Information Statement Summary
Product Candidates, page 7

2.       We note the inclusion of the product candidate "UC1MT" for the
indications of
         inflammatory and autoimmune diseases and certain other preclinical
product candidates in
         your pipeline table labeled "BHV-TBD." In addition, we note your
disclosure on page 112
         that you "currently operate in a single business segment developing a
portfolio of
         innovative, late-stage product candidates targeting neurological
diseases." Given the
         limited disclosure related to UC1MT, please explain why it is
sufficiently material to your
         business to warrant inclusion in your pipeline table. If it is
material, please expand your
         disclosure in the Business section to provide a more fulsome
discussion of this candidate,
         including a description of preclinical studies, development activities
conducted, or
         ongoing clinical trials. Alternatively, remove UC1MT and any other
preclinical product
         candidates that are not currently material to your business from your
pipeline table on
         pages 7 and 75.

3.       We note disclosure here stating Biohaven Research Ltd will be assigned
liabilities
         resulting from "certain specified legal proceedings." We further note
disclosure in your
         Legal Proceedings section stating you are currently not party to any
material legal
         proceedings. Please reconcile your disclosure or advise.
Business
Product Candidates, page 75

4.       Please remove the references throughout your information statement to
"first-in-class" or
         "best-in-class" product candidates as these descriptions imply an
expectation of regulatory
         approval and are inappropriate given the length of time and
uncertainty with respect to
         securing marketing approval.
5.       Please revise any statements concluding your product candidates are
safe or effective to
         instead refer to objective trial results. For example only, we note
disclosure on page 75
         where you state that your Kv7 platform is a "potent" activator, on
page 82 where you state
         that troriluzole demonstrated "acceptable safety" consistent with past
clinical trial
         experiences and on page 87 where you state "BHV-2100 shows promising
efficacy."
         Please remove these statements, and any similar statements, as
conclusions of safety and
         efficacy are within the sole authority of the FDA and comparable
foreign regulators.
6.       At first use, please define abbreviations. For example only, we note
that "SCA," "ALS"
         and "SMA" are not defined at first use.
7.       In your discussion of the preclinical and clinical development of your
material programs,
         please revise your disclosure to specify the following information
with respect to the trials

         that you have conducted, are currently conducting or plan to conduct:
             the trial design;
             the number of participants in the trial;
             the primary and secondary endpoints as well as the results as they
relate to those
              endpoints; and
             the occurrence of any serious adverse events.

         As example only, we refer to your disclosure on page 125 that
"Troriluzole was well
         tolerated with a safety profile consistent with past clinical trial
experience." Please revise
         to expand your disclosure to discuss the observance of any serious
adverse events for each
         of you material product candidates under development or otherwise
advise. In addition,
         we note your disclosure here that, [t]wo Phase 3 studies are currently
ongoing with
         enrollment expected to be completed in the second half of 2022."
Please revise to discuss
         the trial design and primary and secondary endpoints of the ongoing
studies or otherwise
         advise.

the aggregate
         potential milestone payments and quantify the amount paid to date
under such agreements.

registration statement or
         provide your analysis as to why you do not believe filing is required.
Refer to Item 601 of
         Regulation S-K for guidance.
