Methotrexate-Inadequate Response Autoinjector Device Sub Study (MTX-IR)

30. Juni 2015 aktualisiert von: 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.

Primäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Pharmacokinetic (PK) Analysis: Adjusted Geometric Mean Observed Serum Trough Concentration at Steady State (Cminss) of Abatacept Using a Prefilled Syringe (Measured on Day 29) and Using an Autoinjector (Measured on Day 113)
Zeitfenster: 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. Serum concentrations of abatacept were analyzed using a validated enzyme-linked immunosorbent assay (ELISA). Steady-state trough observed concentration in serum (Cminss) was measured in micrograms/milliliter (μg/mL). Adjusted geometric mean and 90% confidence interval (CI) are presented.

Number of Participants With Positive Anti-Abatacept or Anti-CTLA4 Antibody Responses by Electrochemiluminescence (ECL) on Day 29 and Day 113.
Zeitfenster: 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.
