Six Month Study Demonstrates Significant Reduction in Contrast-Enhancing Lesions Meeting Primary Endpoint
Safety and Tolerability Support Differentiated Product Profile
REDWOOD CITY, Calif., June 28, 2016 (GLOBE NEWSWIRE) -- Coherus BioSciences, Inc. (Nasdaq:CHRS), a leading global biosimilars company with late-stage clinical products, today announced that a study with CHS-131 in treatment-naïve, relapsing remitting multiple sclerosis (RRMS) subjects demonstrated approximately a 50% decrease in the incidence of new contrast-enhancing (CE) lesions over six months when compared to placebo. CHS-131 was generally well-tolerated and without evidence of immune suppression or the side-effects commonly seen in other oral multiple sclerosis (MS) therapies. CHS-131 is a novel, first-in-class, well-tolerated, once-daily, oral drug candidate for MS patients which has anti-inflammatory activity in the central nervous system (CNS) and crosses the blood-brain barrier.
“These are exciting results for a new drug with non-immunosuppressive activity that is well-tolerated by patients,” said Patricia G. Coyle, M.D., Vice Chair at State University of New York (SUNY) Stony Brook Neurosciences Institute. “This clearly warrants further clinical investigation.” Dr. Coyle is a well-known MS expert and was not a study investigator or a consultant to the company.
This Phase 2b trial was a randomized, double-blind, placebo-controlled clinical study that evaluated the efficacy, safety and tolerability of two orally administered doses (3 mg and 1 mg daily) of CHS-131 against placebo for six months in 227 subjects with RRMS. The primary endpoint of the trial was the reduction in the cumulative number of total CE lesions determined by magnetic resonance imaging (MRI) from baseline to week 24 of study treatment, a standard endpoint for Phase 2 trials in RRMS. Subjects were assessed clinically and by MRI monthly for six months. All MRIs were read in a blinded fashion at a U.S. imaging center. Patients on CHS-131 experienced a statistically significant reduction in CE lesions that was dose dependent, with the 3 mg dose resulting in a 46.3% reduction in CE lesions with a p-value of 0.01 compared to placebo.
The detailed results of the study are expected to be presented at a scientific conference later in 2016.
Safety and tolerability data from the trial provide support for a differentiated, potential best-in-class profile. The overall adverse event profile appeared relatively similar between the CHS-131 dose groups and placebo with no new safety signals for patients receiving CHS-131. The study is ongoing and part 2 is an open label safety extension in which clinical response, CE lesions on MRI, and safety will continue to be evaluated.
“We believe these results are consistent with a well-differentiated profile with strong commercial potential in the $20 billion MS market. CHS-131 is strategically synergistic with our biosimilar MS therapeutic area franchise and we see this asset as the cornerstone of our MS strategy. It is expected to be complementary with existing CNS therapies and the injectable protein product candidates in the Coherus MS biosimilar program. The product candidate is substantially Phase 3 ready in terms of preclinical toxicology. We will now be moving forward with our various MS biosimilar candidates,” said Denny Lanfear, President & Chief Executive Officer Coherus. “We are excited about these positive results as we continue to focus on execution in a transformative year for Coherus.”
CHS-131 is an anti-inflammatory molecule without immunosuppressive activity and has been studied in over 600 patients in other indications, as well as MS, and has been demonstrated to be generally well tolerated. Therefore, CHS-131 may be a candidate for first-line therapy alone or in combination with other MS disease modifying therapies, many of which are immunosuppressive.
Unlike CHS-131, many MS disease modifying therapies are designed to function by suppressing the immune response, both in the nervous system and throughout the body. This renders patients susceptible to certain opportunistic infections, malignancies and other side effects. In contrast, CHS-131 has potent anti-inflammatory effects without evidence of immunosuppression.
Coherus will hold a conference call on Tuesday, June 28, 2016 at 12:00 noon ET.
