Dupixent® (dupilumab) Approved for Severe Asthma by European Commission
Only biologic approved in the EU for severe asthma with type 2 inflammation, as characterized by raised blood eosinophils and/or raised fractional exhaled nitric oxide (FeNO)
In clinical trials, Dupixent improved lung function and quality of life, and reduced severe exacerbations and oral corticosteroid use
"People whose severe asthma is inadequately controlled on current therapy continue to have trouble breathing and suffer potentially life-threatening exacerbations. This daily burden and unpredictability can significantly diminish quality of life, causing missed days of school, work and social activities," said
Despite standard-of-care treatment, people with severe asthma often have inadequately controlled, persistent symptoms that may make them suitable for treatment with a biologic therapy. These patients live with coughing, wheezing and difficulty breathing, and are at risk of severe asthma attacks that may require emergency room visits or hospitalizations. In addition to taking maintenance ICS treatment, patients with severe asthma often rely on oral corticosteroids (OCS) when their symptoms worsen. While OCS treatment can provide relief for severe symptoms, current asthma guidelines suggest limiting their chronic use to the most severe patients due to the potential for serious side effects.
"Type 2 inflammation is responsible for many of the hallmark symptoms of asthma – and Dupixent is the first and only treatment approved for patients in the
Dupixent is a human monoclonal antibody that inhibits the signaling of interleukin-4 (IL-4) 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 FeNO, immunoglobulin E (IgE) and eotaxin-3 (CCL26).

About the LIBERTY ASTHMA Clinical Program
The EC approval 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 and a Phase 2b trial. QUEST enrolled 1,902 patients with persistent asthma and evaluated whether adding Dupixent to standard-of-care therapy could reduce severe exacerbations and improve lung function (measured by FEV1). VENTURE enrolled 210 patients with severe oral corticosteroid-dependent asthma and evaluated whether adding Dupixent to standard-of-care therapy could reduce the use of maintenance oral corticosteroids. The Phase 2b trial enrolled 776 adult patients with moderate-to-severe asthma and evaluated whether adding Dupixent to standard-of-care therapy could improve lung function.
In these trials, Dupixent:
- Reduced severe exacerbations: In QUEST, by week 52 exacerbations were reduced by up to 67% compared to placebo in patients with eosinophils ≥300 cells/microliter and up to 65% for those with FeNO levels ≥25 parts per billion. In the Phase 2b trial, by week 24 exacerbations were reduced by up to 81% compared to placebo in patients with eosinophils ≥300 cells/microliter.
- Improved lung function: In QUEST, by week 12 Dupixent improved FEV1 by up to 33% (vs. up to 16% for placebo) in patients with blood eosinophils of ≥300 cells/microliter and up to 30% (vs. up to 14% for placebo) in patients with FeNO ≥25 parts per billion. In the Phase 2b trial, by week 12 Dupixent improved FEV1 by up to 26% (vs. 10% for placebo) in patients with blood eosinophils of ≥300 cells/microliter.
- Reduced oral corticosteroid use: In VENTURE, by week 24 more than half of Dupixent patients completely eliminated oral corticosteroids, and overall use reduced by 70% (vs. 42% for placebo).
- Safety: In asthma clinical trials, the most common adverse reaction was injection site erythema (redness). Anaphylactic reaction has been reported very rarely in the asthma development program.
All trials enrolled patients irrespective of minimum baseline type 2 inflammatory biomarkers, such as eosinophils or FeNO levels. Recently updated Global Initiative for Asthma (GINA) guidelines characterize type 2 inflammation as eosinophils ≥150 cells/microliter or FeNO ≥20 parts per billion. In these pivotal asthma trials, patients with eosinophils ≥150 cells/microliter or FeNO ≥25 parts per billion benefited most from Dupixent. In the Phase 2b trial and QUEST, the greatest improvements in exacerbations and lung function were observed in patients with higher baseline levels of type 2 disease. In VENTURE the effect of Dupixent on oral corticosteroid use, exacerbations and lung function was similar, irrespective of baseline levels of type 2 inflammation.
Dupixent is also approved in the EU for the treatment of adults with moderate-to-severe atopic dermatitis who are candidates for systemic therapy. In
Dupixent comes in a 200 mg pre-filled syringe for patients with severe asthma or a 300 mg pre-filled syringe for those who have severe asthma and are on oral corticosteroids or with co-morbid moderate-to-severe atopic dermatitis. It is given as a subcutaneous injection every other week at different injection sites after the initial loading dose. Dupixent can be given in a clinic or at home by self-administration after training by a healthcare professional.
In addition to the currently approved indications, Regeneron and

DUPIXENT is a prescription medicine used:
- to treat people 12 years of age 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 12 years of age.
- with other asthma medicines for the maintenance treatment of moderate-to-severe 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.
