- Dupixent is the first and only biologic medicine approved to treat moderate-to-severe atopic dermatitis from infancy to adulthood
- Children treated with Dupixent and topical corticosteroids (TCS) achieved clearer skin, and significantly reduced itch compared to TCS alone at week 16 in a Phase 3 trial
- Long-term safety data from a 52-week open-label extension trial in this age group reinforce the well-established safety profile of Dupixent observed across all other approved age groups
PARIS, France and TARRYTOWN, NY, USA I June 7, 2022 I The U.S. Food and Drug Administration (FDA) has approved Dupixent® (dupilumab) for children aged 6 months to 5 years with moderate-to-severe atopic dermatitis whose disease is not adequately controlled with topical prescription therapies or when those therapies are not advisable. A regulatory filing for this age group is under review by the European Medicines Agency and submissions to regulatory authorities in additional countries are underway.

“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. Caregivers do their best to manage skincare routines multiple times a day, but for many, topical treatments are not enough. We’re pleased to see how scientific innovation and research continues to address unmet needs for the atopic dermatitis community, and we’re hopeful for the positive impact Dupixent can have for these children and their families.”
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, along with increased risk of skin infections. In the U.S., more than 75,000 children aged 5 years and younger have uncontrolled moderate-to-severe disease and are most in need of new treatment options.

“Until today, treatment options in the U.S. for infants and children under the age of 6 suffering from moderate-to-severe atopic dermatitis have been limited to topical steroids – which may be associated with significant safety risks when used long-term. This has left patients and their caregivers in desperate need of medicines that can better address the chronic, long-term nature of the disease. These young people, and their families, often struggle to cope with the significant impact itch can have on them. This approval means that Dupixent, with its well-established safety and efficacy profile, is now available to some of the youngest people living with this disease.”
George D. Yancopoulos, M.D., Ph.D.
President and Chief Scientific Officer, Regeneron
“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. Dupixent has changed the atopic dermatitis treatment paradigm – significantly clearing skin and reducing itch – by targeting an underlying cause of this disease without broadly suppressing the immune system. Today’s approval brings the proven efficacy and, importantly, well-established safety profile of Dupixent to these young children, making it the first of its kind to be approved for any U.S. patient aged six months or older living with this debilitating disease.”
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 (placebo). 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:
- 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 TCS alone, the co-primary endpoint outside of the U.S.
- 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 (EASI-75) at week 16. Additional outcome measures included itch reduction which was assessed using a caregiver-reported 0 to 10 Numerical Rating Scale, with a clinically meaningful improvement defined as ≥4-point improvement at week 16.
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 <15 kg and 300 mg for children ≥15 to <30 kg). Dupixent is intended for use under the guidance of a healthcare professional and can be given in a clinic or at home by self-administration after training by a healthcare professional. In children younger than 12 years of age, Dupixent should be administered by a caregiver if given at home. Dupixent does not require initial lab testing or ongoing lab monitoring.
Sanofi and Regeneron are committed to helping patients in the U.S. who are prescribed Dupixent gain access to the medicine and receive the support they may need with the DUPIXENT MyWay® program. For more information, please call 1-844-DUPIXENT (1-844-387-4936) or visit www.DUPIXENT.com.
Dupixent is approved for use in certain patients with atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP) or eosinophilic esophagitis in different age populations in a number of countries around the world. Dupixent is currently approved across these indications in the U.S. and for one or more of these indications in the European Union and Japan and more than 60 countries. More than 400,000 patients have been treated globally.
Dupixent 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 asthma, atopic dermatitis, CRSwNP and eosinophilic esophagitis, as well as investigational diseases such as prurigo nodularis.
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 trials 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 trials, including prurigo nodularis, pediatric eosinophilic esophagitis, hand and foot atopic dermatitis, chronic inducible urticaria-cold, chronic spontaneous urticaria, chronic pruritis of unknown origin, chronic obstructive pulmonary disease with evidence of type 2 inflammation, chronic rhinosinusitis without nasal polyposis, allergic fungal rhinosinusitis, allergic bronchopulmonary aspergillosis 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.
