简要总结
This is a multi-center, randomized, double-blind, parallel-group study to evaluate the efficacy and safety of intravenous HS628 in combination with MTX versus Actemra in combination with MTX, in participants with moderate to severe active rheumatoid arthritis (RA) who have inadequate response to current MTX therapy. The study comprises a 24-week treatment phase, followed by a 4-week safety observation period.
