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.

Secondary outcomes (3)
Minimum Observed Serum Concentration (Cmin) of Abatacept Over Time in the ACP Device Substudy
Trough levels of abatacept were evaluated based upon serum samples. Day 1 pharmacokinetics were based on exposure to the pre-filled syringes and did not reflect abatacept exposure via the ACP device.
Measured: Days 1, 29, 57, 85, 169, and 253 of ACP substudy
Number of Participants With Positive Anti-abatacept or Anti-Cytotoxic T Lymphocyte Antigen 4-T Cell (CTLA4-T) Responses Over Time by Enzyme Linked Immunosorbant Assay (ELISA) in the ACP Device Substudy
Serum samples from all treated adult participants with active rheumatoid arthritis were screened for the presence of drug-specific antibodies using ELISA. Immunogenicity was defined as the presence of a positive anti-abatacept or anti-CTLA4 antibody.
Measured: ACP substudy Day 1 to last substudy assessment occurring prior to 1st dose of non-ACP SC abatacept (administered once participants switched back to main study). For participants discontinuing both studies: Day 1 of ACP dosing to 28 days post last ACP dose
Number of Participants With Positive Anti-abatacept Responses Over Time by Electrochemiluminescence Immunoassay in the ACP Device Substudy
An electrochemiluminescence immunoassay screened sera for drug-specific antibodies; immunocompetition was used to identify specific anti-Abatacept reactivity. CTLA4 and Possibly immunoglobulin (Ig) category=reactivity against extracellular domain of human CTLA4, constant regions of human IgG1, or both (CTLA4Ig; Abatacept molecule). Ig and/or Junction (JNCT)category=reactivity against constant regions and/or hinge region of human IgG1. Drug-induced seropositivity defined as a post-baseline titer higher than Baseline, or any post-baseline positivity if Baseline value was missing. TRT=treatment
Measured: ACP substudy Day 1 to last substudy assessment occurring prior to 1st dose of non-ACP SC abatacept (administered once participants switched back to main study). For participants discontinuing both studies: Day 1 of ACP dosing to 85 days post last ACP dose

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Abatacept combination product (ACP) in people with Rheumatoid Arthritis (RA), run by Bristol-Myers Squibb.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Jan 2012. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 6 Jul 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
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 (time frame: ACP substudy Day 1 to last substudy assessment occurring prior to the 1st dose of non-ACP subcutaneous (SC) abatacept, assessed up to 12 months). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jan 2012.
