REGN3500 (SAR440340) monotherapy significantly reduced loss of asthma control and improved lung function compared to placebo


Sanofi and Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced that a Phase 2 proof-of-concept trial evaluating the investigational IL-33 antibody REGN3500 (SAR440340) met the primary endpoint of improvement in loss of asthma control when comparing REGN3500 monotherapy to placebo. The trial also met a key secondary endpoint, demonstrating REGN3500 monotherapy significantly improved lung function compared to placebo.

In the trial, the greatest improvement was observed in patients with blood eosinophil levels =300 cells/microliter. Patients treated with Dupixent® (dupilumab) monotherapy did numerically better than REGN3500 across all endpoints, although the trial was not powered to show differences between active treatment arms. The combination of REGN3500 and Dupixent also did not demonstrate increased benefit compared to Dupixent monotherapy in this trial. More detailed results will be presented at an upcoming medical meeting

“This trial suggests that REGN3500 may provide an alternative targeted approach for patients suffering from asthma,” said George D. Yancopoulos, M.D., Ph.D., President and Chief Scientific Officer at Regeneron. “We look forward to working with Sanofi to advance REGN3500 through our asthma clinical trial program, as well as continuing our ongoing trials in atopic dermatitis and chronic obstructive pulmonary disease.”

Adverse events (AEs) occurred in 61.6% of patients who received REGN3500, 66.2% of patients receiving both REGN3500 and Dupixent, 56.8% of patients who received Dupixent and 64.9% of patients who received placebo. The incidence of serious AEs and AEs leading to treatment discontinuations was low.

Despite standard-of-care treatment with inhaled corticosteroid (ICS) and long-acting beta-agonist (LABA) therapy, people with moderate-to-severe asthma often have inadequately controlled, persistent symptoms that may make them suitable for treatment with a biologic therapy. These people live with coughing, wheezing and difficulty breathing, and are at risk of severe asthma attacks that may require emergency room visits or hospitalizations

“Asthma is a heterogeneous disease and not everyone experiences it in the same way. Therefore, there is value in evaluating new therapies with distinct and novel mechanisms such as anti-IL-33,” said Steve Pascoe, M.D., Head of Immuno-Inflammation Development at Sanofi. “We have ongoing studies for SAR440340 in atopic dermatitis and chronic obstructive pulmonary disease. We will evaluate the results of these studies as well as the findings in asthma to determine the best path forward for this therapy.”

REGN3500 is a fully-human monoclonal antibody that inhibits interleukin-33 (IL-33), a protein that is believed to play a key role in type 1 and type 2 inflammation. Preclinical research showed REGN3500 blocked several markers of both types of inflammation. In moderate-to-severe asthma, there can be multiple sources of underlying inflammation that new therapies may help address.


About the Phase 2 Trial

The trial was a randomized, double-blind, placebo-controlled, 12-week proof-of-concept trial that enrolled 296 adult patients with moderate-to-severe asthma who were not well controlled on LABA and ICS therapy. Patients were randomized into four treatment groups: REGN3500 plus placebo, REGN3500 plus Dupixent, Dupixent plus placebo, and placebo. All patients received fluticasone/salmeterol as the ICS/LABA maintenance therapy, which was withdrawn during the trial. At four weeks post-randomization, the LABA was withdrawn, and between six and nine weeks the ICS was tapered to withdrawal. Patients continued without ICS/LABA maintenance therapy until 12 weeks. If a patient experienced loss of asthma control (LOAC) during the trial, they resumed their prescreening ICS/LABA maintenance therapy and entered the safety follow-up period.

The primary endpoint was the proportion of patients who experienced LOAC on REGN3500 with or without Dupixent, compared to placebo.


About the REGN3500 (SAR440340) Development Program

Regeneron and Sanofi are currently studying REGN3500 in respiratory and dermatological diseases where inflammation is thought to play an underlying role. REGN3500 is being studied in Phase 2 trials for asthma, chronic obstructive pulmonary disease and atopic dermatitis. These potential uses are investigational and the safety and efficacy have not been evaluated by any regulatory authority. REGN3500 was invented using Regeneron's proprietary VelocImmune® technology that yields optimized fully-human antibodies, and is being developed jointly by Regeneron and Sanofi as part of a global collaboration agreement.


About Dupixent® (dupilumab)

Dupixent is a fully-human monoclonal antibody specifically designed to inhibit the signaling of interleukin-4 (IL-4) and interleukin-13 (IL-13), two key proteins that may play a central role in the type 2 inflammation that underlies asthma as well as other allergic and atopic diseases.

Dupixent is approved in the U.S. for the treatment of people 12 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; and for use 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 is also approved for certain patients with moderate-to-severe atopic dermatitis and severe asthma in the European Union and Japan.

In addition to the currently approved indications, Sanofi and Regeneron are also studying dupilumab for additional diseases driven by allergic and other type 2 inflammation, including chronic rhinosinusitis with nasal polyps (Phase 3 completed), pediatric asthma and atopic dermatitis (6 to 11 years of age, Phase 3), pediatric atopic dermatitis (6 months to 5 years of age, Phase 2/3), eosinophilic esophagitis (Phase 3), chronic obstructive pulmonary disease (Phase 3), and food and environmental allergies (Phase 2). These potential uses, and its use in combination with REGN3500, are investigational and the safety and efficacy have not been evaluated by any regulatory authority.
