TARRYTOWN, N.Y. and PARIS, Feb. 18, 2022 /PRNewswire/ —
In a Phase 3 trial in patients refractory to omalizumab, Dupixent did not reach statistical significance in interim analysis despite numeric improvements observed across key endpoints; trial will be stopped due to futility
Positive results from a previous Phase 3 trial in biologic-naïve patients showed Dupixent significantly reduced itch and hives compared to standard-of-care antihistamines alone
Companies remain committed to advancing Dupixent for patients with chronic spontaneous urticaria uncontrolled on antihistamines and are evaluating next steps
Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Sanofi today announced a Phase 3 trial (CUPID STUDY B) evaluating Dupixent® (dupilumab) in patients with chronic spontaneous urticaria (CSU) will stop due to futility, based on a pre-specified interim analysis. The trial, which assessed Dupixent added to antihistamines in patients refractory to omalizumab at 24 weeks, showed positive numerical trends in reducing itch and hives (the primary endpoints) but did not meet statistical significance during an interim analysis conducted by an independent review committee. The safety data were generally consistent with the known safety profile of Dupixent in its approved indications.
The LIBERTY-CUPID pivotal program was initiated in 2020 with an accelerated direct-to-Phase 3 strategy. The previously reported Phase 3 trial, which evaluated a different group of patients who were biologic-naïve (i.e., not previously treated with omalizumab), met its primary and all key secondary endpoints at 24 weeks, showing that adding Dupixent to standard-of-care antihistamines significantly reduced itch and hives compared to antihistamines alone. The companies remain committed to advancing Dupixent for patients with CSU uncontrolled on antihistamines and are evaluating next steps.
“Chronic spontaneous urticaria is a very complex disease, and these data add to the body of evidence assessing the underlying drivers of disease burden, including the potential role of interleukin-4 and interleukin-13,” said George D. Yancopoulos, M.D., Ph.D., President and Chief Scientific Officer at Regeneron. “While Dupixent did not show a significant benefit in the most difficult-to-treat patients who remain refractory to all approved medicines, we are carefully assessing the potential role of Dupixent in CSU based on the success of the first Phase 3 trial in biologic-naïve patients, where Dupixent nearly doubled the reduction in itch and urticaria activity.”
Detailed results from the first trial will be presented at the AAAAI Annual Meeting later this month, and the companies expect to share results from the second trial in a scientific forum. Regeneron and Sanofi are rapidly advancing a broad clinical development program to evaluate Dupixent in diseases with significant unmet need and where type 2 inflammation may play a role. The companies also recently announced positive Phase 3 results in eosinophilic esophagitis (EoE) and prurigo nodularis (PN), and additional results are also expected later this year in pediatric EoE, chronic inducible urticaria-cold (CindU), and hand and foot atopic dermatitis.
The potential use of Dupixent in CSU, EoE, PN, CindU, and hand and foot atopic dermatitis are currently under clinical development, and the safety and efficacy have not been fully evaluated by any regulatory authority.
About Chronic Spontaneous Urticaria
CSU is a chronic inflammatory skin disease characterized by the sudden onset of hives on the skin and/or swelling deep under the skin. Despite standard-of-care treatment, people with CSU often experience symptoms including a persistent itch or burning sensation, which can be debilitating and significantly impact quality of life. Swelling often occurs on the face, hands and feet, but can also affect the throat and upper airways.
About the Dupixent Phase 3 CSU Program (LIBERTY-CUPID)
Study B of the Phase 3 randomized, double-blind, placebo-controlled LIBERTY-CUPID clinical program evaluated the efficacy and safety of Dupixent in 83 patients with CSU aged 12 to 80 years who remained symptomatic despite standard-of-care treatment and were intolerant or incomplete responders to omalizumab. During the 24-week treatment period, patients received Dupixent or placebo every two weeks added to standard-of-care antihistamines.
The primary endpoints assessed the change from baseline in itch (measured by the weekly itch severity score) and the change from baseline in itch and hives (measured by the weekly urticaria activity score) at 24 weeks.
Study A of clinical program evaluated the efficacy and safety of Dupixent as an add-on therapy to standard-of-care antihistamines compared to antihistamines alone in 138 patients aged 6 years and older with CSU who remained symptomatic despite antihistamine use and were not previously treated with omalizumab.
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. IL-4 and IL-13 are key and central drivers of the type 2 inflammation that plays a major role in atopic dermatitis, asthma and chronic rhinosinusitis with nasal polyposis (CRSwNP).
Dupixent is currently approved in the U.S., Europe, Japan and other countries around the world for use in specific patients with moderate-to-severe atopic dermatitis, as well as certain patients with asthma or CRSwNP in different age populations. Dupixent is also approved in one or more of these indications in more than 60 countries around the world, and more than 350,000 patients have been treated globally.
About Regeneron’s VelocImmune Technology
Regeneron’s VelocImmune technology utilizes a proprietary genetically engineered mouse platform endowed with a genetically humanized immune system to produce optimized fully human antibodies. When Regeneron’s President and Chief Scientific Officer George D. Yancopoulos was a graduate student with his mentor Frederick W. Alt in 1985, they were the first to envision making such a genetically humanized mouse, and Regeneron has spent decades inventing and developing VelocImmune and related VelociSuite® technologies. Dr. Yancopoulos and his team have used VelocImmune technology to create approximately a quarter of all original, FDA-approved or authorized fully human monoclonal antibodies currently available. This includes Dupixent, REGEN-COV® (casirivimab and imdevimab), Libtayo® (cemiplimab-rwlc), Praluent® (alirocumab), Kevzara® (sarilumab), Evkeeza® (evinacumab-dgnb) and Inmazeb™ (atoltivimab, maftivimab and odesivimab-ebgn).
Dupilumab Development Program
Dupilumab is being jointly developed by Regeneron and Sanofi under a global collaboration agreement. To date, dupilumab has been studied across 60 clinical trials involving more than 10,000 patients with various chronic diseases driven in part by type 2 inflammation.
In addition to the currently approved indications, Regeneron and Sanofi are studying dupilumab in a broad range of diseases driven by type 2 inflammation or other allergic processes, including CSU (Phase 3), pediatric atopic dermatitis (6 months to 5 years of age, Phase 3), chronic obstructive pulmonary disease with evidence of type 2 inflammation (Phase 3), EoE (Phase 3), bullous pemphigoid (Phase 3), PN (Phase 3), CindU (Phase 3), chronic rhinosinusitis without nasal polyposis (Phase 3), allergic fungal rhinosinusitis (Phase 3), allergic bronchopulmonary aspergillosis (Phase 3) and peanut allergy (Phase 2). These potential uses of dupilumab are currently under clinical investigation, and the safety and efficacy in these conditions have not been fully evaluated by any regulatory authority.
DUPIXENT is a prescription medicine used:
- to treat adults and children 6 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 6 years 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.
IMPORTANT SAFETY INFORMATION FOR U.S. PATIENTS

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. DUPIXENT can cause allergic reactions that can sometimes be severe. Stop using DUPIXENT and tell your healthcare provider or get emergency help right away if you get any of the following signs or symptoms: breathing problems or wheezing, swelling of the face, lips, mouth, tongue or throat, fainting, dizziness, feeling lightheaded, fast pulse, fever, hives, joint pain, general ill feeling, itching, skin rash, swollen lymph nodes, nausea or vomiting, or cramps in your stomach-area.
- Eye problems. Tell your healthcare provider if you have any new or worsening eye problems, including eye pain or changes in vision, such as blurred vision. Your healthcare provider may send you to an ophthalmologist for an exam if needed.
- 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, chest pain, worsening shortness of breath, a feeling of pins and needles or numbness of your arms or legs, or persistent fever.
- Joint aches and pain. Some people who use DUPIXENT have had trouble walking or moving due to their joint symptoms, and in some cases needed to be hospitalized. Tell your healthcare provider about any new or worsening joint symptoms. Your healthcare provider may stop DUPIXENT if you develop joint symptoms
The most common side effects include:
- Atopic dermatitis: injection site reactions, eye and eyelid inflammation, including redness, swelling, and itching, sometimes with blurred vision, and cold sores in your mouth or on your lips.
- Asthma: injection site reactions, pain in the throat (oropharyngeal pain), high count of a certain white blood cell (eosinophilia), and parasitic (helminth) infections.
- Chronic rhinosinusitis with nasal polyposis: injection site reactions, eye and eyelid inflammation, including redness, swelling, and itching, sometimes with blurred vision, 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 by your healthcare provider. It’s an injection given under the skin (subcutaneous injection). Your healthcare provider will decide if you or your caregiver can inject DUPIXENT. Do not try to prepare and inject DUPIXENT until you or your caregiver have been trained by your healthcare provider. In children 12 years of age and older, it’s recommended DUPIXENT be administered by or under supervision of an adult. In children under 12 years of age, DUPIXENT should be given by a caregiver.
