   2.                                                   We note your disclosure
on page 29 that you acquired ESK-001 via a stock purchase of
                                                        FronThera U.S.

                                                        Pharmaceuticals LLC,
and your disclosure on page 88 that, under the stock purchase
                                                        agreement, you are
obligated to pay contingent consideration of up to $120.0 million
                                                        based on the
achievement of specified clinical and commercialization milestones. If any of
                                                        the material product
candidates you are developing were acquired in this transaction,
 Martin Babler
Alumis Inc.

Page 2
         please include appropriate disclosure in your prospectus summary and
include disclosure
         regarding these potential milestone payments. Please also tell us why
it would not be
         appropriate to file this stock purchase agreement as an exhibit to the
registration
         statement. Refer to Item 601(b)(10) of Regulation S-K.
Our Pipeline, page 2

3.       We note your statements in the first paragraph of this section and on
pages 4, 97, and 98
         regarding the opportunity to develop a "best-in-class" profile for
ESK-001. Given the
         development stage of your programs and length of the drug approval
process, it appears to
         be premature to speculate or imply that ESK-001 will be approved or
become best-in-class
         for any indication at this time. Please revise these statements and
any similar statements
         throughout.
4.       We note your statements that your clinical trial "data demonstrated
that ESK-001   s ability
         to maximally inhibit TYK2 translates to the achievement of high rates
of response   in
         patients, with response rates in the range observed with existing
biologic therapies" and
         that your Phase 2 STRIDE trial "met its primary endpoint, the
proportion of patients
         achieving a 75% improvement   at week 12 compared to placebo." To
balance the
         disclosure in your prospectus summary, please disclose any adverse
events observed in the
         Phase 2 STRIDE trial or include a cross reference to the relevant
disclosure in the
         "Business" section. In this regard, we note your disclosure of adverse
events in your Phase
         2 STRIDE trial and in your open label extension on pages 107, 108, and
110. Please also
         clarify what you mean by "maximally inhibit TYK2" since from the
figure on page 111 it
         does not appear that TYK2 is completely inhibited at the dose ranges
shown in that figure.
5.       We note your disclosure on pages 3 and 96 that "A-005 has demonstrated
protective
         effects in multiple in vivo disease models of neuroinflammation."
Please briefly describe
         the preclinical studies and the results thereof that led to this
conclusion. If
         the experimental autoimmune encephalitis (EAE) model is the model that
supports this
         disclosure, please make that clear.
6.       We note your disclosure on page 114 that you are evaluating ESK-001 in
an ongoing
         Phase 2a clinical trial in patients with Uveitis. Since it appears
that the related arrow in
         your pipeline table is half-way through the Phase 2 portion of the
row, please tell us if it
         would be appropriate to shorten the arrow in that row to reflect that
you are still in Phase
         2a of the trial. Also clarify if you anticipate conducting a Phase 2b
trial prior to
         proceeding to a Phase 3 trial for this indication.
7.     We note your disclosure on page 116 that you intend to pursue MS as your
initial

       indication for A-005. If you have not definitively selected MS as your
targeted indication

Our Strategy, page 4

8.       We note your description here and on page 98 that A-005 is a
"potential first-in-class
         allosteric TYK2 inhibitor designed to penetrate the CNS to treat
neuroinflammation."
         Please remove the references to "first-in-class" or explain why you
believe A-005 is a
         "potential first-in-class" allosteric TYK2 inhibitor, including, for
example, whether you
         are aware of any competing product candidates that are further along
in the development
         process.
Use of Proceeds, page 73

9.       We note that you intend to use the proceeds from this offering for
multiple purposes,
         including "to fund clinical development and related studies for
product candidates as well
         as [y]our activities in preparation for such clinical development." We
also note your
         disclosure that the proceeds "will not be sufficient for [you] to fund
[y]our programs
         through regulatory approval and commercialization" and that you "will
need to raise
         substantial additional capital in order to do so." Please revise your
disclosures in this
         section to:
             identify how you intend to allocate the proceeds among the various
intended
              purposes;
             clarify which products or programs you currently intend to fund
with the proceeds
              from this offering;
             disclose how far into the development process you anticipate such
proceeds will
              enable you to reach; and
             state the anticipated amount of other funds, if any, that may be
necessary to
              accomplish the specific purposes for which the proceeds are to be
obtained.

10.      We note your disclosure in the third paragraph that, prior to the
occurrence of certain
         timelines or events, you have an obligation to sell additional shares
of your Series C
         redeemable convertible preferred stock. Please revise your disclosure
to clarify whether
         the described obligations are eliminated after the earlier to occur of
the listed timelines or
         events or update your disclosure when appropriate to indicate how
these obligations have
         been satisfied.

11.      Once you have an estimated offering price range, please explain to us
the reasons for any
         differences between recent valuations of your common stock leading up
to the planned
         offering and the midpoint of your estimated offering price range. This
information will
         facilitate our review of your accounting for stock compensation.

Our Precision Approach and Capabilities, page 98

12.      We note your references to "[y]our precision data analytics platform"
throughout the
         prospectus. We further note your reference on page 98 to benefitting
from Foresite Labs
         data platform and your establishment of "a precision data analytics
platform" with
         Foresite Labs    capabilities as a foundation. Please clarify whether
you own or in-license
         the precision data analytics platform discussed throughout the
prospectus, and if in-
         licensed, please briefly describe the material terms of the license
agreement or other
         arrangement.
13.      Please explain the basis for your belief "that the application of
insights from [y]our
         internal efforts, combined with [y]our Foresite Labs collaboration,
may ultimately bring
         forth the most effective, paradigm-shifting medications by optimizing
[certain] design
         elements." In addition, explain what you mean by "paradigm-shifting."
To the extent
         material, please also address, in the risk factors section, the
potential risks that could arise
         in the event your collaboration with Foresite is terminated.
14.      At the bottom of page 99, you describe the figure at the top of page
100 as an illustration
         of the indications that you "are pursuing" for your TYK2 franchise.
Please revise this
         sentence to clarify the indications you are currently pursuing and
which ones are potential
         additional indications of interest.
Right Target, page 99

15.      Please clarify if the proprietary genetic database you refer to was
developed by you or in-
         licensed or acquired. Please also indicate the basis for your belief
that drugs with
         indications supported by human genetics have twice the likelihood of
success in Phase 2
         and Phase 3 clinical development.
Right Molecule, page 99

16.      Please clarify if you designed ESK-001 and A-005 using the methods
described in the
         first bullet point of this section.
Role of TYK2 in Immunology, page 101

17.      In the second bullet point at the top of page 3, you state you design
your molecules to
         achieve maximal target engagement and a "safe pharmacological
profile." In the last
         sentence on page 101, you state, "this TYK2 variant does not appear to
significantly
         increase susceptibility to serious infections, suggesting that TYK2
inhibition may be
         associated with an optimal balance between efficacy and safety." We
note similar
         disclosures on page 111 that your "STRIDE Phase 2 clinical trial and
open label extension
         trial in PsO demonstrated that ESK-001 at a dose of 40 mg BID was well
tolerated and
         highly efficacious" and on page 117 that "A-005 can effectively
inhibit TYK2 microglial
         responses in primary microglia derived from human induced pluripotent

         stem cell   ." Please revise your prospectus to remove any statements
regarding efficacy
         or safety determinations as such determinations are solely within the
authority of the
         FDA.
Preliminary Results from the Ongoing OLE Trial, page 108

18.      Please disclose whether the ongoing OLE trial is powered for
statistical significance, and
         if so, disclose the p-values for the preliminary results discussed in
this section.
19.      We note your disclosure on page 110 that there have been five serious
adverse events in
         the OLE trial, including two that you have assessed to be possibly
related to study drug.
         Similar to your disclosure in the risk factor on page 18, please
disclose here the nature of
         these serious adverse events.
Proposed Phase 3 Clinical Trials of ESK-001 in PsO, page 112

20.      Please disclose the regulatory jurisdictions where you intend to
conduct your proposed
         Phase 3 clinical trials for ESK-001 in PsO. We also note your
disclosure that ESK-001 has
         the potential to be a best-in-class TYK2 inhibitor and that, if
approved, ESK-001 would
         compete with several currently approved or late-stage oral clinical
therapeutics, including
         Sotyktu. Given that disclosure, please clarify your reasons for using
Otezla as a
         comparator and clarify how you would substantiate your intended
best-in-class claims
         with results from these trials.
Ongoing Phase 2b LUMUS trial of ESK-001 in SLE, page 113

21.      Please disclose the regulatory jurisdictions where you are conducting
your Phase 2b
         clinical trial. We also note your disclosure that this trial is
designed to potentially serve as
         the first of two pivotal trials. Please clarify if this means that you
might be able to have the
         Phase 2b trial serve as the basis for seeking regulatory approval or
if you would need to
         conduct Phase 3 trials.
A-005: Our CNS Penetrant Allosteric TYK2 Inhibitor, page 116

22.      We note your disclosure here and on page 119 that you have initiated a
"multi-cohort
         investigation to assess   orally-administered A-005." Please clarify
whether this is a
         different study than the Phase 1 study of A-005 that you reference on
pages 1, 3, 79, 95,
         and 96. In addition, describe the clinical protocol for the Phase 1
study and, if different,
         for this investigation, including any primary and secondary endpoints.

candidates, if
         approved, in key markets in the United States, the European Union, and
APAC   ." We
         also note from page 112 that you have received and incorporated
feedback from the FDA
         and the CHMP in Europe in your proposed Phase 3 program in PsO and
that you have
         requested regulatory feedback from the PMDA in Japan. However, the
government
         regulation discussion in this section only substantively addresses the
United States. Please

government regulations
         regarding Europe and Japan.
Management
Composition of Our Board of Directors, page 137

27.      We note your disclosure that you have one vacancy on your board of
directors and that the
         vacancy is a position that, under the terms of a voting agreement you
entered into with
         certain of your stockholders, is to be filled, upon mutual agreement
of your board of
         directors, by a person who is not otherwise your employee or
affiliate. We further note
         your disclosure that the voting agreement will terminate upon closing

         Please revise your disclosure to clarify your intent with respect to
the vacancy, including
         whether you intend to fill the vacancy pursuant to the terms of the
voting agreement prior
         to its termination or otherwise pursuant to the terms of your
constituent documents after
         closing of this offering.

Principal Stockholders, page 162

29.      In the fourth paragraph, you state that the percentage ownership of a
person is calculated
         by dividing the number of shares such person holds by a sum that
includes the number of
         shares of non-voting common stock that the person has the right to
convert to common
         stock within 60 days. Please revise the footnotes to the table,
including footnote 10, to
         clarify the number of shares of non-voting common stock, if any, held
by each listed
         stockholder.
30.      In footnotes 4 and 5 to the table, please clarify whether the trustees
have sole or shared
         voting and dispositive power over the applicable shares referenced
therein.
Common Stock and Non-Voting Common Stock, page 165

31.      We note that your amended and restated certificate of incorporation
will authorize two
         classes of common stock. Please describe the differences, if any, in
the information that
         the holders of each class will receive, and the timing of receiving
such information, as
         compared to the information provided to holders of the other class.
32.      We note that holders of your non-voting common stock will have the
right to convert each
         share of non-voting common stock into one share of common stock at the
respective
         holder   s election, subject to certain restrictions. Please also
disclose whether there are any
         automatic or mandatory conversion provisions associated with the
non-voting common
         stock.
Voting Rights, page 165

33.      You state that your non-voting common stock is not entitled to any
votes per share, except
         as required by law, and you identify some instances in which holders
of non-voting
         common stock would have a right to vote. Please revise your disclosure
to clarify, in
         instances where non-voting common stockholders have a right to vote,
the number of
         votes to which each share of non-voting common stock is entitled and
whether the non-
         voting common stockholders would vote separately or together as a
single class with the
         common stockholders. For the matters that require the approval of the
non-voting
         common stock described in clause (iii)(A) and (B), please include
appropriate risk factor
         disclosure, and revise here to describe the Fundamental Transactions

35.      We note your disclosure here and in other parts of the prospectus
regarding your directed
         share program. Please revise your prospectus to clarify, where
appropriate, including in
         the risk factors and in the "Principal Stockholders" section, that:
             your directors, officers, employees, business associates, and
related persons may
              participate in this program, resulting in further concentration
of beneficial ownership
              and control than is reflected in the prospectus; and
             the beneficial ownership and control disclosures presented in the
prospectus assume
              that no shares of common stock are purchased by your directors,
officers, employees,
              business associates, and related persons pursuant to the directed
share program.
         In addition, please expand your disclosure to address the process that
prospective

which you will
         communicate with prospective participants about the program, when and
how you will
         determine the allocation for the program, whether such allocation will
change depending
         on the interest level of potential participants, and any other
material features of the
