Measure Description |
Time Frame |
---|---|---|
Number of Participants in DAS 28 C-reactive Protein (CRP) Remission at Month 12
Time Frame: 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.

Month 12
|
Mean Change From Baseline in Radiographic Total Score to Month 12
Time Frame: Baseline, 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.

|
Adjusted Mean Change From Baseline in DAS-28-CRP Score to Month 12
Time Frame: Baseline, 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.
|
Baseline, Month 12
|
Number of Participants With Health Assessment Questionnaire (HAQ) Response at Month 12
Time Frame: 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.
|
Month 12
|
Adjusted Mean Change in Short Form 36 (SF-36) From Baseline to Month 12
Time Frame: Baseline, 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.
|
Baseline, Month 12
|
Mean Change From Baseline in Radiographic Erosion and Joint Space Narrowing (JSN) Scores to Month 12
Time Frame: Baseline, 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
|
Baseline, Month 12
|
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)
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.
|
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).
|

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.

Number of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), Deaths, and Discontinuations Reported During the Double-blind Period
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.
|
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.
|
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.
|
Number of Participants With Laboratory Values Meeting the Marked Abnormality Criteria During the Double-blind Period
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.
|
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
|
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.
