What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participant With Good or Moderate Response According to European League Against Rheumatism (EULAR) Response Criteria	The DAS28 score is a measure of the participant's disease activity. It is based on the tender joint count (28 joints), swollen joint count (28 joints), patient's global assessment of disease activity [visual analog scale: 0=no disease activity to 100=maximum disease activity], and ESR. DAS28 total scores range from 0 to 10. DAS28 <=3.2 indicates low disease activity, DAS28 >3.2 to 5.1 indicates moderate to high disease activity. A negative change from Baseline indicates improvement. The DAS28-based EULAR response criteria were used to measure individual response as none, good, and moderate, depending on the extent of change from baseline (CFB) and the level of disease activity reached. Good response: DAS28 <=3.2 and a CFB >1.2. Moderate response: DAS28 <=3.2 and CFB >0.6 to <=1.2, DAS28 >3.2 to <=5.1 and CFB >1.2 or >0.6 to <=1.2, DAS28 >5.1 and CFB >1.2. No response: DAS28 <=3.2 and CFB >=0.6, DAS28 >3.2 to <=5.1 and CFB <=0.6, DAS28 >5.1 and CFB >0.6 to <=1.2 or <=0.6.	Week 20
Change From Baseline in DAS28-ESR at Week 20	DAS28 was calculated from SJC and TJC using an assessment of 28 joints, the erythrocyte sedimentation rate (ESR) (milliliter per hour [ml/hr]), and Patient's Global Assessment (PGH) of disease activity [measured on a 0 to 100 millimeter (mm) Visual Analogue Scale (VAS) where 0=no disease activity and 100=worst disease activity]. DAS28 was calculated using the following formula: DAS28 = 0.56*square root (sqrt) (TJC28) + 0.28*sqrt(SJC28) + 0.70*natural logarithm (ln) (ESR) + 0.014*PGH of disease activity. Total score range: 0-10, with a higher score indicated more disease activity. DAS28 <=3.2 implied low disease activity, DAS >3.2 to 5.1 implied moderate disease activity and DAS >5.1 implied high disease activity, and DAS28 <2.6 = clinical remission.	Baseline and Week 20
Mean DAS28-ESR Score at Visit 4 (Week 20)	DAS28 was calculated from SJC and TJC using an assessment of 28 joints, the erythrocyte sedimentation rate (ESR) (milliliter per hour [ml/hr]), and Patient's Global Assessment (PGH) of disease activity (measured on a 0 to 100 mm Visual Analogue Scale [VAS] where 0=no disease activity and 100=worst disease activity). DAS28 was calculated using the following formula: DAS28 = 0.56*square root (sqrt) (TJC28) + 0.28*sqrt(SJC28) + 0.70*natural logarithm (ln) (ESR) + 0.014*PGH of disease activity. Total score range: 0-10, with a higher score indicated more disease activity. DAS28 <=3.2 implied low disease activity, DAS >3.2 to 5.1 implied moderate disease activity and DAS >5.1 implied high disease activity, and DAS28 <2.6 = clinical remission.	Week 20
Percentage of Participants With Change in DAS28-ESR of Greater Than or Equal (>=) 1.2 After First Course of Treatment	DAS28 was calculated from SJC and TJC using an assessment of 28 joints, the erythrocyte sedimentation rate (ESR) (milliliter per hour [ml/hr]), and Patient's Global Assessment (PGH) of disease activity (measured on a 0 to 100 mm Visual Analogue Scale [VAS] where 0=no disease activity and 100=worst disease activity). DAS28 was calculated using the following formula: DAS28 = 0.56*square root (sqrt) (TJC28) + 0.28*sqrt(SJC28) + 0.70*natural logarithm (ln) (ESR) + 0.014*PGH of disease activity. Total score range: 0-10, with a higher score indicated more disease activity. DAS28 <=3.2 implied low disease activity, DAS >3.2 to 5.1 implied moderate disease activity and DAS >5.1 implied high disease activity, and DAS28 <2.6 = clinical remission.	Week 20
Percentage of Participants With EULAR Response	The DAS28 score is a measure of the participant's disease activity. It is based on the tender joint count (28 joints), swollen joint count (28 joints), patient's global assessment of disease activity [visual analog scale: 0=no disease activity to 100=maximum disease activity], and ESR. DAS28 total scores range from 0 to 10. DAS28 <=3.2 indicates low disease activity, DAS28 >3.2 to 5.1 indicates moderate to high disease activity. A negative CFB indicates improvement. The DAS28-based EULAR response criteria were used to measure individual response as none, good, and moderate, depending on the extent of CFB and the level of disease activity reached. Good response: DAS28 <=3.2 and a CFB >1.2. Moderate response: DAS28 <=3.2 and CFB >0.6 to <=1.2, DAS28 >3.2 to <=5.1 and CFB >1.2 or >0.6 to <=1.2, DAS28 >5.1 and CFB >1.2. No response: DAS28 <=3.2 and CFB >=0.6, DAS28 >3.2 to <=5.1 and CFB <=0.6, DAS28 >5.1 and CFB >0.6 to <=1.2 or <=0.6.	Week 20
Percentage of Participants With EULAR Response in Subgroup of Participants Who Had Been Treated With Anti-TNF Previously	The DAS28 score is a measure of the participant's disease activity. It is based on the tender joint count (28 joints), swollen joint count (28 joints), patient's global assessment of disease activity [visual analog scale: 0=no disease activity to 100=maximum disease activity], and ESR. DAS28 total scores range from 0 to 10. DAS28 <=3.2 indicates low disease activity, DAS28 >3.2 to 5.1 indicates moderate to high disease activity. A negative CFB indicates improvement. The DAS28-based EULAR response criteria were used to measure individual response as none, good, and moderate, depending on the extent of CFB and the level of disease activity reached. Good response: DAS28 <=3.2 and a CFB >1.2. Moderate response: DAS28 <=3.2 and CFB >0.6 to <=1.2, DAS28 >3.2 to <=5.1 and CFB >1.2 or >0.6 to <=1.2, DAS28 >5.1 and CFB >1.2. No response: DAS28 <=3.2 and CFB >=0.6, DAS28 >3.2 to <=5.1 and CFB <=0.6, DAS28 >5.1 and CFB >0.6 to <=1.2 or <=0.6.	Week 20
Percentage of Participants With Remission (DAS28 <2.6) and Low Disease Activity Following Each Treatment Course	DAS28 was calculated from SJC and TJC using an assessment of 28 joints, the erythrocyte sedimentation rate (ESR) (milliliter per hour [ml/hr]), and Patient's Global Assessment (PGH) of disease activity (measured on a 0 to 100 mm Visual Analogue Scale [VAS] where 0=no disease activity and 100=worst disease activity). DAS28 was calculated using the following formula: DAS28 = 0.56*square root (sqrt) (TJC28) + 0.28*sqrt(SJC28) + 0.70*natural logarithm (ln) (ESR) + 0.014*PGH of disease activity. Total score range: 0-10, with a higher score indicated more disease activity. DAS28 <=3.2 implied low disease activity, DAS >3.2 to 5.1 implied moderate disease activity and DAS >5.1 implied high disease activity, and DAS28 <2.6 = clinical remission.	Week 20
Number of Participants With Remission (DAS28 <2.6) and Low Disease Activity Following Each Treatment Course for Subgroup of Participants Who Had Been Treated With Etanercept or Adalimumab or Infliximab Before Rituximab	The DAS28 score is a measure of the participant's disease activity. It is based on the tender joint count (28 joints), swollen joint count (28 joints), patient's global assessment of disease activity [visual analog scale: 0=no disease activity to 100=maximum disease activity], and ESR. DAS28 total scores range from 0 to 10. DAS28 <=3.2 indicates low disease activity, DAS28 >3.2 to 5.1 indicates moderate to high disease activity. A negative change from Baseline (CFB) indicates improvement.

Up to 39 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Health Assessment Questionnaire (HAQ) Score at Week 20	HAQ is a self-completed patient questionnaire specific for rheumatoid arthritis (RA). It consists of 20 questions referring to 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip; common daily activities. Each domain has at least 2 component questions. There are 4 possible responses for each component 0=without any difficulty 1=with some difficulty 2=with much difficulty 3=unable to do. Calculate HAQ the patient must have a domain score for at least 6 of 8 domains. The HAQ is the sum of the scores, divided by the number of domains that have a score (in range 6-8) for a total possible score minimum/maximum 0 (best) to 3 (worst). A negative change from baseline indicated improvement.	Baseline and Week 20
