| Secondary | Percentage of Participants Meeting European League Against Rheumatism (EULAR) Response Criteria During the Initial Treatment Period | The EULAR response criteria were based on the assessment of disease activity using the DAS28. The EULAR response criteria included not only change in disease activity but current disease activity. To be classified as responders, participants had to have a significant change in DAS28 and a low current disease activity. There were 4 categories of EULAR response rates: good, moderate, good/moderate, and none. The DAS28 scoring used 4 core components: SJC, TJC, Patient's Global Assessment of Disease Activity, and ESR. The DAS28 has a continuous scale ranging from 0 to 9.4. The level of disease activity was interpreted as low (DAS28 score less than or equal to [≤]3.2), moderate (DAS28 score greater than [>]3.2 but ≤5.1), or high (DAS28 score >5.1). A DAS28 score <2.6 corresponded to a state of remission according to American Rheumatism Association criteria. | | Posted | | Number | | percentage of participants | | Weeks 4, 12, 24, 36, and 48 of Initial treatment period | | | | ID | Title | Description |

| Secondary | Change From Baseline in CRP During the Initial Treatment Period | CRP levels were measured in milligrams/liter (mg/L) and were used to determine the acute phase response. A reduction in CRP levels is considered an improvement; normal reference range ≤10 mg/L. | ITT Population; n=number of participants assessed for the specified parameter at a given visit. | Posted | | Mean | Standard Deviation | mg/L | | Weeks 4, 12, 24, 36, and 48 of Initial treatment period | | | | ID | Title | Description |

| OG000 | Initial Treatment Period: Rituximab + MTX | Participants received rituximab 1000 mg IV and methylprednisolone 100 mg IV on Days 1 and 15. Participants should have been receiving a stable dose (for at least 12 weeks prior to Screening) of MTX 10-25 mg/week and a stable dose of folate (≥5 mg/week) given as either a single weekly dose or as divided daily doses (per investigator discretion). |

| Secondary | Percentage of Participants With Disease Remission According to DAS28 in the Initial Treatment Period | The DAS28 scoring used 4 core components: SJC, TJC, Patient's Global Assessment of Disease Activity, and ESR. The DAS28 has a continuous scale ranging from 0 to 9.4. The level of disease activity was interpreted as low (DAS28 score ≤3.2), moderate (DAS28 score >3.2 but ≤5.1), or high (DAS28 score >5.1). A DAS28 score ≤2.6 corresponded to a state of remission according to American Rheumatism Association criteria. | | Posted | | Number | | percentage of participants | | Weeks 4, 12, 24, 36, and 48 of Initial treatment period | | | | ID | Title | Description |

| Secondary | Change From Baseline in Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) Total Score During the Initial Treatment Period | Participant fatigue was evaluated using the FACIT-F scale, a 13-item questionnaire in which the participants were requested to score each item on a 5-point scale. The FACIT-F scores ranged from 0 to 52, with higher scores representing less fatigue. Score changes of 4 points or more were considered clinically meaningful. The total score was a summation of all 13 items, where 2 of the positive items (I have energy; I am able to do my usual activities) were reversed for scoring. | ITT Population; n=number of participants assessed for the specified parameter at a given visit. | Posted | | Mean | Standard Deviation | scores on a scale | | Weeks 4, 12, 24, 36, and 48 of Initial treatment period | | | | ID | Title | Description |
