CHMP Recommends Approval Of Dupixent (dupilumab) For Severe Chronic Rhinosinusitis With Nasal Polyposis

Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Sanofi today announced that the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion for Dupixent (dupilumab) in a third indication. The CHMP recommended Dupixent be approved as an add-on therapy with intranasal corticosteroids for the treatment of adults with severe chronic rhinosinusitis with nasal polyposis (CRSwNP) for whom therapy with systemic corticosteroids and/or surgery do not provide adequate disease control. If approved, Dupixent would be the first biologic medicine available in the European Union (EU) to treat these patients.

The positive CHMP opinion is based on two pivotal Phase 3 trials (the 24-week SINUS-24 and 52-week SINUS-52) that evaluated Dupixent 300 mg every two weeks plus standard-of-care intranasal corticosteroids compared to placebo plus intranasal corticosteroids. A final decision on the Dupixent application by the European Commission (EC) is expected in the coming months.

Dupixent is a fully-human monoclonal antibody that inhibits the signaling of the interleukin-4 (IL-4) and interleukin-13 (IL-13) proteins. Data from Dupixent clinical trials have shown that IL-4 and IL-13 are key drivers of the type 2 inflammation that plays a major role in CRSwNP, asthma and atopic dermatitis.

CRSwNP is a chronic disease of the upper airway that obstructs the sinuses and nasal passages. It can lead to persistent breathing difficulties, nasal congestion and discharge, reduced or loss of sense of smell and taste, and facial pressure or pain. For patients with severe CRSwNP, the current standard-of-care includes intermittent courses of systemic corticosteroids or sinonasal surgery, both of which are associated with disease recurrence. Many patients with CRSwNP have other type 2 inflammatory diseases like asthma, and these patients often have more severe asthma and are often more difficult to treat. Patients with CRSwNP and co-morbid asthma may have an increased risk of asthma attacks, high symptom burden and a substantial adverse impact on health-related quality of life. In the Dupixent CRSwNP trials, 59% of patients also had asthma. – PR Newswire
