FDA approves Dupixent to treat patients with eosinophilic esophagitis.- Regeneron + Sanofi.
Regeneron Pharmaceuticals, Inc. and Sanofi announced that the FDA has approved Dupixent (dupilumab) 300 mg weekly to treat patients with eosinophilic esophagitis (EoE) aged 12 years and older, weighing at least 40 kg.
With this approval, Dupixent becomes the first and only medicine specifically indicated to treat EoE in the United States. A regulatory filing for EoE is under review by the European Medicines Agency, and submissions to regulatory authorities in additional countries are planned by the end of 2022.
. "We have waited a long time for an FDA-approved treatment option for eosinophilic esophagitis – an underdiagnosed and misunderstood disease of the esophagus that can make it extremely challenging and uncomfortable to eat and swallow," said Mary Jo Strobel, Executive Director at the American Partnership for Eosinophilic Disorders (APFED). "Before today, there were no approved treatments specifically for eosinophilic esophagitis, resulting in many people needing to maintain a strict diet and live in constant fear of food getting stuck in their throat. We welcome therapeutic options that can provide much-needed relief for these patients."
EoE is a chronic inflammatory disease driven by type 2 inflammation that damages the esophagus and prevents it from working properly. For people with EoE, swallowing even small amounts of food can be a painful and worrisome choking experience. They are often left to contend with the frustration and anxiety of a constantly evolving list of foods to avoid, a poor quality of life and a higher risk of depression. In cases where EoE causes the esophagus to narrow, forced and potentially painful dilation (physical expansion) of the esophagus may be needed. In severe cases, a feeding tube may be the only option to ensure proper caloric intake and adequate nutrition. About 160,000 patients are living with EoE in the U.S. These individuals are currently treated with therapies not specifically approved for the disease, of whom approximately 48,000 continue to experience symptoms despite multiple treatments.
