A Sanofi and Regeneron study published on 11 December 2023 found that dupilumab (compared to placebo) significantly improved lung function in children with uncontrolled asthma. The study was randomised with subjects aged between 6-12 years, and the results showed that by week 12, a higher proportion of patients achieved a clinically meaningful response.
On 25 January 2024, Regeneron and Sanofi announced that the FDA approved Dupixent® (dupilumab) to treat paediatric patients, aged 1 to 11 years and weighing at least 15 kg, with eosinophilic esophagitis (EoE).
