TARRYTOWN - Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) announced 24 abstracts on Dupixent (dupilumab) clinical data and real-world analyses in respiratory diseases will be presented at the American Thoracic Society (ATS) International Conference 2025 being held from May 18 to 21 in San Francisco, California.

The abstracts, presented in collaboration with Sanofi, demonstrate the benefit of targeting IL-4 and IL-13 to address type 2 inflammation in chronic obstructive pulmonary disease (COPD) and asthma - chronic respiratory diseases that can impair lung function and impact daily life.

'The data presented at ATS demonstrate Regeneron's commitment to advancing the scientific understanding of type 2 inflammation across chronic respiratory diseases to ultimately transform care and quality of life for as many appropriate patients as possible,' said Jennifer Maloney, M.D., Therapeutic Area Lead of Immune, Inflammation, and Infectious Disease Global Development at Regeneron. 'Among our 24 abstracts at ATS are the latest results from the Dupixent COPD program, which include new analyses of its impact on critical disease measures such as lung function in broad patient populations with type 2 inflammation. We also look forward to sharing new asthma insights in both adult and pediatric populations.'

COPD data assess Dupixent impact on lung function and exacerbations in COPD, including patients with or without emphysema

Notable abstracts in COPD will highlight new results from the pivotal landmark Phase 3 BOREAS and NOTUS trials, including analyses demonstrating Dupixent reduced exacerbations and improved lung function regardless of whether patients had emphysema. In the pivotal COPD trials, the majority of patients had chronic bronchitis (=95%) and =30% had emphysema. Additional data being presented also demonstrate Dupixent improved multiple spirometry measures of lung function that were sustained through 52 weeks, compared to placebo.

Furthermore, a late-breaking poster of a win-ratio post-hoc analysis will assess the likelihood of avoiding a composite of events including death, hospitalization, worsening symptoms and lung function decline in the COPD pivotal trials by comparing each patient on Dupixent to each patient on placebo.

The safety results from BOREAS and NOTUS COPD trials were generally consistent with the known safety profile of Dupixent in its other approved indications. In pooled data from both trials, the most common adverse events (AEs; =2%) more frequently observed with Dupixent than placebo were viral infection, headache, nasopharyngitis, back pain, diarrhea, arthralgia, urinary tract infection, local administration reaction, rhinitis, eosinophilia, toothache and gastritis.

Asthma data reinforce impact of Dupixent on mucus burden, exacerbations and disease control

A late-breaking poster on the VESTIGE imaging trial will highlight that Dupixent reduced mucus burden, compared to placebo, as measured by mucus plug scores and volume regardless of fractional exhaled nitric oxide (FeNO) levels. An analysis of the VOYAGE trial also shows that, in children aged 6 to 11 years, Dupixent reduced exacerbations and improved disease control regardless of how long they had the disease.

The safety results in the asthma trials were generally consistent with the known safety profile of Dupixent in moderate-to-severe asthma, with the addition of helminth infections in the VOYAGE trial. In VOYAGE, the most common AEs more frequently observed with Dupixent than placebo were injection site reactions, viral upper respiratory tract infections and eosinophilia. In VESTIGE, the most common AEs (=5%) more frequently observed with Dupixent than placebo included COVID-19 and injection site reactions.

Results will also be shared for the first time in an oral presentation from the Phase 2 AIRED trial evaluating the impact of Dupixent on lung function, exacerbations and health-related quality of life in adults and adolescents with allergic bronchopulmonary aspergillosis (ABPA) and asthma. ABPA is a progressive lung disease caused by hypersensitivity to a fungal microorganism that can live in the airways of patients with breathing disorders like asthma.

About Dupixent

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. The Dupixent development program has shown significant clinical benefit and a decrease in type 2 inflammation in Phase 3 trials, establishing that IL-4 and IL-13 are two of the key and central drivers of the type 2 inflammation that plays a major role in multiple related and often co-morbid diseases.

Dupixent has received regulatory approvals in more than 60 countries in one or more indications including certain patients with atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyps (CRSwNP), eosinophilic esophagitis (EoE), prurigo nodularis, chronic spontaneous urticaria (CSU) and chronic obstructive pulmonary disease (COPD) in different age populations. More than 1,000,000 patients are being treated with Dupixent globally.1

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 co-Founder, 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 a substantial proportion of all original, FDA-approved fully human monoclonal antibodies. This includes Dupixent (dupilumab), Libtayo (cemiplimab-rwlc), Praluent (alirocumab), Kevzara (sarilumab), Evkeeza (evinacumab-dgnb), Inmazeb (atoltivimab, maftivimab and odesivimab-ebgn) and Veopoz (pozelimab-bbfg). In addition, REGEN-COV (casirivimab and imdevimab) had been authorized by the FDA during the COVID-19 pandemic until 2024.

Dupilumab Development Program

Dupilumab is being jointly developed by Regeneron and Sanofi under a global collaboration agreement. To date, dupilumab has been studied across more than 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 in Phase 3 trials, including chronic pruritus of unknown origin, bullous pemphigoid and lichen simplex chronicus. 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.
