¹ Based on 22,285,492 shares of Common Stock outstanding as set forth in the Issuer’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on August 16, 2021.

Pursuant to Rule 13d-2 promulgated under the Act, this Amendment No. 2 to Schedule 13D (this “Amendment No. 2”) is being filed with respect to the common stock, par value $0.001 per share (“Common Stock”), of NeuroBo Pharmaceuticals, Inc. (the “Issuer”), to amend the Schedule 13D filed on March 11, 2021 (the “Original 13D” and, as amended by Amendment No. 1 filed on August 30, 2021 (“Amendment No. 1”), and this Amendment No. 2, the “Schedule 13D”). Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to them in the Schedule 13D.

Item 4.		Purpose of Transaction.

Item 4 of this Schedule 13D is hereby amended and supplemented to include the following:

On September 1, 2021, the Reporting Person submitted a non-binding proposal (the “Proposal”) to the board of directors of the Issuer (the “Board”) with respect to a potential licensing transaction (the “Potential Licensing Transaction”) whereby the Reporting Person and/or its affiliates would (i) exclusively license to the Issuer the worldwide (excluding South Korea) rights to DA-1241, DA-1726 and DA-7010, and (ii) grant the Issuer a right of first refusal in respect of DA-4210 (collectively, the “Subject DA Products”). The Reporting Person, the Issuer and/or one or more of their respective affiliates are expected to enter into a shared services agreement pursuant to which the Reporting Person would provide, or cause to be provided, assistance to the Issuer in the clinical development of the Subject DA Products on terms to be mutually agreed by the Reporting Person and the Issuer.

As previously disclosed, the proposed consideration in exchange for such licensing of the Subject DA Products may be shares of Common Stock (with registration rights with respect thereto), whether upfront, via royalty payments or upon achievement of certain milestones, which could result in a change in control of the Issuer in the event that the contemplated transactions are consummated.

The Potential Licensing Transaction would be contingent upon, among other things, the consummation of a concurrent financing providing sufficient capital to fund development of the Subject DA Products and the Issuer’s ongoing operations, obtaining any required regulatory consents, filing any requisite notices, approval by the Board and the requisite stockholders of the Issuer and other customary conditions for a transaction of this type.
