Abatacept

Abstract

In December 2005, abatacept (Orencia; Bristol-Myers Squibb), a fusion protein that selectively modulates a costimulatory signal necessary for T-cell activation, was approved by the US FDA for the treatment of patients with rheumatoid arthritis who have had an inadequate response to other drugs. It is the first selective costimulation modulator to be approved.
