Dupixent Approved as Asthma Add-on Maintenance
FDA has approved Regeneron Pharmaceuticals and Sanofi’s Dupixent (dupilumab) as an add-on maintenance treatment for patients aged six to 11 years with moderate-to-severe asthma characterized by an eosinophilic phenotype or with oral corticosteroid-dependent asthma.
Approval is based on data from a Phase 3 randomized, double-blind, placebo-controlled trial that evaluated the efficacy and safety of Dupixent combined with standard-of-care asthma therapy in affected children. Those who added Dupixent to standard-of-care experienced a substantially reduced rate of severe asthma attacks, with a 65% average reduction over one year compared to placebo, according to the sponsors. They also saw improved lung function observed as early as two weeks and sustained for up to 52 weeks, and improved asthma control at 24 weeks, with 81% of patients reporting a clinically meaningful improvement based on disease symptoms and impact compared to 64% of placebo patients.
Dupixent is also currently approved for use in patients aged six years and older with uncontrolled moderate-to-severe atopic dermatitis, and for use with other medicines for the maintenance treatment of chronic rhinosinusitis with nasal polyposis in adults whose disease is not controlled.
