Draft Registration Statement on Form F-1 Submitted November 16, 2018 CIK No. 0001757064 Dear Mr. Mouney: We have reviewed your draft registration statement and have the following comments. In some of our comments, we may ask you to provide us with information so we may better understand your disclosure. Please respond to this letter by providing the requested information and either submitting an amended draft registration statement or publicly filing your registration statement on EDGAR. If you do not believe our comments apply to your facts and circumstances or do not believe an amendment is appropriate, please tell us why in your response. After reviewing the information you provide in response to these comments and your amended draft registration statement or filed registration statement, we may have additional comments. Draft Registration Statement on Form F-1 Cover Page 1. Please disclose on the cover page of the preliminary prospectus a bona fide price range of the offered securities. If you intend to price the securities based on the Euronext Paris price of your ordinary shares, you may disclose a percentage range based on that price (for example, 10% of the Euronext price) within which you intend to price the securities. See Item 501(b)(3) of Regulation S-K. Market, Industry and Other Data, page ii 2. Please disclose the information regarding the price history of your ordinary shares on Jean-Fran ois Mouney FirstName LastNameJean-Fran ois Mouney Genfit S.A. Comapany12, 2018 December NameGenfit S.A. December 12, 2018 Page 2 Page 2 FirstName LastName Euronext Paris pursuant to Item 9.A.4 of Form 20-F. Prospectus Summary Overview, page 1 3. We note statements throughout your prospectus that describe elabifranor as being "well- positioned" as a first-line treatment as a monotherapy and the backbone of combination regimens, statements that, "if approved, [you] believe elafibranor would be among the first FDA-approved therapies shown to achieve resolution of NASH without worsening of fibrosis" and statements that describe your blood-based IVD test as a novel, standalone diagnostic that will meet the need for a validated test to identify NASH patients as well as your statement on page 112 that describes the development and potential regulatory approval of elafibranor as being several years ahead of your competitors' drug candidates. These statements imply an expectation of regulatory approval and are inappropriate given the stage of development. Please revise these statements and all other similar statements to eliminate such implication. 4. We note statements throughout your prospectus referring to the safety or efficacy of your product candidates and diagnostic test. For example, we note your disclosure on page 3 that elabfibranor "has a differentiated efficacy and safety profile relative to other drugs in similar states of development for NASH" and that you "believe elafibranor has a favorable safety . . . profile" as well as your conclusions regarding the safety and efficacy of elabfibranor on pages 97 to 103 and page 108. Safety and efficacy are determinations within the exclusive authority of the FDA or equivalent foreign regulators, and, because your product candidates have not yet received approval by the FDA or equivalent foreign regulators, it is premature and inappropriate to state conclusions regarding safety and efficacy. Please revise these and all similar statements accordingly. 5. Please revise the pipleline chart on page 1 to clarify, if true, that you are conducting pre- clinical studies of TGFTX1 for mild to moderate psoriasis. In addition, we note your press release that you began your Phase 2 clinical trial of NTZ on December 3, 2018. Please revise your pipeline chart to indicate that you have just begun Phase 2 clinical trials of NTZ. Also, revise the pipeline chart of your IVD test to disclose the specific clearance and approval stages necessary to obtain FDA approval to market your IVD test. In this regard, we note your disclosure on pages 121 and 122. 6. We note your disclosure on page 2 that "[i]n [y]our Phase 2b clinical trial, elafibranor achieved resolution of NASH without worsening of fibrosis, which is the primary endpoint of [y]our ongoing global Phase 3 clinical trial." Please disclose here and in the second bullet point on page 3, if true, that you did not achieve statistical significance on your prespecified endpoints in your Phase 2b clinical trial. In this regard, we note your disclosure on page 15. 7. We note your disclosure on page 2 that "NTZ has shown promising activity against fibrosis in [y]our preclinical disease models." As NTZ is in clinical trials, please limit the Jean-Fran ois Mouney FirstName LastNameJean-Fran ois Mouney Genfit S.A. Comapany12, 2018 December NameGenfit S.A.

We note your disclosure on page 2 that you believe that, if the test results from your interim cohort analysis are positive, you may obtain accelerated approval from the FDA or the EMA as early as 2020 for elafibranor in the treatment of NASH. Please disclose whether you have received any indication from the FDA or EMA that you will be granted accelerated approval. In addition, to the extent that you have not conducted head-to-head clinical trials, revise your disclosure throughout your prospectus to remove comparisons of your product candidates to other treatments, products and product candidates. For example, we note your statements on page 2 that you "believe elafibranor's unique mechanism of action can provide benefits for patients with PBC without the significant side effects associated with current PBC treatments" and that your IVD test is better than the current standard for diagnosis of NASH and your statement on page 3 that elabfibranor resolves Nash "while also showing a decrease in cardiovascular risk factors, an important differentiator . . . ."
