Pivotal trial showed more than four times as many children achieved itch reduction and more than three times as many children achieved clear or almost clear skin with Dupixent plus topical corticosteroids (TCS) compared to TCS alone
Nearly three in four children achieved a 75% improvement in disease extent and severity, with an average improvement of approximately 80%
Approximately 80% of children experienced clinically meaningful improvements in a composite of health-related quality of life measures that include sleep, school, emotional well-being and relationships
Expanded approval of Dupixent for these children reinforces well-established, long-term safety profile
TARRYTOWN, NY, USA and PARIS, France I November 30, 2020 I Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Sanofi today announced that the European Commission (EC) has extended the marketing authorization for Dupixent® (dupilumab) in the European Union (EU) to include children 6 to 11 years of age with severe atopic dermatitis who are candidates for systemic therapy. Dupixent is the only systemic medicine approved in the EU to treat these patients.
“As the parent of a child with atopic dermatitis, and someone who works with families impacted by this condition daily, I’ve seen first-hand the enormous physical and mental health burden of this disease, and the toll it can take on the entire family,” said Korey Capozza, MPH, Founder and Executive Director of Global Parents for Eczema Research (GPER). “Young children with severe atopic dermatitis currently have few treatment choices and significant unmet needs. We welcome the addition of new medicines for these underserved patients.”
Atopic dermatitis is a chronic inflammatory disease of the skin that can be debilitating, and severe disease can significantly impact many aspects of life for both children and their families. The current standard of care for children with severe atopic dermatitis in Europe is limited to topical treatments, leaving those with poorly-controlled disease to cope with intense, unrelenting itch and skin lesions that can cover much of the body, resulting in skin cracking, redness or darkening, crusting and oozing. In addition, uncontrolled severe atopic dermatitis can have a substantial emotional and psychosocial impact, causing sleep disturbance, symptoms of anxiety and depression and feelings of isolation in children.
“This approval for Dupixent in the EU represents a major advancement for children with severe atopic dermatitis and their families, who spend countless days and nights tending to their child’s disease with few treatment options to help alleviate the debilitating symptoms,” said George D. Yancopoulos, M.D., Ph.D., President and Chief Scientific Officer at Regeneron. “Dupixent is a novel therapy that addresses a root cause of atopic dermatitis by specifically targeting the underlying type 2 inflammation of the disease. Dupixent has already been used by hundreds of thousands of patients around the world, including those with atopic dermatitis as well as other type 2 inflammatory diseases such as asthma and adults with chronic rhinosinusitis with nasal polyps. We are pleased to bring this paradigm-changing medicine to even younger patients in the EU who need new options beyond steroids or immunosuppressants.”
Dupixent is a fully-human monoclonal antibody that inhibits the signaling of the interleukin-4 (IL-4) and interleukin-13 (IL-13) proteins, that was invented using Regeneron’s proprietary VelocImmune® technology, and is not an immunosuppressant. Data from Dupixent clinical trials have shown that IL-4 and IL-13 are key drivers of the type 2 inflammation that plays a major role in atopic dermatitis, asthma and chronic rhinosinusitis with nasal polyposis (CRSwNP).
“The approval of Dupixent for children in Europe marks another significant milestone for atopic dermatitis patients and their families, broadening the availability of a first-in-class medicine that offers a proven safe and effective treatment for this debilitating skin disease,” said John Reed, M.D., Ph.D., Global Head of Research and Development at Sanofi. “Dupixent’s ability to provide significantly clearer skin, and clinically meaningful reduction of persistent itch, addresses important unmet needs for these children. In addition to atopic dermatitis, we continue to investigate the potential of Dupixent in younger age groups and across a variety of type 2 inflammatory diseases.”
In children aged 6 to 11 years weighing 15 to <60 kg, Dupixent 300 mg is administered as an injection under the skin (subcutaneous injection) every four weeks following the initial loading dose given as two injections 14 days apart. For those weighing ≥60 kg, Dupixent 300 mg is administered every two weeks following the initial loading dose given the same day. The dose may be increased to 200 mg every two weeks in patients weighing 15 to <60 kg based on physician’s assessment.
The EC decision is based primarily on data that includes pivotal Phase 3 efficacy and safety results of Dupixent combined with topical corticosteroids (TCS) compared to TCS alone (placebo) in children 6 to 11 years with severe atopic dermatitis. At 16 weeks, patients in treatment groups of Dupixent 300 mg every four weeks (N=122) or 200 mg every two weeks (N=59) with TCS experienced:
— Improved disease extent and severity:
- 82% average improvement from baseline with Dupixent every four weeks compared to 49% for placebo.
- 80% average improvement from baseline with Dupixent every two weeks compared to 48% for placebo.
- 70% of patients in the every four week treatment group achieved at least a 75% improvement compared to 17% for placebo.
- 75% of patients in the every two week treatment group achieved at least a 75% improvement compared to 26% for placebo.
— Skin clearance:
- 33% of patients achieved clear or almost clear skin with Dupixent every four weeks compared to 11% for placebo.
- 39% of patients achieved clear or almost clear skin with Dupixent every two weeks compared to 10% for placebo.
— Reduced itch:
- 51% of patients achieved clinically significant reduction of itch with Dupixent every four weeks compared to 12% for placebo.
- 61% of patients achieved clinically significant reduction of itch with Dupixent every two weeks compared to 13% for placebo.
- A significantly greater proportion of Dupixent patients achieved improvement in itch as early as four weeks.
— Improved health-related quality of life (HR-QoL):
- 77% of patients experienced clinically meaningful improvement in patient-reported HR-QoL with Dupixent every four weeks compared to 39% for placebo.
- 81% of patients experienced clinically meaningful improvement in patient-reported HR-QoL with Dupixent every two weeks compared to 36% for placebo.
- Dupixent patients also experienced improvements in additional HR-QoL measures assessing disease severity and patient-reported measures such as itch and sleep.
The safety profile of Dupixent in children 6 to 11 years of age followed through week 52, based on an open-label extension trial, was similar to the safety profile observed at week 16 and consistent with the safety profile seen in adults and adolescents with atopic dermatitis. Overall rates of adverse events (AEs) were 65% and 61% for Dupixent every four and two weeks, respectively, and 73% and 75% for placebo. AEs that were more commonly observed with Dupixent included upper respiratory tract infections (11% and 9% for Dupixent every four and two weeks, 10% and 12% for placebo), injection site reactions (10% and 14% for Dupixent every four and two weeks, 6% and 5% for placebo), nasopharyngitis (13% and 3% for Dupixent every four and two weeks, 7% and 10% for placebo), conjunctivitis (7% and 9% for Dupixent every four and two weeks, 4% and 5% for placebo), and fever (3% for both Dupixent groups, 2% and 0% for placebo). Additional prespecified AEs included skin infections (6% and 9% for Dupixent every four and two weeks, 13% for both placebo groups), and herpes viral infections (2% for both Dupixent groups, 5% for both placebo groups).
About the Pediatric Trial
The co-primary endpoints in the pediatric trial were skin clearance, as measured by a score of 0 or 1 on the Investigator’s Global Assessment (IGA), and disease extent and severity, as measured by Eczema Area and Severity Index score (EASI-75).
Secondary endpoints included the average change in EASI score from baseline, and itch as measured by at least a 4-point reduction in itch intensity on a 0 to 10-point scale (weekly average of daily Peak Pruritus Numerical Rating Scale). Additionally, HR-QoL was measured by the proportion of patients who achieved at least six points on the patient-reported Children’s Dermatology Life Quality Index (CDLQI), as well as additional measures from Patient Oriented Eczema Measure (POEM) and SCORing Atopic Dermatitis (SCORAD).
About Dupixent
Dupixent is approved for specific patients with atopic dermatitis, asthma and/or in adults with CRSwNP in a number of countries around the world, including the European Union, U.S. and Japan. Dupixent is currently approved in more than 60 countries, and more than 200,000 patients have been treated globally.
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. No initial lab testing or ongoing lab monitoring is required with Dupixent treatment in any approved indication or age group.
Dupilumab was invented using Regeneron’s VelocImmune® technology that utilizes a proprietary genetically-engineered mouse platform endowed with a genetically-humanized immune system to produce optimized fully-human antibodies. VelocImmune technology has been used to create multiple antibodies including Libtayo® (cemiplimab-rwlc), Praluent® (alirocumab) and Kevzara® (sarilumab), which are approved in multiple countries around the world. Regeneron previously used these technologies to rapidly develop a treatment for Zaire ebolavirus infection, which is approved by the FDA, and to create a potentially preventative and therapeutic investigational medicine for COVID-19 that was recently granted Emergency Use Authorization (EUA).
Dupilumab Development Program
To date, dupilumab has been studied in more than 10,000 patients across 50 clinical trials in various chronic diseases driven by type 2 inflammation.
In addition to the currently approved indications, Regeneron and Sanofi are also studying dupilumab in a broad range of diseases driven by type 2 inflammation and other allergic pathways, including pediatric atopic dermatitis (6 months to 5 years of age, Phase 3), pediatric asthma (6 to 11 years of age, Phase 3), eosinophilic esophagitis (Phase 3), chronic obstructive pulmonary disease (Phase 3), bullous pemphigoid (Phase 3), prurigo nodularis (Phase 3), chronic spontaneous urticaria (Phase 3), and food and environmental allergies (Phase 2). These potential uses are investigational, and the safety and efficacy of dupilumab in these conditions have not been evaluated by any regulatory authority. Dupilumab is being jointly developed by Regeneron and Sanofi under a global collaboration agreement.
U.S. Indications
DUPIXENT is a prescription medicine used:
- to treat people aged 6 years and older with moderate-to-severe atopic dermatitis (eczema) 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 years of age.
- with other asthma medicines for the maintenance treatment of moderate-to-severe eosinophilic or oral steroid dependent asthma in people aged 12 years 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 12 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.
