Dupixent is now also 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 fractional exhaled nitric oxide (FeNO), who are inadequately controlled with medium to high dose inhaled corticosteroids (ICS) plus another medicinal product for maintenance treatment.
'Today's approval in
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 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.
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. By demonstrating significant clinical benefit together with a decrease in type 2 inflammation following IL-4 and IL-13 blockade with Dupixent, the Dupixent Phase 3 clinical program has established that IL-4 and IL-13 are key drivers of the type 2 inflammation that plays a major role in multiple related and often co-morbid diseases for which Dupixent is approved including asthma, atopic dermatitis and chronic rhinosinusitis with nasal polyposis (CRSwNP), as well as investigational diseases such as eosinophilic esophagitis and prurigo nodularis, which have been studied in Phase 3 trials.
'We are excited to bring the well-established safety and efficacy profile of Dupixent to even younger patients living with uncontrolled severe asthma in
Two pre-specified populations with evidence of type 2 inflammation were evaluated for the primary analysis: 1) patients with baseline blood eosinophils (EOS) 300 cells/l (n=259) and 2) patients with either baseline FeNO 20 parts per billion (ppb) or baseline blood EOS 150 cells/l (n=350). Patients who added Dupixent to standard-of-care in these two groups, respectively, experienced:
Substantially reduced rates of severe asthma attacks, with a 65% and 59% average reduction over one year compared to placebo (0.24 and 0.31 events per year for Dupixent vs. 0.67 and 0.75 for placebo, respectively).
Improved lung function observed as early as two weeks and sustained for up to 52 weeks, measured by percent predicted FEV1 (FEV1pp).
At 12 weeks, patients taking Dupixent improved their lung function by 5.32 and 5.21 percentage points compared to placebo, respectively.
Improved asthma control, with 81% and 79% of patients reporting a clinically meaningful improvement at 24 weeks, based on disease symptoms and impact compared to 64% and 69% of placebo patients, respectively.
Improved health-related quality of life, with 73% and 73% of patients reporting a clinically meaningful improvement at 24 weeks, compared to 63% and 65% of placebo patients, respectively.
Reduced systemic corticosteroid use by an average of 66% and 59% over one year compared to placebo (0.27 and 0.35 courses per year for Dupixent vs. 0.81 and 0.86 for placebo, respectively).
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. The overall rates of adverse events were 83% for Dupixent and 80% for placebo. Adverse events that were more commonly observed with Dupixent compared to placebo included injection site reactions (18% Dupixent, 13% placebo), viral upper respiratory tract infections (12% Dupixent, 10% placebo) and eosinophilia (7% Dupixent, 1% placebo). Helminth infections were also more commonly observed with Dupixent in patients aged 6 to 11 years and were reported in 2% of Dupixent patients and 0% of placebo patients.
About the LIBERTY ASTHMA VOYAGE Trial
The Phase 3 randomized, double-blind, placebo-controlled trial evaluated the efficacy and safety of Dupixent (100 mg or 200 mg every two weeks, based on weight tier) combined with standard-of-care asthma therapy in 408 children aged 6 to 11 years with uncontrolled moderate-to-severe asthma. More than 90% of children in the trial had at least one concurrent atopic medical condition such as allergic rhinitis and atopic dermatitis.
The primary endpoint was the annualized rate of severe asthma exacerbations over one year, and the key secondary endpoint was the change from baseline in percentage of predicted pre-bronchodilator FEV1 (FEV1pp) at week 12. The 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. Additional secondary endpoints included responder rates for asthma control as measured by a 0.5 improvement on the Asthma Control Questionnaire-7 Interviewer Administered (ACQ-7-IA; 7-point scale) and health-related quality of life as measured by a 0.5 improvement on the Pediatric Asthma Quality of Life Questionnaire with Standardized Activities-Interviewer Administered (PAQLQ(S)-IA; 7-point scale).
