MoonLake Securities Suit Advances in SDNY as Firms Urge Investors to Seek Lead Role by Dec. 15
The complaint alleges MoonLake overstated sonelokimab’s Nanobody benefits, misleading investors about its clinical prospects.
Overview
- Peters v. MoonLake Immunotherapeutics, No. 1:25-cv-08612, is pending in the Southern District of New York asserting claims under Sections 10(b) and 20(a).
- Investor notices set a December 15, 2025 deadline to move for lead-plaintiff status, with outreach from Bleichmar Fonti & Auld, Rosen, Robbins Geller, Glancy Prongay & Murray, and the Law Offices of Howard G. Smith.
- Plaintiffs allege MoonLake misrepresented sonelokimab’s differentiation despite shared IL‑17A/IL‑17F targets with UCB’s BIMZELX and touted tissue penetration that did not translate to superior efficacy.
- MoonLake reported on September 28, 2025 that Phase 3 VELA week‑16 results were disappointing, including VELA‑2 missing its primary endpoint, and the stock closed at $6.24 on September 29 after a nearly 90% decline.
- No class has been certified, and investors are not represented by court‑appointed counsel unless and until a lead plaintiff is appointed.
