Late-Breaking Dupixent® (dupilumab) Data at ERS 2022 Show Consistent Efficacy and Safety Profile for Up to Two Years in Children Aged 6 to 11 Years with Moderate-to-severe Asthma
Results from the longest global Phase 3 open-label extension trial in this age group in asthma show sustained improvement in lung function, low rate of asthma attacks and a consistent safety profile for up to two years
"Children with uncontrolled moderate-to-severe asthma may experience long-term persistent coughing, difficulty breathing, unpredictable asthma attacks and impaired lung function, which can lead to complications later in life as they grow and develop," said
The results are from data in children who entered the extension trial after finishing active treatment or placebo in the Phase 3 trial (pivotal trial). Children in the extension trial were treated for up to an additional year with Dupixent, providing up to two years of data in total. Children treated with Dupixent in the extension trial experienced a:
- Low rate of severe asthma attacks with an average of 0.118-0.124 events per year, compared to 2.16-2.56 events per year at baseline in the pivotal trial.
- Sustained improvement in lung function at 52 weeks of 9.43-12.6 percentage points from baseline in the pivotal trial, measured by percent predicted FEV1 (FEV1pp). FEV1pp seeks to evaluate a patient's change in lung function compared to their predicted lung function based on age, height, sex and ethnicity to account for children's growing lung capacity at different stages of development.
- Children who switched from placebo in the pivotal trial to Dupixent in the extension trial demonstrated improvement of 8.71 percentage points in lung function at two weeks.
The safety results of the trial were generally consistent with the known safety profile of Dupixent in its approved respiratory indications. Over the 52-week treatment period, the overall rates of adverse events (AEs) were 61-68%. The most common AEs (≥5%) were nasopharyngitis (9-10%), pharyngitis (6-10%), upper respiratory tract infection (4-8%), influenza (5-6%), eosinophilia (3-6%), allergic rhinitis (3-7%), diarrhea (4-6%) and injection site reactions (3-7%).
About Pediatric Asthma
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 and bronchodilators, these children may continue to experience serious symptoms such as coughing, wheezing and difficulty breathing. They also may require the use of multiple courses of systemic corticosteroids that carry significant risks.
About the LIBERTY ASTHMA EXCURSION Trial
The Phase 3, multicenter, open-label extension trial evaluated the long-term safety and efficacy of Dupixent in 365 children with uncontrolled moderate-to-severe asthma who had previously participated in the placebo-controlled VOYAGE trial (the pivotal trial) when they were 6 to 11 years of age. Based on body weight, patients in the open-label extension trial received Dupixent 100 mg or 200 mg every two weeks or Dupixent 300 mg every four weeks, for 52 weeks.
The primary endpoint assessed the number of patients experiencing any treatment emergent adverse event. Secondary endpoints included the annualized rate of severe asthma exacerbations over one year and change from pivotal trial baseline in FEV1pp.
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 asthma, atopic dermatitis, chronic rhinosinusitis with nasal polyposis (CRSwNP) and eosinophilic esophagitis (EoE), as well as investigational diseases such as prurigo nodularis.
In the EU, Dupixent is approved in children aged 6 to 11 years 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 medium to high dose inhaled corticosteroids (ICS) plus another medicinal product for maintenance treatment. For adolescents and adults 12 years and older with severe asthma with type 2 inflammation, patients must be inadequately controlled with high dose ICS plus another medicinal product for maintenance treatment.
Dupixent has received regulatory approvals around the world for use in in certain patients with atopic dermatitis, asthma, CRSwNP or EoE in different age populations. Dupixent is currently approved across these indications in the

DUPIXENT is a prescription medicine used:
- to treat adults and children 6 months 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 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).
