Dupixent sBLA accepted for FDA review for the treatment of chronic spontaneous urticaria
Resubmission includes new pivotal data which confirm Dupixent significantly reduced itch and hive activityMore than 300,000 people in the US suffer from chronic spontaneous urticaria (CSU) that is inadequately controlled by antihistaminesFDA decision expected by April 18, 2025; if approved, Dupixent would be the first targeted therapy for CSU in a decade Paris and Tarrytown, NY, November 15, 2024. 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. Adverse events more commonly observed with Dupixent (≥5%) compared to placebo were injection site reactions and COVID-19 infection. About CSUCSU 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.
About Dupixent in CSU The LIBERTY-CUPID Phase 3 study program evaluating Dupixent for CSU consists of Study A, Study B, and Study C. Study A and Study C were conducted in CSU patients who were uncontrolled on standard-of-care antihistamines while Study B was conducted in CSU patients who were uncontrolled on standard-of-care antihistamines and refractory or intolerant to omalizumab.
Dupixent has been approved for CSU in Japan and the United Arab Emirates (UAE) and is also under regulatory review in the EU based on earlier study readouts. Outside of Japan and the UAE, the safety and efficacy of Dupixent for CSU has not been fully evaluated by any regulatory authority. About DupixentDupixent (dupilumab) is a fully human monoclonal antibody that inhibits the signaling of the IL4 and IL13 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 IL4 and IL13 are two of the key and central drivers of type-2 inflammation that play 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 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 development programDupilumab 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.
