Description:Abatacept (CTLA4lg) is a soluble fusion protein consisting of the extra-cellular domain of human CTLA4 and a fragment of the Fc portion of human IgG1 (hinge and CH2 and 3 domains). Abatacept is a selective T-cell co-stimulation modulator and a protein agent for the autoimmune diseases.

In Vivo:Abatacept reduces paw edema, and the SC Multiple-dose group shows significantly greater (tobs = 2.50) paw edema reduction compared with the IV dose group[2]. Abatacept exhibits linear PK across the studied doses. The NCA clearance (CL) is 20.8 mL/day/kg, volume (Vss) is 146 mL/kg, and bioavailability (F) of the SC dose dosing is 57.7%[2]. Abatacept (oral; 10 mg/kg; every 2 days) reduces the proportion of activated T cells (CD44highCD62L–) and inhibits the up-regulation of ICOS and CD71 in homozygous DO11.10 RAG-2–/– BALB/c (H-2d/d) mice[3].
