Brief Summary

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.

• all non-biological agents DMARD except methotrexate should be discontinued for at least 2 weeks before random administration( In addition, leflunomide should be discontinued for ≥8 weeks, and at least 2 weeks before randomized administration if standard coletenide therapy or activated carbon elution has been followed; Discontinuation of sulfasalazine ≥4 weeks; Yunke withdrawal ≥12 weeks）;
