Barzolvolimab Shows Sustained Efficacy, Disease Modification in Phase 2 Urticaria Data
Summary
Celldex Therapeutics presented additional positive Phase 2 data for its lead asset, barzolvolimab, in Chronic Spontaneous Urticaria (CSU), Cold Urticaria (ColdU), and Symptomatic Dermographism (SD) at the AAAAI 2026 meeting. The data highlighted sustained off-treatment efficacy in CSU patients, with up to 41% achieving complete response seven months after their last dose, suggesting potential disease modification. This is a significant finding, as it implies a lasting impact beyond active treatment. This positive update follows the company's recent announcement of completed Phase 3 enrollment for barzolvolimab in CSU, as noted in the recent 10-K filing. The new data further strengthens barzolvolimab's profile as a potential 'first-in-class and best-in-disease' treatment, significantly de-risking the asset and enhancing its commercial prospects. Investors will now closely monitor the progress and eventual readout of the ongoing Phase 3 CSU trials.
