Study Type Interventional
Study Design Allocation: Randomized;   Intervention Model: Parallel Assignment;   Masking: Double (Participant, Investigator);   Primary Purpose: Treatment
Condition Rheumatoid Arthritis (RA)
Interventions Drug: Subcutaneous (SC) Abatacept
Drug: Intravenous (IV) Abatacept
Enrollment 2492
Recruitment Details During the double blind short term (ST) period of the Main study, a sub-study in RA participants was initiated to evaluate anti-tumor necrosis factor (TNF) failure population. The sub-study was terminated early due to slow recruitment and participants from the sub-study were allowed to roll into the Main study during the LT Open Label Period.
Pre-assignment Details 2492 enrolled: 2472 in Main Study:1008 not randomized: 918 no longer met criteria, 61 withdrew consent, 7 lost to follow-up, 22 other reasons. Randomized, not treated: 4 no longer met criteria, 2 withdrew consent, and 1 randomization error; 20 enrolled in Anti-TNF sub-study; 2 not randomized as no longer met criteria; 18 randomized in substudy.
Arm/Group Title Subcutaneous (SC) Abatacept Intravenous (IV) Abatacept
Hide Arm/Group Description During the Main Study Double Blind ST Period, participants received 125 mg weekly SC abatacept injections for 6 months (with an IV abatacept loading dose on Day 1, based on weight). A double-dummy design was used to protect the blind, thus, participants also received IV injections of placebo (IV Placebo) with the exception that on Day 1 a loading dose of IV abatacept replaced the IV Placebo treatment. During the Open Label Long Term (LT) Period, participants in both the Main Study and the Anti-TNF Failure Sub-study switched to open-label SC abatacept. The study continued until SC formulation became commercially available on a country basis or the Sponsor terminated the study. During the Main study Double Blind ST Period, participants received IV abatacept infusions on Days 1, 15, 29, and every 28 days, thereafter for 6 months. A double-dummy design was used to protect the blind, thus, participants also received SC injections of placebo (SC Placebo). During the Open Label LT Period, participants in both the Main Study and the Anti-TNF Failure Sub-study switched to open-label SC abatacept. The study continued until SC formulation became commercially available on a country basis or the Sponsor terminated the study.

Arm/Group Title Subcutaneous (SC) Abatacept Intravenous (IV) Abatacept Total
Hide Arm/Group Description Participants received 125 mg weekly SC abatacept injections (with an intravenous [IV] abatacept loading dose on Day 1, based on weight). A double-dummy design was used to protect the blind, thus, participants also received IV injections of placebo (IV Placebo) with the exception that on Day 1 a loading dose of IV abatacept replaced the IV Placebo treatment. The Per Protocol (PP) Analysis Population (instead of the Intent-To-Treat Population) was used to perform primary and key secondary efficacy analyses as per regulatory guidelines for non-inferiority studies. Participants received IV abatacept infusions on Days 1, 15, 29, and every 28 days, thereafter. A double-dummy design was used to protect the blind, thus, participants also received SC injections of placebo (SC Placebo).

Participants were instructed to draw a vertical through a horizontal line to indicate state of rheumatoid arthritis. Distance from the "very well" end of the horizontal line to the vertical line drawn by the participant was the global disease assessment score on a scale of 1-10, where 1=controlled or equivocal rheumatoid arthritis activity, 1.1-4=mild activity, 4-8=moderate activity, and 8.1-10=high activity.

Measure Description: The DAS28 index measures disease activity in rheumatoid arthritis and is a composite derived from the number of swollen/tender joints, laboratory tests of inflammation (C-reactive protein measured in mg/L), and participant assessment of global health (by marking a 100 mm line from "very good" to "very bad"). A higher DAS28 score indicates worse control of disease. High disease activity is > 5.1, low disease activity is < 3.2 and remission is < 2.6.

SAE=any untoward medical occurrence that at any dose: results in death, is life-threatening, requires inpatient hospitalization or causes prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, results in development of drug dependency or drug abuse, is an important medical event.

Arm/Group Title Subcutaneous (SC) Abatacept Intravenous (IV) Abatacept
Hide Arm/Group Description:
During the Double Blind ST Period, participants received 125 mg weekly SC abatacept injections for 6 months (with an intravenous [IV] abatacept loading dose on Day 1, based on weight). A double-dummy design was used to protect the blind, thus, participants also received IV injections of placebo (IV Placebo) with the exception that on Day 1 a loading dose of IV abatacept replaced the IV Placebo treatment. An Anti-TNF Failure Sub-study was initiated using the same treatment as the Main study in order to assess the immunogenicity and safety in the Anti-TNF Failure population.
During the Double Blind ST Period, participants received IV abatacept infusions on Days 1, 15, 29, and every 28 days, thereafter for 6 months. A double-dummy design was used to protect the blind, thus, participants also received SC injections of placebo (SC Placebo).

Title Double-blind Period: Time-matched Median Percent Change From Baseline in Levels of Serum C-reactive Protein Over the Short-term Period
Hide Description C-reactive protein is an acute phase reactant protein that is a clinical marker for rheumatoid arthritis. Time-matched median percent change from baseline= (time-matched baseline value - Post-baseline value)/time-matched baseline value*100, where the time-matched baseline value represents the median baseline value for only that cohort of participants with measurements available at that visit.

Hide Arm/Group Description During the Main study Double Blind ST Period, participants received IV abatacept infusions on Days 1, 15, 29, and every 28 days, thereafter for 6 months. A double-dummy design was used to protect the blind, thus, participants also received SC injections of placebo (SC Placebo). An Anti-TNF Failure Sub-study was initiated (recruited separately from Main study) using the same treatment as the Main study in order to assess the immunogenicity and safety in the Anti-TNF Failure population. The Sub-study terminated due to low recruitment and participants were permitted to roll into the LT Open Label Period. During the Open Label LT Period, participants in both the Main Study and the Anti-TNF Failure Sub-study could switch to SC abatacept until the SC formulation became commercially available on a country basis or the Sponsor terminated the study. During the Main Study Double Blind ST Period, participants received 125 mg weekly SC abatacept injections for 6 months (with an IV abatacept loading dose on Day 1, based on weight). A double-dummy design was used to protect the blind, thus, participants also received IV injections of placebo (IV Placebo) with the exception that on Day 1 a loading dose of IV abatacept replaced the IV Placebo treatment. An Anti-TNF Failure Sub-study was initiated (recruited separately from Main study) using the same treatment as the Main study in order to assess the immunogenicity and safety in the Anti-TNF Failure population. The Sub-study terminated due to low recruitment and participants were permitted to roll into the LT Open Label Period. During the Open Label LT Period, participants in both the Main Study and the Anti-TNF Failure Sub-study could continue SC abatacept until the SC formulation became commercially available on a country basis or the Sponsor terminated the study.
