E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objectives of Part 1 of the study are to compare the efficacy and safety of CHS 0214 manufactured in the EU, to Enbrel (EU) at 24 weeks in subjects with RA who have an inadequate response to methotrexate and no more than 3 other non-biologic disease modifying anti rheumatic drugs and who are naïve to biologic therapies.
The objectives of Part 2 of the study are to evaluate the longer term safety and the durability of response to open-label CHS 0214.
