Number of Participants in DAS 28 C-reactive Protein (CRP) Remission at Month 12
Number of participants who achieved remission at Month 12 of treatment, as defined by a Disease Activity Score (DAS) 28-CRP score of <2.6. DAS 28-CRP is a continuous measure, a composite of 4 variables: number of tender joints out of 28 joints, number of swollen joints out of 28 joints, CRP (in mg/L), and subject assessment of disease activity measure on a Visual Analogue Scale (VAS) of 100 millimeters (mm). The DAS28 scale=0 (best) to 10 (worst), indicating the current activity of the rheumatoid arthritis. A DAS28 >5.1 = high disease activity; <=3.2 = low disease activity; <2.6 = remission.
Mean Change From Baseline in Radiographic Total Score to Month 12
To assess joint damage progression, the Genant-modified Sharp scoring method was used to evaluate radiographs of hands/wrists and feet for erosions and joint space narrowing (JSN). The total Genant-modified Sharp score ranges from 0 (no radiographic damage) to 290 (worst possible radiographic damage) and is the sum of the erosion score (range 0-145) and the joint space narrowing score (range 0-145). Higher scores indicated more damage.

Secondary Outcome Measures

Number of Participants With American College of Rheumatology (ACR) 50 Response at Month 12
ACR 50 response was defined as a 50% improvement from baseline to Month 12 in tender and swollen joint counts and 50% improvement in 3 of the remaining 5 core set measures (subject global assessment of pain, subject global assessment of disease activity, physician global assessment of disease activity, subject assessment of physical function), and 1 acute phase reactant value [ie, CRP].
Number of Participants With Major Clinical Response (MCR) at Month 12
MCR was defined as 6 months of consecutive ACR 70 response at Month 12. ACR 70, the American College of Rheumatology (ACR) definition of 70% improvement was based on a 70% improvement (compared to baseline values) in tender and swollen joint counts and 70% improvement in 3 of the remaining 5 core set measures (subject global assessment of pain, subject global assessment of disease activity, physician global assessment of disease activity, subject assessment of physical function, and 1 acute phase reactant value [ie, CRP]).
Adjusted Mean Change From Baseline in DAS-28-CRP Score to Month 12
DAS 28-CRP is a continuous variable that is a composite of 4 variables: the number of tender joints out of 28 joints, the number of swollen joints out of 28 joints, CRP in milligrams/Liter (mg/L), and subject assessment of disease activity measure on a Visual Analogue Scale (VAS) of 100 millimeters (mm). The DAS28 scale=0 to 10, indicating the current activity of the rheumatoid arthritis. A DAS28 >5.1=high disease activity; <3.2=low disease activity; <2.6=remission. Change from Baseline=Post-baseline - Baseline value; Adjusted for baseline value.
Number of Participants With Health Assessment Questionnaire (HAQ) Response at Month 12
Physical function was evaluated using the HAQ-disability index (HAQ-DI), a questionnaire with 20 questions assessing function in 8 domains: dressing, arising, eating, walking, hygiene, reach, grip, and common activities. The questions are evaluated on a 4-point scale: 0 = without any difficulty; 1 = with some difficulty; 2 = with much difficulty; 3 = unable to do. The 8 category scores are averaged into an overall HAQ-DI score on a scale from 0 (no disability) to 3 (completely disabled). Higher scores indicate greater dysfunction. HAQ response=improvement of at least 0.3 units from baseline.
Adjusted Mean Change in Short Form 36 (SF-36) From Baseline to Month 12
The SF-36 covers 8 health dimensions: 4 physical subscales (physical function, role-physical, bodily pain, and general health) and 4 mental subscales (vitality, social function, role-emotional, and mental health). The scores range from 0 to 100, with a higher score indicating better quality of life. Two summary scores (physical and mental component summaries) were produced taking a weighted linear combination of the 8 individual subscales. Change from Baseline=Post-baseline - Baseline value; adjusted for baseline value.
Mean Change From Baseline in Radiographic Erosion and Joint Space Narrowing (JSN) Scores to Month 12
To assess joint damage progression, the Genant-modified Sharp scoring method was used to evaluate radiographs of hands/wrists and feet for erosions and JSN. The erosion score range is 0 (no radiographic damage) to 145 (worst possible radiographic damage). The joint space narrowing score range is 0 (no radiographic damage) to 145 (worst possible radiographic damage). Higher scores indicated more damage. Change from baseline = Post-baseline - Baseline value
Number of Participants With Anti-abatacept or Anti-CTLA4-T Responses in the Double-blind Period as Analyzed by Enzyme-linked-immunosorbent Serologic Assay (ELISA)
Serum samples were analyzed by ELISA to detect antibodies against the whole molecule (both CTLA4 and Ig [anti-abatacept antibody]) or solely to CTLA4 (anti-CTLA4-T antibody). Reported as titer, the reciprocal of the sample dilution which yielded a signal equivalent to the statistically set cut point for the assay. For the anti-abatacept assay, minimum required dilution is 400-fold, therefore seronegative samples are those < lowest reportable titer (<400). For the anti-CTLA4-T assay, minimum required dilution is 25-fold, therefore seronegative samples are those < lowest reportable titer (<25).
Number of Participants With Anti-abatacept or Anti-CTLA4-T Responses During the Open-Label Period (From Month 12 to Month 24) as Analyzed by ELISA

Reported as titer, the reciprocal of the sample dilution which yielded a signal equivalent to the statistically set cut point for the assay. For the anti-abatacept assay, minimum required dilution is 400-fold, therefore seronegative samples are those < lowest reportable titer (<400). For the anti-CTLA4-T assay, minimum required dilution is 25-fold, therefore seronegative samples are those < lowest reportable titer (<25).
Number of Participants With Health Assessment Questionnaire (HAQ) Response at Month 24
Physical function was evaluated using the HAQ-disability index (HAQ-DI), a questionnaire with 20 questions assessing function in 8 domains: dressing, arising, eating, walking, hygiene, reach, grip, and common activities. The questions are evaluated on a 4-point scale: 0 = without any difficulty; 1 = with some difficulty; 2 = with much difficulty; 3 = unable to do. The 8 category scores are averaged into an overall HAQ-DI score on a scale from 0 (no disability) to 3 (completely disabled). Higher scores indicate greater dysfunction. HAQ response=improvement of at least 0.3 units from baseline.
Mean Change From Baseline in Radiographic Total, Erosion and JSN Scores to Month 24
To assess joint damage progression, the Genant-modified Sharp scoring method was used to evaluate radiographs of hands/wrists and feet for erosions and JSN. The total Genant-modified Sharp score ranges from 0 (no radiographic damage) to 290 (worst possible radiographic damage) and is the sum of the erosion score (range 0-145) and the joint space narrowing score (range 0-145). Higher scores indicated more damage. Change from baseline = Postbaseline - baseline value.
Number of Participants Without Radiographic Progression (as Measured by in Erosion Scores, JSN Scores, and Total Scores) From Baseline at Month 24
Participants with no radiographic progression (defined as change in score <=0 or <=0.5), from baseline to Month 24. To assess joint damage progression, the Genant-modified Sharp scoring method was used to evaluate radiographs of hands/wrists and feet for erosions and JSN. The total Genant-modified Sharp score ranges from 0 (no radiographic damage) to 290 (worst possible radiographic damage) and is the sum of the erosion score (range 0-145) and the joint space narrowing score (range 0-145). Higher scores indicated more damage.

The joint space narrowing score range is 0 (no radiographic damage) to 145 (worst possible radiographic damage). Higher scores indicated more damage. Change from baseline = Post-baseline - Baseline value
Time Frame
Baseline, Month 12
Title
Number of Participants With Anti-abatacept or Anti-CTLA4-T Responses in the Double-blind Period as Analyzed by Enzyme-linked-immunosorbent Serologic Assay (ELISA)
Description
Serum samples were analyzed by ELISA to detect antibodies against the whole molecule (both CTLA4 and Ig [anti-abatacept antibody]) or solely to CTLA4 (anti-CTLA4-T antibody). Reported as titer, the reciprocal of the sample dilution which yielded a signal equivalent to the statistically set cut point for the assay. For the anti-abatacept assay, minimum required dilution is 400-fold, therefore seronegative samples are those < lowest reportable titer (<400). For the anti-CTLA4-T assay, minimum required dilution is 25-fold, therefore seronegative samples are those < lowest reportable titer (<25).
Time Frame
includes data up to approximately 85 days past the last dose of the double-blind period or start of the open-label period, whichever occurred first.
Title
Number of Participants With Anti-abatacept or Anti-CTLA4-T Responses During the Open-Label Period (From Month 12 to Month 24) as Analyzed by ELISA
Description
Serum samples were analyzed by ELISA to detect antibodies against the whole molecule (both CTLA4 and Ig [anti-abatacept antibody]) or solely to CTLA4 (anti-CTLA4-T antibody). Reported as titer, the reciprocal of the sample dilution which yielded a signal equivalent to the statistically set cut point for the assay. For the anti-abatacept assay, minimum required dilution is 400-fold, therefore seronegative samples are those < lowest reportable titer (<400). For the anti-CTLA4-T assay, minimum required dilution is 25-fold, therefore seronegative samples are those < lowest reportable titer (<25).
Time Frame
Includes open-label data up to approximately 85 days post last dose in the open-label period or start of the maintenance sub-study, whichever occurred first.
Title
Number of Participants With Health Assessment Questionnaire (HAQ) Response at Month 24
Description
Physical function was evaluated using the HAQ-disability index (HAQ-DI), a questionnaire with 20 questions assessing function in 8 domains: dressing, arising, eating, walking, hygiene, reach, grip, and common activities. The questions are evaluated on a 4-point scale: 0 = without any difficulty; 1 = with some difficulty; 2 = with much difficulty; 3 = unable to do. The 8 category scores are averaged into an overall HAQ-DI score on a scale from 0 (no disability) to 3 (completely disabled). Higher scores indicate greater dysfunction. HAQ response=improvement of at least 0.3 units from baseline.
Time Frame
Baseline, Month 24
Title
Mean Change From Baseline in Radiographic Total, Erosion and JSN Scores to Month 24
Description
To assess joint damage progression, the Genant-modified Sharp scoring method was used to evaluate radiographs of hands/wrists and feet for erosions and JSN. The total Genant-modified Sharp score ranges from 0 (no radiographic damage) to 290 (worst possible radiographic damage) and is the sum of the erosion score (range 0-145) and the joint space narrowing score (range 0-145). Higher scores indicated more damage. Change from baseline = Postbaseline - baseline value.
Time Frame
Baseline, Month 24
Title
Number of Participants Without Radiographic Progression (as Measured by in Erosion Scores, JSN Scores, and Total Scores) From Baseline at Month 24
Description
Participants with no radiographic progression (defined as change in score <=0 or <=0.5), from baseline to Month 24. To assess joint damage progression, the Genant-modified Sharp scoring method was used to evaluate radiographs of hands/wrists and feet for erosions and JSN. The total Genant-modified Sharp score ranges from 0 (no radiographic damage) to 290 (worst possible radiographic damage) and is the sum of the erosion score (range 0-145) and the joint space narrowing score (range 0-145). Higher scores indicated more damage.
Time Frame

Title
Number of Participants Without Radiographic Progression (as Measured by in Erosion Scores, JSN Scores, and Total Scores) at Month 24 in Participants Without Progression at Month 12
Description
Participants with no radiographic progression ((defined as change in score <=0 or <=0.5), sustained from Month 12 and Month 24. To assess joint damage progression, the Genant-modified Sharp scoring method was used to evaluate radiographs of hands/wrists and feet for erosions and JSN. The total Genant-modified Sharp score ranges from 0 (no radiographic damage) to 290 (worst possible radiographic damage) and is the sum of the erosion score (range 0-145) and the joint space narrowing score (range 0-145). Higher scores indicated more damage.

Title
Number of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), Deaths, and Discontinuations Reported During the Double-blind Period
Description
AE=any new untoward medical occurrence or worsening of a pre-existing medical condition in a subject administered an investigational product and that does not necessarily have a causal relationship with this treatment. Related AE/SAE=Certain, Probable, Possible, or Missing. SAE=any untoward medical occurrence that results in death, is life-threatening, requires or prolongs inpatient hospitalization (including elective surgery), results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is an important medical event.
Time Frame
Includes data up to 56 days post the last dose in the double-blind period or start of the open-label period, whichever occurred first.
Title
Number of Participants With Laboratory Values Meeting the Marked Abnormality Criteria During the Double-blind Period
Description
Number of participants with laboratory values (hematology, liver and kidney functions, electrolytes, glucose tests, protein tests, metabolite tests, and urine chemistry tests) considered markedly abnormal according to prespecified protocol criteria
Time Frame
Includes data up to 56 days post the last dose in the double-blind period or start of the open-label period, whichever occurred first.
