Paris, France and Tarrytown, NY - March 11, 2016 - Sanofi and Regeneron Pharmaceuticals, Inc. today announced that a Phase 3 monotherapy study met its primary endpoint demonstrating that sarilumab was superior to adalimumab (marketed by AbbVie as HUMIRA®) in improving signs and symptoms in patients with active rheumatoid arthritis (RA) at Week 24. The study, called SARIL-RA-MONARCH, also met important secondary endpoints including other measures assessing improvements in signs and symptoms of RA and physical function. Sarilumab is an investigational, human IL-6 receptor antibody.
"In this study, sarilumab monotherapy provided stronger efficacy than adalimumab monotherapy. Adalimumab is one of the most commonly used biologic medicines in RA," said Janet van Adelsberg, M.D., Senior Director, Clinical Sciences, Immunology and Inflammation, Regeneron. "This is the first time an IL-6 receptor blocker delivered subcutaneously has demonstrated superiority over adalimumab monotherapy in RA."
The SARIL-RA-MONARCH study enrolled 369 adult patients with active RA who were inadequate responders to, intolerant of, or inappropriate candidates for methotrexate (MTX). Patients were randomized to receive either subcutaneous sarilumab monotherapy (200 mg every 2 weeks) or adalimumab monotherapy (40 mg every 2 weeks); patients who did not respond adequately to adalimumab could increase to weekly dosing.
"Despite the availability of a wide range of treatment options, we believe that new therapies are needed to further address unmet needs of RA patients," said Dr. Simon Cooper, MBBS VP, Global Project Head, Immunology and Inflammation, Sanofi. "These data suggest that sarilumab, if approved, may be an option for patients unable to tolerate or take methotrexate, and we look forward to sharing further details at an upcoming medical congress."
The primary endpoint was change from baseline in DAS28-ESR at 24 weeks, which demonstrated a statistically significant difference in favor of sarilumab (-3.25 for sarilumab compared to -2.22 for adalimumab, p less than 0.0001). The study also met clinically important secondary endpoints including improvements in signs and symptoms of RA as measured by patients achieving a 20 percent improvement in the American College of Rheumatology (ACR) criteria (72 percent for sarilumab vs. 58 percent for adalimumab, p less than 0.01). Additional positive secondary endpoints included ACR50 and ACR70 response, and improvement in physical function, as measured by the Health Assessment Questionnaire - Disability Index (HAQ-DI) as compared to adalimumab (p less than 0.01 for all of these measures). DAS28-ESR is a measure of disease activity in RA, which includes the evaluation of 28 joints in the body for tenderness and swelling, a general health assessment, and ESR, a laboratory measure for inflammation.
The incidence of adverse events (64 percent for both groups), serious adverse events (5 percent for sarilumab vs. 7 percent for adalimumab), infections (29 percent for sarilumab vs. 28 percent for adalimumab), and serious infections (1 percent for both groups) were generally similar between groups. Neutropenia, which was not associated with infections, was more common with sarilumab (14 percent for sarilumab vs.1 percent for adalimumab), as has been seen in previous studies with IL-6 inhibitors. Injection site erythema (8 percent sarilumab vs. 3 percent adalimumab) was also more common with sarilumab.
About Sarilumab
Sarilumab is a human monoclonal antibody directed against the IL-6 receptor that inhibits the inflammatory activity in RA mediated by the IL-6 signaling pathway. IL-6 is the most abundant cytokine in the serum and synovial fluid of patients with RA, and levels of IL-6 correlate with both disease activity and joint destruction. 2
In January, the companies announced that the U.S. Food and Drug Administration (FDA) accepted for review the biologics license application (BLA) for sarilumab with a target action date of October 30, 2016. The BLA submission is supported by data from approximately 2,500 adults with active, moderate-to-severe RA who had an inadequate response to previous treatment regimens, including seven studies from the global SARIL-RA Phase 3 program. The outcome of SARIL-RA-MONARCH is not part of the ongoing review by the FDA. The regulatory submission is planned in the EU in Q3 2016.
The safety and efficacy of sarilumab have not been fully evaluated by any regulatory authority.
