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

27 novembre 2013 aggiornato da: 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).

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: 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.

BPAR includes all cases in which a biopsy was read by the central pathologist as demonstrating acute rejection regardless of the reason why the biopsy was performed. PAR is defined as an elevation in SCr ≥0.5 mg/dL compared with the baseline value in the absence of other factors known to adversely affect renal function that led the investigator to suspect that the participant had experienced acute rejection, and in whom either the biopsy did not confirm acute rejection and the participant received treatment for acute rejection or the participant received treatment for acute rejection without a biopsy to confirm the diagnosis.
