Abatacept: a novel treatment for rheumatoid arthritis

Rheumatoid arthritis (RA) is a chronic, autoimmune disease that has traditionally been treated with non-biologic and biologic disease-modifying antirheumatic drugs (DMARDs). Although these agents have become firmly established as effective RA treatments, some patients do not have an adequate response. The recent approval of abatacept, a first-in-class agent that selectively modulates the activation of T cells, offers an alternative therapeutic option. As reflected in pharmacokinetic analyses, abatacept 10 mg/kg has been shown to be effective in treating patients with established RA. Demonstrating safety, efficacy and quality of life improvements in a wide range of RA patients, including those with inadequate response to methotrexate or tumor necrosis factor antagonists, abatacept is seen as a valuable addition to the RA treatment armamentarium.
