This is a pediatric kidney transplant study comparing the safety and efficacy of an immunosuppressive regimen of belatacept and sirolimus to tacrolimus and Mycophenolate Mofetil (MMF). Two hundred participants will be randomized (1:1) to one of two groups within 24 hours following the transplant procedure. The duration of the study from time of transplant to the primary endpoint is 12-24 months.
Inclusion Criteria: 1. Participant and/or parent/guardian must be able to understand and provide informed consent 2. Male or female, 13-20 years of age at time of enrollment 3. Candidate for primary renal allograft from a living or deceased donor 4. EBV IgG seropositive, defined as evidence of acquired immunity shown by the presence of IgG antibodies to viral capsid antigen (VCA) and EBV nuclear antigen (EBNA) 5. EBV VCA IgM seronegative OR EBV VCA IgM seropositive on two occasions at least 3 months apart and an undetectable EBV PCR result within 1 month prior to enrollment 6. If a female par…
Participants in Group 1 will transition to sirolimus therapy on day 14 (+/- 5 days) - weight \<40 kg will receive 3mg/m\^ 2, with maintenance dose of 1 mg/m\^2 divided BID - weight \>= 40kg will receive 6mg/m\^ 2, with maintenance dose of 2 mg daily
Belatacept will be administered as an intravenous infusion over 30 minutes. The belatacept dose for the study is 10 mg/kg on post-operative day (POD) 1, 5, 14, 28, 56, 84 for the first 3 months, followed by 5 mg/kg every 4 weeks (+/-4 days), starting on month 4 until month 24
Mycophenolate Mofetil-MMF will be initiated at 600 mg/m\^2 BID until tacrolimus is at therapeutic levels, then 450 mg/m\^2 BID
Participants will receive Prograf® (tacrolimus), or generic, initiated at 0.1 mg/kg BID within 48 hours of transplantation to attain target trough levels. Participants in Group 1 will be transitioned to sirolimus 2-4 weeks post-transplant
Participants will receive induction therapy with anti-thymocyte globulin (1.5 mg/kg/dose, maximum 125 mg) starting intraoperatively on day 0 and continuing on days 2 and 3 (total dose 4.5 mg/kg). Total dose may be extended to 6 mg/kg over 1-2 days for delayed graft function
Participants will receive Prograf® (tacrolimus), or generic, initiated at 0.1 mg/kg BID within 48 hours of transplantation to attain target trough levels
