Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mean Trough Serum Concentration (Cmin) of Abatacept	Cmin of abatacept was determined from serum samples.	Days 29, 85, 57, and 85
Percentage of Participants With A Positive Anti-abatacept Response (Based on Enzyme-linked Immunosorbent Assay [ELISA]) at Day 85	Using the ELISA, any positive (titer of 400 or greater) postbaseline sample was classified as positive immunogenicity. The percentage of participants with at least 1 positive antibody response (anti-abatacept and/or anti-CTLA4-T) during the 85 days was tabulated by antibody specificity and overall.	Day 1 (Baseline) through Day 85
Percentage of Participants With A Positive Anti-abatacept Response (Based on Electrochemiluminescence [ECL] Immunoassay) at Day 85	Number of participants was tabulated using ECL assay with at least 1 positive abatacept-induced immunogenic response (CTLA4 and possibly Ig, Ig and/or Junction Region) in the first 85 days. Positive response (titers >10) included: A missing baseline immunogenicity measurement and a positive immunogenicity response postbaseline; A negative baseline immunogenicity response and a positive immunogenicity response postbaseline; A positive baseline immunogenicity response and a positive immunogenicity response postbaseline that has a titer value strictly greater than the baseline titer value	Day 1 (Baseline) through Day 85
Mean Disease Activity Score 28 Based on C-reactive Protein (DAS 28-CRP) Scores Over Time	The DAS 28-CRP is a measure of disease activity in rheumatoid arthritis (RA) and assesses the 28 joints RA commonly affects; the score includes the number of tender and swollen joints (out of 28), C-reactive protein level (a measure of inflammation in the blood), and the patient's global assessment of health (ranging from very good to very bad). DAS-CRP scores range from 0 to 10, with higher values indicating greater disease activity. Individual measures are fed into a complex mathematical formula to produce the overall DAS (a score greater than 5.1 implies active disease; less than 3.2, well controlled disease; and less than 2.6, remission.)	Day 1 (Baseline) through Day 1093
Percentage of Participants With Low Disease Activity Score (LDAS) and Disease Activity Score 28 Based on C-reactive Protein (DAS 28-CRP) Remission Over Time:	LDAS is defined as DAS 28-CRP ≤3.2. DAS 28-CRP remission is defined as DAS 28-CRP <2.6. The DAS 28-CRP is a measure of disease activity in rheumatoid arthritis (RA) and assesses the 28 joints RA commonly affects; the score includes the number of tender and swollen joints (out of 28), C-reactive protein level (a measure of inflammation in the blood), and the patient's global assessment of health (ranging from very good to very bad). DAS-CRP scores range from 0 to 10, with higher values indicating greater disease activity. Individual measures are fed into a complex mathematical formula to produce the overall DAS (a score greater than 5.1 implies active disease; less than 3.2, well controlled disease; and less than 2.6, remission.)	Day 1 (Baseline) through Day 1093
Mean Health Assessment Questionnaire-Disability Index (HAQ-DI) Scores Over Time	The HAQ-DI assesses patients' functional ability by rating their abilities over the previous week. At least 2 questions are asked from each of 8 categories: dressing and grooming, hygiene, arising, reach, eating, grip, walking, and common daily activities. Patients rate difficulty performing specific tasks: 0=without difficulty, 1=with some difficulty, 2=with much difficulty, and 3=unable to do. The sum of the categories is divided by the number of categories answered, yielding a score from 0-3.	Day 1 (Baseline) to Day 1093
