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

         prospectus summary discussion of your results to a description of the
endpoints of your
         clinical trials and whether they were met.
8.       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 . . . ."

9.       Please provide us with copies of all written communications, as
defined in Rule 405 under
         the Securities Act, that you, or anyone authorized to do so on your
behalf, present to
         potential investors in reliance on Section 5(d) of the Securities Act,
whether or not they
         retain copies of the communications.

We increasingly rely on social media, page 40

10.      We note your disclosure on page 40 that you "increasingly rely on
social media and new
         technologies to communicate to investors." To the extent that you
intend to communicate
         with investors on social media, please disclose how investors may
access such
         information. For example, please disclose whether you intend to
include such information
         in filings on the SEC website and your investor website.
Use of Proceeds, page 66

11.      If you do not believe that the anticipated proceeds will be sufficient
to complete all of the
         proposed purposes, please disclose an estimate of the additional funds
needed to fully
         fund all of the proposed purposes listed on page 66. In addition,
disclose an estimate
         of how far the allocated proceeds will allow you to reach in the
development process
         of (i) your IVD test and (ii) the research program on the use of
elafibranor as a potential
         backbone for combination therapies. If you do not believe that the
amount of funds
         allocated for your Phase 3 clinical trial of elafibranor for the
treatment of PBC and for the
         completion of your ongoing Phase 3 clinical trial for elafibranor for
the treatment of
         NASH will be sufficient to complete these Phase 3 clinical trials,
