CHMP recommends approval of Dupixent® (dupilumab) for severe chronic rhinosinusitis with nasal polyposis
PARIS and TARRYTOWN, NY – September 20, 2019 – 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.
Dupixent is currently approved in the EU for patients 12 years and older as an add-on maintenance treatment for severe asthma with type 2 inflammation characterized by raised blood eosinophils and/or raised fractional exhaled nitric oxide (FeNO), who are inadequately controlled with high dose inhaled corticosteroid (ICS) plus another medicinal product for maintenance treatment. It is also approved in the EU for use in patients 12 years and older with moderate-to-severe atopic dermatitis who are candidates for systemic therapy.
Outside of the EU, Dupixent is approved for use in specific patients with moderate-to-severe atopic dermatitis and certain patients with asthma in a number of other countries around the world, including the U.S. and Japan. Dupixent is also approved in the U.S. for use with other medicines to treat CRSwNP in adults whose disease is not controlled.
Dupilumab Development Program
In addition to the currently approved indications, Sanofi and Regeneron are also studying dupilumab in a broad range of clinical development programs for diseases driven by allergic and other type 2 inflammation, including pediatric asthma (6 to 11 years of age, Phase 3), pediatric atopic dermatitis (6 months to 5 years of age, Phase 2/3 and 6 to 11 years of age, Phase 3), eosinophilic esophagitis (Phase 2/3), chronic obstructive pulmonary disease (Phase 3) and food and environmental allergies (Phase 2). Dupilumab is also being studied in combination with REGN3500 (SAR440340), which targets IL-33. These potential uses are investigational and the safety and efficacy have not been evaluated by any regulatory authority.
Dupilumab is being jointly developed by Sanofi and Regeneron under a global collaboration agreement.
