A Phase 3 trial of Dupixent (dupilumab) in patients with chronic spontaneous urticaria has failed to meet its primary endpoints and is being stopped early, Sanofi SA announced on 18 February. Dupixent is a widely prescribed medicine for asthma and atopic dermatitis and is being investigated for a possible new indication in urticaria, a chronic inflammatory skin disease characterised by the sudden onset of hives.
