FDA grants priority review for Dupixent® (dupilumab) as potential treatment for adolescents with uncontrolled moderate-to-severe atopic dermatitis

Tuesday, November 6, 2018 7:00 am EST

Dateline:

PARIS and TARRYTOWN, NY

The U.S. Food and Drug Administration (FDA) has accepted for Priority Review the supplemental Biologics License Application (sBLA) for Dupixent® (dupilumab) in adolescent patients 12 to 17 years of age with moderate-to-severe atopic dermatitis, whose disease was inadequately controlled with topical therapies or for whom topical treatment was medically inadvisable. Currently, there are no FDA-approved systemic biologic medicines to treat adolescents with moderate-to-severe atopic dermatitis. The target action date for the FDA decision is March 11, 2019.

The sBLA is supported by data from a pivotal Phase 3 trial evaluating the efficacy and safety of Dupixent monotherapy in adolescent patients with moderate-to-severe atopic dermatitis, which were presented at the European Academy of Dermatology and Venereology in September 2018.

Dupixent works by inhibiting interleukin-4 and interleukin-13 (IL-4 and IL-13) signaling, which is one of the important contributors to Type 2 inflammation, a systemic response known to play a role in moderate-to-severe atopic dermatitis.

Dupixent is currently approved in the U.S. as a treatment for adults with moderate-to-severe atopic dermatitis whose disease is not adequately controlled with topical prescription therapies or when those therapies are not advisable; and as add-on maintenance treatment for patients 12 years and older with moderate-to-severe asthma with an eosinophilic phenotype or with oral corticosteroid-dependent asthma. In 2016, the FDA granted Breakthrough Therapy designation for Dupixent for the treatment of moderate-to-severe (adolescents 12 to 17 years of age) and severe (children 6 months to 11 years of age) atopic dermatitis not well controlled on topical prescription medications.

Dupixent is also approved for use in certain adult patients with moderate-to-severe atopic dermatitis in countries of the European Union, and other countries including Canada and Japan. In the U.S., more than 60,000 adult patients with atopic dermatitis have been prescribed Dupixent to date.

The safety and efficacy of Dupixent in adolescents with atopic dermatitis have not been fully evaluated by any regulatory authority.

Dupilumab ongoing development program

Sanofi and Regeneron are also studying dupilumab in a broad range of clinical development programs for diseases driven by allergic and other Type 2 inflammation, including pediatric (6 months to 11 years of age) atopic dermatitis (Phase 3), pediatric asthma (Phase 3), chronic rhinosinusitis with nasal polyps (Phase 3), eosinophilic esophagitis (Phase 3), grass allergy (Phase 2) and peanut allergy (Phase 2). A future trial is planned for chronic obstructive pulmonary disease. Dupixent is also being studied in combination with REGN-3500, which targets IL-33. These potential uses are investigational and the safety and efficacy have not been evaluated by any regulatory authority. Dupilumab is being jointly developed by Sanofi and Regeneron under a global collaboration agreement.

IMPORTANT SAFETY INFORMATION AND INDICATIONS

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 (if you also have atopic dermatitis)
  • have a parasitic (helminth) infection
  • are taking oral, topical, or inhaled corticosteroid medicines. Do not stop taking your corticosteroid medicines unless instructed by your healthcare provider. This may cause other symptoms that were controlled by the corticosteroid medicine to come back.
  • 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. 
  • 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. If you are taking asthma medicines, do not change or stop your asthma medicine without talking to your healthcare provider. 

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. If you have atopic dermatitis, tell your healthcare provider if you have any new or worsening eye problems, including eye pain or changes in vision. 
  • Inflammation in 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 include injection site reactions, pain in the throat (oropharyngeal pain) and cold sores in your mouth or on your lips.  Eye and eyelid inflammation, including redness, swelling and itching have been seen in patients who have atopic dermatitis.

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. 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 adolescents with asthma 12 years of age and older, it is recommended that DUPIXENT be administered by or under supervision of an adult.

Please see accompanying full Prescribing Information including Patient Information.

INDICATIONS

DUPIXENT is a prescription medicine used:

  • to treat adults 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 18 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.
