FDA accepts Dupixent® (dupilumab) for priority review in adults with prurigo nodularis
- Dupixent would be the first and only medicine specifically indicated to treat prurigo nodularis in the U.S., if approved
- Acceptance marks another important step in advancing Dupixent for a broad range of diseases with underlying type 2 inflammation
Paris and Tarrytown, N.Y. May 31, 2022. The U.S. Food and Drug Administration (FDA) has accepted for priority review the supplemental Biologics License Application (sBLA) for Dupixent® (dupilumab) to treat adults with prurigo nodularis, a chronic inflammatory skin disease that causes extreme itch and skin lesions. The target action date for the FDA decision is September 30, 2022.
The sBLA is supported by data from two pivotal Phase 3 trials evaluating the efficacy and safety of Dupixent in patients 18 years and older with uncontrolled prurigo nodularis (PRIME2 and PRIME). Both trials met the primary and key secondary endpoints, showing Dupixent significantly improved disease signs and symptoms compared to placebo, including reduction in itch and skin lesions. The safety results from these trials were generally consistent with the known safety profile of Dupixent in atopic dermatitis. The adverse event more commonly observed with Dupixent was conjunctivitis.
The FDA grants priority review to therapies that have the potential to provide significant improvements in the treatment, diagnosis or prevention of serious conditions. Additional regulatory filings outside of the US are also planned in 2022. The potential use of Dupixent in prurigo nodularis is currently under clinical development, and the safety and efficacy have not been fully evaluated by any regulatory authority.
About Prurigo Nodularis
People with prurigo nodularis experience intense, persistent itch, with thick skin lesions (called nodules) that can cover most of the body. Prurigo nodularis is often described as painful with burning, stinging and tingling of the skin. The impact of uncontrolled prurigo nodularis on quality of life is one of the highest among inflammatory skin diseases due to the extreme itch and is comparable to other debilitating chronic diseases that can negatively affect mental health, activities of daily living and social interactions. High-potency topical steroids are commonly prescribed but are associated with safety risks if used long term. There are approximately 75,000 people in the U.S. who are unable to control their disease with systemic therapy and are most in need of a treatment option.
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 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 asthma, atopic dermatitis, chronic rhinosinusitis with nasal polyposis and eosinophilic esophagitis, as well as investigational diseases such as prurigo nodularis.
Dupixent is approved for use in certain patients with atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyposis and eosinophilic esophagitis in different age populations in a number of countries around the world. Dupixent is currently approved across these indications in the U.S. and for one or more of these indications in the European Union, Japan and more than 60 countries. More than 400,000 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 in 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 prurigo nodularis, pediatric eosinophilic esophagitis, hand and foot atopic dermatitis, chronic inducible urticaria-cold, chronic spontaneous urticaria, chronic pruritis 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.
