Dupixent recommended for EU approval by the CHMP to treat patients with COPD

• Recommendation for adults with uncontrolled COPD with raised blood eosinophils based on data from two landmark Phase 3 trials demonstrating Dupixent significantly reduced exacerbations and improved lung function
• If approved, Dupixent would be the first-ever targeted therapy for COPD in the EU and the first new treatment approach for this disease in more than a decade

Paris and Tarrytown, N.Y. May 31, 2024. The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion recommending the approval of Dupixent (dupilumab) in the European Union (EU) as an add-on maintenance treatment in adults with uncontrolled chronic obstructive pulmonary disease (COPD) characterized by raised blood eosinophils. The European Commission is expected to announce a final decision on the Dupixent application in the coming months.

COPD is a respiratory disease that damages the lungs and causes progressive lung function decline and is the fourth leading cause of death worldwide. Symptoms include persistent cough, excessive mucus production and shortness of breath that may impair the ability to perform routine daily activities, which may lead to sleep disturbances, anxiety and depression. COPD is also associated with a significant health and economic burden due to recurrent acute exacerbations that require systemic corticosteroid treatment and/or lead to hospitalization. Smoking and exposure to noxious particles are key risk factors for COPD, but even individuals who quit smoking can still develop or continue having the disease. There have been no new treatment approaches approved for more than a decade.

The positive CHMP opinion is supported by data from the landmark BOREAS and NOTUS phase 3 studies that evaluated the efficacy and safety of Dupixent in adults with uncontrolled COPD with evidence of type 2 inflammation (i.e., blood eosinophils ≥300 cells per μL). All patients were on background maximal standard-of-care inhaled therapy (nearly all on triple therapy). The primary endpoint was met in both studies, showing Dupixent significantly reduced annualized moderate or severe acute COPD exacerbations by up to 34% compared to placebo. Dupixent rapidly and significantly improved lung function compared to placebo, with improvements sustained at 52 weeks. Additionally, Dupixent improved health-related quality of life at 52 weeks (statistically significant in BOREAS and nominally significant in NOTUS) as assessed by the St. George’s Respiratory Questionnaire (SGRQ).

Safety results in both studies were generally consistent with the known safety profile of Dupixent in its approved indications. Adverse events more commonly observed with Dupixent (≥5%) compared to placebo in either study were back pain, COVID-19, diarrhea, headache and nasopharyngitis. 

Submissions are also under review with regulatory authorities around the world, including in the U.S. and China. Earlier this year, the U.S. Food and Drug Administration (FDA) accepted for Priority Review the supplemental Biologics License Application for Dupixent as an add-on maintenance treatment in certain adult patients with uncontrolled COPD. The target action date is September 27, 2024.

The use of Dupixent in COPD is investigational and is not yet approved by global regulatory authorities.

About Sanofi and Regeneron’s COPD Clinical Research Program

Sanofi and Regeneron are motivated to transform the treatment paradigm of COPD by examining the role different types of inflammation play in the disease progression through the investigation of two potentially first-in-class biologics, Dupixent and itepekimab.

Dupixent inhibits the signaling of the interleukin-4 (IL-4) and interleukin-13 (IL-13) pathways and the program focuses on a specific population of people with evidence of type 2 inflammation. Itepekimab is a fully human monoclonal antibody that binds to and inhibits interleukin-33 (IL-33), an initiator and amplifier of broad inflammation in COPD.

Itepekimab is currently under clinical investigation, with two phase 3 studies currently enrolling, and its safety and efficacy have not been evaluated by any regulatory authority.

About Dupixent

Dupixent is a fully human monoclonal antibody that inhibits the signaling of the interleukin-4 (IL-4) and interleukin-13 (IL-13) pathways and is not an immunosuppressant. The Dupixent development program has shown significant clinical benefit and a decrease in type 2 inflammation in phase 3 studies, establishing that IL-4 and IL-13 are key and central drivers of the type 2 inflammation that plays a major role in multiple related and often co-morbid diseases.

Dupixent has received regulatory approvals in more than 60 countries in one or more indications including certain patients with atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), eosinophilic esophagitis (EoE), prurigo nodularis and chronic spontaneous urticaria (CSU) in different age populations. More than 850,000 patients are being treated with Dupixent globally.

Dupilumab Development Program

Dupilumab is being jointly developed by Sanofi and Regeneron under a global collaboration agreement. To date, dupilumab has been studied across more than 60 clinical studies involving more than 10,000 patients with various chronic diseases driven in part by type 2 inflammation.

In addition to the currently approved indications, Sanofi and Regeneron are studying dupilumab in a broad range of diseases driven by type 2 inflammation or other allergic processes in phase 3 studies, including chronic pruritus of unknown origin, chronic obstructive pulmonary disease with evidence of type 2 inflammation and bullous pemphigoid. These potential uses of dupilumab are currently under clinical investigation, and the safety and efficacy in these conditions have not been fully evaluated by any regulatory authority.
