| OG000 | Tocilizumab | Participants received tocilizumab 8 mg/kg IV once every 4 weeks and MTX 7.5 to 25 mg/week per investigator's discretion, or without MTX if intolerant) for up to 13 months. Participants also received GC (no product/dose limitation) until LDA (defined as DAS28-CRP ≤3.2), up to a maximum of 6 months. Once LDA achieved, GC was switched to MP tablets, PO. MP dose determined by recalculating original GC dose to obtain an equivalent MP dose (had to be ≥1 mg and ≤20 mg/day), which was administered for 4 weeks. If LDA continued after 4 weeks, MP dose was reduced over the following 6 months per protocol-defined dose reduction schedule to reach 0 mg within 6 months for a maximum duration of 7 months of MP treatment. |

| Secondary | VAS for Pain (VAS-Pain) During the Interventional Phase | Participants were asked to mark the line corresponding to the intensity of their pain on a 100-mm VAS, where 0=no pain and 100=worst possible pain.

| Secondary | Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) Score During the Interventional Phase | FACIT-F is a 13-item questionnaire. Participants scored each item on a 5-point scale: 0 (not at all) to 4 (very much). The larger the participant's response to the questions (with the exception of 2 negatively stated), the greater the participant's fatigue. For all questions, except for the 2 negatively stated ones, the code was reversed and a new score was calculated as (4 minus the participant's response). The sum of all responses resulted in the FACIT-F score for a total possible score of 0 (worse score) to 52 (better score).
