Momenta and Mylan Report Initial Results from Phase 1 Clinical Trial for M834, a Proposed Biosimilar of ORENCIA® (abatacept)


CAMBRIDGE, Mass. and HERTFORDSHIRE, United Kingdom and PITTSBURGH, Nov. 01, 2017 (GLOBE NEWSWIRE) -- Momenta Pharmaceuticals, Inc. (Nasdaq:MNTA) and Mylan N.V. (NASDAQ:MYL) (TASE:MYL), today announced that M834, a proposed biosimilar of ORENCIA (abatacept), did not meet its primary pharmacokinetic (PK) endpoints in the Phase 1 study to compare the pharmacokinetics, safety and immunogenicity of M834 to US- and EU-sourced ORENCIA in normal healthy volunteers. Momenta and Mylan continue to gather and analyze these data to inform next steps for the program.

"This was an unexpected result and we are disappointed with the outcome of this PK study," said Craig Wheeler, President and Chief Executive Officer of Momenta Pharmaceuticals. "We are in the process of gathering the full data set and will work with Mylan to fully analyze these data to better understand the study results and evaluate next steps for this program. We remain committed to executing on our biosimilar portfolio."

The Phase 1 study was a randomized, double-blind, three-arm, parallel group, single-dose subcutaneous administration clinical study to compare the pharmacokinetics, safety, and immunogenicity of M834, US-sourced ORENCIA, and EU-sourced ORENCIA in 243 normal healthy volunteers.
