PARIS and TARRYTOWN, N.Y. – October 13, 2020 – A pivotal Phase 3 trial of Dupixent® (dupilumab) met its primary and all key secondary endpoints in children aged 6 to 11 years with uncontrolled moderate-to-severe asthma. In a broad type 2 inflammatory asthma patient population, defined as having elevated eosinophils (EOS) or elevated fractional exhaled nitric oxide (FeNO), Dupixent added to standard of care significantly reduced asthma attacks (exacerbations) and improved lung function, as early as two weeks after the first dose, compared to standard of care alone. More than 90% of children in the trial had at least one concurrent type 2 inflammatory condition including atopic dermatitis and eosinophilic esophagitis. Safety results from the clinical trial were generally consistent with the known safety profile of Dupixent in patients aged 12 years and older with moderate-to-severe asthma.
“Children with uncontrolled moderate-to-severe asthma often struggle to breathe, largely because of their impaired lung function, and this can have a serious impact on their quality of life. It not only reduces their ability to participate in day-to-day activities, but can also take a huge emotional toll on the child and their family,” said John Reed, M.D., Ph.D., Global Head of Research and Development at Sanofi. “Dupixent is the only biologic shown in a controlled Phase 3 trial to improve lung function in children, which is generally consistent with results seen in the adolescent and adult trials. These positive data are especially encouraging for younger children who are struggling to manage their uncontrolled asthma.”
Despite standard-of-care therapy such as inhaled corticosteroids (ICS), children with uncontrolled moderate-to-severe asthma continue to experience symptoms such as coughing, wheezing, and difficulty breathing, and are at risk of severe asthma attacks.
For these children, this often leads to frequent hospitalizations and emergency room visits requiring use of systemic corticosteroids which can carry significant risks when used long-term. Uncontrolled asthma can cause children to miss school, and can interfere with physical activity and routine tasks including walking up stairs and playing sports. In the U.S., there are approximately 75,000 children 6-11 years old with uncontrolled moderate-to-severe asthma, and many more of these children worldwide.
“Children with moderate-to-severe asthma live with a heavy and unpredictable disease burden. Even while taking maximum treatments including inhaled corticosteroids, they suffer from multiple asthma attacks each year that may require hospitalization,” said George D. Yancopoulos, M.D., Ph.D., President and Chief Scientific Officer of Regeneron. “These impressive Phase 3 data in children with asthma show Dupixent significantly reduced annual severe asthma attacks and also improved lung function consistently across patients with markers of type 2 inflammation.”
The primary endpoint assessed the annualized rate of severe asthma attacks in two primary pre-specified populations: patients with baseline blood EOS ≥300 cells/μl and patients with markers of type 2 inflammation (FeNO ≥20 ppb or EOS ≥150 cells/μl). Across these two patient groups respectively, those who added Dupixent (100 mg or 200 mg every two weeks, based on weight) to standard of care experienced:
- Reduced rate of severe asthma attacks, with a 65% (p<0.0001) and 59% (p<0.0001) 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 at 12 weeks compared to baseline by 10.15 and 10.53 percentage points for Dupixent vs. 4.83 and 5.32 percentage points for placebo (least squares mean difference for Dupixent vs. placebo of 5.3 and 5.2 percentage points, p=0.0036 and p=0.0009), respectively, as measured by percent predicted FEV1 (FEV1pp). FEV1pp is a common endpoint in pediatric asthma trials to evaluate a patient’s change in lung function compared to their predicted lung function based on a number of factors including age, height and sex, to account for children’s growing lung capacity at different stages of development. This clinically meaningful improvement in lung function was observed as early as two weeks and was sustained for up to 52 weeks.
The safety results from the trial were generally consistent with the known safety profile of Dupixent in patients aged 12 years and older with moderate-to-severe asthma. Over one year, overall rates of adverse events were 83% for Dupixent and 80% for placebo. Adverse events that were most commonly observed with Dupixent versus placebo included injection site reactions (18% for Dupixent and 13% for placebo), viral upper respiratory tract infections (12% for Dupixent and 10% for placebo), and eosinophilia (6% for Dupixent and 1% for placebo).
Dupixent is a fully-human monoclonal antibody that inhibits the signaling of the interleukin-4 (IL-4) and interleukin-13 (IL-13) proteins. Data from Dupixent clinical trials have shown that IL-4 and IL-13 are key drivers of the type 2 inflammation that plays a major role in asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), atopic dermatitis and eosinophilic esophagitis.
About the LIBERTY ASTHMA VOYAGE Trial
The Phase 3, randomized, double-blind, placebo-controlled trial evaluated the efficacy and safety of Dupixent in addition to standard-of-care maintenance therapy of medium-dose inhaled corticosteroid (ICS) with a second controller medication or high-dose ICS with or without a second controller medication. The trial enrolled 408 children aged 6 to <12 years old with uncontrolled moderate-to-severe asthma. Primary analyses were based on 259 patients with baseline EOS ≥300 cells/µl and 350 patients with markers of type 2 inflammation (baseline EOS ≥150 cells/μl or FeNO ≥20 ppb). There was no minimum biomarker requirement for enrollment.
During the 52-week treatment period, patients received subcutaneous injections of Dupixent 100 mg or 200 mg every two weeks, based on weight (100 mg for ≤30 kg, 200 mg for >30 kg), or placebo every two weeks.
Dupixent is approved in the U.S. to treat patients aged 6 years and older with moderate-to-severe atopic dermatitis that is not well controlled with prescription therapies used on the skin (topical), or who cannot use topical therapies; for use with other asthma medicines for the maintenance treatment of moderate-to-severe eosinophilic or oral steroid dependent asthma in patients aged 12 years and older whose asthma is not controlled with their current asthma medicines; and for use with other medicines for the maintenance treatment of CRSwNP in adults whose disease is not controlled. In adolescents 12 years of age or older, it is recommended that Dupixent be administered by or under the supervision of an adult. In children younger than 12 years of age, Dupixent should be administered by a caregiver.
Outside of the U.S., Dupixent is approved for specific patients with moderate-to-severe atopic dermatitis and certain patients with asthma in a number of other countries around the world, including the EU and Japan. Dupixent is also approved in the EU and Japan to treat certain adults with severe CRSwNP.
Across all approved indications globally, more than 170,000 patients have been treated with Dupixent.
Dupilumab Development Program
To date, dupilumab has been studied in more than 10,000 patients across 50 clinical trials in various chronic diseases driven by type 2 inflammation. In addition to the currently approved indications, Sanofi and Regeneron are studying dupilumab in a broad range of diseases driven by type 2 inflammation or other allergic processes, including pediatric asthma (6 to 11 years of age, Phase 3), pediatric atopic dermatitis (6 months to 5 years of age, Phase 3), eosinophilic esophagitis (Phase 3), chronic obstructive pulmonary disease (Phase 3), bullous pemphigoid (Phase 3), prurigo nodularis (Phase 3), chronic spontaneous urticaria (Phase 3), and food and environmental allergies (Phase 2). These potential uses are investigational, and the safety and efficacy of dupilumab in these conditions have not been evaluated by any regulatory authority. Dupilumab is being jointly developed by Regeneron and Sanofi under a global collaboration agreement.
DUPIXENT is a prescription medicine used:
- to treat people aged 6 years 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 years of age.
- with other asthma medicines for the maintenance treatment of moderate-to-severe eosinophilic or oral steroid dependent 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.
- 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.
IMPORTANT SAFETY INFORMATION FOR U.S. PATIENTS
Do not use if you are allergic to dupilumab or to any of the ingredients in DUPIXENT®.
Before using DUPIXENT, tell your healthcare provider about all your medical conditions, including if you:
- have eye problems
- have a parasitic (helminth) infection
- are scheduled to receive any vaccinations. You should not receive a “live vaccine” if you are treated with DUPIXENT.
- are pregnant or plan to become pregnant. It is not known whether DUPIXENT will harm your unborn baby.
o There is a pregnancy exposure registry for women who take DUPIXENT during pregnancy to collect information about the health of you and your baby. Your healthcare provider can enroll you or you may enroll yourself. To get more information about the registry call 1‑877-311-8972 or go to https://mothertobaby.org/ongoing-study/dupixent/.
- are breastfeeding or plan to breastfeed. It is not known whether DUPIXENT passes into your breast milk.
Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins and herbal supplements.
Especially tell your healthcare provider if you are taking oral, topical, or inhaled corticosteroid medicines; have asthma and use an asthma medicine; or have atopic dermatitis or CRSwNP, and also have asthma. Do not change or stop your corticosteroid medicine or other asthma medicine without talking to your healthcare provider. This may cause other symptoms that were controlled by the corticosteroid medicine or other asthma medicine to come back.
DUPIXENT can cause serious side effects, including:
- Allergic reactions (hypersensitivity), including a severe reaction known as anaphylaxis. Stop using DUPIXENT and tell your healthcare provider or get emergency help right away if you get any of the following symptoms: breathing problems, fever, general ill feeling, swollen lymph nodes, swelling of the face, mouth and tongue, hives, itching, fainting, dizziness, feeling lightheaded (low blood pressure), joint pain, or skin rash.
- Eye problems. Tell your healthcare provider if you have any new or worsening eye problems, including eye pain or changes in vision.
- Inflammation of your blood vessels. Rarely, this can happen in people with asthma who receive DUPIXENT. This may happen in people who also take a steroid medicine by mouth that is being stopped or the dose is being lowered. It is not known whether this is caused by DUPIXENT. Tell your healthcare provider right away if you have: rash, shortness of breath, persistent fever, chest pain, or a feeling of pins and needles or numbness of your arms or legs.
The most common side effects by indications are as follows:
- Atopic dermatitis: injection site reactions, eye and eyelid inflammation, including redness, swelling, and itching, and cold sores in your mouth or on your lips.
- Asthma: injection site reactions, pain in the throat (oropharyngeal pain), and high count of a certain white blood cell (eosinophilia).
- Chronic rhinosinusitis with nasal polyposis: injection site reactions, eye and eyelid inflammation, including redness, swelling, and itching, high count of a certain white blood cell (eosinophilia), trouble sleeping (insomnia), toothache, gastritis, and joint pain (arthralgia).
Tell your healthcare provider if you have any side effect that bothers you or that does not go away. These are not all the possible side effects of DUPIXENT. Call your doctor for medical advice about side effects. You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
Use DUPIXENT exactly as prescribed. Your healthcare provider will tell you how much DUPIXENT to inject and how often to inject it. DUPIXENT is an injection given under the skin (subcutaneous injection). If your healthcare provider decides that you or a caregiver can give DUPIXENT injections, you or your caregiver should receive training on the right way to prepare and inject DUPIXENT. Do not try to inject DUPIXENT until you have been shown the right way by your healthcare provider. In children 12 years of age and older, it is recommended that DUPIXENT be administered by or under supervision of an adult. In children younger than 12 years of age, DUPIXENT should be given by a caregiver.
