| Primary | Percentage of Participants With Disease Activity Score 28 Joints (DAS28) Remission at Week 24 | The DAS28 score is a measure of the patient's disease activity calculated using the tender joint count (TJC) [28 joints], swollen joint count (SJC) [28 joints], patient's global assessment of disease activity [visual analog scale: 0=no disease activity to 100=maximum disease activity] and the erythrocyte sedimentation rate (ESR) for a total possible score of 0 to approximately 10. Scores below 2.6 indicate best disease control and scores above 5.1 indicate worse disease control. DAS28 Remission is defined as a DAS28 score < 2.6. | Intent-to-treat population included all randomized participants who received study drug. | Posted | | Number | | Percentage of participants | | Week 24 | | | | ID | Title | Description |

| OG000 | Tocilizumab + Methotrexate | Tocilizumab 8 mg/kg (up to 800 mg) intravenous (IV) once every 4 weeks + weekly oral methotrexate continuing at the patient's pre-study dose for 24 weeks.

Week 52 to Week 104, based on the DAS28 assessment, treatment was adjusted to one of four protocol specified treatment regimens: Treatment tapering, Continued treatment, Treatment intensification or Maintenance treatment.

| Secondary | Time to Drug-Free Remission | The time in days from initial study drug treatment to drug free remission that occurred when the participant was able to discontinue tocilizumab, methotrexate/placebo and open label disease-modifying antirheumatic drugs (DMARDS). | Participants from the Intent-to-treat population (all randomized participants who received study drug) with data available for this outcome measure.
