Before Sept. 29, 2025, MoonLake expressed confidence to investors in sonelokimab’s trial designs, encouraged the belief that the studies could show at least a 20% difference between the sonelokimab group and patients given a placebo, and has assured investors that “we really have a drug here that can become the gold standard and obviously that will facilitate any winning that we do with sonelokimab in HS.” Investors’ expectations were dashed on Sep. 29, 2025, when MoonLake announced that in its VELA-2 trial “intercurrent events in the higher-than-expected placebo arm precluded the study from achieving statistical significance in the week 16 primary endpoint using the composite strategy (HiSCR75, delta to placebo of 9%[.]” On this news, the price of MoonLake shares cratered $55.75 (-90%) that day, with one analyst reportedly writing in a note to investors that the results “’arguably fall[] into the worst case outcome.’” “We’re focused on investors’ losses and whether MoonLake may have misled investors about the VELA-2 design and planning for potential intercurrent events while claiming that sonelokimab could become a ‘gold standard’,” said Reed Kathrein, the Hagens Berman partner leading the investigation.
