Update on ongoing Dupixent® (dupilumab) chronic spontaneous urticaria Phase 3 program

Update on ongoing Dupixent^® (dupilumab) chronic spontaneous urticaria Phase 3 program

 

• In a Phase 3 trial in patients refractory to omalizumab, Dupixent did not reach statistical significance in an 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
• Companies remain committed to advancing Dupixent for patients with chronic spontaneous urticaria uncontrolled on antihistamines and are evaluating next steps

 

PARIS and TARRYTOWN, N.Y., February 18, 2022. A Phase 3 trial (CUPID STUDY B) evaluating Dupixent^® (dupilumab) in patients with chronic spontaneous urticaria (CSU), who were refractory to omalizumab, will stop due to futility based on a pre-specified interim analysis. Although positive numerical trends in reducing itch and hives were observed, the results from the interim analysis did not demonstrate statistical significance for the primary endpoints. The analysis was conducted by an independent interim analysis review committee. In the trial, patients who were refractory to omalizumab treatment and uncontrolled on antihistamines received Dupixent plus standard of care compared to standard of care alone for 24 weeks. 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, 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.

“Although we are disappointed in these latest results, this interim analysis contributes to furthering our understanding of the role of type 2 inflammation in this subset of CSU patients who are refractory to all other approved therapies. Based on the results seen in our first Phase 3 trial, and the numerical trends observed in this interim analysis, we remain committed to advancing Dupixent as an option for patients suffering from CSU who are uncontrolled on anti-histamines. We look forward to discussing next steps with regulators.”

 

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. Sanofi and Regeneron 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 Program in CSU (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.

 

About Dupixent

 

Dupixent 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 rinusinusitis with nasal polyps (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.

 

Dupilumab Development Program

 

Dupilumab is being jointly developed by Sanofi and Regeneron 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, Sanofi and Regeneron are studying dupilumab in a broad range of diseases driven by type 2 inflammation or other allergic processes including chronic spontaneous urticaria (Phase 3), chronic inducible urticaria-cold (Phase 3), pediatric atopic dermatitis (6 months to 5 years of age, Phase 3), prurigo nodularis (Phase 3), eosinophilic esophagitis (Phase 3), chronic obstructive pulmonary disease with evidence of type 2 inflammation (Phase 3), bullous pemphigoid (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.
