U.S. for which type 2 inflammation is an underlying driver
EoE is a chronic, progressive disease driven in part by type 2 inflammation that damages the esophagus and impairs its function. EoE can severely impact a child’s ability to eat, and they may experience heartburn, vomiting, abdominal discomfort, trouble swallowing, food refusal and failure to thrive. These symptoms can adversely impact their growth and development. Continuous treatment of EoE may be needed to reduce the risk of complications and disease progression. Approximately 21,000 children under the age of 12 in the

The FDA approval is based on data from the Phase 3 EoE KIDS trial with two parts (Part A and Part B) evaluating the efficacy and safety of Dupixent in children aged 1 to 11 years with EoE. At 16 weeks, 66% of children who received higher dose Dupixent at tiered dosing regimens based on weight (n=32) achieved histological disease remission (≤6 eosinophils/high power field), the primary endpoint, compared to 3% for placebo (n=29). Histological remission was sustained at week 52, with 17 of 32 (53%) children treated with Dupixent in Parts A and B. Histological remission was also achieved at week 52 in 8 of 15 (53%) children who switched to Dupixent from placebo in Part B. In addition, a greater decrease in the proportion of days with one or more signs of EoE based on Pediatric EoE Sign/Symptom Questionnaire-caregiver version (PESQ-C) was observed in children treated with Dupixent at 16 weeks compared to placebo.
Board co-chair, President and Chief Scientific Officer at Regeneron
“Young children are some of the most vulnerable patients with eosinophilic esophagitis, or EoE, as this debilitating and progressive disease threatens their basic ability to eat. Until today, these children had no approved treatment options specifically for EoE, leaving many with unapproved medicines that failed to target the root cause of their disease. With this approval, Dupixent becomes the first and only treatment option for EoE patients aged 1 year and older, weighing at least 15 kg. By targeting the underlying type 2 inflammation that contributes to this disease, Dupixent has the potential to transform the standard of care for these children as it has for adults and adolescents with EoE.”
The safety profile of Dupixent observed through 16 weeks in children aged 1 to 11 years weighing at least 15 kg was generally similar to the safety profile of Dupixent observed through 24 weeks in adult and pediatric patients aged 12 years and older with EoE. The most common adverse events (≥2%) more frequently observed with Dupixent than placebo were injection site reactions, upper respiratory tract infections, arthralgia (joint pain) and herpes viral infections. In EoE KIDS Part B, one case of helminth infection was reported in the Dupixent arm.
About the Dupixent Pediatric Eosinophilic Esophagitis Trial
The Phase 3 randomized, double-blind, placebo-controlled trial evaluated the efficacy and safety of Dupixent in children aged 1 to 11 years, weighing at least 15 kg, with EoE, as determined by histological, endoscopic and patient- or caregiver-reported measures. At baseline, 97% of these patients had at least one co-existing type 2 inflammatory disease, such as food allergy, allergic rhinitis, asthma and atopic dermatitis.
Part A, a 16-week, double-blind, placebo-controlled treatment period, enrolled 61 patients and evaluated the safety and efficacy of Dupixent in a tiered, weight-based dosing schema. The primary endpoint was histological disease remission, which was defined as peak esophageal intraepithelial eosinophil count of ≤6 eosinophils (eos)/high power field (hpf). Changes in caregiver-reported symptoms (proportion of days with 1 or more EoE signs [e.g., stomach pain, vomiting, food refusal]) were evaluated using PESQ-C.
Part B was a 36-week extended active treatment period (n=47) in which eligible children from Part A in the Dupixent group continued to receive their dose level and those in the placebo group in Part A switched to Dupixent.
About Dupixent
Dupixent, which was invented using Regeneron's proprietary VelocImmune® technology, is a fully human monoclonal antibody that inhibits the signaling of the interleukin-4 (IL-4) and interleukin-13 (IL-13) 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 trials, establishing that IL-4 and IL-13 are key and central drivers of the type 2 inflammation that plays a major role in multiple related and often co-morbid diseases. These diseases include approved indications for Dupixent, such as atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), prurigo nodularis and EoE.
Dupixent has received regulatory approvals in one or more countries around the world for use in certain patients with atopic dermatitis, asthma, CRSwNP, EoE, and prurigo nodularis in different age populations. Dupixent is currently approved for one or more of these indications in more than 60 countries, including in
