"Moderate-to-severe atopic dermatitis can place a particularly significant burden on adolescents, who have to deal with oozing skin lesions with unrelenting, intense itching during their formative years," said
Patients treated with DUPIXENT had significant improvement in disease severity at 16 weeks
The primary endpoints were the proportion of patients achieving Investigator's Global Assessment (IGA) score of 0 (clear) or 1 (almost clear) and 75% improvement in Eczema Area and Severity Index (
"Current treatment options for these adolescent patients such as topical steroids, oral steroids, and non-steroidal immunosuppressants can have significant side effects," said
DUPIXENT safety profile was consistent with that seen in adults
For the 16-week treatment period, the overall rate of adverse events was comparable between the DUPIXENT groups and placebo (72% for DUPIXENT every two weeks, 64% for DUPIXENT every four weeks and 69% for placebo). There were no serious adverse events or events leading to treatment discontinuation in either DUPIXENT treatment group. Adverse events that were observed at a higher rate with DUPIXENT included injection site reactions (8.5% for DUPIXENT every two weeks, 6% for DUPIXENT every four weeks compared with 3.5% for placebo) and conjunctivitis (10% for DUPIXENT every two weeks, 11% for DUPIXENT every four weeks compared with 5% for placebo). Skin infections were numerically lower in the DUPIXENT groups (11% for DUPIXENT every two weeks, 13% for DUPIXENT every four weeks compared with 20% for placebo).
Detailed results from this trial will be presented at a future medical meeting. These data will be submitted to regulatory authorities later this year. In 2016, the
The safety and efficacy of DUPIXENT in the adolescent atopic dermatitis population have not been fully evaluated by any regulatory authority.
About the DUPIXENT Trial in Adolescent Patients
The pivotal, Phase 3, randomized, double-blind, placebo-controlled trial evaluated the efficacy and safety of DUPIXENT monotherapy in adolescent patients with moderate-to-severe atopic dermatitis. The trial enrolled 251 patients who were 12 years to 17 years of age with moderate-to-severe atopic dermatitis whose disease could not be adequately controlled with topical medications or for whom topical treatment was medically inadvisable. In total, 92% of these patients suffered from at least one concurrent allergic condition such as allergic rhinitis, asthma or food allergy.
The primary endpoint of this trial was the proportion of patients with an IGA score of 0 or 1 at Week 16. The IGA is a 5-point scale ranging from 0 (clear) to 4 (severe) that measures overall severity of skin lesions. A co-primary endpoint outside of the
Patients were randomized into one of three treatment groups for the controlled period of 16 weeks: the first group was treated with DUPIXENT subcutaneous injection 200 mg or 300 mg every two weeks, based on weight (with an initial dose of 400 mg or 600 mg respectively). The second group was treated with 300 mg DUPIXENT every four weeks (with an initial dose of 600 mg), and the third group was treated with placebo every two weeks.
About Moderate-to-Severe Atopic Dermatitis
Atopic dermatitis, a form of eczema, is a chronic inflammatory disease with symptoms often appearing as a rash on the skin.1,2,3,4 Moderate-to-severe atopic dermatitis is characterized by rashes often covering much of the body, and can include intense, persistent itching and skin dryness, cracking, redness, crusting, and oozing.5 Itch is one of the most burdensome symptoms for patients and can be debilitating.6 In addition, patients with moderate-to-severe atopic dermatitis experience a substantial burden of disease, including painful skin lesions and intense pruritus.6
Dupilumab Development Program
Regeneron and Sanofi are studying dupilumab in a broad range of clinical development programs for diseases driven by Type 2 inflammation, including asthma (Phase 3), pediatric atopic dermatitis (Phase 3, ages 6 months - 11 years), nasal polyps (Phase 3), and eosinophilic esophagitis (Phase 2). Future trials are planned for chronic obstructive pulmonary disease, grass allergy and food allergy (including peanut). These potential uses are investigational and the safety and efficacy have not been evaluated by any regulatory authority. Dupilumab was discovered using Regeneron's proprietary VelocImmune® technology that yields optimized fully-human antibodies, and is being jointly developed by Regeneron and Sanofi under a global collaboration agreement.

DUPIXENT can be used with or without topical corticosteroids. It is not known if DUPIXENT is safe and effective in children. DUPIXENT is administered by subcutaneous injection at different injection sites every two weeks after an initial loading dose. DUPIXENT is intended for use under the guidance of a healthcare provider. A patient may self-inject DUPIXENT after training in subcutaneous injection technique using the pre-filled syringe.
