Celldex Presents Long-Term Barzolvolimab Results Demonstrating Sustained Off-Treatment Improvement in Angioedema in Patients with CSU at the European Academy of Allergy and Clinical Immunology Annual Meeting

HAMPTON, N.J., June 14, 2026 (GLOBE NEWSWIRE) -- Celldex (NASDAQ:CLDX) announced today the presentation of long-term results from the Phase 2 study of barzolvolimab in a flash talk session at the European Academy of Allergy and Clinical Immunology (EAACI) Annual Meeting in Istanbul, Türkiye. The data presented demonstrated that barzolvolimab treatment results in rapid, significant, and durable improvements in angioedema in patients with chronic spontaneous urticaria (CSU) refractory to antihistamines. These results were sustained off-treatment, seven months after completion of barzolvolimab dosing (Week 76). The data continue to demonstrate barzolvolimab’s potential to shift the goal of CSU treatment from symptom control to disease modification and further support the ongoing Phase 3 trials of barzolvolimab in CSU.
