Percentage of Participants With American College of Rheumatology (ACR) 20 Response |
ACR20 response: greater than or equal to (=) 20% improvement in tender or swollen joint counts and 20% improvement in 3 of the following 5 criteria: 1) Physician's global assessment of disease activity, 2) participant assessment of disease activity, 3) Patient Assessment of Pain (visual analog scale [VAS]), 4) participant assessment of functional disability via a Health Assessment Questionnaire (HAQ), and 5) erythrocyte sedimentation rate (ESR) at each visit. |

Percentage of Participants Achieving Disease Activity Score 28 (DAS28) Remission (DAS28 < 2.6) |
The DAS28 was derived from assessments of erythrocyte sedimentation rate (ESR) measured in millimeters per hour (mm/h), tender joint count on 28 joints (TJC28), swollen joint count on 28 joints (SJC28), and Patient's Global Assessment of disease activity according to 100--millimeter (mm) Visual Analog Scale (VAS). DAS28 score was calculated as [0.56 × square root of TJC] + [0.28 × square root of SJC] + [0.70 × natural log (ESR)] + [0.014 × VAS]. DAS28 score could range from 0 to 10, where higher score represented higher disease activity. The change from Week 24 to Week 40 was averaged among all participants, where negative changes indicated an improvement in disease activity. |

Change in DAS28 From Baseline |
The DAS28 was derived from assessments of erythrocyte sedimentation rate (ESR) measured in millimeters per hour (mm/h), tender joint count on 28 joints (TJC28), swollen joint count on 28 joints (SJC28), and Patient's Global Assessment of disease activity according to 100--millimeter (mm) Visual Analog Scale (VAS). DAS28 score was calculated as [0.56 × square root of TJC] + [0.28 × square root of SJC] + [0.70 × natural log (ESR)] + [0.014 × VAS]. DAS28 score could range from 0 to 10, where higher score represented higher disease activity. The change from Week 24 to Week 40 was averaged among all participants, where negative changes indicated an improvement in disease activity. The change is the difference in adjusted mean change from baseline in DAS28 between ocrelizumab 400 x 1 and ocrelizumab 200 x 2 with placebo. |

Percentage of Participants Achieving an ACR50 Response |
The ACR50 response at any time was defined as >/=50% improvement compared to baseline in TJC (assessed on 68 joints) and SJC (assessed on 66 joints); and 50% improvement compared to baseline in 3 of the following 5 criteria, respectively: 1) Patient's global assessment of disease activity according to 100-mm VAS, 2) Physician's global assessment of disease activity according to 100-mm VAS, 3) participant's global assessment of pain according to 100-mm VAS, 4) Participant's assessment of functional ability via HAQ-DI, and 5) Acute phase reactant (ESR in mm/h or CRP in mg/dL). |

Change From Baseline in the Individual Parameters of the ACR Core Set |
Change in the scores of the following parameters of ACR core set relative to respective baseline scores was measured: SJC (28 and 66 joints) and TJC (28 and 66 joints), patient's global assessment and physician's global assessment based on disease activity (both are expressed by VAS [0 = no disease activity to 100 = maximum disease activity]), HAQ (based on HAQ disability index [HAQDI]) which included 8 domains (dressing/grooming, arising, eating, walking, hygiene, reach, grip; common daily activities) rated on a 4-point scale (0=without any difficulty to 3=unable to do), where the sum of scores was divided by the number of domains with a score for a total possible score of 0 (best) to 3 (worst), pain assessment using a VAS ranging from score 0 (no pain) to 100 (unbearable pain). |

Change in FACIT-F Fatigue Assessment From Baseline |
The FACIT-Fatigue score was calculated according to a 13-item questionnaire that assesses self-reported fatigue and its impact upon daily activities and function. 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 participants 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-Fatigue score for a total possible score of 0 (worse score) to 52 (better score). Clinically relevant improvement is defined as a greater than or equal to (=)5-point change from Baseline. |
