About this study
The purpose of this clinical research study is to learn if abatacept is safe when co-administered with other approved rheumatoid arthritis medications.
Read the detailed description
This was a multinational, multicenter, randomized, double-blind, 2-arm, parallel-dosing designed study. The treatment period was 12 months. Eligible participants were randomized to 1 of 2 treatment groups: abatacept fixed dose approximating 10 mg/kg (based on participant's body weight; 500 mg for participants weighing < 60kg; 750 mg for participants weighing 60 to 100 kg; and 1 gram for participants weighing > 100 kg, monthly) or placebo intravenous (IV) infusion. All participants continued their background therapy(ies) for rheumatoid arthritis (RA) (non-biologic or biologic disease-modifying drugs [DMARDs], or combination) throughout the double-blind treatment period. Double-blind study medication (abatacept or placebo) was administered on Days 1, 15, 29, and every 28 days thereafter, for a total of 14 doses.
All participants who completed the 12-month double-blind study period (Day 1 through Day 365), were eligible to continue into the open-label period. All eligible participants (active or placebo) were re-allocated to receive abatacept at a weight-tiered dose that approximated 10 mg/kg, based on their Day 365 body weight. Participants continued to receive infusions every 28 days.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this clinical research study is to learn if abatacept is safe when co-administered with other approved rheumatoid arthritis medications.
Detailed description
This was a multinational, multicenter, randomized, double-blind, 2-arm, parallel-dosing designed study. The treatment period was 12 months. Eligible participants were randomized to 1 of 2 treatment groups: abatacept fixed dose approximating 10 mg/kg (based on participant's body weight; 500 mg for participants weighing < 60kg; 750 mg for participants weighing 60 to 100 kg; and 1 gram for participants weighing > 100 kg, monthly) or placebo intravenous (IV) infusion. All participants continued their background therapy(ies) for rheumatoid arthritis (RA) (non-biologic or biologic disease-modifying drugs [DMARDs], or combination) throughout the double-blind treatment period. Double-blind study medication (abatacept or placebo) was administered on Days 1, 15, 29, and every 28 days thereafter, for a total of 14 doses.
All participants who completed the 12-month double-blind study period (Day 1 through Day 365), were eligible to continue into the open-label period. All eligible participants (active or placebo) were re-allocated to receive abatacept at a weight-tiered dose that approximated 10 mg/kg, based on their Day 365 body weight. Participants continued to receive infusions every 28 days.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Double-blind Abatacept and Open-label Abatacept in people with Rheumatoid Arthritis, run by Bristol-Myers Squibb at 44 sites in United States.
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 2 inclusion and 2 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 24 Nov 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 44 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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 3 May 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?
Double Blind Period (DB); Number of Participants With Death, Serious Adverse Events (SAEs), Related SAEs, SAEs Leading to Discontinuation, Adverse Events (AEs), Related AEs, or AEs Leading to Discontinuation (time frame: Day 1 to Day 365, and including data up to 56 days post last dose of double-blind medication). The study lists 12 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00048932, which also lists 1 linked publication.
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 24 Nov 2011.
