Study: NCT01729494

Intervention type: DRUG
Group type: EXPERIMENTAL
Intervention: Alemtuzumab
Description: Alemtuzumab will be dosed on day of transplant (Study Day 1) at dose of 30 mg given intravenously (IV) over a period of 2 hours after induction of anesthesia. Methylprednisolone IV will be administered 30-60 minutes prior to the administration of alemtuzumab.

Group type: EXPERIMENTAL
Intervention: rabbit antithymocyte globulin
Description: Rabbit antithymocyte globulin will be dosed post-operatively at a total cumulative dose of 4.0-6.0mg/kg given by days 5-10 post-transplant. It will be administered by local standards of care with the following recommendations. The initial intravenous intra-operative dose will be administered approximately one hour after the methylprednisolone dose. The first dose will be administered so that approximately 25% of the dose is infused prior to revascularization of the graft. Subsequent doses will be administered over a minimum of 4 hours. Premedication with acetaminophen 650mg p.o. and diphenhydramine 25mg p.o. prior to rabbit antithymocyte globulin dose will be given to reduce the incidence of infusion reactions.

Intervention: Belatacept
Description: Belatacept will be administered via intravenous (IV) infusion according to the FDA approved dosage recommendations. Subjects randomized to belatacept arms will receive the first dose of IV belatacept (10 mg/kg) within 12-24 hours post reperfusion. The second dose will be given between post-transplant days 4 -6 (Study Days 5-7), and then study days 14, 28, 56, and 84 (12 weeks) and then subjects will receive belatacept at the maintenance dose of 5 mg/kg every 4 weeks until completion of the trial at 24 months (104 weeks). Study Day 1 is defined as the day of transplant.

Intervention: Tacrolimus
Description: Tacrolimus will be administered orally twice daily (BID). The recommended total initial dose of tacrolimus is 0.1 mg/kg/day in two divided doses orally. Tacrolimus should be started post-transplant within 48 hours or when serum creatinine drops lower than 4mg/dL, whichever comes first. The initial targeted trough level of tacrolimus will be 8 - 12 ng/mL for Days 1 through 30, with dose reduction to achieve a 12-hour trough target of 5 - 10 ng/mL thereafter.

Intervention: Mycophenolate mofetil
Description: The first dose of mycophenolate mofetil/EC mycophenolate sodium will be administered pre-operatively. Patients receiving mycophenolate mofetil will be dosed 1000 mg twice daily (2000mg/day). Patients receiving EC mycophenolate sodium will be dosed 720 mg twice daily (1440 mg/day). Dose may be increased for African American transplant recipients to mycophenolate mofetil 1500 mg twice daily (3000mg/day) or EC mycophenolate sodium 1080 mg twice daily (2160 mg/day).
