Dupixent® (dupilumab) Approved by European Commission as First and Only Targeted Medicine for Children as Young as Six Months Old with Severe Atopic Dermatitis
Approximately seven times as many patients aged 6 months to 5 years with severe atopic dermatitis treated with Dupixent experienced clear or almost clear skin and reduced overall disease severity compared to placebo
Patients treated with Dupixent achieved rapid itch reduction as early as three weeks after start of therapy, with significant improvements at 16 weeks sustained through one year
Dupixent is now a treatment option for the approximately 80,000 infants and young children living with uncontrolled severe atopic dermatitis in
Milestone marks third
“Watching an infant or young child grapple with the debilitating and wide-reaching impacts of severe atopic dermatitis is heartbreaking,” said
Atopic dermatitis is a chronic type 2 inflammatory skin disease. Between 85% and 90% 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, crusting and oozing, which can increase the risk of skin infection. Severe atopic dermatitis may also significantly impact the quality of life of young children and their caregivers. Treatment options in this age group are primarily topical corticosteroids (TCS), which can be associated with safety risks and may impair growth when used long-term.
“No infant or child should have to spend their earliest days suffering with the intense and unrelenting itch and skin pain of atopic dermatitis,” said George
“A vast majority of people with atopic dermatitis begin to develop symptoms during their earliest, most vulnerable years, and these symptoms can often continue through the rest of their lives. With this latest approval, Dupixent is the first-ever biologic medicine for people living with atopic dermatitis from infancy to adulthood,” said Naimish Patel, M.D., Head of Global Development, Immunology and Inflammation at Sanofi. “Given its well-established safety and efficacy profile, Dupixent has the potential to transform the landscape for people of all ages living with atopic dermatitis. We remain committed to exploring Dupixent for the treatment of other chronic inflammatory skin diseases.”
The approval is based on data from a Phase 3 trial evaluating Dupixent every four weeks (200 mg or 300 mg based on body weight) plus low-potency TCS or TCS alone (placebo) in 162 children aged 6 months to 5 years with moderate-to-severe atopic dermatitis. At 16 weeks, Dupixent improved skin clearance and reduced overall disease severity and itch compared to placebo in the overall enrolled population. In a subset of those with severe atopic dermatitis, patients randomized to Dupixent (n=63) experienced the following compared to placebo (n=62) at 16 weeks:
- 46% of patients achieved 75% or greater improvement in overall disease severity compared to 7% treated with placebo, a co-primary endpoint.
- 14% of patients achieved clear or almost clear skin compared to 2% treated with placebo, a co-primary endpoint.
- 55% average reduction in overall disease severity from baseline compared to 10% with placebo.
- 42% average reduction in itch from baseline compared to a 1% increase with placebo.
Dupixent also improved sleep quality, skin pain and health-related quality of life compared to placebo in both the overall and severe populations. Long-term efficacy data showed the clinical benefit at 16 weeks was sustained through 52 weeks.
The most common side effects across indications include injection site reactions, conjunctivitis, conjunctivitis allergic, arthralgia, oral herpes and eosinophilia. The safety results of the 6 months to 5 years old trial were generally consistent with the known safety profile of Dupixent in its approved indications; in the trial, adverse events more commonly observed (≥5%) with Dupixent compared to placebo included eosinophilia and conjunctivitis. The long-term safety profile through 52 weeks was similar to the safety profile observed at 16 weeks, and consistent with what was observed in older patients with atopic dermatitis.
About the Pivotal Dupixent Atopic Dermatitis 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 moderate-to-severe atopic dermatitis.
The co-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 (
Dupixent is an injection administered 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.
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), eosinophilic esophagitis (EoE) and prurigo nodularis.
Dupixent has received regulatory approvals in one or more countries around the world for use in certain patients with atopic dermatitis, asthma, CRSwNP, EoE or prurigo nodularis in different age populations. Dupixent is currently approved for one or more of these indications in more than 60 countries, including in

Dupilumab Development Program
Dupilumab is being jointly developed by Regeneron and Sanofi 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, Regeneron and Sanofi are studying dupilumab in a broad range of diseases driven by type 2 inflammation or other allergic processes in Phase 3 trials, including pediatric EoE, chronic inducible urticaria-cold, chronic spontaneous urticaria, chronic pruritus 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.
DUPIXENT is a prescription medicine used:
- to treat adults and children 6 months of age and older with moderate-to-severe eczema (atopic dermatitis or AD) that is not well controlled with prescription therapies used on the skin (topical), or who cannot use topical therapies. DUPIXENT can be used with or without topical corticosteroids. It is not known if DUPIXENT is safe and effective in children with atopic dermatitis under 6 months of age.
- with other asthma medicines for the maintenance treatment of moderate-to-severe eosinophilic or oral steroid dependent asthma in adults and children 6 years of age and older whose asthma is not controlled with their current asthma medicines. DUPIXENT helps prevent severe asthma attacks (exacerbations) and can improve your breathing. DUPIXENT may also help reduce the amount of oral corticosteroids you need while preventing severe asthma attacks and improving your breathing. DUPIXENT is not used to treat sudden breathing problems. It is not known if DUPIXENT is safe and effective in children with asthma under 6 years of age.
- with other medicines for the maintenance treatment of chronic rhinosinusitis with nasal polyposis (CRSwNP) in adults whose disease is not controlled. It is not known if DUPIXENT is safe and effective in children with chronic rhinosinusitis with nasal polyposis under 18 years of age.
- to treat adults and children 12 years of age and older, who weigh at least 88 pounds (40 kg), with eosinophilic esophagitis (EoE). It is not known if DUPIXENT is safe and effective in children with eosinophilic esophagitis under 12 years of age and who weigh at least 88 pounds (40 kg).
- to treat adults with prurigo nodularis (PN). It is not known if DUPIXENT is safe and effective in children with prurigo nodularis under 18 years of age.
