   1.                                                   We note that you intend
to apply for listing of Mural's ordinary shares on the Nasdaq
                                                        Global Market in
connection with the distribution. Please revise the cover page and the
                                                        Q&A as follows, and
make conforming revisions throughout the Information Statement
                                                        where appropriate:
                                                            State, if true,
that no assurance can be given that your listing application will be
                                                            approved.
                                                            State whether the
distribution is contingent upon final approval of your NASDAQ
                                                            listing.
                                                            Revise to clarify,

              the distribution may be waived by Alkermes in its sole discretion
as you have on page
              165.
Questions and Answers About the Separation and Distribution, page 3

2.       Please tell us when you expect to determine the distribution ratio.
Please explain why you
         indicate that the distribution will be pro rata despite your plan to
aggregate fractional
         shares into whole shares, sell the whole shares into the open market
and distribute the
         aggregate proceeds.
Information Statement Summary, page 11

3.       We note that your auditors have issued a going concern opinion
regarding your
         operations. Please revise your disclosure throughout the Information
Statement as
         follows:
             Expand and balance your Summary disclosure by including discussion
regarding
              Mural's recurring operating losses, the expectation of continuing
operating losses for
              the foreseeable future, the need to raise additional capital to
finance your future
              operations, your agreements and obligations under the Tax Matters
Agreement with
              Alkermes which may limit your ability to issue ordinary shares to
raise capital during
              the four-year period beginning two years before and ending two
years after the
              distribution, your reliance on an initial cash contribution from
Alkermes for funding
              following the separation until you are able to access capital
markets and other sources
              of capital, and the auditor's going concern opinion.
             Disclose in both the Summary Risk Factors and Risk Factors that
your ability to
              continue as a going concern is contingent upon the receipt of
funding from Alkermes
              through the date of separation that will be contributed to Mural
immediately prior to
              or in connection with the separation to cover Mural   s capital
needs following the
              separation until it is able to access capital markets and other
sources of capital, as you
              have on page 97. Additionally, explain how this reliance on an
initial contribution
              from Alkeremes relates to the Tax Matters Agreement, which you
state may limit
              Mural's ability to access capital on page 72. Disclose that if
you cannot continue as a
              viable entity, your stockholders may lose some or all of their
investment in your
              company.
4.       Please revise the description of your ongoing trials to identify the
trial phase in the text
         and define the term "registrational studies" and explain why your
studies are "potentially"
         registrational. Your discussion should clarify the factors that will
determine whether they
         are registrational and who will make such determination.

         nemvaleukin in combination with pembrolizumab for the treatment of
PROC.
         Additionally, explicitly state that fast track designation does not
guarantee an accelerated
         review by the FDA. Provide similar disclosure on page 121 with respect
to the
         accelerated approval pathway.
6.       We note that your disclosures throughout this section, and a similar
section on page 104,
         reference terms such as "durable and deepening responses," "complete
responses," "partial
         responses," "confirmed" responses, "disease control rate," "overall
response rate," and
         "stable disease." Please revise your discussion to describe the
results of your clinical trials
         using objective terminology based on the clinical trial end points.
7.       With reference to the following non-exhaustive list of illustrative
examples, please
         remove these and all other statements throughout the Information
Statement that state or
         imply that your product candidates are safe or effective, as these
determinations are solely
         within the authority of the U.S. Food and Drug Administration and
comparable regulatory
         bodies:
             "Our data has shown anti-tumor activity with nemvaleukin as a
monotherapy in
              cancers for which high dose rhIL had proven efficacy, such as
melanoma and renal
              cell carcinoma." (page 12);
             Your statement of belief that features of nemvaleukin "may widen
its potential
              therapeutic window compared to that of high-dose rhIL02, in terms
of both safety and
              efficacy" (page 111);
             References to your belief that nemvaleukin's molecular design may
provide benefits
              over other IL-2 treatment options that may confer "enhanced
efficacy" (table on page
              112);
             Reference to the "initial efficacy signals" observed with
nemvaleukin in combination
              with pembrolizumab in patients with PROC in the ARTISTRY-1
              study (page 121).
         You should include a discussion of your clinical trials that includes
a description of the
         trials, the number of participants, the trial endpoints, serious
advers events, and whether
         the results were statistically significant, including p values.
Risk Factors , page 21

8.       We note your discussion of the conditions to the distribution on page
165. Given that the
         Nasdaq listing condition pertaining to Mural's ordinary shares appears
to be waivable,
         please include a risk factor reflecting that that this condition may
be waived. Describe the
         consequences of not securing Nasdaq listing approval prior to the
distribution.
9.       With reference to your disclsoure on page 184, please describe in an
appropriate risk
         factor the risks related to:
             Your quorum requirements; and
             The allowable methods for which polls are to be taken at corporate
meetings and the
              manner in which the votes are to be counted, including any
material distinctions
              between such methods.

         jurisdiction to determine the outcome of certain litigation, including
derivative actions
             Please disclose in your Risk Factors and Description of Share
Capital section whether
              this provision applies to actions arising under the Exchange Act
and the Securities
              Act. If so, please address the uncertainty as to whether a court
would enforce such
              provision, and state that shareholders will not be deemed to have
waived the
              company's compliance with federal securities laws and the rules
and regulations
              thereunder. If the provision does not apply to actions arising
under the Exchange Act
              and the Securities Act, please also ensure that the disclosure in
your Risk Factors and
              Description of Share Capital sections and the exclusive forum
provision in your
              Articles of Association state this clearly, or confirm that you
will inform investors in
              future filings that the provision does not apply to any actions
arising under the
              Securities Act or Exchange Act.
             Additionally, please expand this risk factor to highlight the
material impact and risks
              to shareholders related to this exclusive forum provision. Such
risks may include,
              but are not limited to, increased costs to bring a claim and that
these provisions can

in a judicial forum that

20.      With respect to your description of cell expansion analyses from your
ARTISTRY-1
         clinical trial, you indicate in the narrative and graphic on page 112
that nemvaleukin
         showed similar or greater levels of cancer fighting cell expansion
than observed
         historically with high-dose rhIL-2, with lower levels of Treg
expansion. Please remove all
         statements indicating that treatment candidates that are not FDA
approved are as effective
         or superior to approved immunotherapies. You may present objective
result of clinical
         trials but such results should not be compared to alternative
treatment products unless

      federal income tax and Irish tax purposes to Alkermes    shareholders. We
also note that
      the disclosed tax consequences in this section assume that the
Distribution, together with

in this section, and
      elsewhere as appropriate, to remove language stating that "generally"
certain tax
      consequences will apply and express a firm opinion for each material tax
consequence. If
      there is uncertainty regarding the tax treatment of the transaction,
counsel may issue a
         should    or    more likely than not    opinion to make clear that the
opinion is subject to a
      degree of uncertainty and explain why it cannot give a firm opinion.
