Dupixent® (dupilumab) recommended for EU approval by the CHMP for the treatment of eosinophilic esophagitis
Paris and Tarrytown, N.Y. DECEMBER 16, 2022 The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion, recommending the approval of Dupixent® (dupilumab) in the European Union (EU) to treat adults and adolescents with eosinophilic esophagitis (EoE). This positive opinion covers those who are 12 years and older, weighing at least 40 kg, and inadequately controlled by, are intolerant to or who are not candidates for conventional medicinal therapy. The European Commission is expected to announce a final decision on the Dupixent application in the coming months. In May 2022, Dupixent 300 mg weekly was approved by the U.S. Food and Drug Administration for the treatment of patients aged 12 years and older, weighing at least 40 kg.
EoE is a chronic, progressive inflammatory disease that damages the esophagus and prevents it from working properly. The results seen with Dupixent in adults and adolescents with EoE demonstrate that interleukin-4 (IL-4) and interleukin-13 (IL-13) are key and central drivers of the type 2 inflammation underlying this disease. For people with EoE, swallowing even small amounts of food can be a painful and worrisome choking experience. They are often left to contend with the frustration and anxiety of a constantly evolving list of foods to avoid, a poor quality of life and a higher risk of depression. In cases where EoE causes the esophagus to narrow, forced and potentially painful dilation (physical expansion) of the esophagus may be needed. In severe cases, a feeding tube may be the only option to ensure proper caloric intake and adequate nutrition.
The positive CHMP opinion is supported by 52-week data from a Phase 3 trial consisting of three parts – Part A and Part B investigated Dupixent 300 mg weekly compared to placebo for 24 weeks, and Part C observed patients from Parts A and B, all of whom were on Dupixent, having continued on or switched to Dupixent for an additional 28 weeks. The results demonstrated Dupixent-treated patients experienced improvements in their ability to swallow as early as four weeks, as well as histological disease remission, improvements in abnormal endoscopic findings of the esophagus and cellular improvements at 24 weeks compared to placebo, with outcomes maintained up to one year. The safety results of the trial were generally consistent with the known safety profile of Dupixent in its approved indications. Adverse events more commonly observed with Dupixent compared to placebo included infections.
The use of Dupixent in adults and adolescents with EoE is investigational in the EU and is not yet approved.
Dupixent is a fully human monoclonal antibody that inhibits the signaling of the IL-4 and 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 trials, 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. These diseases include approved indications for Dupixent, such as atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP) and prurigo nodularis, as well as investigational diseases such as EoE in the EU.
Dupixent has received regulatory approvals in one or more countries around the world for use in certain patients with atopic dermatitis, asthma, CRSwNP, EoE or prurigo nodularis in different age populations. Dupixent is currently approved for one or more of these indications in more than 60 countries, including in Europe, the U.S. and Japan. More than 500,000 patients have been 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 trials 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 trials, including pediatric EoE, hand and foot atopic dermatitis, chronic inducible urticaria-cold, chronic spontaneous urticaria, chronic pruritus of unknown origin, chronic obstructive pulmonary disease with evidence of type 2 inflammation, chronic rhinosinusitis without nasal polyposis, allergic fungal rhinosinusitis, allergic bronchopulmonary aspergillosis 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.
Regeneron is a leading biotechnology company that invents, develops and commercializes life-transforming medicines for people with serious diseases. Founded and led for nearly 35 years by physician-scientists, our unique ability to repeatedly and consistently translate science into medicine has led to nine FDA-approved treatments and numerous product candidates in development, almost all of which were homegrown in our laboratories.
