EMA одобрила статус орфанного препарата для лечения генерализованного пустулезного псориаза

WASHINGTON, July 16, 2026 /PRNewswire/ -- Vanda Pharmaceuticals Inc. (Vanda) (Nasdaq: VNDA) today announced that the Committee for Orphan Medicinal Products at the European Medicines Agency (EMA) has adopted a positive opinion recommending orphan drug designation for imsidolimab, the company's investigational medicinal product, a high-affinity humanized immunoglobulin G4 (IgG4) monoclonal antibody, for the treatment of generalized pustular psoriasis (GPP). This marks the first time the EMA has granted orphan drug designation recognition for a drug to treat GPP in the European Union (EU). GPP is a severe, chronic, and potentially life-threatening inflammatory skin disease, genetically and clinically distinct from plaque psoriasis, driven by dysregulation in the interleukin-36 (IL-36) signaling pathway.1 It is characterized by widespread pustular eruptions, systemic inflammation, and serious complications that can lead to increased mortality.234 Imsidolimab inhibits IL-36 receptor signaling, addressing the deficiency in the endogenous IL-36 receptor antagonist commonly observed in patients with GPP. The EMA's orphan drug designation is granted to medicines intended for the treatment of life-threatening or chronically debilitating rare conditions affecting fewer than 5 in 10,000 people in the EU. Benefits include protocol assistance, reduced regulatory fees, and market exclusivity provisions in the EU following approval. "The EMA's positive opinion is a significant milestone that reinforces the highly encouraging clinical data supporting the imsidolimab program and formally recognizes GPP as an orphan disease in the EU for the first time," said Dr. Mihael H. Polymeropoulos, "This designation highlights the urgent unmet medical need in GPP and brings us one step closer to delivering a meaningful new therapy to patients in the EU." This designation follows similar regulatory recognitions in the United States and Japan. Additionally, the imsidolimab Biologics License Application (BLA) for GPP is currently under review by the FDA with a target action date of December 12, 2026. References - Smieszek, S. et al.
