Vanda Antibody BLA for Pustular Psoriasis
Vanda Pharmaceuticals has filed a BLA for imsidolimab and its use in treating generalized pustular psoriasis, a rare and potentially fatal inflammatory skin disease with no broadly effective long-term therapies. The disorder is driven in many cases by mutations in the IL36RN gene that disrupt the body’s natural inflammation regulation, causing sudden flares of widespread pustules, redness, fever and systemic illness that can require hospitalization. The company has requested priority review, which, if granted, would provide a review decision in mid-2026.
The submission for the investigational IL-36 receptor–blocking monoclonal antibody is based on data from two global Phase 3 trials, GEMINI-1 and GEMINI-2. In GEMINI-1, a 45-patient randomized study, a single intravenous infusion of imsidolimab led to rapid clinical improvement, according to the company. At four weeks, 53% of patients receiving imsidolimab achieved clear or almost clear skin, compared with 13% of patients on placebo.
