Sanofi, Regeneron Dupixent sBLA accepted for USFDA review for chronic spontaneous urticaria
Paris: Sanofi and Regeneron has announced that the US Food and Drug Administration (FDA) has accepted for review the resubmission of the supplemental biologics license application (sBLA) for Dupixent (dupilumab) to treat adults and pediatric patients aged 12 years and older with chronic spontaneous urticaria (CSU) whose disease is not adequately controlled with H1 antihistamine treatment. The target action date for the FDA decision is April 18, 2025.
The resubmitted sBLA is supported by data from the multi-study LIBERTY-CUPID phase 3 clinical program (Study A, Study B, and Study C) for Dupixent in CSU. The sBLA adds results from Study C, which was conducted in patients with uncontrolled CSU who were on standard-of-care antihistamines. Study C, the second LIBERTY-CUPID pivotal study in biologic-naïve patients, met its primary and key secondary endpoints, confirming results seen in the previous Study A. Results showed Dupixent significantly reduced itch and urticaria activity (itch and hives).
Safety results in all LIBERTY-CUPID phase 3 studies were generally consistent with the known safety profile of Dupixent in its approved indications.
CSU is a chronic inflammatory skin disease driven in part by type-2 inflammation, which causes sudden and debilitating hives and recurring itch. CSU is typically treated with H1 antihistamines, medicines that target H1 receptors on cells to control symptoms of urticaria. However, the disease remains uncontrolled despite antihistamine treatment in many patients, some of whom are left with limited alternative treatment options. These individuals continue to experience symptoms that can be debilitating and significantly impact their quality of life. More than 300,000 people in the US suffer from CSU that is inadequately controlled by antihistamines.
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 polyps, eosinophilic esophagitis, prurigo nodularis, CSU, and chronic obstructive pulmonary disease in different age populations. More than 1,000,000 patients are currently being treated with Dupixent globally.
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 in part by type-2 inflammation or other allergic processes in phase 3 studies, including chronic pruritus of unknown origin 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.
