A Phase II Study of Belatacept (BMS-224818) With a Steroid-free Regimen in Subjects Undergoing Kidney Transplantation

27 de maio de 2014 atualizado por: Bristol-Myers Squibb

A Randomized, Open-Label, Multicenter, Parallel-Group Study of Belatacept (BMS-224818)-Based Corticosteroid-Free Regimens in Renal Transplant

The purpose of this clinical research study is to learn if belatacept (BMS-224818) is expected to show acceptable rates of acute rejection (AR) in steroid-free belatacept-based immunosuppressive regiments compared to a similar steroid-free tacrolimus regimen. The long-term safety and tolerability of belatacept based regimens following long-term administration in subjects who have received a kidney transplant
