Sanofi Dupixent under USFDA priority review for adults with prurigo nodularis

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 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.

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.
