Alumis reports 54% PASI‑100 response in Phase 3 psoriasis trial and targets Q4 2026 NDA filing

Alumis Inc. presented new Phase 3 data for its oral TYK2 inhibitor envudeucitinib at a dermatology conference. The ONWARD3 extension showed 54% of patients achieved complete skin clearance (PASI 100) at Week 48, with over 80% maintaining clear scalp skin and substantial itch and quality‑of‑life improvements. The company confirmed its plan to submit a New Drug Application in the fourth quarter of 2026. The results were well tolerated with no new safety signals.

The company says the data support filing an NDA in Q4 2026, which could create upside potential for the stock if the FDA grants approval.
