Regeneron Pharmaceuticals, Inc. and Sanofi announced that the European Medicines Agency's Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion, recommending to extend the approval of Dupixent (dupilumab) in the European Union (EU) to include add-on maintenance treatment for children aged 6 to 11 years with severe asthma with type 2 inflammation characterized by raised blood eosinophils and/or raised fractional exhaled nitric oxide (FeNO) who are inadequately controlled on two maintenance therapies. The European Commission is expected to announce a final decision on the Dupixent application in the coming months.

The CHMP positive opinion is supported by phase 3 data recently published in the New England Journal of Medicine showing that Dupixent added to standard of care significantly reduced the rate of severe asthma attacks and rapidly improved lung function within two weeks, with sustained improvement up to 52 weeks, in children with uncontrolled moderate-to-severe asthma. The safety results from the trial were generally consistent with the known safety profile of Dupixent in patients aged 12 years and older with uncontrolled moderate-to-severe asthma. Adverse events more commonly observed with Dupixent compared to placebo included injection site reactions, viral upper respiratory tract infections and eosinophilia. Helminth infections were also more commonly observed with Dupixent compared to placebo in patients aged 6 to 11 years.

Asthma is one of the most common chronic diseases in children. Up to 85% of children with asthma may have type 2 inflammation and are more likely to have higher disease burden. Despite treatment with current standard-of-care inhaled corticosteroids (ICS) and bronchodilators, these children may continue to experience serious symptoms such as coughing, wheezing and difficulty breathing. Severe asthma may impact children's developing airways and cause potentially life-threatening exacerbations. Children with severe asthma also may require the use of multiple courses of systemic corticosteroids that carry significant risks. Uncontrolled severe asthma can interfere with day-to-day activities like sleeping, attending school and playing sports.

On October 20, 2021, Dupixent was approved by the FDA as an add-on maintenance treatment for patients aged 6 to 11 years with moderate-to-severe asthma characterized by an eosinophilic phenotype or with oral corticosteroid-dependent asthma. The use of Dupixent in children aged 6 to 11 years with uncontrolled severe asthma is investigational in the EU and is not yet approved.

Dupixent, which was invented using Regeneron's proprietary VelocImmune technology, is a fully human monoclonal antibody that inhibits the signalling of the interleukin-4 (IL-4) and interleukin-13 (IL-13) pathways and is not an immunosuppressant. IL-4 and IL-13 are key and central drivers of the type 2 inflammation that plays a major role in atopic dermatitis, asthma and chronic rhinosinusitis with nasal polyposis (CRSwNP).

Dupixent is currently approved in Europe for adults and adolescents 12 years and older as an add-on maintenance treatment for severe asthma with type 2 inflammation characterized by raised blood eosinophils and/or raised FeNO, who are inadequately controlled with high-dose ICS plus another medicinal product for maintenance treatment. It is also approved in the U.S., Japan and other countries around the world for use in certain patients with asthma, specific patients with moderate-to-severe atopic dermatitis as well as CRSwNP in different age populations. Dupixent is also approved in one or more of these indications in more than 60 countries around the world, and more than 350,000 patients have been treated globally.

Regeneron's VelocImmune technology utilizes a proprietary genetically engineered mouse platform endowed with a genetically humanized immune system to produce optimized fully human antibodies. When Regeneron's president and chief scientific officer George D. Yancopoulos was a graduate student with his mentor Frederick W. Alt in 1985, they were the first to envision making such a genetically humanized mouse, and Regeneron has spent decades inventing and developing VelocImmune and related VelociSuite technologies. Dr. Yancopoulos and his team have used VelocImmune technology to create approximately a quarter of all original, FDA-approved or authorized fully human monoclonal antibodies currently available. This includes Dupixent, REGEN-COV (casirivimab and imdevimab), Libtayo (cemiplimab-rwlc), Praluent (alirocumab), Kevzara (sarilumab), Evkeeza (evinacumab-dgnb) and Inmazeb (atoltivimab, maftivimab, and odesivimab-ebgn).

Dupilumab is being jointly developed by Regeneron and Sanofi under a global collaboration agreement. To date, dupilumab has been studied across 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 including chronic obstructive pulmonary disease with evidence of type 2 inflammation (Phase 3), pediatric atopic dermatitis (6 months to 5 years of age, Phase 3), eosinophilic esophagitis (Phase 3), bullous pemphigoid (Phase 3), prurigo nodularis (Phase 3), chronic spontaneous urticaria (Phase 3), chronic inducible urticaria-cold (Phase 3), chronic rhinosinusitis without nasal polyposis (Phase 3), allergic fungal rhinosinusitis (Phase 3), allergic bronchopulmonary aspergillosis (Phase 3) and peanut allergy (Phase 2). 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.
