         comments:

                We note your disclosure that you risk-adjusted your cash flows
by multiplying the
              non-adjusted cash flows with the estimated probability of such
cash flows occurring,
              and such probabilities were based on MoonLake management's
internal estimates and
              assumed an 81% probability for successful completion of Phase 2
studies and an 81%
              probability for successful completion of Phase 3 studies
following positive Phase 2
              data. Please revise to disclose how MoonLake management arrived
at these
              probabilities and determined that they were reasonable, including
whether the
              probabilities are consistent with the industry average for
successful completion of
              these phases and explain any differences between MoonLake and the
industry
              average. Please also revise to discuss the risk that the assumed
probabilities of
              successful completion may be unrealistic given the
unpredictability of drug
              development.
                It appears that MoonLake applied the same regulatory success
rate for SLK in each of
              the four indications. If that is true, please revise to explain
why.
                We note that MoonLake assumed a commercial launch of SLK in
2026 for all four
              indications. Please revise to disclose if the assumption was
limited to commercial
              launch in the U.S. If not, please disclose the other
jurisdictions and the assumed
              regulatory approval date for each of the four indications in
those jurisdictions.
                We note that Helix compared MoonLake   s forecasts against
published ranges for
              disease prevalence and made its own assumptions. Please disclose
the sources of
              those published ranges, Helix's assumptions on disease prevalence
for each of the
              four indications, how Helix arrived at those assumptions and how
Helix determined
              that those assumptions were reasonable.
                Please provide an estimated net income (loss) amount.

4.       We note your revisions in response to prior comment 14. Please revise
your disclosure to
         remove the references to "clinical effect" on page 183 and "clinical
benefit" on pages 53,
         138, 183, and 212. Safety and efficacy are determinations that are
solely within the
         authority of the U.S. Food and Drug Administration (FDA) or similar
foreign regulators.
         You may present clinical trial end points and objective data resulting
from trials without
         concluding efficacy. Please revise these and similar statements here
and throughout the
         document.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.
