The treatment for adults and adolescents with the type 2 inflammatory skin condition has been accepted for FDA review.
The US Food and Drug Administration (FDA) accepted review for the supplemental Biologics License Application (sBLA) for dupilumab (Dupixent) in the treatment of chronic spontaneous urticaria (CSU).1 Regeneron Pharmaceuticals, Inc. and Sanofi submitted the review for the drug to treat CSU patients ages 12 and older. The current standard of care for CSU is an H1 antihistamine treatment. More than 300,000 (nearly 50%) CSU patients in the US report their condition is not adequately controlled by antihistamines.
The sBLA is supported by data from 2 phase 3 trials. The LIBERTY-CUPID Studies A (n=138) and B (n=108) were randomized, double-blind, placebo-controlled trials that evaluated the efficacy and safety of dupilumab in CSU treatment. Researchers examined how dupilumab targeted IL-4 and IL-13 proteins in patientswith uncontrolled CSU (ages 12-80) for 24 weeks. Results found the drug significantly reduced both the severity of itch and hives by 65% for patients, which was roughly double the effectiveness of the placebo test groups.
The FDA’s target date for a decision on the sBLA for dupilumab in CSU treatment is October 22, 2023.
CSU is the fifth condition dupilumab could be cleared to treat. Currently, the dupilumab is used as a prescription medicine to:
In addition to CSU, Regeneron and Sanofi are also studying dupilumab’s safety and efficacy in chronic inducible urticaria triggered by cold in an ongoing phase 3 trial.
