Abatacept (CTLA4–Ig) is a novel fusion protein designed to modulate the T cell co-stimulatory signal mediated through the CD28–CD80/86 pathway. Clinical trials have provided preliminary evidence of the efficacy of this compound in the treatment of rheumatoid arthritis. This review describes the molecular and biologic bases for the use of abatacept in rheumatoid arthritis and summarizes the current clinical data on its safety and effectiveness in this disease.
