NCT06055608

Brief Summary

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.

Study Arms (2)

(Group 1): Belatacept+Sirolimus group

EXPERIMENTAL

Participants in this group will receive antithymocyte globulin (ATG) + steroid taper + belatacept + (tacrolimus bridge, day 0-14) with conversion to sirolimus (day 30 +/-14 days)

Drug: SirolimusBiological: BelataceptDrug: Tacrolimus (Group1)Drug: Anti-Thymocyte Globulin (ATG)

(Group 2): Tacrolimus + Mycophenolate Mofetil (MMF) group

ACTIVE COMPARATOR

Participants in this group will receive anti-thymocyte globulin (ATG) + steroid taper + tacrolimus + MMF

Drug: Mycophenolate MofetilDrug: Anti-Thymocyte Globulin (ATG)Drug: Tacrolimus (Group 2)

Interventions

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

Also known as: AY 22-989, Rapamune, Rapamycin
(Group 1): Belatacept+Sirolimus group
BelataceptBIOLOGICAL

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

Also known as: Nulojix
(Group 1): Belatacept+Sirolimus group

Mycophenolate Mofetil-MMF will be initiated at 600 mg/m\^2 BID until tacrolimus is at therapeutic levels, then 450 mg/m\^2 BID

Also known as: CellCept, MMF
(Group 2): Tacrolimus + Mycophenolate Mofetil (MMF) group

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

Also known as: FK-506, FR-900506, Prograf
(Group 1): Belatacept+Sirolimus group

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

(Group 1): Belatacept+Sirolimus group(Group 2): Tacrolimus + Mycophenolate Mofetil (MMF) group

Also known as: FK-506, FR-900506, Prograf
(Group 2): Tacrolimus + Mycophenolate Mofetil (MMF) group
