'Moderate-to-severe atopic dermatitis in babies and young children is more than just a rash - the intense itch can make them scratch uncontrollably throughout the day and night and cause their skin to crack and bleed,' said
Atopic dermatitis is a chronic type 2 inflammatory skin disease. Eighty-five to ninety percent of patients first develop symptoms before 5 years of age, which can often continue through adulthood. Symptoms include intense, persistent itch and skin lesions that cover much of the body, resulting in skin dryness, cracking, pain, redness or darkening, and crusting and oozing. In the
'Young children with moderate-to-severe atopic dermatitis are a significantly underserved population of patients, who spend vulnerable years of their lives suffering through the relentless and far-reaching effects of this chronic disease,' said
'Until today, treatment options in the
The FDA evaluated Dupixent under Priority Review, which is reserved for medicines that represent potentially significant improvements in efficacy or safety in treating serious conditions. The approval is based on data that include a Phase 3 trial evaluating Dupixent every four weeks (200 mg or 300 mg, based on body weight) plus low-potency topical corticosteroids (TCS) or TCS alone. The trial met the primary and all secondary endpoints. At 16 weeks, patients who received Dupixent with TCS experienced the following, compared to TCS alone (placebo):
28% achieved clear or almost-clear skin compared to 4% with placebo, the primary endpoint.
53% achieved 75% or greater improvement in overall disease severity from baseline compared to 11% with placebo, the co-primary endpoint outside of the
48% achieved clinically meaningful reduction in itch compared to 9% with placebo.
The safety profile of Dupixent observed through 16 weeks in children aged 6 months to 5 years was similar to the safety profile in patients 6 years and older with atopic dermatitis. The long-term safety profile of Dupixent in children aged 6 months to 5 years through 52 weeks was also similar to the safety profile observed in the pivotal trial and consistent with what was observed in older patients with atopic dermatitis. Hand-foot-and-mouth disease and skin papilloma were, respectively, reported in 5% and 2% of Dupixent patients aged 6 months to 5 years, and none of these cases led to treatment discontinuation.
About the Dupixent Trial
The Phase 3 randomized, double-blind, placebo-controlled trial evaluated the efficacy and safety of Dupixent added to standard-of-care low-potency TCS compared to low-potency TCS alone (placebo) in 162 children aged 6 months to 5 years with uncontrolled moderate-to-severe atopic dermatitis.
The primary endpoints assessed the proportion of patients achieving an Investigator's Global Assessment (IGA) score of 0 (clear) or 1 (almost clear) and 75% improvement in Eczema Area and Severity Index (
Children who completed the trials were eligible to enroll in an open-label extension trial to assess the safety and efficacy of long-term treatment with Dupixent in this age group.
About Dupixent
Dupixent is administered as an injection under the skin (subcutaneous injection) at different injection sites. In patients aged 6 months to 5 years, Dupixent is administered with a pre-filled syringe every four weeks based on weight (200 mg for children ?5 to
