Study Comparing the Safety and Efficacy of Belatacept With That of Cyclosporine in Patients With a Transplanted Kidney

27 novembre 2013 mis à jour par: Bristol-Myers Squibb

Phase II/III, Open-Label, Randomized, Controlled, Multiple-Dose Study of Efficacy and Safety of BMS-224818 (Belatacept) as Part of a Quadruple Drug Regimen in First Renal Transplant Recipients

The purpose of this study is to determine whether treatment with Belatacept (BMS-224818) is as efficacious as treatment with cyclosporine at preventing acute rejection and with a superior safety/tolerability profile (better kidney function and blood pressure, fewer lipid problems, less diabetes mellitus).

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Expérimental: Belatacept: More intensive (MI) regimen
The MI regimen was designed to achieve projected serum trough concentrations of belatacept of approximately 20 μg/mL through Day 99, and approximately 5 μg/mL through Day 183 (10 mg/kg on Days 1, 5, 15, 29, 43, 57, 71, 85, 113, 141, and 169). After Day 169, patients were reallocated and dosed to achieve projected trough serum concentrations of approximately 2 or 0.25 μg/mL (5 mg/kg every 4 or 8 weeks starting on Day 197). Those patients who received belatacept every 8 weeks received placebo infusions on scheduled treatment dates between infusions of active drug to maintain the blind between treatment regimens. Patients initially received mycophenolate mofetil (MMF), 2 g/d orally, unless the investigator chose to administer ≥1 doses intravenously The first MMF dose was administered preoperatively; subsequent doses were administered in 2 or 3 divided doses, every 8-12 hours, beginning as soon as the patient was able to tolerate medications by mouth. Corticosteroids given daily.

Expérimental: Belatacept: Less intensive (LI) regimen
The LI regimen was designed to achieve projected trough serum concentrations of belatacept of approximately 20 μg/mL through Day 29, and approximately 5 μg/mL through Day 99 (10 mg/kg on Days 1, 15, 29, 57 and 85).
