  • Short Term Period: Steady-state Trough Serum Concentration (Cmin) of Abatacept Following Weekly Subcutaneous Dosing in Participants With Active Rheumatoid Arthritis Receiving Disease Modifying Anti-rheumatic Drugs (DMARDS) [ Time Frame: Days 71 to 85 ] [ Designated as safety issue: No ]
    Participants received abatacept while also receiving DMARDS over a short term (ST) 12 Week period. To eliminate contribution from the IV loading dose of abatacept during the short term study period, Cmin values were selected from Days 71 to 85, when contribution from IV was negligible. Minimum trough serum concentration of abatacept (Cmin) was measured in micrograms/milliliter (µg/mL). Data are presented by treatment the participant actually received, not by what they were randomized to receive.
  • Number of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), Deaths, Discontinuations Due to Adverse Events Reported During the Variable Dosing Phase of the Long Term Period (LTE) [ Time Frame: Day 85 to 56 days post last dose ] [ Designated as safety issue: Yes ]
    AEs during variable dose phase of LTE + 56 days post last dose in the variable dose phase or start of the fixed dose phase, which ever came first; includes deaths reported during the variable dose phase including those that occurred greater than 56 days after last dose. Medical Dictionary for Regulatory Activities (MedDRA) version: 15.1. AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. SAE=medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization (included hospitalizations for elective surgical procedures). Treatment-related=having certain, probable, possible, or missing relationship to study drug. Data presented by treatment the participant was randomized to and not what they actually received.
  • Number of Participants With Pre-specified AEs of Special Interest in the Variable Dosing Phase of Long Term Extension (LTE) [ Time Frame: Day 85 to Day 533 ] [ Designated as safety issue: Yes ]
    LTE period with variable abatacept dosing starting on Day 85 and continuing until Day 533 when LTE fixed dosing started. AEs of special interest: infection and/or infestation; neoplasms (malignant); pre-specified autoimmune disorder; infusional AEs (peri-infusional: pre-specified AEs occurring during first 24 hours (hrs) after start of the IV loading dose; acute infusional: pre-specified AEs occurring during the first hour after the start of the IV loading dose; systemic injection site reactions (SIR): pre-specified AEs for SIR; local injection site reaction: pre-specified AEs for local site reaction. Data are presented by treatment the participant was randomized to and not what they actually received.
  • Number of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), Deaths, Discontinuations Due to Adverse Events Summarized Over the Entire Long Term Extension (LTE) Period (Both Variable and Fixed Dosing) [ Time Frame: Day 533 to 56 Days Post last dose ] [ Designated as safety issue: Yes ]
    On Day 85 participants rolled over into the LTE with variable dose phase first and at Day 533, a fixed dose phase of 125 mg abatacept SC weekly, irrespective of body weight. This summary includes AEs reported during entire LTE treatment plus 56 days post last dose; includes all deaths reported during the LTE including those that occurred greater than 56 days after last dose. MedDRA version: 15.1. AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. SAE=a medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization (also included hospitalizations for elective surgical procedures). Treatment-related=having certain, probable, possible, or missing relationship to study drug.
This study will measure the pharmacokinetics of abatacept administered subcutaneously. PK samples are collected before and at the end of the IV dose, just prior to each SC dose, and on 4 days between doses

Overall LTE includes both the variable and fixed abatacept dosing periods and was from the end of the ST period (Day 85) up to 168 days post last dose (treatment in LTE ranged from 4.4 to 74.2 months. Data in the ST period are summarized by the treatment the participants actually received, while the LT period data are summarized by treatment the participant was randomized to receive.
Samples for anti-CTLA4Ig and anti-CTLA4 are collected every 2 weeks and at follow-up visits. Rheumatoid Factor is colleted on regular intervals and at Study Discharge.
