Dupixent® Gains Positive Recommendation for Young EoE Patients

Dupixent® Receives Positive Opinion for Eosinophilic Esophagitis Treatment

In a significant advancement for pediatric care, the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has issued a positive opinion recommending Dupixent® (dupilumab) for treating eosinophilic esophagitis (EoE) in children as young as one year old.

Key Findings of the Clinical Trials

This recommendation is based on promising results from a Phase 3 trial that demonstrated a notable increase in the proportion of young patients achieving histological remission compared to those receiving a placebo. This aligns with similar benefits seen in adult and adolescent populations, reinforcing the effectiveness of Dupixent across age groups.

If sanctioned by the European Commission, Dupixent would be the first and only medication approved for EoE in the pediatric segment within the EU. This achievement represents a breakthrough, facilitating better treatment options for a condition that significantly impacts children’s health.

Details of the EoE KIDS Phase 3 Trial

The positive opinion from the CHMP comes from a comprehensive examination of the EoE KIDS trial, which involved two pivotal parts. In Part A, children aged between one and eleven received weight-adjusted doses of Dupixent, leading to favorable outcomes; notably, these patients showed significant disease remission by week 16.

Moreover, Part B showcased continued remission effects for up to one year with consistent improvements noted by caregivers in EoE symptom severity. These outcomes provide compelling evidence that Dupixent can deliver comparable benefits to younger patients as it does in older demographics.

Safety Profile and Observations

The safety profile of Dupixent in these trials was consistent with previous findings in adult and adolescent populations. AEs such as COVID-19, nausea, injection site pain, and headaches were monitored, with safety outcomes in the long-term Part B of the trial corroborating initial Phase A results.

Understanding Eosinophilic Esophagitis

EoE is a chronic, progressive inflammatory condition linked to type 2 immune responses, leading to significant esophageal damage and impaired function. The diagnosis remains challenging due to symptom overlap with other disorders, often delaying appropriate interventions.

In children, EoE can lead to a multitude of complications including difficulties in eating, abdominal pain, vomiting, and hindered growth. Thus, effective management is essential to mitigate long-term effects and improve patients' quality of life.

About Dupixent and Its Broad Applications

Dupixent was developed through Regeneron’s advanced VelocImmune technology, designed to target and inhibit interleukin-4 and interleukin-13 pathways, key drivers in type 2 inflammation. Its creation showcased significant clinical improvements in a diverse range of conditions including atopic dermatitis, asthma, and chronic rhinosinusitis.

To date, Dupixent has garnered regulatory approvals in over 60 countries, treating more than one million patients globally. The ongoing clinical development program continues to explore new therapeutic avenues, offering hope to those battling other conditions driven by type 2 inflammation.

Future Clinical Trials for Dupixent

In addition to treating EoE, Dupixent is undergoing investigations for various other conditions, including chronic pruritus and bullous pemphigoid. As these studies progress, they aim to further clarify the safety and efficacy of Dupixent, providing future options for patients suffering from complex inflammatory diseases.
