Study Details

Study Description

Brief Summary

This is a randomized, double-blind, multi-center, parallel-group study to evaluate the efficacy and safety of subcutaneous (SC) tocilizumab (162 milligrams [mg] every 2 weeks [Q2W]) given as monotherapy and in combination with MTX versus MTX given as monotherapy, in participants with moderate to severe active rheumatoid arthritis (RA) who have inadequate response to current DMARD therapy. The study comprises a 24-week double-blind treatment phase, followed by a 24-week extension phase.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Tocilizumab + MTX

Participants will receive tocilizumab SC injections Q2W along with MTX orally every week (QW) for 24-week double-blind treatment phase. Participants who complete the 24-week double-blind treatment phase may continue treatment until Week 48 in the extension phase, irrespective if they achieve or do not achieve DAS28 low activity (DAS28-ESR <= 3.2).

Drug: Tocilizumab
Participants will receive tocilizumab 162 mg given as 0.9 milliliter (mL) of a 180 mg/mL solution in a prefilled syringe, administered by SC injection Q2W.
Other Names:
  • RO4877533

    • Drug: MTX
    Participants will receive MTX stable doses at 10 to 25 mg orally.
    Experimental: Tocilizumab + Placebo Matched to MTX

    Participants will receive tocilizumab SC Q2W along with placebo matched to MTX for 24-week double-blind treatment phase.
