Sanofi Dupixent Phase 3 trial shows positive results in children with eosinophilic esophagitis as young as age 1

Paris: Sanofi has recently announced the company's Phase 3 trial assessing the investigational use of Dupixent (dupilumab) in children aged 1 to 11 years with eosinophilic esophagitis (EoE) met its primary endpoint of histological disease remission at 16 weeks with both higher and lower dose weight-tiered regimens. There are no approved treatments for children with EoE under 12 years of age.
Naimish Patel, M.D., Senior Vice President, Head of Global Development, Immunology and Inflammation, Sanofi said, "We are incredibly excited to share results from this Phase 3 pivotal trial evaluating Dupixent in young children suffering from eosinophilic esophagitis – the first ever to show positive results across a variety of primary and secondary endpoints. The lack of treatment options for children living with eosinophilic esophagitis leaves many caregivers with the stress and burden of adapting their child's meals and their entire family's daily schedules to ensure healthy growth and development. In some cases, they must resort to off-label use of poorly studied treatments like steroids that can pose serious health risks when used long term. The faster and larger than anticipated enrollment in this trial further emphasizes the unmet treatment needs for children with EoE and underscores the significance of these first-ever positive results."
EoE is a chronic inflammatory disease that damages the esophagus and prevents it from working properly. The results seen with Dupixent in adults and children with EoE demonstrate that IL-4 and IL-13 are key drivers of the type 2 inflammation underlying this disease. In children, common symptoms of eosinophilic esophagitis include acid reflux, vomiting, abdominal discomfort, trouble swallowing, and a failure to thrive. These symptoms can impact growth and development, and can cause food-related fear and anxiety which can persist through adulthood. Diet adjustments, which oftentimes include the elimination of many foods, is the standard treatment for EoE, as well as the use of treatments not approved for the disease. These include proton pump inhibitors, swallowed topical corticosteroids, or in severe cases, a feeding tube, which may be used to ensure proper caloric intake and weight gain. Of the approximately 21,000 children under the age of 12 in the U.S. currently being treated for EoE, about 9,000 do not satisfactorily respond to the unapproved therapies they have been treated with and potentially require advanced therapy.
