Experimental
Arm Label
Abatacept Combination Product (ACP)
Arm Description
Participants from the long-term period of study NCT00559585 who enrolled in the ACP substudy switched to administration of subcutaneous (SC) abatacept via the ACP for the duration of the substudy. Abatacept was administered SC using the ACP by the participant or caregiver on Substudy Day 1 and at weekly intervals thereafter. The ACP was a pre-filled liquid product device delivering 125 mg abatacept/device (125 mg/mL).
Outcomes
Primary Outcome Measures
Number of Participants With Death, Serious Adverse Events (SAEs), Treatment-related SAEs, SAEs Leading to Discontinuation, Adverse Events (AEs), Treatment-related AEs, and AEs Leading to Discontinuation
An AE is any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that does not necessarily have a causal relationship with treatment. An SAE is any unfavorable medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency or abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization. Treatment-related=possibly, probably, or certainly related to and of unknown relationship to study treatment.
Number of Participants With AEs of Special Interest in the ACP Device Substudy
AE=any new untoward medical occurrence or worsening of a preexisting medical condition which does not necessarily have a causal relationship with this treatment. AEs of special interest are those AEs that may be associated with the use of immunomodulatory drugs including all infections, local injection reactions (prespecified), and systemic injection reactions (within 24 hours of dosing).

Ig and/or Junction (JNCT)category=reactivity against constant regions and/or hinge region of human IgG1.
