       Draft Registration Statement, Submitted May 7, 2021

       Summary, page 1

   1.                                                   We note your statement
on page 1 that CT1812 demonstrated a    favorable safety profile
                                                        and on page 2 that
CT1812 has continued to be generally safe. Please revise these and all
                                                        similar statements
throughout your prospectus that state or imply that your product
                                                        candidates are safe as
this determination is solely within the authority of the FDA and
                                                        comparable regulatory
bodies.
   2.                                                   On page 2 you state
that you intend to advance CT1812 directly into a Phase 2 clinical
                                                        trial in the second
half of 2021 for dry AMD. Please revise to state whether you have
                                                        consulted the FDA on
this approach, and if not, state that the FDA may disapprove of
                                                        your ability to rely on
prior studies, similar to your risk factor on page 19.

3.       Please tell us why you feel CT2168 and CT2074 are material enough to
be included in the
         pipeline table given their early stage, lack of discussion in the
prospectus and, with respect
         to CT2168, lack of a specific indication.
