Prospectus Summary
Overview, page 1

2.       Please provide us with the basis for your claims that you have more
than a decade of
         leadership in translational bioinformatics and that you have an
established track record of
         generating insights into drug mechanisms of action and patient
treatment responses.
Our Wholly Owned Pipeline, page 2

3.       Please revise your pipeline table to combine the lead optimization
column with the
         discovery column. A textual discussion of the program is a more
appropriate place to
         make distinctions regarding different segments within a particular
phase. With the
         exception of IMM-1-104, it appears that all of your product candidates
are in the
         discovery phase. Given the early stage of development of these
programs, please explain
         why each program is sufficiently material to your business to warrant
inclusion in your
         pipeline table
Dual-MEK Program, page 4

4.       We note statements in the Summary and Business sections regarding the
performance of
         your product candidates. For example, we note statements that you have
observed
         therapeutic activity with improved tolerability of IMM-1-104 in
preclinical studies as
         compared to current FDA-approved drugs and similar statements. Please
revise the first
         paragraph on page 4 and similar statements throughout the prospectus
to revise all
         performance claims so that the basis for each statement is clear.
Safety and efficacy
         determinations are the exclusive authority of the FDA or comparable
foreign regulators.
         You may provide a summary of the data that you used to draw these
conclusions, but not
         the conclusions or predictions that the product candidates are safe or
effective.
Our Strategy, page 5

5.       We note your disclosure here and elsewhere in the prospectus
referencing your plans to
         "rapidly advance" the development of IMM-1-104. Please revise this
disclosure and
         similar disclosure throughout the prospectus to remove any implication
that you will be
         successful in developing your product candidates in a rapid or
accelerated manner as such
         statements are speculative.
6.       We note your statements here and in the Business section claiming that
your platform
         allows you to leverage human biological data in new and creative ways
which provide
         counterintuitive insights that are not constrained by inherent
limitations of conventional
         approaches or prevailing scientific views. However, translational
bioinformatics appears
         to be a growing field with numerous researchers and participants.
Please revise your
         disclosure to explain why your approach in particular is
counterintuitive and why you are
         able to leverage data in ways that others cannot.

7.       We note that you identify certain entities as investors in your
company here and on page
         98. However, certain of these entities do not appear to be among your
principal
         stockholders as disclosed on page 153. If material, please expand your
disclosure to
         describe the nature of each such entity's investment in you and
explain to us why
         including this information is appropriate. Please also explain in the
response your plans to
         update investors about any changes these entities make with respect to
their investments in
         your company.
Summary Risk Factors, page 5

8.       Please revise to add the risk that your approach to the discovery and
development of
         product candidates is unproven, and you may not be successful in your
efforts to use and
         expand your DCT platform to build a pipeline of product candidates
with commercial
         value.
Implications of Being an Emerging Growth Company and a Smaller Reporting
Company, page 7

9.       Please supplementally 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.
Use of Proceeds, page 75

10.      Please update the second bullet in Use of Proceeds, when possible, to
disclose how far in
         the development of these programs you estimate that the proceeds from
this offering will
         allow you to reach, including how many additional programs and how
many of your
         current programs you will be able to pursue and for how many programs
you estimate that
         you will be able to begin or complete IND-enabling studies.
Critical Accounting Policies
Equity-based Compensation, page 91

11.      It appears from your Outstanding Equity Awards table on page 144 that
you did not grant
         any options or other equity awards to the three named executive
officers (NEOs) during
         2020. Please confirm for us that none of the equity-based awards
granted in 2020 as
         presented in the table on page 92 were granted to NEOs or revise your
disclosure
         accordingly.
12.      Once you have an estimated offering price or range, please explain to
us how you
         determined the fair value of the common stock underlying your equity
issuances and the
         reasons for any differences between the recent valuations of your
common stock leading
         up to the initial public offering and the estimated offering price.
This information will help
         facilitate our review of your accounting for equity issuances
including stock compensation

         response.
Business, page 94

13.      We note your disclosure on page 49 that you own pending patent
applications in the
         United States related to your platform technologies and pending patent
applications
         related to your product candidates. Please revise your Business
section to include a
         discussion of your intellectual property coverage, including the
specific products, product
         groups and technologies to which the patent applications relate, the
type of patent
         protection you are seeking, the applicable jurisdictions and the
potential patent expiration
         dates.
Our Bioinformatics Approach, page 99

14.      We note your statement that your approach has already yielded programs
that have
         exhibited preclinical activity against a broad range of clinically
challenging solid tumors
         and are advancing towards the clinic. Please revise your disclosure to
clarify that the
         majority of your product candidates have yet to advance to
IND-enabling studies.
Our Differentiated Approach to Tackling Some the Most Challenging Cancers, page

15.      Please provide the basis for your claim that your insights derived
from your translational
         bioinformatics platform have "substantiated" your belief that
leveraging signaling
         dynamics against tumor addiction will result in better drugs. This
statement appears to be
         premature given the current stage of development of your product
candidates.
Trifecta-MEK Program, page 110

16.      We note your statement that you are developing "potentially
first-in-class" therapies that
         are designed to uniquely engage MEK. Given your current stage of
development, it
         appears to be premature to make this claim. Please revise your
disclosure to remove this
         statement.

17.      When available, please revise this section to describe the material
terms of your new
         employment agreements with your named executive officers and file the
agreements as
