Coherus Announces CHS-1420 Pharmacokinetic Clinical Bioequivalence Study Meets Primary Endpoint

19:00 EST 1 Mar 2017 | Globe Newswire

REDWOOD CITY, Calif., March 02, 2017 (GLOBE NEWSWIRE) -- Coherus BioSciences, Inc. (Nasdaq:CHRS), today announced that CHS-1420, its proposed biosimilar of adalimumab (Humira®), met the primary endpoint in a clinical pharmacokinetic (PK) bioequivalence study that compared CHS-1420 to Humira in healthy subjects.  The study met the criteria for clinical PK similarity on all prospectively defined PK endpoints: maximum serum concentration (Cmax), area under the time-concentration curve from first to last time point measured (AUC-0-last), and area under the time-concentration curve from first time point extrapolated to infinity (AUC0-inf).  The 90% confidence intervals of the geometric mean ratios for all PK endpoints fell well within the bioequivalence boundaries of 80% to 125%.  Both agents were well tolerated and there were no differential safety findings observed between the two agents in this study.

CHS-1420-03 was a randomized, double-blind, parallel-group study in healthy subjects designed to assess the PK bioequivalence of CHS-1420 to that of Humira by comparing relative bioavailability after sub-cutaneous administration of a single 40 mg dose.  The safety and tolerability of CHS-1420 was also evaluated.

“Positive results from this study are an essential global regulatory requirement to demonstrate PK bioequivalence on multiple prespecified primary PK endpoints between CHS-1420 and Humira,” said Barbara Finck, M.D., Chief Medical Officer of Coherus. “We are pleased to have achieved results which we believe represent a significant reduction in development program risk.”

“This is our second successful CHS-1420 PK study,” noted Denny Lanfear, President and Chief Executive Officer of Coherus. “Our ability to achieve these results gives us confidence that we can similarly complete future PK studies with modified formulations, anticipated to commence later in 2017.”
