January Page 2 12, 2022 Page 2 FirstName LastName 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. Business of MoonLake, page 183 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.
