In two pivotal Phase 3 placebo-controlled trials Regeneron Pharmaceuticals’ (REGN) and Sanofi’s (SNY) drug, Dupixent® (dupilumab), demonstrated a significant reduction in nasal polyp size, nasal congestion’s severity and the need for systemic corticosteroids and/or surgery.

Both trials were evaluating Dupixent® (dupilumab) in adults with inadequately-controlled chronic rhinosinusitis with nasal polyps (CRSwNP). They both met met all their primary and secondary endpoints.
