Draft Registration Statement on Form S-1, Submitted November 16, 2020 About this Prospectus Market, Industry, and Other Data, page ii 1. We note that you state you have not independently verified any of the data from third- party sources nor have you ascertained the underlying economic assumptions relied upon therein. It is not appropriate to directly or indirectly disclaim liability for statements in your registration statement. Please revise or specifically state that you take liability for these statements. Summary, page 1 2. You state in the first paragraph that you use your SEE-Tx platform to "restore protein Eric Richman FirstName LastName Eric Richman Gain Therapeutics, Inc. Comapany13, December NameGain 2020 Therapeutics, Inc. December Page 2 13, 2020 Page 2 FirstName LastName folding and function and treat the underlying disease." Please balance your statement by clarifying that your platform is novel and untested, and that all of your product candidates remain in discovery or have not yet reached IND-enabling studies. 3. On page 1 you state: We have already identified and patented several novel Structurally Targeted Allosteric Regulators ( STARs ). However, we note your disclosure on page 74, which states that your only issued patent is in-licensed and relates to SEE-Tx, and your disclosure on page 7, where you state you hold three provisional patents. Please revise your discussion in this "Overview" section to highlight that your SEE-Tx platform technology is in-licensed, that you do not own any issued patents, and that neither the issued patent nor the pending patent applications cover the United States, and revise your bullet on page 7 accordingly. In addition, in your Business section, please expand your Intellectual Property discussion to also include a discussion of the European regulations. 4. Please revise page 3 to describe the random screening process and its reliance on supercomputing technology, and how it differs from your validated-target approach. 5. Please explain what is involved in "lead-OP" and why you believe this is a separate and distinct development phase, as opposed to part of your discovery or IND-enabling studies. Please also explain why you believe it is appropriate to present "in vitro" and "in vivo" as separate phases in the pipeline table. 6. Please tell us why you feel the undisclosed target for demyelinating disease should be included in your pipeline table on page 4 and elsewhere given its early stage and given that it is undisclosed and not further described in this prospectus. Please also remove the references to the Michael J. Fox Foundation and the Silverstein Foundation from the pipeline table as it does not appear that they are conducting the research with you but rather, have provided grants to you. 7. Please revise the references on pages 6-7 and elsewhere to rapidly advancing your lead product candidates into clinical development, and expedited regulatory approval strategies to avoid any implication that you have the ability to accelerate FDA approvals and commercialization of your products. Please briefly explain the FDA programs you may expect to rely on to seek accelerated approval. 8. We note your references in the Summary to various collaboration agreements and partnerships, but that you have not filed any of these agreements as a material agreement, and that you have limited disclosure regarding the terms of these arrangements in your Business section. To the extent these are not material agreements, please explain why it is appropriate to reference these arrangements in the Summary. To the extent they are material, please revise your disclosures as appropriate to disclose all material terms and file such agreements. In addition, please revise to disclose whether you have rights to all data produced in such partnerships or collaborations, or describe any material limitations.
