such parties’ patent rights. Furthermore, parties making claims against us may be able to obtain injunctive or other equitable relief which could effectively block our ability to further develop, commercialize and sell products. In addition to any damages we might have to pay, we may be required to obtain licenses from the holders of this intellectual property, enter into royalty agreements, or redesign our products so as not to utilize this intellectual property, each of which may prove to be uneconomical or otherwise impossible. Conversely, we may not always be able to successfully pursue our claims against others that infringe upon our technology and the technology exclusively licensed by us or developed with our collaborative partners. Thus, the proprietary nature of our technology or technology licensed by us may not provide adequate protection against competitors.

Moreover, the cost to us of any litigation or other proceeding relating to our patents and other intellectual property rights, even if resolved in our favor, could be substantial and the litigation would divert our management’s efforts and our resources. Uncertainties resulting from the initiation and continuation of any litigation could limit our ability to continue our operations.

If we fail to comply with our obligations under our license agreement with third parties, we could lose our ability to develop our product candidates.

The manufacture and sale of any products developed by us may involve the use of processes, products or information, the rights to certain of which are owned by others. Although we have obtained exclusive licenses for our product candidates from The Cleveland Clinic and RPCI with regard to the use of patent applications as described above and certain processes, products and information of others, these licenses could be terminated or expire during critical periods and we may not be able to obtain licenses for other rights that may be important to us, or, if obtained, such licenses may not be obtained on commercially reasonable terms. Furthermore, some of our product candidates require the use of technology licensed from multiple third parties, each of which is necessary for the development of such product candidates. If we are unable to maintain and/or obtain licenses, we may have to develop alternatives to avoid infringing upon the patents of others, potentially causing increased costs and delays in product development and introduction or precluding the development, manufacture, or sale of planned products. Additionally, the patents underlying any licenses may not be valid and enforceable. To the extent any products developed by us are based on licensed technology, royalty payments on the licenses will reduce our gross profit from such product sales and may render the sales of such products uneconomical.

Our current exclusive licenses impose various development, royalty, diligence, record keeping, insurance, solvency and other obligations on us. If we breach any of these obligations and do not cure such breaches within the relevant cure period, the licensor may have the right to terminate the license, which could result in us being unable to develop, manufacture and sell products that are covered by the licensed technology or enable a competitor to gain access to the licensed technology.

In addition, while we cannot currently determine the dollar amount of the royalty and other payments we will be required to make in the future under the license agreements, if any, the amounts may be significant. The dollar amount of our future payment obligations will depend on the technology and intellectual property we use in products that we successfully develop and commercialize, if any.

If we are not able to protect and control our unpatented trade secrets, know-how and other technology, we may suffer competitive harm.

We also rely on a combination of trade secrets, know-how, technology and nondisclosure and other contractual agreements and technical measures to protect our rights in the technology. However, trade secrets are difficult to protect and we rely on third parties to develop our products and thus must share trade secrets with them. We seek to protect our proprietary technology in part by entering into confidentiality agreements and, if applicable, material transfer agreements, collaborative research agreements, consulting agreements or other similar agreements with our collaborators, advisors, employees, and consultants prior to beginning research or disclosing proprietary information. These agreements will typically restrict the ability of our collaborators, advisors, employees, and consultants to publish data potentially relating to our trade secrets. Our academic collaborators typically have rights to publish data, provided that we are notified in advance and may delay publication for a specified time in order to secure our intellectual property rights arising from the collaboration. Despite our efforts to protect our trade secrets, our competitors may discover our trade secrets, either through breach of these agreements, independent development or publication of information including our trade secrets in cases where we do not have proprietary or otherwise protected rights at the time of publication. If any trade secret, know-how or other technology not protected by a patent or intellectual property right were disclosed to, or independently developed by, a competitor, our business, financial condition and results of operations could be materially adversely affected.

Risks Relating to our Industry and Other External Factors

The biopharmaceutical market in which we compete is highly competitive.

The biopharmaceutical industry is characterized by rapid and significant technological change. Our success will depend on our ability to develop and apply our technologies in the design and development of our product candidates and to establish and maintain a market for our product candidates. In addition, there are many companies, both public and private, including major pharmaceutical and chemical companies, specialized biotechnology firms, universities and other research institutions engaged in developing pharmaceutical and biotechnology products. Many of these companies have substantially greater financial, technical, research and development resources, and human resources than us. Competitors may develop products or other technologies that are more effective than those that are being developed by us or may obtain FDA or other governmental approvals for products more rapidly than us. If we commence commercial sales of products, we still must compete in the manufacturing and marketing of such products, areas in which we have no experience.

The COVID-19 pandemic could adversely impact our business, operations and clinical development timelines and plans.

In December 2019, a novel strain of coronavirus, COVID-19, was reported to have surfaced in Wuhan, China. Since then, COVID-19 has spread to multiple countries, including the United States, where a national emergency was declared, and several European countries. If COVID-19 continues to spread in the United States and worldwide, we may experience disruptions that could severely impact our business, operations, preclinical studies and clinical trials, including:

Additionally, on March 20, 2020, the Governor of New York announced that 100% of the workforce of all businesses, excluding essential services, must stay home. During the effectiveness of this order , we implemented a work-from-home policy for all employees based in our Buffalo, New York headquarters. Under new applicable state orders, our offices may be occupied at 50% of their normal capacity if other safety precautions are taken, however, generally very few of our employees have returned to the office. 

The global outbreak of COVID-19 continues to rapidly evolve and has begun to have indeterminable adverse effects on general commercial activity and the world economy. The extent to which COVID-19 may impact our business, research and development efforts, preclinical studies, clinical trials, prospects for regulatory approval of our drug candidates, and operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the outbreak, the pace and effectiveness of vaccination efforts, the extent and duration of travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease. In addition, a recession or market correction resulting from the spread of COVID-19 could materially affect our business prospects and the value of our common stock.  Furthermore, if we or any of the third parties with whom we engage were to experience or re-experience shutdowns or other business disruptions, our ability to conduct our business in the manner and on the timelines presently planned could be materially and negatively impacted, which could have a material adverse effect on our business, financial condition and results of operations.

Our growth could be limited if we are unable to attract and retain key personnel and consultants.

Our success depends, in large part, on our ability to identify, hire, integrate, retain, and motivate qualified executive officers and other key employees throughout all areas of our business. We greatly depend on the efforts of our executive officers to manage our operations. However, we currently do not employ a permanent chief executive officer or chief financial officer. Our board of directors is currently undertaking a search for permanent replacement officers.  While we have designated our Vice President of Finance as our interim principal executive officer and principal financial officer, our lack of a permanent chief executive officer and chief financial officer may materially and adversely affect our business prospects and investor confidence in our Company, which could cause the trading price of our common stock to decline. In addition, we utilize highly skilled personnel in operating and supporting our business, as we have limited experience in filing and prosecuting regulatory applications to obtain marketing approval from the FDA or other regulatory authorities. The loss of services of one or more members of our management, key employees or consultants could have a negative impact on our business or our ability to expand our research, development and clinical programs. Furthermore, we may be unable to attract and retain additional qualified executive officers and key employees as needed in the future. We currently do not maintain directors and officers liability insurance, which may make it more difficult for us to retain and attract talented and skilled directors and officers to serve our Company.

Additionally, we depend on our scientific, manufacturing, regulatory clinical collaborators and advisors, all of whom have outside commitments that may limit their availability to us. Furthermore, to the extent that we are unable to engage certain collaborators or advisors for certain periods of time due to lack of relevant work or lack of available funds, there is a risk that such collaborators or advisors will not be available to provide services in the future at such time when there is available work and/or funds. In addition, we believe that our future success will depend in large part upon our ability to attract and retain highly skilled scientific, managerial and marketing personnel, particularly as we expand our activities in clinical trials, the regulatory approval process, external partner solicitations and sales and manufacturing. We routinely enter into consulting agreements with our scientific, manufacturing, business development, regulatory, clinical collaborators, advisors, and opinion leaders in the ordinary course of our business. We also enter into contractual agreements with physicians and institutions who recruit patients into our clinical trials on our behalf in the ordinary course of our business. We face significant competition for this type of personnel and for employees from other companies, research and academic institutions, government entities and other organizations. We cannot predict our success in hiring or retaining the personnel we require for continued growth.

We may be subject to damages resulting from claims that we, our employees or our consultants have wrongfully used or disclosed alleged trade secrets of their former employers.

We engage as employees and consultants individuals who were previously employed at other biotechnology or pharmaceutical companies, including at competitors or potential competitors. Although no claims against us are currently pending, we may become subject to claims that we or our employees have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and distract management.

We may incur substantial liabilities from any product liability and other claims if our insurance coverage for those claims is inadequate.

We face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical trials and will face an even greater risk if the product candidates are sold commercially. An individual may bring a product liability claim against us if one of the product candidates causes, or merely appears to have caused, an injury. If we cannot successfully defend ourselves against the product liability claim, we will incur substantial liabilities. Regardless of merit or eventual outcome, product liability claims may result in:

We currently have product liability insurance and intend to expand such coverage from coverage for clinical trials to include the sale of commercial products if marketing approval is obtained for any of our product candidates. However, insurance coverage is increasingly expensive. We may not be able to maintain insurance coverage that will be adequate to satisfy any liability that may arise.

From time to time, we may also become subject to litigation, such as stockholder derivative claims or securities fraud claims, including as a result of our pending merger with Cytocom, which could involve our directors and officers as defendants. We currently do not have director and officer insurance to cover such risk exposure for our directors and officers. Our certificate of incorporation and bylaws require us to indemnify our current and past directors and officers from reasonable expenses related to the defense of any action arising from their service to us to the fullest extent permitted by the Delaware General Corporation Law, including circumstances under which indemnification is otherwise discretionary. We would be obligated to cover all such expenses for all directors and officers, which may be substantial. Such expenditure could have a material adverse effect on our results of operation, financial condition and liquidity.

Our former laboratories used, and our subtenants use, certain chemical and biological agents and compounds that may be deemed hazardous and we are subject to various safety and environmental laws and regulations. Our compliance with these laws and regulations may result in significant costs, which could materially reduce our ability to become profitable.

Until late 2013, we operated laboratories that used hazardous materials, including chemicals and biological agents and compounds that could be dangerous to human health and safety or the environment and we currently sublease these laboratories for operation by other companies, which currently use hazardous materials. As appropriate, we stored these materials and wastes resulting from their use at our laboratory facility pending their ultimate use or disposal and we currently require that our laboratory sub-lessors do the same. We contracted with a third party to properly dispose of these materials and wastes and our laboratory sub-lessors now manage such contracts. We were and continue to be subject to a variety of federal, state and local laws and regulations governing the use, generation, manufacture, storage, handling and disposal of these materials and wastes. We may incur significant costs if we unknowingly failed to comply with environmental laws and regulations.

We rely significantly on information technology and any failure, inadequacy, interruption or security lapse of that technology, including any cybersecurity incidents, could harm our ability to operate our business effectively.

Despite the implementation of security measures, our internal computer systems and those of third parties with which we contract are vulnerable to damage from cyber-attacks, computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. System failures, accidents or security breaches could cause interruptions in our operations, and could result in a material disruption of our product development and clinical activities and business operations, in addition to possibly requiring substantial expenditures of resources to remedy. The loss of product development or clinical trial data could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and our development programs and the development of our product candidates could be delayed.

Political or social factors may delay or impair our ability to market our products.

Entolimod is being developed to treat ARS, which is a disease that may be caused by terrorist acts. The political and social responses to terrorism have been highly charged and unpredictable. Political or social pressures may delay or cause resistance to bringing our products to market or limit pricing of our products, which would harm our business. Changes to favorable laws, such as the Project BioShield Act, could have a material adverse effect on our ability to generate revenue and could require us to reduce the scope of or discontinue our operations.

We announced in September 2015 that we received two awards from the DoD for the further development of entolimod. We hope to receive additional funding in the future from U.S. or foreign government agencies for the development of entolimod and our other products. Changes in government budgets and agendas, however, have previously resulted in termination of our contract negotiations and may, in the future, result in future funding being decreased and de-prioritized. In addition, government contracts contain provisions that permit cancellation in the event that funds are unavailable to the government agency. Furthermore, we cannot be certain of the timing of any future funding and substantial delays or cancellations of funding could result from protests or challenges from third parties. If the U.S. government fails to continue to adequately fund R&D programs, we may be unable to generate sufficient revenues to continue development of entolimod or continue our other operation. Similarly, if our pre-EUA submission for entolimod is authorized by the FDA, but the U.S. government does not place sufficient orders for this product, our future business may be harmed.

Failure to comply with the U.S. Foreign Corrupt Practices Act and similar foreign laws could subject us to penalties and other adverse consequences.

We are required to comply with the U.S. Foreign Corrupt Practices Act ("FCPA"), which prohibits U.S. companies from engaging in bribery or other prohibited payments to foreign officials for the purpose of obtaining or retaining business. Foreign companies, including some that may compete with us, are not subject to these prohibitions. Furthermore, foreign jurisdictions in which we operate may have laws that are similar to the FCPA to which we are or may become subject. This may place us at a significant competitive disadvantage. Corruption, extortion, bribery, pay-offs, theft, and other fraudulent practices may occur from time to time in the foreign markets where we conduct business. Although we inform our personnel that such practices are illegal, we can make no assurance that our employees or other agents will not engage in illegal conduct for which we might be held responsible. If our employees or other agents are found to have engaged in such practices, we could suffer severe penalties and other consequences that may have a material adverse effect on our business, financial condition and results of operations.

The FCPA also obligates companies whose securities are listed in the U.S. to comply with certain accounting provisions requiring the Company to maintain books and records that accurately and fairly reflect all transactions of the corporation, including international subsidiaries and to devise and maintain an adequate system of internal accounting controls for international operations.

Compliance with the FCPA and similar foreign anti-bribery laws is expensive and difficult, particularly in countries in which corruption is a recognized problem. In addition, such anti-bribery laws present particular challenges in the biotech or pharmaceutical industry, because, in many countries, hospitals are operated by the government and doctors and other hospital employees may be considered foreign officials.

Risks Related to Conducting Business in Russia

Political, economic and governmental instability in Russia could materially adversely affect our operations and financial results.

Panacela Labs, LLC, which is the wholly-owned subsidiary of Panacela, conducts business, including clinical trials, in Russia through Russian legal entities. Also, Rusnano is a Russian joint-stock company created as a private equity and venture capital vehicle by the government of Russia. Panacela Labs, LLC owns the worldwide rights to Mobilan. Rusnano has certain shareholder rights which could block our ability to execute strategic transactions such as an asset sale or licensing arrangement. All clinical development activity conducted by these Russian entities was funded by grants from MPT. As such, any political, economic, or governmental instability in Russia could impact future funding, if any, by MPT, our access to trial data and our access to intellectual property for out-licensing purposes.

In addition to geopolitical events, other factors, including the steady fall in oil prices, the global strengthening of the U.S. dollar and the Russian Central Bank’s reduction of currency rate support, have negatively affected the value of the Russian ruble relative to the U.S. dollar. Fluctuations in the rates at which the U.S. dollar is exchanged into Russian rubles may result in both foreign currency transaction and translation losses. We are subject to exchange rate fluctuations if we or one of our subsidiaries exchanges one currency into another, in order to conduct cross-border operations, and as we translate ruble denominated assets and liabilities that fluctuate from period-to-period. The former results in a transaction gain/loss that is reflected in our operating results. The latter results in a translation gain/loss reflected in other comprehensive income/loss in equity. Additionally, translation of historical operating results at average exchange rates for respective periods of time will also generate foreign currency translation adjustments that are reflected in our operating results. Presently, Panacela conducts most of its activities in Russia. As such we expect most of the foreign currency fluctuations to be related to accounting translations, versus transaction gains and losses.

Even before the current events mentioned above, and since the early 1990s, Russia has sought to transform from a one-party state with a centrally planned economy to a democracy with a market economy. As a result of the sweeping nature of various reforms and the failure of some of them, the political system of Russia remains vulnerable to popular dissatisfaction, including demands for autonomy from particular regional and ethnic groups. Current and future changes in the Russian government, major policy shifts or lack of consensus between various branches of the government and powerful economic groups could disrupt or reverse economic and regulatory reforms. Furthermore, the Russian economy is vulnerable to market downturns and economic slowdowns elsewhere in the world, and has experienced periods of considerable instability. Although the Russian economy showed positive trends until 2008, including annual increases in the gross domestic product, a relatively stable currency, strong domestic demand, rising real wages and a reduced rate of inflation, these trends were interrupted by the global financial crisis in late 2008, in which Russia experienced adverse economic and financial effects including a substantial decrease in the growth rate of gross domestic product, depreciation of local currency and a decline in domestic and international demand for its products and services. Economic instability in Russia could materially adversely affect our business, financial condition and results of operations.

The current geopolitical instability arising from U.S relations with Russia, and related sanctions by the U.S. government against certain Russian companies and individuals, may have an adverse effect on us.

Political and economic relations between Russia and the U.S., two of the jurisdictions in which we operate, are complex. Recent situations involving Ukraine, Crimea, Iran, Syria, and alleged cyberespionage by the Russian government against the U.S. Democratic National Committee and in connection with the 2016 U.S. presidential election, the cyberespionage effort effected through SolarWinds Inc. that has been alleged to have been perpetrated by Russian state actors, along with the response of the governments of Russia, the U.S., member states of the E.U., the E.U. itself and other nations, have the potential to materially adversely affect our operations in Russia through a variety of situations. In particular, due to Russia’s recent military intervention in Ukraine, the United States, Canada and the E.U. have imposed sanctions against Russian officials, certain Russian companies and individuals. These sanctions were designed to affect various elements of Russia’s economy, with a particular focus on defense companies, individuals identified by the U.S. Department of State as being in the "inner circle" of the current Russian president, banks and energy companies. Russia has responded with certain countermeasures, including limiting the import of certain goods from the U.S. and other countries.

There can be no assurance that such sanctions will not be expanded more broadly to impact a greater variety of actors in the Russian economy. If the U.S. government significantly broadens the scope of sanctions against Russia to impose further political and economic costs, and/or the Russian government responds with further countersanctions, the operation of our direct and indirect Russian subsidiary Panacela Labs, LLC, which performs clinical development work under grants received from the MPT and have development or other intellectual property rights to certain of our drug candidates, may be materially and adversely affected. Furthermore, because the largest holder of our company’s outstanding common stock is an investor with ties to Russia, and several Russian citizens and residents serve on our board of directors, our ability to secure and maintain contracts with the U.S. Department of Defense and other U.S. government agencies or departments, from which we received 81.2% and 64.5% of our revenues for the years ended December 31, 2020 and 2019, respectively, may become more difficult, which could cause a material adverse impact on our business, prospects, results of operation, and financial condition.

Emerging markets, such as Russia, are subject to greater risks than more developed markets and financial turmoil in Russia could disrupt our business.

Investors in emerging markets, such as Russia, should be aware that these markets are subject to greater risks than more developed markets, including significant economic risks. For example, the Russian economy has periodically experienced high rates of inflation. According to The World Bank, the annual inflation rate in Russia, as measured by the consumer price index, was 7.1% in 2016, 3.7% in 2017, 2.9% in 2018, 4.47 in 2019, and 3.22% in 2020. Periods of higher inflation may slow economic growth. Inflation also is likely to increase some of our costs and expenses including the costs for our Russian subsidiary to conduct business operations, including any outsourced product testing costs.

Prospective investors in our common stock should note that emerging markets are subject to rapid change and that the information set forth in our filings with the SEC about our operations in Russia may become outdated relatively quickly.

The legal system in Russia can create an uncertain environment for business activity, which could materially adversely affect our business and operations in Russia.

The legal framework in Russia is still under development and large portions of this framework have only recently become operational. The relatively recent enactment of many laws and the lack of consensus about the aims, scope, content, and pace of economic and political reforms have resulted in ambiguities, inconsistencies, and anomalies in the Russian legal system. The enforceability and underlying constitutionality of more recently enacted laws are in doubt, and many new laws remain untested.

As a result, its legal system can be characterized by: inconsistencies between and among laws and governmental, ministerial, and local regulations, orders, decisions, resolutions, and other acts; gaps in the regulatory structure resulting from the delay in adoption or absence of implementing regulations; selective enforcement of laws or regulations, sometimes in ways that have been perceived as being motivated by political or financial considerations; limited judicial and administrative guidance on interpreting legislation; relatively limited experience of judges and courts in interpreting recent commercial legislation; a perceived lack of judicial and prosecutorial independence from political, social and commercial forces; inadequate court system resources; a high degree of discretion on the part of the judiciary and governmental authorities; and underdeveloped bankruptcy procedures that are subject to abuse.

In addition, as is true of civil law systems generally, judicial precedents generally have no binding effect on subsequent decisions. Not all legislation and court decisions in Russia are readily available to the public or organized in a manner that facilitates understanding. Enforcement of court orders can in practice be very difficult. All of these factors make judicial decisions difficult to predict and effective redress uncertain. Additionally, court claims and governmental prosecutions may be used in furtherance of what some perceive to be political or commercial aims.

The untested nature of much of recent legislation in Russia and the rapid evolution of its legal system may result in ambiguities, inconsistencies, and anomalies in the application and interpretation of laws and regulations. Any of these factors may affect our ability to enforce our rights under our contracts or to defend ourselves against claims by others, or result in our being subject to unpredictable requirements. These uncertainties also extend to property rights and the expropriation or nationalization of any of our entities, their assets or portions thereof, potentially without adequate compensation, could materially adversely affect our business, financial condition and results of operations.

Judgments rendered by a court in any jurisdiction outside Russia are likely to be recognized by courts in Russia only if: (i) an international treaty providing for the recognition and enforcement of judgments in civil cases exists between Russia and the country where the judgment is rendered; and/or (ii) a federal law of Russia providing for the recognition and enforcement of foreign court judgments is adopted. No such federal law has been passed and no such treaty exists between the United States and Russia for the reciprocal enforcement of foreign courts’ judgments. In the absence of an applicable treaty or convention providing for the recognition and enforcement of judgments in civil and commercial matters between the United States and Russia, a judgment of a U.S. court may be recognized and enforced in Russia only on the grounds of reciprocity. In each case, reciprocity must be established and, in the absence of a developed court practice, it is difficult to predict whether a Russian court will be inclined to recognize and enforce a U.S. court judgment on the grounds of reciprocity in any particular instance.

Actions by the tax authorities in Russia may result in the sudden imposition of arbitrary or onerous taxes on our operations in Russia.

BioLab 612 and Panacela Labs, LLC’s tax liabilities are subject to periodic tax inspections that may result in tax assessments, penalties and interest being claimed from such subsidiaries for prior tax periods. Generally, tax declarations of Russian subsidiaries remain open and subject to audit by tax and/or customs authorities for three calendar years immediately preceding the year in which the decision to conduct an audit is taken. However, the fact that a particular year has been reviewed by tax authorities does not preclude that year from further review or audit during the eligible three-year limitation period by a superior tax authority. Moreover, the Russian tax authorities are allowed to carry out repeat field tax audits in connection with the restructuring or liquidation of a taxpayer or if the taxpayer resubmits an adjusted tax return based on which the amount of tax is reduced. The limitation of the tax audit period corresponds to the statute of limitations on the commission of a tax offense, which is also limited to three years from the date on which a tax offense was committed or from the date following the end of the tax period during which the tax offense was committed depending on the nature of the tax offense. The Russian Tax Code provides for the extension of the three-year statute of limitations if the actions of the taxpayer created insurmountable obstacles for the tax audit.

As none of the relevant terms are defined, tax authorities may have broad discretion to argue that a taxpayer has "obstructed", "hindered," or "created insurmountable obstacles" with respect to an inspection and may ultimately seek to review and possibly to apply penalties beyond the three-year term. Further, there is no guarantee that the tax authorities will not review compliance with applicable tax law beyond the three-year limitation period. Tax audits may result in additional costs if the relevant authorities conclude that the BioLab 612, Panacela Labs, LLC, or both did not satisfy their tax obligations in any given year. The outcome of these audits may result in significant fines, penalties and enforcement measures which may have a material adverse effect on our business, financial condition, results of operations, and prospects.

The tax system in Russia imposes additional burdens and costs on our operations there and complicates our tax planning and related business decisions. For example, the tax environment in Russia has historically been complicated by contradictions in Russian tax law and ambiguity in areas such as the deductibility of certain expenses. This uncertainty could result in a greater than expected tax burden and potentially exposes us to significant fines and penalties and enforcement measures, despite our best efforts at compliance. These factors raise the risk of a sudden imposition of arbitrary or onerous taxes on our operations in Russia. This could materially adversely affect our financial condition and results of operations.

Selective or arbitrary government action may have an adverse effect on our business.

Government authorities have a high degree of discretion in Russia and have at times exercised their discretion selectively or arbitrarily, without hearing or prior notice, and sometimes in a manner that is perceived to be influenced, or may be influenced, by political or commercial considerations. The government also has the power, in certain circumstances, to interfere with the performance of, nullify, or terminate contracts. Selective or arbitrary actions have included withdrawal of licenses, sudden and unexpected tax audits, criminal prosecutions and civil actions. Federal and local government entities have also used common defects in documentation as pretexts for court claims and other demands to invalidate and/or to void transactions, apparently for political purposes. We cannot assure you that regulators, judicial authorities or third parties will not challenge our compliance with applicable laws, decrees and regulations in Russia. Selective or arbitrary government action could have a material adverse effect on our business and on the value of our common stock.

Shareholder liability under Russian legislation could cause us to become liable for the obligations of our subsidiaries.

Under Russian law, we may become liable for the obligations of our Russian subsidiaries if it was determined that: (i) we had the ability to make, or exert influence on, decisions for such subsidiaries as a result of our equity interest, the terms of a binding contract with such Russian subsidiary or in any other way; and (ii) the relevant Russian subsidiary concluded the transaction giving rise to the obligations pursuant to the Company's instructions or consent. In addition, we may have secondary liability for the obligations of our Russian subsidiaries in a situation where the respective Russian subsidiary becomes insolvent or bankrupt and this was a result of, or was otherwise attributable to, actions of the Company. This type of liability could result in significant losses, and could have a material adverse effect on the Company’s business, results of operations or financial position.

Accordingly, in the Company’s position as a parent of Russian subsidiaries, there is a risk that it could be held liable in certain limited circumstances for the debts of its effective subsidiaries. If this liability is significant, it could materially adversely affect our business, financial condition or our results of operations.

Our Russian operating entities can be forced into liquidation on the basis of formal noncompliance with certain legal requirements.

Panacela Labs, LLC was organized under the laws of Russia. Certain provisions of Russian law may allow a court to order the liquidation of a locally organized legal entity on the basis of its formal noncompliance with certain requirements during formation, reorganization, or during its operations. Additionally, Russian corporate law allows the government to liquidate a company if its net assets fall below a certain threshold. Similarly, there have also been cases in Russia in which formal deficiencies in the establishment process of a legal entity or noncompliance with provisions of law have been used by courts as a basis for liquidation of a legal entity. Weaknesses in the legal systems of Russia create an uncertain legal environment, which makes the decisions of a court or a governmental authority difficult, if not impossible, to predict. If involuntary liquidation of Panacela Labs, LLC were to occur, such liquidation could materially adversely affect our financial condition and results of operations.

Crime and corruption could disrupt our ability to conduct our business.

Political and economic changes in Russia in recent years have resulted in significant dislocations of authority. The local and international press has reported the existence of significant organized criminal activity, particularly in large metropolitan centers. In addition, the local and international press has reported high levels of corruption, including the bribing of officials for the purpose of initiating investigations by government agencies. Press reports have also described instances in which state officials have engaged in selective investigations and prosecutions to further the interests of the state and individual officials, as well as private businesses, including competitors and corporate raiders. Corruption in Russia is perceived to be pervasive and, in some cases, worsening. The government in Russia has recently pursued a campaign against corruption. However, there is no assurance that such laws or other laws enacted elsewhere will be applied with any effectiveness by the local authorities and the continuing effects of corruption, money laundering and other criminal activity could have a negative effect on the Russian economy and could materially adversely affect our business in Russia.

Risks Relating to our Securities 

Our largest stockholder has the ability to control our business, which may be disadvantageous to other stockholders.

As of the date of this filing, Mr. David Davidovich, a venture capital investor, beneficially owns or controls approximately 48.3% of the voting power of our outstanding common stock. As a result of his being the single largest holder of the voting power of our outstanding common stock, Mr. Davidovich has the ability to substantially control all matters requiring approval by our stockholders, including the election and removal of directors, amendments to our certificate of incorporation and bylaws, any proposed merger, consolidation or sale of all or substantially all of our assets and other corporate transactions. Mr. Davidovich may have interests that are different from those of other stockholders and may vote in a way with which other stockholders disagree and that may be adverse to other stockholders’ interests. Moreover, this concentration of share ownership makes it extremely difficult for other stockholders to replace directors and management without the consent of Mr. Davidovich. In addition, this significant concentration of share ownership may adversely affect the price prospective buyers are willing to pay for our common stock because investors may perceive disadvantages in owning stock in companies with controlling stockholders and may have the effect of delaying, preventing, or deterring a change of control of the Company and could deprive our stockholders of an opportunity to receive a premium for their company stock as part of a sale of the Company. Additionally, our corporate structure, including the ownership of Mobilan in Panacela, and the licensing of certain of entolimod’s indications to GPI, may deter third parties from entering into collaboration and licensing arrangements with us.

The price of our common stock has been and could remain volatile, which may in turn expose us to securities litigation.

The market price of our common stock has historically experienced and may continue to experience significant volatility. From January 1, 2019 through December 31, 2020, the market price of our common stock, which is listed on the NASDAQ Capital Market, fluctuated from a high of $4.26 per share in the second quarter of 2020 to a low of $0.51 in the fourth quarter of 2019. The listing of our common stock on the NASDAQ Capital Market does not assure that a meaningful, consistent, and liquid trading market will exist, and in recent years, the market has experienced extreme price and volume fluctuations that have particularly affected the market prices of many smaller companies like us. Our common stock is thus subject to this volatility in addition to volatility caused by the occurrence of industry and company specific events. Factors that could cause fluctuations include, but are not limited to, the following:

In addition, the stock market in general, and the stock price of companies listed on the NASDAQ, and biotechnology companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the market price of our common stock, regardless of actual operating performance.

As a result of the volatility of our stock price, we could be subject to securities litigation, which could result in substantial costs and divert management’s attention and company resources from our business.

Issuance of additional equity may adversely affect the market price of our stock.

We are currently authorized to issue 25,000,000 shares of common stock and 1,000,000 shares of preferred stock. As of this filing, 15,469,055 shares of our common stock were issued and outstanding, we had outstanding warrants to purchase 299,519 shares of our common stock at an average exercise price of $5.62 per share, and options to purchase 76,064 shares of our common stock at an average exercise price of $27.35 per share. To the extent we issue shares of common stock or our outstanding options and warrants are exercised, holders of our common stock will experience dilution.

In the event of any other future issuances of equity securities or securities convertible into or exchangeable for, common stock, holders of our common stock may experience dilution. Furthermore, certain of our outstanding warrants contain provisions that, in certain circumstances, could result in the number of shares of common stock issuable upon the exercise of such securities to increase and/or the exercise price of such warrants to decrease.

Moreover, our board of directors is authorized to issue preferred stock without any action on the part of our stockholders. Our board of directors also has the power, without stockholder approval, to set the terms of any such preferred stock that may be issued, including voting rights, conversion rights, dividend rights, preferences over our common stock with respect to dividends or if we liquidate, dissolve, or wind up our business and other terms. If we issue shares of preferred stock in the future that have preference over our common stock with respect to the payment of dividends or upon our liquidation, dissolution or winding up, or if we issue preferred stock with voting rights that dilute the voting power of our common stock, the market price of our common stock could decrease. Additionally, the conversion of any preferred stock issued in the future into our common stock could result in significant dilution to the holders of our common stock.

The eventual public resale by certain of our significant stockholders could have a negative effect on the trading price of our common stock.

In July 2015, we issued an aggregate of 6,716,163 shares of our Company’s common stock to Mr. Davidovich and Rusnano. The issuances of these shares were not registered under the Securities Act of 1933, and the shares are only able to be resold pursuant to a separate registration statement or an applicable exemption from registration (under both federal and state securities laws). Contractual restrictions prohibiting Mr. Davidovich from selling his shares have expired and pursuant to the terms of registration rights agreements entered into between the Company and each of Mr. Davidovich and Rusnano, we have filed a registration statement on Form S-3 with the SEC to register the public offer and resale of the shares held by these stockholders. The registration statement has been declared effective by the SEC and Mr. Davidovich and Rusnano are each able to freely sell some or all of their shares of our Company’s common stock. If all or a substantial portion of these shares are resold into the public markets under such registration statement or otherwise, such transactions may cause a decline in the trading price of our common stock.

We do not intend to pay dividends for the foreseeable future.

We do not intend to declare or pay any cash dividends in the foreseeable future. We anticipate that we will retain all of our future earnings for use in the development of our business and for general corporate purposes. Any determination to pay dividends in the future will be at the discretion of our board of directors. Accordingly, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments.

We also consider from time to time various strategic alternatives that could involve issuances of additional shares of common stock or shares of preferred stock, including but not limited to acquisitions and business combinations.

If securities or industry analysts do not publish research or reports about our business, or publish negative reports about our business, our stock price and trading volume could decline.

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these reports and we currently do not have any industry analysts covering us. In the event we do regain analyst coverage, there can be no assurance that analysts will provide favorable coverage. Our stock price may be adversely impacted by our current lack of analyst coverage as we may have less visibility in the financial markets than other companies in our industry, which may cause declined trading volume and stock price.

We have, in the past, failed to satisfy certain continued listing requirements of the Nasdaq Capital Market and could fail to satisfy those requirements again in the future, which could affect the market price of our common stock and liquidity and reduce our ability to raise capital.

Currently, our common stock trades on the Nasdaq Capital Market.  During 2019 and 2020, we received notification from Nasdaq informing us of certain listing deficiencies related to the minimum required stockholders’ equity and minimum bid price listing requirements, which led to the issuance of delisting notices. Although we have since cured these deficiencies and our common stock continues to trade on the Nasdaq Capital Market, it is possible that we could fall out of compliance again in the future. If we fail to maintain compliance with any Nasdaq listing requirements, our common stock could be delisted from the Nasdaq Capital Market. This could severely limit the liquidity of our common stock and your ability to sell our securities on the secondary market.

Our operations could be disrupted by natural or human causes beyond our control.

Our operations are subject to the risk of disruption by hurricanes, severe storms, floods and other forms of severe weather, earthquakes and other natural disasters, accidents, fire, power shortages, geopolitical unrest, war and other military action, terrorist attacks and other hostile acts, public health issues, epidemics or pandemics (including, for example, the recent novel coronavirus outbreak), and other events, such as raw material or supply scarcity, that are beyond our control and the control of the third parties on which we depend. Any of these catastrophic events, whether in the United States or abroad, may have a strong negative impact on the global economy, our employees, facilities, suppliers, or potential customers and could materially adversely affect our business, financial condition or results of operations.

Item 1B. Unresolved Staff Comments

None.

Item 2. Description of Properties

Our corporate headquarters is located at 73 High Street, Buffalo, New York 14203. This space serves as our corporate headquarters and U.S. corporate headquarters for Panacela. In addition, we have approximately 187 square feet under lease outside of the U.S. expiring at varying times through 2021. We do not own any real property.

Item 3. Legal Proceedings

In the ordinary course of business, we may periodically become subject to legal proceedings and claims arising in connection with ongoing business activities. The results of litigation and claims cannot be predicted with certainty, and unfavorable resolutions are possible and could materially affect our results of operations, cash flows, or financial position. In addition, regardless of the outcome, litigation could have an adverse impact on us because of defense costs, diversion of management resources and other factors.

While the outcome of these proceedings and claims cannot be predicted with certainty, other than as set forth below, there are no matters, that in the opinion of management might have a material adverse effect on our financial position, results of operations, or cash flows, or that are required to be disclosed under the rules of the SEC.

On March 12, 2021, a complaint, captioned Teo v. Cleveland BioLabs, Inc. et al., Case 1:21-cv-02187, was filed in the U.S. District Court for the Southern District of New York in connection with the Merger (the "Teo Action"). The Teo Action names as defendants the Company, each director on the Company’s board of directors and Cytocom. The complaint in the Teo Action alleges that (i) the Company’s board of directors breached its fiduciary duties to the plaintiff stockholder in entering into the Merger Agreement and (ii) the Company and the Company’s board of directors omitted and/or provided misleading information in the registration statement on Form S-4 filed with the SEC in connection with the Merger in violation of the Securities Exchange Act of 1934, as amended (the "Exchange Act") and related SEC regulations.  The Teo Action seeks, among other things, an injunction preventing the closing of the merger, rescission of the merger if it is consummated, damages and an award of plaintiffs’ attorneys’ and experts’ fees.

On March 18, 2021, a complaint, captioned Wang v. Cleveland BioLabs, Inc. et al., Case 1:21-cv-02395, was filed in the U.S. District Court for the Southern District of New York in connection with the Merger (the "Wang Action").  The Wang Action names as defendants the Company, each director on the Company’s board of directors and Cytocom.  The complaint in the Wang Action alleges that the Company and the Company’s board of directors omitted and/or provided misleading information in the registration statement on Form S-4 filed with the SEC in connection with the Merger in violation of the Exchange Act and related SEC regulations. The Wang Action seeks, among other things, an injunction preventing the closing of the merger, rescission of the merger if it is consummated, the dissemination by the Company of a revised registration statement on Form S-4 and an award of plaintiffs’ attorneys’ and experts’ fees.

The outcome of this lawsuits is uncertain. The Company believes that the claims asserted are without merit.

Item 4. Mine Safety Disclosure

None.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

STOCK EXCHANGE LISTING

Our common stock trades on The NASDAQ Capital Market under the symbol "CBLI." We have not paid dividends on our common stock. We currently intend to retain all future income for use in the operation of our business and for future stock repurchases and, therefore, we have no plans to pay cash dividends on our common stock at this time.

STOCKHOLDERS

As of February 8, 2021, there were approximately 24 stockholders of record of our common stock. Because many of our shares are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of beneficial stockholders represented by these record holders.

DIVIDENDS

We have never declared or paid any cash dividends on our capital stock. We currently intend to use the net proceeds from any offerings of our securities and our future earnings, if any, to finance the further development and expansion of our business and do not intend or expect to pay cash dividends in the foreseeable future. Payment of future cash dividends, if any, will be at the discretion of our board of directors after taking into account various factors, including our financial condition, operating results, current and anticipated cash needs, outstanding indebtedness, and plans for expansion and restrictions imposed by lenders, if any. Additionally, our merger agreement with Cytocom contains negative covenants that restrict us from, without Cytocom’s consent, declaring or paying any dividends or other distributions on our common stock until the closing of the merger with Cytocom.

UNREGISTERED SALE OF SECURITIES

Except as previously disclosed, we did not sell any equity securities during the fiscal year ended December 31, 2020 in transactions that were not registered under the Securities Act.

ISSUER PURCHASES OF EQUITY SECURITIES

We made no repurchases of our securities during the year ended December 31, 2020.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

OVERVIEW

We are an innovative biopharmaceutical company developing novel approaches to activate the immune system and address serious medical needs. Our proprietary platform of Toll-like immune receptor activators has applications in mitigation of radiation injury and radiation oncology. We combine our proven scientific expertise and our depth of knowledge about our products’ mechanisms of action into a passion for developing drugs to save lives. Our most advanced product candidate is entolimod, an immune-stimulatory agent, which we are developing as a radiation countermeasure and other indications in radiation oncology. We conduct business in the U.S. and Russia through two subsidiaries, one of which is wholly owned, BioLab 612, which was dissolved in November 2020; and one of which is owned in collaboration with a financial partner, Panacela. In addition, we conducted business with a former subsidiary, Incuron, which will pay us a 2% royalty on future commercialization, licensing, or sale of certain technology we sold to Incuron. We also partner in a joint venture, GPI, with Everon Biosciences, Inc. See Item 1, "Business" for more information on our product candidates and our strategic partnerships.

RECENT DEVELOPMENTS

Merger with Cytocom, Inc.

As previously disclosed, on October 16, 2020, the Company, Merger Sub, and Cytocom entered into the Merger Agreement, pursuant to which, among other matters, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Merger Sub will merge with and into Cytocom, with Cytocom continuing as a wholly owned subsidiary of the Company and the surviving corporation of the merger. Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger, each outstanding share of Cytocom common stock, each outstanding share of Cytocom preferred stock that was not, by its terms, converted into shares of Cytocom common stock immediately prior to the effective time of the merger, and each vested restricted stock unit of Cytocom will be converted into the right to receive a number of shares of the Company’s common stock determined by the application of an exchange formula set forth in the Merger Agreement. The exchange formula provides that the total number of shares of the Company’s common stock to be issued as merger consideration for the Cytocom’s capital stock will, upon issuance, be equal to approximately 61% of the outstanding shares of the combined company’s common stock. Accordingly, under the exchange ratio formula in the Merger Agreement, as of immediately after the Merger, the former Cytocom stockholders are expected to own approximately 61% of the outstanding shares of the combined company’s common stock on a fully diluted basis and stockholders of the Company as of immediately prior to the Merger are expected to own approximately 39% of the outstanding shares of the combined company’s common stock on a fully diluted basis. Certain adjustments to this ratio will be made in respect of each party’s net cash at the time of the closing of the Merger, as determined in accordance with the Merger Agreement. Each unvested Cytocom restricted stock unit award will be converted into a restricted stock unit award of the Company. Immediately following the effective time of the Merger, the board of directors of the Company will consist of seven members, three of whom will be designated by the Company and four of whom will be designated by Cytocom. In addition, upon the closing of the Merger, Cytocom’s Chief Executive Officer, Michael Handley, will serve as Chief Executive Officer of the combined company. The closing of the Merger is subject to the satisfaction or waiver of certain conditions including, among other things, (i) the required approvals by the Company’s stockholders, (ii) the accuracy of the respective representations and warranties of each party, subject to certain materiality qualifications, (iii) compliance by the parties with their respective covenants, (iv) the absence of any law or order preventing the Merger and related transactions, (v) the shares of the Company’s common stock to be issued in the Merger being approved for listing (subject to official notice of issuance) on Nasdaq as of the closing and (vi) a registration statement on Form S-4 having become effective in accordance with the provisions of the Securities Act of 1933, as amended, and not being subject to any stop order or proceeding (or threatened proceeding by the SEC) seeking a stop order with respect to such registration statement that has not been withdrawn.

COVID-19 Pandemic

The COVID-19 pandemic has continued to affect multiple countries, including the United States, where a national emergency was declared, and several European and Asian countries. The continued spread of COVID-19 in the United States and worldwide, as well as the government-ordered shutdown and shelter-in-place orders imposed to counter the pandemic, have led to severe disruptions to the global economy. In this connection, on March 20, 2020, the Governor of New York announced that 100% of the workforce of all businesses, excluding essential services, must stay home. During the effectiveness of this order, we implemented a work-from-home policy for all employees based in our Buffalo, New York headquarters. Under new applicable state orders, our offices may be occupied at 50% of their normal capacity if other safety precautions are taken, however, generally very few of our employees have returned to the office.  We are continuing to monitor the situation and will take such further action  as may be required by federal, state or local authorities, or that we determine are in the best interests of our employees. COVID-19 and the governmental responses to it may cause us to experience disruptions that could severely impact our business, operations, preclinical studies and clinical trials. The global outbreak of COVID-19 continues to rapidly evolve and has begun to have indeterminable adverse effects on general commercial activity and the world economy. The extent to which COVID-19 may impact our business, research and development efforts, preclinical studies, clinical trials, prospects for regulatory approval of our drug candidates, and operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the outbreak, the pace and effectiveness of vaccination efforts, the extent and duration of travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease. In addition, a recession or market correction resulting from the spread of COVID-19 could materially affect our business prospects and the value of our common stock.  Furthermore, if we or any of the third parties with whom we engage were to experience or re-experience shutdowns or other business disruptions, our ability to conduct our business in the manner and on the timelines presently planned could be materially and negatively impacted, which could have a material adverse effect on our business, financial condition and results of operations.

Registered Direct Offering

As previously disclosed, on February 19, 2021, the Company entered into a Securities Purchase Agreement (the "Purchase Agreement") with several healthcare-focused and institutional investors for the sale by the Company of 2,000,000 shares (the "Shares") of the Company’s common stock at a purchase price of $7.00 per share, in a registered direct offering. The closing of the sale of the Shares under the Purchase Agreement occurred on February 23, 2021. The gross proceeds to the Company from the transaction were approximately $14 million, before deducting the placement agent’s fees and other estimated offering expenses. The Shares were offered and sold by the Company under a prospectus supplement and accompanying prospectus filed with the SEC pursuant to an effective shelf registration statement on Form S-3, which was filed with the SEC on May 21, 2020 and subsequently declared effective on May 29, 2020 (File No. 333-238578). Under the Company’s engagement letter (the "Engagement Letter") with H.C. Wainwright & Co., LLC ("Wainwright"), pursuant to which Wainwright agreed to serve as exclusive placement agent for the issuance and sale of the Shares and Warrants, the Company agreed to pay Wainwright an aggregate fee equal to 7.25% of the gross proceeds received by the Company from the sale of the securities in the transaction as well as a management fee equal to 1.0% of the gross proceeds received by the Company from the sale of the securities in the transactions. Pursuant to the Engagement Letter, the Company also issued to designees of Wainwright warrants to purchase up to 7.5% of the aggregate number of shares of Common Stock sold in the transactions, or warrants to purchase up to 150,000 shares of Common Stock (the "Placement Agent Warrants"). Subject to certain ownership limitations, the Placement Agent Warrants are immediately exercisable at an exercise price of $8.75 per share of Common Stock, subject to customary adjustments as provided under the terms of the Placement Agent Warrants. The Warrants are exercisable for five years from the commencement of sales of the shares being offered.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. ("GAAP"). The preparation of these financial statements requires us to make estimates and judgments that affect our reported amounts of assets, liabilities, revenues, and expenses.

On an ongoing basis, we evaluate our estimates and judgments, including those related to accrued expenses, income taxes, stock-based compensation, investments, and in-process R&D. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the reported amounts of revenues and expenses that are not readily apparent from other sources. Actual results may differ from these estimates.

We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our financial statements.

Revenue Recognition

Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed and determinable, collectability is reasonably assured, contractual obligations have been satisfied and title and risk of loss have been transferred to the customer. We generate our revenue from two different types of contractual arrangements: (i) cost-reimbursement grants and contracts and (ii) fixed-price grants and contracts. Costs consist primarily of actual internal labor charges, subcontractor and material costs incurred, plus an allocation of fringe benefits, overhead and general and administrative expenses ("G&A"), and applicable fees, if any, based on the terms of the contract.

Revenues on cost-reimbursement grants and contracts are recognized in an amount equal to the costs incurred during the period, plus an estimate of the applicable fee earned. The estimate of the applicable fee earned is determined by reference to the contract; if the contract defines the fee in terms of risk-based milestones and specifies the fees to be earned upon the completion of each milestone, then the fee is recognized when the related milestones are earned. Otherwise, we compute fee income earned in a given period by using a proportional performance method based on costs incurred during the period as compared to total estimated project costs and application of the resulting fraction to the total project fee specified in the grant or contract.

Revenues on fixed-price grants and contracts are recognized using a percentage-of-completion method, which uses assumptions and estimates, as appropriate. These assumptions and estimates are developed in coordination with the principal investigator performing the work under the fixed-price grant or contract to determine levels of accomplishments throughout the life of the grant or contract.

Stock-Based Compensation

We expense all share-based awards to employees and consultants, including grants of stock options and shares, based on their estimated fair value at the date of grant. Costs of all share-based payments are recognized over the requisite service period that an employee or consultant must provide to earn the award (i.e., the vesting period) and allocated to the functional operating expense associated with that employee or consultant.

Fair Value of Financial Instruments

The carrying value of cash and cash equivalents, accounts receivable, short-term investments, accounts payable and accrued expenses approximates fair value due to the relatively short maturity of these instruments. Certain common stock warrants, which are classified as liabilities, are recorded at their fair market value as of each reporting period.

The measurement of fair value requires the use of techniques based on observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. The inputs create the following fair value hierarchy:

We use the Black-Scholes model to determine the fair value of certain common stock warrants on a recurring basis and classify such warrants in Level 3. The Black-Scholes model utilizes inputs consisting of: (i) the closing price of our common stock; (ii) the expected remaining life of the warrants; (iii) the expected volatility using historical volatilities of CBLI; and (iv) the risk-free market rate.

As of December 31, 2020, there was $0.00 million in accrued expenses relating to Level 3 securities for warrants to purchase common stock.

Income Taxes

Determining the consolidated provision for income tax expense, deferred tax assets and liabilities and related valuation allowance, if any, involves judgment. On an on-going basis, we evaluate whether a valuation allowance is needed to reduce our deferred income tax assets to an amount that is more likely than not to be realized. The evaluation process includes assessing historical and current results in addition to future expected results. Upon determining that we would be able to realize our deferred tax assets, an adjustment to the deferred tax valuation allowance would increase income in the period we make such determination.

Research and Development Expenses

Research and development ("R&D") costs are expensed as incurred. Advance payments are deferred and expensed as performance occurs. R&D costs include the cost of our personnel (which consists of salaries and incentive and stock-based compensation), out-of-pocket preclinical and clinical trial costs usually associated with contract research organizations, drug product manufacturing and formulation, and a pro-rata share of facilities expense and other overhead items.

General and Administrative Expenses

General and administrative ("G&A") functions include executive management, finance and administration, government affairs and regulations, corporate development, human resources, and legal and compliance. The specific costs include the cost of our personnel consisting of salaries, incentive and stock-based compensation, out-of-pocket costs usually associated with attorneys (both corporate and intellectual property), bankers, accountants and other advisors, and a pro-rata share of facilities expense and other overhead items.

Other Income and Expenses

Other recurring income and expenses primarily consists of interest income on our investments, changes in the market value of our derivative financial instruments, and foreign currency transaction gains or losses.

YEAR ENDED DECEMBER 31, 2020 COMPARED TO YEAR ENDED DECEMBER 31, 2019

Revenue

Revenue decreased from $1.1 million for the year ended December 31, 2019 to $0.3 million for the year ended December 31, 2020, representing a decrease of $0.8 million, or 76%, primarily due to a decrease in revenue from the JWMRP DoD contract and PRMRP DoD grant for preclinical studies, and the Incuron service contract for continued preclinical development. We do not anticipate any revenues from JWMRP or PRMRP in 2021 due to the completion of the contract and grant in 2020. Service revenue from Incuron is also expected to cease as our service contract was not extended.

Since these revenue sources are cost reimbursable in nature, variances in these activities, period to period, are directly aligned with variances in the underlying costs of service. Differences in our revenue sources, by program, between 2020 and 2019 are set forth in the following table:

The following table sets forth information regarding our recently completed grant contracts as of December 31, 2020:

Contract modifications with the DoD were entered into during the third quarter of 2020 that reduced the JWMRP and PRMRP funded awards from an aggregate of $15,800,447 to an aggregate of $3,773,463, as reflected in the table above. 

Research and Development Expenses

R&D expenses decreased from $1.7 million for the year ended December 31, 2019 to $0.7 million for the year ended December 31, 2020, representing a decrease of $1.0 million, or 58%. Variances in individual development programs are noted in the table below. Significant reductions include the $0.6 million reduction of funds spent on entolimod for biodefense indication due to reduced preclinical development activity resulting from our previously disclosed vendor delays in the analytical analyses required to complete the biocomparability study and the FDA having not agreed with the Company's conclusions regarding the biocomparability study until earlier this year, which has prevented further development progress from occurring, and a decrease of $0.3 million related to Curaxins. We anticipate that R&D expenses associated with the development of our drug candidates will increase in 2021 as we plan to address some FDA questions concerning our pre-EUA submission. However, should the FDA have additional questions regarding the pre-EUA submission, we could conduct additional significant unplanned studies as necessary to respond to the FDA questions, within the confines of current funding limitations.

General and Administrative Expenses

G&A expenses increased from $1.8 million for the year ended December 31, 2019 to $2.2 million for the year ended December 31, 2020, representing an increase of $0.4 million, or 19%. This increase consisted primarily of a $0.5 million increase in professional fees associated with activities related to the potential Cytocom merger and the filing of the Company's Form S-3 Registration Statement, a $0.15 million increase in other costs for cash awards to certain members of the Company's board of directors, and a $0.08 million increase in CBLI's property taxes compared 2019 when we received a property tax refund, partially offset by a $0.4 million decrease in personnel and consulting costs.

Other Income and Expenses

Other income and expense changed from $0.3 million of other expense for the year ended December 31, 2019 to $0.1 million of other income for the year ended December 31, 2020, representing an income increase of $0.4 million, or 145%. This increase was related to a $0.9 million increase in other income resulting from the 2020 reversal of an approximate $0.5 million revenue loss contingency recorded in 2019, and $0.05 million in foreign exchange gains realized upon the dissolution of BioLab 612, offset by a $0.5 million decrease in other income resulting from changes in the market value of our warrant liability.

Liquidity and Capital Resources

We have incurred net losses of approximately $169.1 million from our inception through December 31, 2020. Historically, we have not generated, and do not expect to generate in the immediate future, revenue from sales of product candidates. Since our founding in 2003, we have funded our operations through a variety of means:

We have incurred cumulative net losses and expect to incur additional losses related to our R&D activities. We do not have commercial products and have limited capital resources. As of December 31, 2020, we had $2.3 million in cash, cash equivalents and short-term investments which are expected to fund our projected operating requirements and allow us to fund our operating plan, in each case, into April 2022. Since December 31, 2020, we raised additional capital as a result of the registered direct offering we completed on February 23, 2021, resulting in net proceeds to us of approximately $12.7 million. However, until we are able to commercialize our product candidates at a level that covers our cash expenses, we will need to raise substantial additional capital, which we may be unable to raise in sufficient amounts, when needed and at acceptable terms. Additionally, the continued spread of COVID-19 and uncertain market conditions may limit the Company's ability to access capital. Our plans with regard to these matters may include seeking additional capital through debt or equity financing in public or private transactions, the sale or license of drug candidates, or obtaining additional research funding from the U.S. or Russian governments. There can be no assurance that we will be able to obtain future financing on acceptable terms, or at all, or that we can obtain additional government financing for our operations. If we are unable to raise adequate capital and/or achieve profitable operations, future operations might need to be scaled back or discontinued. The financial statements do not include any adjustments relating to the recoverability of the carrying amount of recorded assets and liabilities that might result from the outcome of these uncertainties.

In addition, the COVID-19 pandemic may negatively impact our ability to complete our planned preclinical and clinical trials, our ability to obtain approval of any product candidates from FDA or other regulatory authorities and our workforce and therefore our research and development activities.  This may ultimately have a material adverse effect on our liquidity, although we are unable to make any prediction with certainty given the rapidly changing nature of the pandemic and governmental and other responses to it.

Operating Activities

The following table provides information regarding our cash flows for the years ended December 31, 2020 and 2019:

Operating Activities

Net cash used in operations decreased by $0.3 million to $2.4 million for the year ended December 31, 2020 from $2.7 million for the year ended December 31, 2019. Net cash used in operating activities for the period ending December 31, 2020 consisted of a reported net loss of $2.4 million, which was further increased by $0.1 million of net non-cash operating activities, and decreased by $0.1 million due to changes in operating assets and liabilities. The $0.1 million of net non-cash operating activities consisted principally of changes in the valuation of our warrant liability offset by the gain on extinguishment of a 2019 revenue loss contingency. The net $0.1 million change in operating assets and liabilities was due to a continued decrease in working capital relating to accounts receivable and accounts payable. Net cash used in operating activities for the period ending December 31, 2019 consisted of reported net loss of $2.7 million, which was further increased by $0.1 million of net non-cash operating activities and offset by a $0.1 million change in operating assets and liabilities. The net non-cash operating activities of $0.1 million consisted principally of changes in the valuation of our warrant liability. The net $0.1 million change in operating assets and liabilities consisted primarily of an increase in accrued expenses related to a revenue loss contingency.

Investing Activities

Net cash provided by investing activities decreased by $0.1 million to $0.1 million for the year ended December 31, 2020 from $0.2 million for the year ended December 31, 2019. The net cash provided by investing activities for the years ended December 31, 2020 and 2019 consisted primarily of the net sales of short-term investments.

Financing Activities

Net cash provided by financing activities increased by $3.2 million to $3.2 million for the year ended December 31, 2020 from $0.0 million for the year ended December 31, 2019. Net cash provided by financing activities for the year ended December 31, 2020 consisted of proceeds from issuance of common stock and the exercise of warrants.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and

Stockholders of Cleveland BioLabs, Inc. and Subsidiaries

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Cleveland BioLabs, Inc. and Subsidiaries (the “Company”) as of December 31, 2020 and 2019, and the related consolidated statements of operations, comprehensive loss, stockholders’ equity, and cash flows, for each of the years in the two-year period ended December 31, 2020, and the related notes and schedules (collectively referred to as the “financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) related to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgements. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Going Concern:

The Company has incurred losses each year from inception through December 31, 2020, and continues to have negative cash flow from operations.  However, management believes, based on the current projections, including the impact of the February 2021 equity raise, that the Company will have enough funds to ensure continuing operations as a stand-alone entity for a period of at least one year from the issuance of these financial statements. 

We determined the Company’s ability to continue as a going concern is a critical audit matter due to the estimation and uncertainty regarding the Company’s future cash flows and the risk of bias in management’s judgments and assumptions in their determination. Our audit procedures related to the Company’s assertion on its ability to continue as a going concern included the following, among others:
