GALECTIN THERAPEUTICS INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of Presentation and Liquidity

Galectin Therapeutics Inc. and subsidiaries (the “Company”) is a clinical stage biopharmaceutical company that is applying its leadership in galectin science and drug development to create new therapies for fibrotic disease and cancer. These candidates are based on the Company’s targeting of galectin proteins which are key mediators of biologic and pathologic function. These compounds also may have application for drugs to treat other diseases and chronic health conditions.

The unaudited condensed consolidated financial statements as reported in this Quarterly Report on Form

10-Q

reflect all adjustments which are, in the opinion of management, necessary to present fairly the financial position of the Company as of June 30, 2020 and the results of its operations for the three and six months ended June 30, 2020 and 2019 and its cash flows for the six months ended June 30, 2020 and 2019. All adjustments made to the interim financial statements include all those of a normal and recurring nature. Amounts presented in the condensed consolidated balance sheet as of December 31, 2019 are derived from the Company’s audited consolidated financial statements as of that date, but do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated through the date these financial statements are available to be issued. The results for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. The unaudited condensed consolidated financial statements of the Company should be read in conjunction with its Annual Report on Form

10-K

for the year ended December 31, 2019.

The Company has operated at a loss since its inception and has had no revenues. The Company anticipates that losses will continue for the foreseeable future. At June 30, 2020, the Company had $40,768,000 of unrestricted cash and cash equivalents available to fund future operations. The Company believes there is sufficient cash, including availability of the $10 million line of credit (see Note 3), to fund currently planned operations at least through September 30, 2021. We will require more cash to fund our operations after September 30, 2021 and believe we will be able to obtain additional financing. The currently planned operations include costs related to a planned adaptively designed

NASH-RX

Phase 2b/3 clinical trial. The costs of the trial along with drug manufacturing and other scientific support activities and general overhead during the first stage of the trial are currently estimated to be approximately $90 million. These costs will require additional funding. However, there can be no assurance that we will be successful in obtaining such new financing or, if available, that such financing will be on terms favorable to us. If we are unsuccessful in raising additional capital to fund operations before September 30, 2021, we may be required to cease operations. Accordingly, based on the forecasts and estimates underlying our current operating plan, the financial statements do not currently include any adjustments that might be necessary if we are unable to continue as a going concern.

The Company was founded in July 2000, was incorporated in the State of Nevada in January 2001 under the name

“Pro-Pharmaceuticals,

Inc.,” and changed its name to “Galectin Therapeutics Inc.” on May 26, 2011.

2. Accrued Expenses and Other

Accrued expenses consist of the following:


	June 30, 2020		December 31, 2019
	(in thousands)
Legal and accounting fees	$	129	$	81
Accrued compensation		861		973
Lease liability		41		39
Accrued research and development costs and other		2,972		—

Total	$	4,003	$	1,093

Research and development expenses, including personnel costs, allocated facility costs, lab supplies, outside services, contract laboratory costs are charged to research and development expense as incurred. The Company accounts for nonrefundable advance payments for goods and services that will be used in future research and development activities as expense when the service has been performed or when the goods have been received. Our current

NASH-RX

clinical trial is being supported by third-party contract research organizations, or CROs, and other vendors. We accrue expenses for clinical trial activities performed by CROs based upon the estimated amount of work completed on each trial. For clinical trial expenses and related expenses associated with the

Table of Contents

conduct of clinical trials, the significant factors used in estimating accruals include the number of patients enrolled, the number of active clinical sites, and the duration for which the patients have been enrolled in the trial. We monitor patient enrollment levels and related activities to the extent possible through internal reviews, review of contractual terms and correspondence with CROs. We base our estimates on the best information available at the time. We monitor patient enrollment levels and related activities to the extent possible through discussions with CRO personnel and based our estimates of clinical trial costs on the best information available at the time. However, additional information may become available to us which will allow us to make a more accurate estimate in future periods. In that event, we may be required to record adjustments to research and development expenses in future periods when the actual level of activity becomes more certain.

3. Line of Credit

On December 19, 2017, the Company entered into a $10 million Line of Credit arrangement with Richard E. Uihlein, a director and shareholder. Originally, borrowings may be made by the Company through December 31, 2018. Borrowings bear interest at the Applicable Federal Rate for short term loans published by the Internal Revenue Service (1.6% in December 2019). All borrowings and interest were originally due on December 31, 2019 but may be prepaid without penalty. In connection with the Line of Credit agreement, the Company issued to Mr. Uihlein warrants to purchase 1 million shares of the Company’s common stock for $5 per share. Half of the warrants vested at closing of the Line of Credit and the other half vest ratably with borrowings under the agreement. There have been no borrowings under the Line of Credit to date.

On December 20, 2018, the Line of Credit arrangement was extended for one year for both borrowings and maturity. At the time of the conversion of the Series B Convertible Preferred stock into common stock (See Note 9), on January 11, 2019, the Line of Credit arrangement was extended for an additional two years for both borrowings and maturity. After the second amendment to the Line of Credit arrangement, borrowings may be made through December 31, 2021 with repayment due on December 31, 2022. There was no additional consideration or benefits provided to Mr. Uihlein for any of the extensions of the Line of Credit.

The fair value of the 500,000 warrants vested at closing in December 2017 was $696,000 at the date of issuance based on the following assumptions: an expected life of 7 years, volatility of 98%, risk free interest rate of 2.05% and zero dividends. The fair value of the vested warrants was recorded in other current assets and other assets

(non-current)

as a deferred financing cost and were to be amortized on a straight-line basis from December 19, 2017 through December 31, 2019. The remaining unamortized balance of the deferred financing cost on January 11, 2019 was adjusted to be recorded as expense on a straight-line basis through December 31, 2022. Amortization for the six months ended June 30, 2020 and 2019 of $43,000 and $43,000, respectively, was recorded as interest expense. The fair value of warrants that vest in the future based on borrowings will be computed when those borrowings occur and amortized over the remaining period through December 31, 2022 reflecting the second extension.

4. Stock-Based Compensation

Following is the stock-based compensation expense related to common stock options, common stock, restricted common stock and common stock warrants:


	Three Months Ended June 30,				Six Months Ended June 30,
	2020		2019		2020		2019
Research and development	$	83	$	83	$	240	$	170
General and administrative		311		360		584		685

Total stock-based compensation expense	$	394	$	443	$	824	$	855

The following table summarizes the stock option activity in the Company’s equity incentive plans, including

non-plan

grants to Company executives, from December 31, 2019 through June 30, 2020:


	Shares			Weighted Average Exercise Price
Outstanding, December 31, 2019		3,000,256		$	4.88
Granted		845,000			2.47
Exercised		(84,624	)		2.61
Options forfeited/cancelled		(23,057	)		1.80

Outstanding, June 30, 2020		3,737,575		$	4.40

Table of Contents

As of June 30, 2020, there was $1,361,000 of unrecognized compensation related to 845,000 unvested options, which is expected to be recognized over a weighted–average period of approximately 2.09 years. The weighted-average grant date fair value for options granted during the six months ended June 30, 2020 was $1.92. The Company granted 845,000 stock options during the six months ended June 30, 2020.

The fair value of all other options granted is determined using the Black-Scholes option-pricing model. The following weighted average assumptions were used:


	Six Months Ended June 30,			Six Months Ended June 30,
	2020			2019
Risk-free interest rate		1.55	%		2.68	%
Expected life of the options		6 years			6 years
Expected volatility of the underlying stock		100	%		104	%
Expected dividend rate		0	%		0	%

In January 2019, two directors elected to take restricted stock grants in lieu of cash retainers for 2019. A total of 19,068 shares of restricted stock valued at approximately $90,000 was amortized to expense on a straight-line basis until January 16, 2020 when the stock vested in full.

In January 2020, two directors elected to take restricted stock grants in lieu of cash retainers for 2020. A total of 32,693 shares of restricted stock valued at approximately $93,500 is being amortized to expense on a straight-line basis until January 9, 2021 when the stock vests in full.

5. Common Stock Warrants

The following table summarizes the common stock warrant activity from December 31, 2019 through June 30, 2020:


	Shares		Weighted Average Exercise Price
Outstanding, December 31, 2019		12,538,204	$	4.22
Granted		—		—
Exercised		—		—
Forfeited/cancelled		—		—

Outstanding, June 30, 2020		12,538,204	$	4.22

The weighted average expiration of the warrants outstanding as of June 30, 2020 is 3.9 years.

6. Fair Value of Financial Instruments

The Company has certain financial assets and liabilities recorded at fair value. Fair values determined by Level 1 inputs utilize observable data such as quoted prices in active markets. Fair values determined by Level 2 inputs utilize data points other than quoted prices in active markets that are observable either directly or indirectly. Fair values determined by Level 3 inputs utilize unobservable data points in which there is little or no market data, which require the reporting entity to develop its own assumptions. The carrying amounts reflected in the consolidated balance sheets for cash equivalents, accounts payable and accrued expenses approximate their carrying value due to their short-term nature. There were no level 2 or level 3 assets or liabilities at June 30, 2020 or December 31, 2019.

7. Loss Per Share

Basic net loss per common share is computed by dividing the net loss available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net loss per common share is computed by dividing the net loss available to common stockholders by the weighted average number of common shares and other potential common shares then outstanding. Potential common shares consist of common shares issuable upon the assumed exercise of

in-the-money

stock options and warrants and potential common shares related to the conversion of the preferred stock. The computation of diluted net loss per share does not assume the issuance of common shares that have an anti-dilutive effect on net loss per share. Dilutive shares which could exist pursuant to the exercise of outstanding stock instruments and which were not included in the calculation because their affect would have been anti-dilutive are as follows:

	June 30, 2020 (shares)		June 30, 2019 (shares)
Warrants to purchase shares of common stock		12,538,204		12,540,679
Options to purchase shares of common stock		3,737,575		3,062,338

8. Common Stock

2020 At Market Issuance of Common Stock

On May 11, 2020, the Company entered into an At Market Issuance Sales Agreement (the “2020 At Market Agreement”) with a sales agent under which the Company may issue and sell shares of its common stock having an aggregate offering price of up to $40.0 million from time to time through the sales agent. Sales of the Company’s common stock through the sales agent, if any, will be made by any method that is deemed an “at the market” offering as defined by the U.S. Securities and Exchange Commission. The Company will pay to the sales agent a commission rate equal to 3.0% of the gross proceeds from the sale of any shares of common stock sold through the sales agent under the 2020 At Market Agreement. During the three months ended June 30, 2020, the Company issued 14,452 shares of its common stock under the 2020 At Market Agreement for net proceeds of approximately $44,000.

2017 At Market Issuance of Common Stock

On May 19, 2017, the Company entered into an At Market Issuance Sales Agreement (the “2017 At Market Agreement”) with a sales agent under which the Company may issue and sell shares of its common stock having an aggregate offering price of up to $30.0 million from time to time through the sales agent. Sales of the Company’s common stock through the sales agent, if any, will be made by any method that is deemed an “at the market” offering as defined by the U.S. Securities and Exchange Commission. The Company will pay to the sales agent a commission rate equal to 3.0% of the gross proceeds from the sale of any shares of common stock sold through the sales agent under the 2017 At Market Agreement. During the six months ended June 30, 2019, the Company issued 395,233 shares of its common stock under the 2017 At Market Agreement for net proceeds of approximately $1,865,000. There were no issuances of common stock under the 2017 At Market Agreement in 2020, and the 2017 At Market Agreement was terminated in May 2020.

For the six months ended June 30, 2020, the Company has issued a total of 30,875 shares of common stock for dividends on Series A and Series C Preferred Stock.

Rights Offering

On May 23, 2019, the Company completed an offering of common stock and warrants to its shareholders of record as of April 29, 2019. In the offering, the Company received approximately $44.9 million for the issuance of 10,488,161 shares of common stock and warrants which may be exercised for 2,622,154 shares of common stock. The warrants may be exercised at $7.00 per share of common stock and expire on May 23, 2026. The warrants were valued at approximately $8.2 million as of the issuance, using the closing price of $4.01, a life of 7 years, a volatility of 101% and a risk-free interest rate of 2.33%. Based upon the Company’s analysis of the criteria contained in ASC Topic

815-40,

“Derivatives and Hedging — Contracts in Entity’s Own Equity” the Company has determined that warrants issued in connection with this financing transaction were not derivative liabilities and therefore, were recorded as additional

paid-in

capital.

9. Preferred Stock Conversion into Common Stock

On January 11, 2019, 10X Fund L.P. (“10X Fund”), converted all of its Series B Convertible Preferred Stock into Common Stock of Galectin Therapeutics. Pursuant to the terms of the conversion, as of January 11, 2019, 10X Fund converted 5,508,000 shares of its Series

B-1,

B-2

and

B-3

Convertible Preferred Stock into 3,789,346 shares of Common Stock of Galectin Therapeutics. All special voting rights and protective provisions that previously benefited the Series B Preferred Stock were extinguished by the conversion to Common Stock.

In connection with the conversion of the Series B Preferred Stock, the Company extended by five years the exercise date of warrants for 3,579,642 shares of Common Stock issued by the Company in connection with sale of the Series

B-1

and Series

B-2

Preferred Stock. Before the extension, the warrants had various expiration dates in 2019 and 2020. The warrant amendments give 10X Fund the right to nominate one director to the Company’s board of directors. Previously, under the now extinguished voting rights of the Series B Preferred, 10X Fund had the right to name two directors and nominate an additional three directors.

Table of Contents

The Company has accounted for the modified terms of the warrants pursuant to ASC 718, Stock Compensation, whereby the Company has recognized a charge for the change in fair value of the warrants immediately before and immediately after the modification. In January 2019, the Company recognized a

one-time

non-cash

charge of $6,622,000 related to the extension of the 3,579,642 warrants. The following assumptions were used to value the extension of the warrants immediately before and immediately after the modification: a) immediately before the modification — an expected life range of 0.09 to 1.33 years, volatility of 98%, risk free interest rate range of 2.4% to 2.59% and zero dividends and; b) immediately following the modification — an expected life range of 5.09 to 6.33 years, volatility range of 106%, risk free interest rate range of 2.56% to 2.6% and zero dividends.

10. Commitments and Contingencies

Other Legal Proceedings

The Company records accruals for such contingencies to the extent that the Company concludes that their occurrence is probable and the related damages are estimable. There are no significant pending legal proceedings.

11. Leases

The Company has one operating lease for its office space which was amended effective January 1, 2019 for a term of 38 months with no residual value guarantees or material restrictive covenants. The amended lease provided for free rent for the first two months of the lease and continues the security deposit of $6,000. In addition to base rental payments included in the contractual obligations table above, the Company is responsible for our

pro-rata

share of the operating expenses for the building. Our lease cost for the

six-month

periods ended June 30, 2020 and 2019 was $22,000 for each period and is included in general and administrative expenses.

12. Galectin Sciences LLC

In January 2014, we created Galectin Sciences, LLC (the “LLC” or “Investee”), a collaborative joint venture

co-owned

by SBH Sciences, Inc. (“SBH”), to research and develop small organic molecule inhibitors of

galectin-3

for oral administration. The LLC was initially capitalized with a $400,000 cash investment to fund future research and development activities, which was provided by the Company, and specific

in-process

research and development (“IPR&D”) contributed by SBH. The estimated fair value of the IPR&D contributed by SBH, on the date of contribution, was $400,000. Initially, the Company and SBH each had a 50% equity ownership interest in the LLC, with neither party having control over the LLC. Accordingly, from inception through the fourth quarter of 2014, the Company accounted for its investment in the LLC using the equity method of accounting. Under the equity method of accounting, the Company’s investment was initially recorded at cost with subsequent adjustments to the carrying value to recognize additional investments in or distributions from the Investee, as well as the Company’s share of the Investee’s earnings, losses and/or changes in capital. The estimated fair value of the IPR&D contributed to the LLC was immediately expensed upon contribution as there was no alternative future use available at the point of contribution. The operating agreement provides that if either party does not desire to contribute its equal share of funding required after the initial capitalization, then the other party, providing all of the funding, will have its ownership share increased in proportion to the total amount contributed from inception. In the fourth quarter of 2014, after the LLC had expended the $400,000 in cash, SBH decided not to contribute its share of the funding required. Since then, the Company has contributed a total of $2,260,000, including $309,000 for the six months ended June 30, 2020, for expenses of the LLC. Since the end of 2014, SBH has contributed $158,000 for expenses in the LLC. As of June 30, 2020, the Company’s ownership percentage in the LLC was 82.6%. The Company accounts for the interest in the LLC as a consolidated, less than wholly owned subsidiary. Because the LLC’s equity is immaterial, the value of the

non-controlling

interest is also deemed to be immaterial.

Overview

We are a clinical stage biopharmaceutical company engaged in drug research and development to create new therapies for fibrotic disease, cancer and selected other diseases. Our drug candidates are based on our method of targeting galectin proteins, which are key mediators of biologic and pathologic functions. We use naturally occurring, readily-available plant products as starting material in manufacturing processes to create proprietary, patented complex carbohydrates with specific molecular weights and other pharmaceutical properties. These complex carbohydrate molecules are appropriately formulated into acceptable pharmaceutical formulations. Using these unique carbohydrate-based candidate compounds that largely bind and inhibit galectin proteins, particularly

galectin-3,

we are undertaking the focused pursuit of therapies for indications where galectins have a demonstrated role in the pathogenesis of a given disease. We focus on diseases with serious, life-threatening consequences to patients and those where current treatment options are limited. Our strategy is to establish and implement clinical development programs that add value to our business in the shortest period of time possible consistent with the natural history of the disease and to seek strategic partners when a program becomes advanced and requires significant additional resources.

Our lead

galectin-3

inhibitor is belapectin

(GR-MD-02),

which has been demonstrated in preclinical models to reverse liver fibrosis and cirrhosis. Belapectin has the potential to treat many diseases due to

galectin-3’s

involvement in multiple key biological pathways such as fibrosis, immune cell function and immunity, cell differentiation, cell growth, and apoptosis (cell death). The importance of

galectin-3

in the fibrotic process is supported by experimental evidence. Animals with the gene responsible for

galectin-3

“knocked-out”

can no longer develop fibrosis in response to experimental stimuli compared to animals with an intact

galectin-3

gene. Galectin Therapeutics Inc. is using its

galectin-3

inhibitor to treat advanced liver fibrosis and liver cirrhosis in NASH

(non-alcoholic

steatohepatitis) patients. We have completed two Phase 1 clinical studies, a Phase 2 clinical study in NASH patients with advanced fibrosis

(NASH-FX)

and a second Phase 2B clinical trial in NASH patients with well compensated cirrhosis

(NASH-CX).

We announced, in December 2017 top line results from our

NASH-CX

trial and results of an End of Phase 2 meeting with the FDA in May 2018 that provided direction on potentially acceptable end points for a Phase 3 trial. The latter was confirmed in a Type C meeting with FDA in February 2019. Thereafter, the Company with its external NASH consultants designed a Phase 3 study that was sent to various contract research organizations (CROs) for their input on feasibility, timing costs and other important considerations. At the request of the United States Food and Drug Administration (FDA), the trial protocol and answers to questions raised by FDA at the February meeting was submitted as a Type C (Written Response Only) request to FDA on July 17, 2019; this response sought FDA feedback and agreement with regards to the proposed clinical program. Further details on results of the

NASH-CX

trial were published in the journal Gastroenterology (Gastroenterology 2020;158:1334–1345).

Comments from FDA were received in late October 2019 and have been incorporated into the final version of the clinical trial protocol by the Company in conjunction with its hepatology consultants and medical and other experts at Covance, its chosen CRO. This modified trial design was discussed with FDA in a meeting on November 14, 2019 at which FDA indicated the design was reasonable (subject to a review of the protocol). The Company together with its advisors and Covance has modified the protocol and associated statistical analysis plans in conformance with the feedback received from FDA. and filed the protocol and various other documents with FDA on April 30, 2020. The study officially consented its first patient in June 2020. In addition, the Company has been working to some additional information requested by FDA which mostly relate to reporting of completed developmental toxicity studies.

Additionally, a study protocol entitled “A Single-dose, Open-label, Pharmacokinetic Study of

Belapectin

(GR-MD-02)

in Subjects With Normal Hepatic Function and Subjects With Varying Degrees of Hepatic Impairment” has been filed with FDA to examine the effects of the drug in subjects with normal hepatic function and subjects with varying degrees of hepatic impairment (study details are listed under study NCT04332432 on

www.clinicaltrials.gov

); this study is began enrolling patients in

Q2-2020.

A study protocol was filed with FDA on April 30, 2020 for a seamless adaptively-designed Phase 2b/3 clinical study, the

NASH-RX

trial, evaluating the safety and efficacy of its

galectin-3

inhibitor, belapectin

(GR-MD-02),

for the prevention of esophageal varices in patients with

non-alcoholic

steatohepatitis (NASH) cirrhosis (Further details are available at

www.clinicaltrials.gov

under study NCT04365868); this study began enrolling patients in

Q2-2020..

We endeavor to leverage our scientific and product development expertise as well as established relationships with outside sources to achieve cost-effective and efficient drug development. These outside sources, amongst others, provide us with expertise in preclinical models, pharmaceutical development, toxicology, clinical trial operations, pharmaceutical manufacturing, sophisticated physical and chemical characterization, and commercial development. We also have established several collaborative scientific discovery programs with leading experts in carbohydrate chemistry and characterization. These discovery programs are generally aimed at the targeted development of new carbohydrate molecules that bind galectin proteins and offer alternative options to larger market segments in our primary disease indications. We also have established through Galectin Sciences LLC, a discovery program aimed at the targeted development of small molecules (generally,

non-carbohydrate)

that bind galectin proteins and may afford options for alternative means of drug delivery (e.g., oral) and as a result expand the potential uses of our

galectin-3

inhibitor compounds. Initial results of the efforts at Galectin Sciences LLC were presented by Dr. E. Zomer at the AFDD meeting in Boston in Fall, 2019. Three series of composition of matter patents covering discoveries at Galectin Sciences have been filed. We are also pursuing a development pathway to clinical enhancement and commercialization for our lead compounds in immuno-oncology for cancer therapy. However, our clinical development efforts are primarily focused on liver fibrosis and NASH. All of our proposed products are presently in development, including

pre-clinical

and clinical trials.

Our Drug Development Programs

Galectins are a class of proteins that are made by many cells in the body, but predominantly in cells of the immune system. As a group, these proteins are able to bind to sugar molecules that are part of other proteins, glycoproteins, in and on the cells of our body. Galectin proteins act as a kind of molecular glue, bringing together molecules that have sugars on them. Galectin proteins, in particular

galectin-3,

are known to be markedly increased in a number of important diseases including inflammatory diseases, scarring of organs (e.g. liver, lung, kidney, and heart) and cancers of many kinds. The increase in galectin protein promotes the disease and is detrimental to the patient. Published data substantiating the importance of

galectin-3

in the fibrotic process arises from gene knockout experiments in animal studies. Mice genetically altered to eliminate the

galectin-3

gene, and thus unable to produce

galectin-3,

are incapable of developing liver fibrosis in response to toxic insult to the liver and in fatty liver disease as well as development of fibrosis in other tissues.

Table of Contents

We have one new proprietary chemical entity (NCE) in development, belapectin, which has shown promise in preclinical and early clinical studies in treatment of fibrosis, severe skin disease, and in cancer therapy. Currently we are focusing on development of belapectin intended to be used in the treatment of liver fibrosis associated with fatty liver disease (NASH) and more specifically in NASH cirrhosis. We have also leveraged our relationships with well-known investigators to demonstrate clinical effects of belapectin in treating moderate to severe plaque psoriasis, severe atopic dermatitis, and in cancer therapy in combination with immune-system modifying agent(s). Belapectin is a proprietary, patented compound derived from natural, readily available, plant-based starting materials, which, following chemical processing, exhibits the properties of binding to and inhibiting

galectin-3

proteins. A second NCE,

GM-CT-01

is a proprietary, patented compound that is made from a completely different starting source plant material and also binds and inhibits galectin proteins. Previously in clinical development for cancer indications,

GM-CT-01

compound has been explored in limited other preclinical studies.

Investigator initiated IND submitted for treatment of three patients with severe atopic dermatitis, with positive preliminary data presented in February 2017. Further studies are dependent on finding a suitable strategic partner.

Fibrosis.

Belapectin is our lead product candidate for treatment of fibrotic disease. Our preclinical data show that belapectin has a significant therapeutic effect on liver fibrosis as shown in several relevant animal models. In addition, in NASH animal models, belapectin has been shown to reduce liver fat, inflammation, and ballooning degeneration (death of liver cells). Therefore, we chose belapectin as the lead candidate in a development program targeted initially at fibrotic liver disease associated with

non-alcoholic

steatohepatitis (NASH). In January 2013, an Investigational New Drug (“IND”) was submitted to the FDA with the goal of initiating a Phase 1 study in patients with NASH and advanced liver fibrosis to evaluate the human safety of belapectin and pharmacodynamics biomarkers of disease. On March 1, 2013, the FDA indicated we could proceed with a US Phase 1 clinical trial for belapectin with a development program aimed at obtaining support for a proposed indication of belapectin for treatment of NASH with advanced fibrosis. The Phase 1 trial was completed and demonstrated that belapectin up to 8 mg/kg Lean Body Mass (LBM), i.v. was safe and well tolerated.

Additionally, an open label drug-drug interaction study was completed in healthy volunteers during the second quarter of 2015 with belapectin and it showed that with 8 mg/kg LBM dose of belapectin and 2 mg/kg dose of midazolam there was no drug-drug interaction and no serious adverse events or drug-related adverse events were observed. The secondary objective was to assess the safety and tolerability of belapectin when administered concomitantly with midazolam.

Our Phase 2 program in fibrotic disease consisted of two separate human clinical trials. The primary clinical trial was the Phase 2b

NASH-CX

study for one year for patients with NASH with compensated cirrhosis, which began enrolling in June 2015. This study was the primary focus of our program and is a randomized, placebo-controlled, double-blind, parallel-group Phase 2b trial to evaluate the safety and efficacy of belapectin for treatment of liver fibrosis and resultant portal hypertension in NASH patients with compensated cirrhosis. A smaller, exploratory

NASH-FX

trial was conducted to explore potential use of various

non-invasive

imaging techniques in NASH patients with advanced fibrosis but not cirrhosis.

Table of Contents

NASH-FX

Trial:

The

NASH-FX

trial, a Phase 2a pilot trial for patients with NASH and advanced fibrosis, explored use of three

non-invasive

imaging technologies, was completed. It was a short, single site, four-month trial in 30 NASH patients with advanced fibrosis (F3), but not cirrhosis (F4), randomized 1:1 to either

9 bi-weekly

doses of 8 mg/kg LBM of belapectin or placebo. The trial did not meet its primary biomarker endpoint as measured using multi-parametric magnetic resonance imaging (LiverMultiScan

(R)

, Perspectum Diagnostics). The trial also did not meet secondary endpoints that measure liver stiffness as a surrogate for fibrosis using, magnetic resonance-elastography and FibroScan

score. We, and many experts in the field, now believe that a four-month treatment period may not be sufficient to show efficacy results in established advanced liver fibrosis. This small study was also not adequately powered for the secondary endpoints. In the trial, belapectin was found to be safe and well tolerated with no serious adverse events and evidence of a pharmacodynamic effect. These results provided support for further development in NASH.

NASH-CX

Trial:

The

NASH-CX

trial was a larger multi-center clinical trial that explored the use of belapectin for the treatment of liver fibrosis and resultant portal hypertension in patients with well-compensated NASH cirrhosis. Enrollment in this trial was completed in September 2016, and a total of 162 patients at 36 sites in the United States were randomized to receive either 2 mg/kg LBM of belapectin, 8 mg/kg LBM of belapectin or placebo, with 54 patients in each group. Approximately 50% of patients at baseline had esophageal varices (a complication of portal hypertension). The primary endpoint was a reduction in hepatic venous pressure gradient (HVPG). Patients received an infusion of belapectin or placebo every other week for one year, a total of 26 infusions, and were evaluated to determine the change in HVPG as compared with placebo. Secondary or exploratory endpoints included fibrosis on liver biopsy, measurement of liver stiffness (FibroScan

(R)

) and assessment of liver metabolism (

C-methacetin

breath test, Exalenz). Top line data readout was reported in December 2017. The study demonstrated a favorable safety profile and clinically meaningful efficacy results in patients without esophageal varices at baseline demonstrated by a prevention of development of varices when compared to placebo.

In the total patient population, the primary endpoint HVPG showed a trend toward benefit with belapectin treatment, but the difference from placebo was not statistically significant. The mean change in HVPG of placebo from baseline to week 54 was 0.3 mm Hg. The mean change in HVPG from baseline was

-0.37

and

-0.42

for the 2 mg/kg LBM dose and 8 mg/kg LBM dose of belapectin, respectively.

In those NASH cirrhosis patients without varices at baseline (about 50% of the total population), there was a statistically significant effect of the 2 mg/kg LBM dose of belapectin on the absolute change in HVPG

(-1.08

mm Hg, p<0.01). The effect of the 8 mg/Kg LBM dose of belapectin on absolute or percent change in HVPG from baseline to week 54 was not significant.

Also because of the clinical relevance of this population, a responder analysis was performed on those patients without varices at baseline. Analysis was performed looking at two groups: those with an equal to or greater than 2 mm Hg decrease in HVPG from baseline or those with an equal to or greater than 2 mm Hg and a greater than or equal to 20% decrease in HVPG from baseline. In both cases, the change observed in the belapectin 2 mg/kg LBM group was statistically significant (p<0.01) while that of the 8 mg/kg LBM group was not.

Over the

54-week

treatment period, in patients without varices there were statistically significantly fewer new varices that developed in the belapectin treatment groups (0% and 4% in the 2 mg/kg LBM and the 8 mg/kg LBM, respectively) vs placebo (18%). As esophageal varices can lead to hemorrhagic complication, that can be fatal, we believe the prevention of esophageal varices may represent a clinically relevant measure of clinical efficacy in patients with NASH cirrhosis.

The major conclusions from the

NASH-CX

trial results are that: i) belapectin had a statistically significant and clinically meaningful effect in improving HVPG vs placebo in patients with NASH cirrhosis who did not have esophageal varices at baseline. This effect was seen regardless of the patient’s baseline portal hypertension. ii) There was an important drug effect of belapectin in the total patient population on liver biopsy with a statistically significant improvement in hepatocyte ballooning (ie cell death), (iii) There was a statistically significant reduction (p=0.02) in the development of new esophageal varices in drug-treated patients compared to placebo. We believe that this is a clinically relevant endpoint related to patient outcomes, (iv) While there was a drug effect in both the 2 mg/kg LBM and 8 mg/kg LBM groups on the development of varices and liver biopsy there was a consistently greater and statistically significant effect of the 2 mg/kg LBM dose of belapectin, (v) belapectin appears to be safe and well tolerated in this one year clinical trial, a feature that is of prime importance for a cirrhotic population and (vi) We believe this is the first large, randomized clinical trial to demonstrate a clinically meaningful improvement in portal hypertension or liver biopsy in patients with compensated NASH cirrhosis who have not yet developed esophageal varices.

Further information and details on the

NASH-CX

results summarized above is available in public presentations posted to our website and filed with the SEC and in a peer reviewed publication in

Gastroenterology

(Gastroenterology 2020;158:1334–1345).

NASH-RX

Trial:

Building on the experience of the

NASH-CX

trial, the

NASH-RX

Trial is a seamless adaptively-designed Phase 2b/3 clinical study evaluating the safety and efficacy of our

galectin-3

inhibitor, belapectin

(GR-MD-02),

for the prevention of esophageal varices in patient with

non-alcoholic

steatohepatitis (NASH) cirrhosis. The major features of this innovative Phase 2b/3 study design are: i) In patients with NASH cirrhosis and clinical signs of portal hypertension but without esophageal varices at baseline, this trial will assess the effect of belapectin on the incidence of new varices (the primary endpoint) – as well as assessing effect on the incidence of long-term, clinically significant cirrhosis-related outcomes (a key secondary efficacy endpoint), (ii) The study targets NASH patients with a clearly identified unmet medical need: patients with compensated cirrhosis who are at risk of developing esophageal varices, a potentially life-threatening complication of cirrhosis (bleeding varices are a cause of death in about

one-third

of cirrhotic patients). There is no approved treatment for preventing varices in these patients. In addition, the development of esophageal varices reflects the progression of hepatic cirrhosis and thus portends the development of other cirrhosis complications such as ascites, hepatic encephalopathy, and liver failure, and (iii) During the first 18 months, two belapectin dose levels (2 mg/kg LBM and 4 mg/kg LBM) will be compared to placebo (phase 2b). Then, at the interim analysis (IA), one belapectin dose will be selected based on efficacy and safety, for continued evaluation (Phase 3). The belapectin dose selected for the phase 2b/3 are based on the analysis of the

NASH-CX

trial, including a dose response pharmacokinetic analysis of the hepatic venous gradient pressure (HVPG, a reflection of portal hypertension). Prior belapectin clinical studies have also indicated the good tolerance and safety profile of belapectin with doses of up to 8 mg/kg LBM for 52 weeks (Phase 2b Study

NASH-CX),

an important feature of the future risk benefit analysis in patients with NASH cirrhosis.

The study design provides for a

pre-specified

interim analysis (IA). The IA of efficacy and safety data will be conducted after all planned subjects in Phase 2b component have completed at least 78 weeks (18 months) of treatment and an esophago-gastro-duodeno endoscopic assessment. The purpose of the IA is to allow potential seamless adaptive modifications of the study, including: (1) the selection of the optimal dose of belapectin for Phase 3, (2) the

re-estimation

of the study sample size for Phase 3 portion of the trial, (3) the

re-evaluation

of the randomization ratio for the Phase 3 portion of the trial, (4) the refinement of the inclusion and exclusion criteria for the Phase 3 portion of the trial, including the cirrhosis status, (5) and/or termination of the study for overwhelming efficacy or for futility.

The trial design also includes a blinded sample size

re-estimation

(“SSR”) during the Phase 2b, prior to the IA, to allow for potential sample size readjustment. The SSR will be conducted when 50% of the patients have completed 18 months of therapy. This will allow to confirm the underlying assumption regarding the rate of varices development, currently estimated from our prior Phase 2b trial

(NASH-CX).

The study design also minimizes invasive testing requirements, such as the measurement of HVPG or repeated liver biopsies, which we believe will facilitate enrollment and retention of patients. It also provides for a seamless transition of patients from the phase 2b component into the phase 3 stage, including the potential addition of new patients. The trial design preserves the surrogate

end-point

concepts (development of new varices versus variceal hemorrhage) previously discussed with FDA.

We believe that these adaptations taken together are innovative and optimize conduct of the

NASH-RX

trial with a relevant primary outcome giving belapectin the best opportunity to show a positive therapeutic effect to address an unmet medical need. If the results of the

NASH-RX

trial are compelling, there could be the potential for accelerated FDA approval and/or partnership opportunity with a pharmaceutical company.

In the Phase 3 component of this trial, as proposed in the protocol, the primary endpoint remain the development of varices. Secondary endpoints include a composite clinical outcomes endpoint, including varices requiring treatment (development of large varices or varices with a red wale), decompensating events,

all-cause

mortality, MELD score increase, liver transplant. Also, NASH

non-invasive

biomarkers will be evaluated. To target a population at risk of developing esophageal varices, patient selection will be based on clinical signs of portal hypertension, including, a low platelet count, an increased spleen size and/or evidence of collaterals circulation.

The focus and goal of the therapeutic program is to stop the progression of and/or reverse portal hypertension and thereby prevent the development of varices, potentially one of the most immediately life-threatening complication of cirrhosis. Based on the results of the

NASH-CX

trial and subject to confirmation in later stage clinical trials, we believe that this goal is achievable in a significant portion of the NASH cirrhosis patient population i.e. those NASH cirrhosis patients with clinical signs of portal hypertension.

We currently expect enrollment in the Phase 2(b) portion of the trial to be require

12-14

months and enrollment began in June 2020. This remains subject to potential site delays due to the impact of the global

COVID-19

pandemic.

Our CRO has identified more than 125 clinical trial sites in 11 countries interested in the trial.

Further details on the

NASH-RX

trial can be found on

www.clinicaltrials.gov

under study NCT04365868.

The Company also has commenced a Hepatic Impairment Study, which will run in parallel with the phase 2b/3 trial as part of the Phase 3 development program. The Hepatic Impairment Study will be conducted at up to four sites and will involve approximately 40 patients (divided amongst normal healthy volunteers, and patients with hepatic impairment categorized as Child-Turcotte-Pugh (CTP) classes A (mild), B (moderate), and C (severe)). Each subject will receive a single infusion of belapectin (4 mg/kg LBM) and their serum belapectin levels will be monitored for up to approximately two weeks to define the effects of various stages of cirrhosis on serum belapectin levels and safety. Based on the results from this hepatic impairment study, the Company may consider including patients with more advanced cirrhosis in the Phase 3 portion of its

NASH-RX

trial. Until dosing and safety profile is further informed in CTP Class B and/or Class C patients, the

NASH-RX

trial will enroll only CTP Class A patients. Further details on this hepatic impairment study can be found on

www.clinicaltrials.gov

study NCT04332432.

Cancer Immunotherapy.

We believe there is potential for galectin inhibition to play a key role in the burgeoning area of cancer immunotherapy. For example, there have been several recent approvals of drugs that enhance a patient’s immune system to fight cancer. It is our goal to use a galectin inhibitor to further enhance the immune system function to fight cancer in a way that complements other approaches to this type of therapy. This hypothesis is supported by the fact that

galectin-3

is expressed at high levels in multiple types of tumors, adds to the malignant nature of the tumors, and protects the tumors from immune system attack. Our drug candidates provide a promising new therapeutic approach to enhance the activity of the immune system against cancer cells. Preclinical studies have indicated that belapectin enhances the immune response to cancer cells, increased tumor shrinkage and enhanced survival in immune competent mice with prostate, breast, melanoma and sarcoma cancers when combined with one of the immune checkpoint inhibitors,

anti-CTLA-4

anti-PD-1,

or with the immune cell activator anti-OX40. These preclinical data led to the filing of two Investigator-sponsored INDs and the initiation of studies of belapectin in combination with Yervoy

(ipilimumab) and KEYTRUDA (pembrolizumab) in Phase 1B studies of patients with metastatic melanoma. The KEYTRUDA trial has also been expanded to include patients with

non-small

cell lung cancer and head and neck squamous cell carcinoma. These studies are being conducted under the sponsorship of Providence Portland Medical Center’s Earle A. Chiles Research Institute (EACRI).

Data on this combination immunotherapy program was initially presented on February 7, 2017 at the 9th GTCBio Immunotherapeutics & Immunomonitoring Conference in San Diego, CA by Dr. William L. Redmond, Providence Cancer Center. Preclinical results in mouse models of multiple types of cancers showed important anti-tumor activity and increased survival effects of combining belapectin with different types of immune modulators, providing a case for progressing studies into human patients with cancer. Seven patients were treated in the belapectin trial in combination with ipilimumab (Yervoy

), with no safety concerns in these low dose cohorts. Due to changes in the standard of care for metastatic melanoma (i.e., approval of

anti-PD-1),

recruitment has been slowed significantly in this trial.

Promising results were reported in the Phase 1b trial combining belapectin with pembrolizumab (KEYTRUDA

). Cohort 1 was completed (n=6, 5 with melanoma, one with head and neck cancer) with one partial response and one mixed response in the melanoma patients. There was a rapid and marked tumor response after 3 doses of combined belapectin and pembrolizumab in the one partial response patient who had failed high-dose

IL-2

and oncolytic virus + ipilimumab. The study is ongoing and progression to further development will be based on response rate as compared to historical response rates to pembrolizumab alone. In September 2018 we announced additional preliminary clinical data from cohort 3 of this investigator-initiated trial. When aggregated with cohorts previously reported, the data shows a 50% objective response rate in advanced melanoma with belapectin in combination with KEYTRUDA, and a significant decrease in the frequency of suppressive myeloid-derived suppressor cells following treatment in the responding patients (on day 85 post-treatment). Fourteen advanced melanoma patients across three dose cohorts now have Objective Response Rate (ORR) and Disease Control Rate (DCR) data. Six patients completed in cohort 3 (8 mg/kg) have now been added to the three patients completed in cohort 2 (4 mg/kg) and five patients completed in cohort 1 (2 mg/kg). Cohorts 1 and 3 each had two patients with an objective response. All three patients in cohort 2 had an objective response. In addition to the fourteen advanced melanoma patients, six patients with head and neck cancer were enrolled in this trial with a 33% ORR and 67% DCR. These data, taken together with the observed favorable safety and tolerability of the combination, in the view of the principal investigator, provide compelling rationale to move forward. Given that all three melanoma patients were responders at the 4 mg/kg dose, the investigators plan to continue the trial with the expansion of the 4 mg/Kg cohort to include additional advanced melanoma patients and additional head and neck cancer patients. The expansion cohort will target to include 15 patients and is planned to have continued belapectin dosing as long as pembrolizumab is administered. Currently more than 40% of the patients in the expansion cohort have been enrolled and further information will be reported as it becomes available. Assuming these additional data are positive, the next logical step could be a Phase II trial.

Severe skin diseases.

During our Phase 1 NASH fibrosis trial with belapectin, a clinical effect on plaque psoriasis was observed in a NASH patient who also had this disease. This patient had marked improvement in her psoriasis, with improvement beginning after the third infusion. She reported that her psoriasis was “completely gone” and her skin was “normal” after the fourth infusion. Her skin remained normal for 17 months after the final infusion of study drug. The patient is convinced that the improvement in her psoriasis is related to the study drug.

This serendipitous finding, combined with

galectin-3

protein being markedly upregulated in the capillary epithelia (small blood vessels) of the psoriatic dermis (plaque lesions), led to a phase 2a trial in patients with moderate to severe plaque psoriasis. Belapectin inhibition of

galectin-3

may attenuate capillary changes in the psoriatic dermis and inflammatory cell recruitment, perhaps explaining the improvements observed in the NASH fibrosis trial patient. In this open-label, unblinded trial (no placebo, all patients knowingly receive active drug), 5 patients with moderate to severe plaque psoriasis were administered belapectin every two weeks for 24 weeks. In May 2016, we reported positive results on the first four patients after 12 weeks of therapy. Based on these results, we modified the trial to include 24 weeks of therapy. In August 2016, we reported on four patients after 24 weeks of therapy and one patient after 12 weeks of therapy. The four patients who received 24 weeks of therapy experienced an average of 48% improvement in their plaque

Table of Contents

psoriasis. At this time, the average response in all five patients remains at 50% with one patient having an 82% improvement. However, there are existing drugs on the market in this disease that produce 75% and higher improvements in

60-90%

of patients. While we are encouraged that this study has demonstrated clinically meaningful results in a human disease with belapectin, the next steps would entail a controlled, does-ranging clinical trial which we do not expect to conduct absent a strategic partnership.

We believe the mechanism of action for belapectin is based upon interaction with, and inhibition of, galectin proteins, particularly

galectin-3,

which are expressed at high levels in certain pathological states including inflammation, fibrosis and cancer. While belapectin is capable of binding to multiple galectin proteins, we believe that it has the greatest affinity for

galectin-3,

the most prominent galectin implicated in pathological processes. Blocking galectin in cancer and liver fibrosis has specific salutary effects on the disease process, as discussed previously.

We generally categorize research and development expenses as either direct external expenses, comprised of amounts paid to third party vendors for services, or all other research and development expenses, comprised of employee payroll and general overhead allocable to research and development. We consider a clinical program to have begun upon acceptance by the FDA, or similar agency outside of the United States, to commence a clinical trial in humans, at which time we begin tracking expenditures by the product candidate. Clinical program expenses comprise payments to vendors related to preparation for, and conduct of, all phases of the clinical trial, including costs for drug manufacture, patient dosing and monitoring, data collection and management, oversight of the trials and reports of results.

Pre-clinical

expenses comprise all research and development amounts incurred before human trials begin, including payments to vendors for services related to product experiments and discovery, toxicology, pharmacology, metabolism and efficacy studies, as well as manufacturing process development for a drug candidate.

Our research and development expenses were as follows:


	Three Months Ended June 30,				Six Months Ended June 30,
	2020		2019		2020		2019
	(in thousands)
Direct external expenses:
Clinical programs	$	3,779	$	944	$	4,798	$	930
Pre-clinical activities		121		17		363		101
All other research and development expenses		781		561		1,664		1,137

	$	4,681	$	1,522	$	6,825	$	2,168

Clinical programs expenses increased primarily due to costs related to our

NASH-RX

trial during the three and six month periods ended June 30, 2020 as compared to the same periods ended June 30, 2019. Other research and development expense increased primarily due to increased payroll related to the hiring of Dr. Pol Boudes as Chief Medical Officer in March 2020.

Both the time required and costs we may incur in order to commercialize a drug candidate that would result in material net cash inflow are subject to numerous variables, and therefore we are unable at this stage of our development to forecast useful estimates. Variables that make estimates difficult include the number of clinical trials we may undertake, the number of patients needed to participate in the clinical trial, patient recruitment uncertainties, trial results as to the safety and efficacy of our product, and uncertainties as to the regulatory agency response to our trial data prior to receipt of marketing approval. Moreover, the FDA or other regulatory agencies may suspend clinical trials if we or an agency believes patients in the trial are subject to unacceptable risks or find deficiencies in the conduct of the clinical trial. Delays or rejections may also occur if governmental regulation or policy changes during our clinical trials or in the course of review of our clinical data. Due to these uncertainties, accurate and meaningful estimates of the ultimate cost to bring a product to market, the timing of costs and completion of our program and the period during which material net cash inflows will commence are unavailable at this time.

General and Administrative Expense.


									2020 as Compared to 2019
	Three Months Ended June 30,				Six Months Ended June 30,				Three Months					Six Months
	2020		2019		2020		2019		$ Change		% Change			$ Change		% Change

General and administrative	$	1,421	$	1,498	$	2,861	$	3,219	$	(77)		(5	)%	$	(358)		(11	)%

General and administrative expenses consist primarily of salaries including stock-based compensation, legal and accounting fees, insurance, investor relations, business development and other office related expenses. The primary reasons for the decrease in general and administrative expenses for the three-months ended June 30, 2020 as compared to the same period in 2019 is due to a decrease in

non-cash

stock compensation expense of approximately $48,000. The primary reasons for the decrease in general and administrative expenses for the

six-months

ended June 30, 2020 as compared to the same period in 2019 is due to a decrease in

non-cash

stock compensation expense of approximately $101,000 and a decrease in legal expenses of $264,000 partially offset by an increase in insurance expense of $138,000.

Liquidity and Capital Resources

Since our inception on July 10, 2000, we have financed our operations from proceeds of public and private offerings of debt and equity. As of June 30, 2020, we raised a net total of $197.4 million from these offerings. We have operated at a loss since our inception and have had no significant revenues. We anticipate that losses will continue for the foreseeable future. At June 30, 2020, the Company had $40.8 million of unrestricted cash and cash equivalents available to fund future operations. In December 2018, the Company announced the extension of its $10 million unsecured line of credit facility with stockholder and director, Richard E. Uihlein. The Company has not drawn under the line of credit. The Company believes there is sufficient cash, including availability of the line of credit, to fund currently planned operations at least through September 30, 2021. We will require more cash to fund our operations after September 30, 2021 and believe we will be able to obtain additional financing. The currently planned operations include costs related to a planned adaptively designed Phase 2b/3 clinical trial. The costs of the trial along with drug manufacturing and scientific support activities and general overhead during the first stage of the Phase 3 trial are currently estimated to be approximately $90 million. We will require additional funding in order to complete the trial. However, there can be no assurance that we will be successful in obtaining such new financing or, if available, that such financing will be on terms favorable to us.

Net cash used in operations increased by $1,361,000 to $6,975,000 for the six months ended June 30, 2020, as compared to $5,614,000 for the six months ended June 30, 2019. Cash operating expenses increased principally due to our

NASH-RX

clinical trial with belapectin.

Net cash provided by financing activities for the six months ended June 30, 2020, of $263,000 represents proceeds of $219,000 from the exercise of common stock options and $44,000 in net proceeds from issuance of common shares under our ATM. Net cash provided by financing activities for the six months ended June 30, 2019, of $49,404,000 represents proceeds from the issuance of common stock from the stockholder rights offering of $44,889,000, from the ATM of $1,865,000 and $2,650,000 from the exercise of common stock options and warrants.

Off-Balance

Sheet Arrangements

We have not created, and are not a party to, any special-purpose or

off-balance

sheet entities for the purpose of raising capital, incurring debt or operating parts of our business that are not consolidated into our financial statements. We do not have any arrangements or relationships with entities that are not consolidated into our financial statements that are reasonably likely to materially affect our liquidity or the availability of capital resources.

Application of Critical Accounting Policies and Estimates

The preparation of condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to accrued expenses, stock-based compensation, contingencies and litigation. We base our estimates on historical experience, terms of existing contracts, our observance of trends in the industry, information available from other outside sources and on various other factors that we believe to be appropriate under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

Critical accounting policies are those policies that affect our more significant judgments and estimates used in preparation of our consolidated financial statements. We believe our critical accounting policies include our policies regarding stock-based compensation, accrued expenses and income taxes. For a more detailed discussion of our critical accounting policies, please refer to our 2019 Annual Report on Form

10-K.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Market risk represents the risk of loss that may impact our financial position, operating results or cash flows due to changes in the U.S. interest rates. The primary objective of our investment activities is to preserve cash until it is required to fund operations. To minimize risk, we maintain our portfolio of cash and cash equivalents in operating bank accounts and money market funds. Since our investments are short-term in duration, we believe that we are not subject to any material market risk exposure.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of the Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule

13a-15(e)

promulgated under the Securities Exchange Act of 1934) and concluded that, as of June 30, 2020, our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

During the quarter ended June 30, 2020, no change in our internal control over financial reporting has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 1A. Risk Factors

The information set forth in this report should be read in conjunction with the risk factors set forth in Item 1A, “Risk Factors,” of Part I of our Annual Report on Form

10-K

for the year ended December 31, 2019, which could materially impact our business, financial condition or future results.

The outbreak of the novel strain of coronavirus,

SARS-CoV-2,

which causes

COVID-19,

could adversely impact our business, including our preclinical studies and clinical trials.

Public health crises such as pandemics or similar outbreaks could adversely impact our business. In December 2019, a novel strain of coronavirus,

SARS-CoV-2,

which causes coronavirus disease 2019

(“COVID-19”),

surfaced in Wuhan, China. Since then,

COVID-19

has spread to multiple countries, including the United States. In response to the spread of

COVID-19,

we have closed our executive offices with our administrative employees continuing their work outside of our offices, restricted

on-site

staff to only those required to execute their job responsibilities and limited the number of staff in any given research and development laboratory.

As a result of the

COVID-19

outbreak, or similar pandemics, we have and may in the future experience disruptions that could severely impact our business and our anticipated rollout and/or continuation of our Phase 2b/3

NASH-RX

trial, including:

•

delays or difficulties in enrolling patients in our clinical trials;

•

delays or disruptions in

non-clinical

experiments due to unforeseen circumstances at contract research organizations and vendors along their supply chain;

•

increased rates of patients withdrawing from our clinical trials following enrollment as a result of contracting

COVID-19,

being forced to quarantine, or not accepting in office or home health visits;

•

diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as sites for our

NASH-RX

trials and hospital staff supporting the conduct of such trials;

•

interruption of key clinical trial activities, such as clinical trial site data monitoring, due to limitations on travel imposed or recommended by federal or state governments, employers and others or interruption of clinical trial subject visits and study procedures (particularly any procedures that may be deemed

non-essential),

which may impact the integrity of subject data and clinical study endpoints;

•

interruption or delays in the operations of the FDA and comparable foreign regulatory agencies, which may impact review and approval timelines;

•

interruption of, or delays in receiving, supplies of our product candidates from our contract manufacturing organizations due to staffing shortages, production slowdowns or stoppages and disruptions in delivery systems; and

•

limitations on employee resources that would otherwise be focused on the conduct of our preclinical studies and clinical trials, including because of sickness of employees or their families, the desire of employees to avoid contact with large groups of people, an increased reliance on working from home or mass transit disruptions.

These and other factors arising from the

COVID-19

pandemic could worsen in countries that are already afflicted with

COVID-19,

could continue to spread to additional countries, or could return to countries where the pandemic has been partially contained, each of which could further adversely impact our ability to conduct clinical trials and our business generally, and could have a material adverse impact on our operations and financial condition and results.

In addition, the trading prices for our common stock and other biopharmaceutical companies have been highly volatile as a result of the

COVID-19

epidemic. As a result, we may face difficulties raising capital through sales of our common stock or such sales may be on unfavorable terms. The

COVID-19

outbreak continues to rapidly evolve. The extent to which the outbreak may impact our business, preclinical studies and clinical trials 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, travel restrictions and actions to contain the outbreak or treat its impact, such as social distancing and quarantines or lock-downs 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.

Equity [Abstract]
Common Stock	8. Common Stock 2020 At Market Issuance of Common Stock On May 11, 2020, the Company entered into an At Market Issuance Sales Agreement (the “2020 At Market Agreement”) with a sales agent under which the Company may issue and sell shares of its common stock having an aggregate offering price of up to $40.0 million from time to time through the sales agent. Sales of the Company’s common stock through the sales agent, if any, will be made by any method that is deemed an “at the market” offering as defined by the U.S. Securities and Exchange Commission. The Company will pay to the sales agent a commission rate equal to 3.0% of the gross proceeds from the sale of any shares of common stock sold through the sales agent under the 2020 At Market Agreement. During the three months ended June 30, 2020, the Company issued 14,452 shares of its common stock under the 2020 At Market Agreement for net proceeds of approximately $44,000. 2017 At Market Issuance of Common Stock On May 19, 2017, the Company entered into an At Market Issuance Sales Agreement (the “2017 At Market Agreement”) with a sales agent under which the Company may issue and sell shares of its common stock having an aggregate offering price of up to $30.0 million from time to time through the sales agent. Sales of the Company’s common stock through the sales agent, if any, will be made by any method that is deemed an “at the market” offering as defined by the U.S. Securities and Exchange Commission. The Company will pay to the sales agent a commission rate equal to 3.0% of the gross proceeds from the sale of any shares of common stock sold through the sales agent under the 2017 At Market Agreement. During the six months ended June 30, 2019, the Company issued 395,233 shares of its common stock under the 2017 At Market Agreement for net proceeds of approximately $1,865,000. There were no issuances of common stock under the 2017 At Market Agreement in 2020, and the 2017 At Market Agreement was terminated in May 2020. For the six months ended June 30, 2020, the Company has issued a total of 30,875 shares of common stock for dividends on Series A and Series C Preferred Stock. Rights Offering On May 23, 2019, the Company completed an offering of common stock and warrants to its shareholders of record as of April 29, 2019. In the offering, the Company received approximately $44.9 million for the issuance of 10,488,161 shares of common stock and warrants which may be exercised for 2,622,154 shares of common stock. The warrants may be exercised at $7.00 per share of common stock and expire on May 23, 2026. The warrants were valued at approximately $8.2 million as of the issuance, using the closing price of $4.01, a life of 7 years, a volatility of 101% and a risk-free interest rate of 2.33%. Based upon the Company’s analysis of the criteria contained in ASC Topic 815-40, “Derivatives and Hedging — Contracts in Entity’s Own Equity” the Company has determined that warrants issued in connection with this financing transaction were not derivative liabilities and therefore, were recorded as additional paid-in capital.
