MoonLake shares jump after AbbVie reports modest hidradenitis trial results

MoonLake Immunotherapeutics stock rose sharply after AbbVie disclosed Phase 3 data for its hidradenitis suppurativa drug lutikizumab, which showed an 8‑point advantage over placebo. MoonLake’s own sonelokimab had previously demonstrated a larger 14‑point gap in a similar endpoint. The company is awaiting FDA review of its biologic, submitted on Sept. 30, with a commercial launch targeted for the second half of 2027.

The stock surge reflects investor optimism that AbbVie’s modest results improve MoonLake’s competitive positioning (the company’s own data showed a larger efficacy gap). The pending FDA decision, expected around late November, will determine whether MoonLake can proceed to market in 2027 (the company says it expects a priority review).
