   1.                                                   We note your statement
that industry publications and third-party research, surveys and
                                                        studies generally
indicate that their information has been obtained from sources believed
                                                        to be reliable,
although they do not guarantee the accuracy or completeness of such
                                                        information. These
statements appear to imply a disclaimer of responsibility for this
                                                        information in the
registration statement. Please either delete this statement or specifically
                                                        state that you are
liable for the information related to the market and industry data.

Our Company, page 1

2.       Please include an organization and ownership chart to explain the
structure of your
         company and its subsidiaries, including your various ownership
percentages. Please also
         include any variable interest entities. In addition, your ownership in
each of these
         subsidiaries or variable interest entities should be clarified
throughout your registration
         statement. For example, revise references to your subsidiaries to use
the partially/wholly
         owned qualifiers.
Our Process, page 2

3.       We note your disclosure in your graphic on page 2 that one of your key
selection criteria
         is that your product candidates have the potential to be
first-in-class    and throughout the
         registration statement you make statements that your "portfolio
includes a number of
         compounds that have the potential to be developed as first-in-class
therapeutics." The term
         "first-in-class" suggests that your product candidates are effective
and likely to be
         approved. Given the early stages of development for each of your
candidates, the term
         appears speculative. Please revise to delete these references
throughout your registration
         statement. We will not object to statements that you are developing
the candidates to
         address an unmet need.
Our Enabling Technologies, page 3

4.       We note your statement here and elsewhere in your draft offering
statement that your
         digital therapeutics platform may "improve patient outcomes" and "has
the potential to
         both secure stronger intellectual property, or IP, protection and
increase the probability of
         success for [y]our programs." Given the current stage of your product
candidates, please
         remove your statement that your digital therapeutics platform can
"improve patient
         outcomes" and "increase the probability of success of [y]our
programs," or otherwise
         provide your basis for this claim. In addition, please update your
disclosure to
         explain how your digital therapeutics platform works as well as
clarify what makes
         it novel or unique when compared to existing technology.
Our Pipeline, page 3

5.       With respect to the "Total Programs and Enabling Technologies Per Year
Since
         Inception" chart, we note it indicates you currently have 13 programs
and technologies in
         development. However, you only depict six product candidates in the
pipeline table.
         Additionally, we note you have four other programs identified on pages
147 and 148.
         To the extent that the other 7 programs and technologies are not
material, please move the
         chart and references to these programs and technologies to the
Business section where
         they can be put in proper context.
6.       Additionally, with respect to the total programs and technologies
chart, please clarify the
         following:

                Whether the programs attributed to each year, include the
number of continuing
              programs from the prior year;
                Whether there were any programs terminated during the
timeframe;
                What minimum criteria was required for inclusion in the chart;
and
                Which programs were acquired and which were created de novo.
7.       Please disclose which of your product candidates were developed using
each of
         EntheogeniX Biosciences and Introspect Digital Therapeutics.
Additionally, clarify
         whether these programs were acquired to developed de novo.
8.       We note that you do not hold a majority interest in gaba or
Neuronasal. Please explain the
         extent to which you control the product candidate development and
clarify your financial
         interest in the product candidate, such as rights to commercialization
rights, regulatory or
         development milestone payments, etc.
Our Emerging Clinical and Preclinical Programs, page 4

9.       We note statements throughout your that imply efficacy. For example
only, we note the
         following statements you make regarding your product candidates:
"[PCN-101]
         demonstrated a rapid and durable response" and "[DMX-102] demonstrated
rapid and
         sustained efficacy in treating opioid use disorder." Please revise
your disclosure
         throughout your prospectus to revise these and similar statements to
eliminate conclusions
         or predictions that your product candidates are effective as
determinations of efficacy are
         solely within the authority of the FDA or equivalent foreign
regulator. You may provide a
         summary of the objective data that you used to draw these conclusions,
and such
         discussion is more appropriate in the Business section where full and
proper context can
         be provided.

10.      Please provide us with copies of all written communications, as

whether or not they
         retain copies of the communications.
Collaborative relationships with third parties could cause us to expend
significant resources and
incur substantial business risk with..., page 53

11.      In addition to your cross reference to Note 3 of you financial
statements, please quantify
         the potential aggregate milestones payments outstanding that you may
be required to
         make to maintain your current ownership percentages in your various
subsidiaries. In
         addition, please expand your disclosure here, or in a separate risk
factor, to explain how
         your majority owned operating subsidiaries could seek and accept
capital from third party
         investors, thereby diluting your ownership and control over such
entities, without your
         consent.

             aggregate potential milestone payments;
             royalty provisions, quantified within a ten point range; and
             term and termination provisions.

15.      Throughout this section you disclose third-party studies of certain
variations or different
         formulations of your various product candidates. Please revise to
clearify whether the
         prior trials were conducted on your actual product candidate versus a
similar product
         candidate or different formulation.
16.      In some instances you compare the results to other products. Please
clarify whether the
         prior trials involved head to head studies. If they did not, remove
the disclosure
         comparing the product candidate to another product.

         the treatment of neuropathic pain. Please advise on how the
"pro-cognitive effects" were
         measured or observed and explain whether the studies were powered to
         show statistical significance.
