Methotrexate-Inadequate Response Autoinjector Device Sub Study (MTX-IR)
June 30, 2015 updated by: Bristol-Myers Squibb
Substudy-A Phase IIIB Multicenter, Randomized, Double-Blind, Double-Dummy Study to Compare the Efficacy and Safety of Abatacept Administered Subcutaneously and Intravenously in Subjects With Rheumatoid Arthritis, Receiving Background Methotrexate, and Experiencing an Inadequate Response to Methotrexate
The purpose of this study is to implement a substudy in approximately 120 rheumatoid arthritis (RA) subjects to compare the steady-state serum trough concentration (Cminss), Cmax and area under the curve (AUC) during the dosing interval (TAU) of subcutaneous (SC) Abatacept injection of 125 mg via the autoinjector and via the BD Hypak™ Physiolis prefilled syringe.

Time Frame: Day 29, Day 113
|
Abatacept SC was self-administered with a prefilled syringe every 7 days for the first 4 weeks until Day 29; Blood samples for PK were taken pre-dose (0 hour) on Days 29 and 113.

Number of Participants With Positive Anti-Abatacept or Anti-CTLA4 Antibody Responses by Electrochemiluminescence (ECL) on Day 29 and Day 113.
Time Frame: Days 29 and 113
|
Serum samples for immunogenicity were evaluated for presence of anti-abatacept antibodies using a validated bridging ECL on Day 29 and Day 113.
The ECL assay differentiated between 2 antibody specificities: the immunoglobulin (Ig) G and/or junction region and cytotoxic leukocyte antigen 4 (CTLA4) and possibly Ig.
A positive immunogenicity response relative to baseline was defined as: A missing baseline immunogenicity measurement and a positive analytical laboratory reported immunogenicity response post-baseline; A negative baseline immunogenicity response and a positive analytical laboratory reported immunogenicity response post-baseline; A positive baseline immunogenicity response and a positive analytical laboratory reported immunogenicity response post-baseline that has a titer value strictly greater than the baseline titer value.
