Celldex Therapeutics IncPhase 2 study of barzolvolimab in prurigo nodularis failed to meet primary and key secondary endpoints, leading to discontinuation of the study.

Celldex reported that its Phase 2 study of barzolvolimab in prurigo nodularis did not meet the primary endpoint or key secondary endpoints. The randomized, double-blind, placebo-controlled trial evaluated two dose levels in patients with moderate to severe PN, but no meaningful improvement versus placebo was observed through week 24. Celldex will discontinue the Phase 2 study in PN, though barzolvolimab demonstrated a favorable safety and tolerability profile. The company noted that barzolvolimab has produced best-in-disease data in chronic spontaneous urticaria, symptomatic dermographism, and cold urticaria, and Phase 3 trials in CSU are expected to report data early this fall. Celldex shares fell 3.95% in after-hours trading to $34.25.
