Secondary	Retreated Subjects With American College of Rheumatology 50% (ACR50) Response and American College of Rheumatology 70% (ACR70) Response at Week 48 Relative to Baseline	ACR50 or ACR70 response was defined as a = 50% or 70% improvement compared with baseline in both tender joint count (TJC) [68 joints] and swollen joint count (SJC) [66 joints] as well as a = 50% or 70% improvement in three of five additional measurements: 1) Physician's Global Assessment of disease activity [visual analog scale: 0=no disease activity to 100=maximum disease activity]; 2) Patient's Global Assessment of Disease Activity [visual analog scale: 0=no disease activity to 100=maximum disease activity]; 3) Patient's Assessment of Pain [visual analog scale: 0=no pain to 100=unbearable pain]; 4) Health Assessment Questionnaire [20 questions, 8 components: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and activities, 0=without difficulty to 3=unable to do] and 5) erythrocyte sedimentation rate.	Baseline, Week 48	No
Secondary	Change From Baseline in the Disease Activity Score Using 28 Joint Counts (DAS28-ESR) at Week 48	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 2 to 10. Higher values indicate higher disease activity. A negative change from baseline indicates improvement.	48 weeks	No
Secondary	Change From Baseline in Disease Activity Score (DAS28-CRP) at Week 48	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 C-Reactive Protein (CRP) for a total possible score of 2 to 10.

Secondary	Percentage of Retreated Subjects With a European League Against Rheumatism (EULAR) Response at Week 48	Change of the Disease Activity Score 28 score from baseline was used to determine EULAR responses of good, moderate, or no response. For a post-baseline score = 3.2, a change from baseline of < -1.2 was a good response, < -0.6 to = -1.2 was a moderate response, and = -0.6 was no response. For a post-baseline score > 3.2 to = 5.1, a change from baseline of < -0.6 was a moderate response and = -0.6 was no response.

It consists of 20 questions referring to 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip,and common daily activities. Each domain has at least two component questions. There are four possible responses for each component ranging from 0(without any difficulty) to 4 (unable to do).HAQ-DI=sum of worst scores in each domain divided by the number of domains answered. A negative change from baseline indicates improvement.	Baseline, Week 48	No
Secondary	Change From Baseline in American College of Rheumatology (ACR) Core Set Component: Subject's Global Assessment of Disease Activity at Week 48	Participants rated their disease activity at baseline and Week 48 using the Visual Analog Scale (VAS) on a scale of 0 (best) to 100 (worse). A negative change from baseline indicates improvement.	Baseline, Week 48	No
Secondary	Change From Baseline in American College of Rheumatology (ACR) Core Set Component: Physician's Global Assessment of Disease Activity at Week 48	A Rheumatologist or a skilled Arthritis assessor rated the patient's disease activity at baseline and Week 48 using the Visual Analog Scale (VAS) on a scale of 0 (best) to 100 (worse). A negative change from baseline indicates improvement.	Baseline, Week 48	No
Secondary	Change From Baseline in American College of Rheumatology (ACR) Core Set Component: Subject's Assessment of Pain at Week 48	Patients rated their pain at baseline and Week 48 using the Visual Analog Scale (VAS) on a scale of 0 (none) to 100 (unbearable pain). A negative change from baseline indicates improvement.	Baseline, Week 48	No
Secondary	Change From Baseline in American College of Rheumatology (ACR) Core Set Component: C-Reactive Protein at Week 48	Blood was collected for C-Reactive Protein, an inflammatory marker, at Baseline and Week 48. A negative change from baseline indicates improvement.	Baseline, Week 48	No

A negative change from baseline indicates improvement.	Baseline, Week 48	No
Secondary	Percentage of Retreated Subjects With a Change = 0.22 From Baseline in HAQ-DI at Week 48	The Stanford Health Assessment Questionnaire disability index (HAQ-DI) is a patient completed questionnaire specific for rheumatoid arthritis. It consists of 20 questions referring to 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip and common daily activities. Each domain has at least two component questions. There are four possible responses for each component ranging from 0(without any difficulty) to 4 (unable to do). HAQ-DI=sum of worst scores in each domain divided by the number of domains answered.	Baseline, Week 48	No
Secondary	Percentage of Retreated Subjects With a Change = 0.3 From Baseline in HAQ-DI at Week 48	The Stanford Health Assessment Questionnaire disability index (HAQ-DI) is a patient completed questionnaire specific for rheumatoid arthritis. It consists of 20 questions referring to 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip and common daily activities. Each domain has at least two component questions. There are four possible responses for each component ranging from 0(without any difficulty) to 4 (unable to do).HAQ-DI=sum of worst scores in each domain divided by the number of domains answered.	Baseline, Week 48	No
Secondary	ACRn in Retreated Subjects at Week 48	The ACRn is calculated for each participant by taking the lowest percentage improvement in (1) swollen joint count or (2) tender joint count or (3) the median of the remaining 5 components of the ACR response (participant's assessment of disease activity; participant's global assessment of pain; physician's assessment of disease activity; participant's assessment of physical function; an acute phase reactant value - CRP). A positive ACRn Score indicates an improvement.	Baseline, Week 48	No
Secondary	Change From Baseline in SF-36 Health Summary Scores at Week 48 in Retreated Subjects	The SF-36 is a questionnaire used to assess physical functioning and is made up of eight domains: Physical Functioning, Role Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role-Emotional and Mental Health. Transforming and standardizing these domains leads to the calculation of the Physical (PCS) and Mental (MCS) Component Summary measures. Scores ranging from 0 to 100, with 0=worst score (or quality of life) and 100=best score. A positive change from baseline indicates improvement.	Baseline, Week 48	No
Secondary	Change From Baseline in Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-F) at Week 48 in Retreated Subjects	FACIT-F is a 13-item questionnaire. Patients scored each item on a 5-point scale: 0 (Not at all) to 4 (Very much). The larger the patient's response to the questions (with the exception of 2 negatively stated), the greater the patient'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 patient'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). A higher score reflects an improvement in the patient's health status.	Baseline, Week 48	No
Secondary	Percentage of Retreated Subjects Achieving DAS28-ESR Remission at Week 48	DAS28-ESR remission was defined as a DAS28-ESR < 2.6	Week 48	No
Secondary	Percentage of Retreated Subjects Achieving DAS28-ESR Low Disease at Week 48	The DAS28-ESR score is a measure of the subject'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 (mm), and ESR. DAS28-ESR scores range from 0 - 10. Low disease activity is defined as achieving a DAS28-ESR score of less than or equal to 3.2.	Week 48	No
