Abstract

Belatacept is a second-generation cytotoxic T-lymphocyte-associated antigen-4-Ig fusion protein, which down-regulates T-cell response, and is used in the prophylaxis of organ rejection in adults receiving a kidney transplant. This article reviews the pharmacologic properties of belatacept and its clinical efficacy and tolerability in kidney transplant recipients. In the well designed, phase III trials BENEFIT and BENEFIT-EXT (in patients receiving kidneys from living/standard-criteria or extended-criteria donors, respectively), a belatacept-based treatment regimen was noninferior to a cyclosporine (ciclosporin)-based regimen with regard to patient and graft survival and acute graft rejection rate, and was significantly superior to the cyclosporine-based regimen with regard to the rate of renal impairment (in BENEFIT only), at 12 months. Belatacept-based treatment showed long-term efficacy and remained effective after 2, 3, and 4 years with regard to these endpoints. Belatacept was generally well tolerated in patients with kidney transplants from living, standard-criteria, or extended-criteria donors. The most serious adverse events that have been reported with belatacept treatment are post-transplant lymphoproliferative disorder, other malignancies, and serious infections. At month 12, the incidence of new-onset diabetes mellitus after transplant was significantly lower with belatacept than with cyclosporine, and belatacept recipients had significantly lower blood pressure and a significantly smaller increase in certain lipid levels than cyclosporine recipients.
