Dupixent recommended for EU approval by the CHMP to treat eosinophilic esophagitis in children as young as 1 year old
- Recommendation based on a phase 3 study showing a significantly greater proportion of children on Dupixent achieved histological remission, compared to placebo, consistent with improvements seen in adults and adolescents
- If approved, Dupixent would be the first and only medicine in the EU indicated for EoE in this age group
Paris and Tarrytown, NY, September 20, 2024. The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion recommending the expanded approval of Dupixent (dupilumab) in the European Union (EU) for eosinophilic esophagitis (EoE) in children down to 1 year of age. The recommendation is for children aged 1 to 11 years who weigh at least 15 kg and who are inadequately controlled by, intolerant to, or who are not candidates for conventional medicinal therapy. The European Commission is expected to announce a final decision in the coming months. Dupixent is already approved in the EU for certain adults and adolescents aged 12 years and older with EoE.
The positive CHMP opinion is supported by a two-part (Part A and B) EoE KIDS phase 3 study in children aged one to 11 years. In Part A, a significantly greater proportion of children receiving weight-based doses of Dupixent achieved histological disease remission at week 16, compared to placebo, with results sustained for up to one year in Part B. At week 16, caregivers of children treated with Dupixent also observed improvements in the frequency and severity of EoE signs, and fewer days with at least one sign of EoE, compared to placebo. These data established a bridge showing the response to Dupixent in children with EoE is similar to that of the approved adult and adolescent EoE populations.
The safety results in the EoE KIDS study were generally consistent with the known safety profile of Dupixent in adolescents and adults with EoE. AEs more commonly observed with Dupixent (≥10%) in either weight-based dosing regimen compared to placebo during Part A were COVID-19, nausea, injection site pain and headache. The long-term safety profile of Dupixent evaluated in Part B was similar to that observed during Part A.
Results from the study were recently published in The New England Journal of Medicine.
The use of Dupixent in children aged one to 11 years with EoE is investigational in the EU and is not yet approved.
About EoE
EoE is a chronic, progressive disease associated with type-2 inflammation that is thought to be responsible for damaging the esophagus and impairing its function. Diagnosis is difficult, as symptoms can be mistaken for other conditions and there are delays in diagnosis. EoE can severely impact a child’s ability to eat and may also cause vomiting, abdominal pain, difficulty swallowing, decreased appetite and challenges thriving. Continuous management of EoE may be needed to reduce the risk of complications and disease progression.
About Dupixent
Dupixent (dupilumab) is a fully human monoclonal antibody that inhibits the signaling of the interleukin-4 (IL4) and interleukin-13 (IL13) pathways and is not an immunosuppressant. The Dupixent development program has shown significant clinical benefit and a decrease in type-2 inflammation in phase 3 studies, establishing that IL4 and IL13 are key and central drivers of the type-2 inflammation that plays a major role in multiple related and often co-morbid diseases.
Dupixent has received regulatory approvals in more than 60 countries in one or more indications including certain patients with atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyps, EoE, prurigo nodularis, chronic spontaneous urticaria, and chronic obstructive pulmonary disease in different age populations. More than 1,000,000 patients are being treated with Dupixent globally.
Dupilumab development program
Dupilumab is being jointly developed by Sanofi and Regeneron under a global collaboration agreement. To date, dupilumab has been studied across more than 60 clinical studies involving more than 10,000 patients with various chronic diseases driven in part by type-2 inflammation.
In addition to the currently approved indications, Sanofi and Regeneron are studying dupilumab in a broad range of diseases driven by type-2 inflammation or other allergic processes in phase 3 studies, including chronic pruritus of unknown origin and bullous pemphigoid. These potential uses of dupilumab are currently under clinical investigation, and the safety and efficacy in these conditions have not been fully evaluated by any regulatory authority.
