Regeneron and Sanofi announced that the FDA has approved Dupixent® (dupilumab) to treat paediatric patients aged 1 to 11 years (weighing at least 15 kg) with eosinophilic esophagitis (EoE). Dupixent® is the first and only medicine approved in the US to treat these patients. It was approved to treat EoE patients 12 years and older in May 2022.
On 6 May 2023, a Regeneron-sponsored study concluded that Regeneron/Sanofi’s Dupixent® (dupilumab) improves histologic, symptomatic, and endoscopic aspects of EoE.
