CHMP recommends approval of Dupixent (dupilumab) for asthma indication

PARIS and TARRYTOWN, NY –  The European Medicines Agency’s
Committee for Medicinal Products for Human Use (CHMP) has adopted a positive
opinion for Dupixent® (dupilumab), recommending its approval in the European Union
for use in adults and adolescents 12 years and older as 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 inhaled
corticosteroid plus another medicinal product for maintenance treatment.
The positive CHMP opinion is based on clinical data from 2,888 adults and adolescents
who participated in three pivotal trials from the global LIBERTY ASTHMA program,
including the Phase 3 QUEST and VENTURE trials. QUEST compared Dupixent vs.
placebo in asthma patients inadequately controlled on a medium or high dose inhaled
corticosteroid and a second controller medication. VENTURE compared Dupixent vs.
placebo in oral corticosteroid dependent asthma patients. The European Commission is
expected to make a final decision on the application for Dupixent in the coming months.
Dupixent is a human monoclonal antibody that inhibits the signaling of interleukin-4 (IL4) and interleukin-13 (IL-13), two key proteins that play a central role in type 2
inflammation that underlies specific types of asthma as well as several other allergic
diseases. This effect is associated with the reduction of type 2 inflammatory biomarkers
including fractional exhaled nitric oxide (FeNO), immunoglobulin E (IgE) and eotaxin-3
Patients with severe asthma often have uncontrolled, persistent symptoms despite
standard-of-care therapy that may make them suitable for treatment with a biologic
therapy. Symptoms of uncontrolled disease include coughing, wheezing and difficulty
breathing, and these patients are at risk of severe asthma attacks that may require
emergency room visits or hospitalizations. Oral corticosteroids can provide relief for
severe, short-term symptoms; however, current asthma guidelines suggest limiting their
chronic use to the most severe patients due to the potential for serious side effects.
Dupixent is being developed jointly by Sanofi and Regeneron as part of a global
collaboration agreement. In October 2018, Dupixent was approved in the U.S. as an
add-on maintenance therapy in patients with moderate-to-severe asthma aged 12 years
and older with an eosinophilic phenotype or with oral corticosteroid-dependent asthma.
Dupixent is not used to treat sudden breathing problems. Dupixent is currently under
regulatory review for specific types of asthma in Japan.
Dupixent is currently approved in the European Union for use in adults with moderate-tosevere atopic dermatitis who are candidates for systemic therapy. Dupixent is also
approved for use in specific patients with moderate-to-severe atopic dermatitis in a
number of other countries around the world.
Dupilumab development program
Sanofi and Regeneron are also studying dupilumab in a broad range of clinical
development programs for diseases driven by type 2 inflammation, including chronic
rhinosinusitis with nasal polyps (Phase 3 completed), pediatric (6 to 11 years of age)
atopic dermatitis (Phase 3), pediatric (6 months to 5 years of age) atopic dermatitis
(Phase 2/3), adolescent (12 to 17 years of age) atopic dermatitis (Phase 3 completed),
pediatric (6 to 11 years of age) asthma (Phase 3), eosinophilic esophagitis (Phase 2/3)
and food and environmental allergies (Phase 2). A future trial is planned for chronic
obstructive pulmonary disease. Dupilumab is also being studied in combination with
REGN3500, which targets IL-33. These potential uses are investigational and the safety
and efficacy have not been evaluated by any regulatory authority.
