Belatacept Pilot Study in Lung Transplantation Immunosuppression in Lung Transplantation

Belatacept will be dosed at 10 mg/kg of actual body weight on days 0, 7, 14, 28, 56, and 84 then at 5 mg/kg on day 112 and every 28 days through day 364 (i.e., on days 140, 168, 196, 224, 252, 280, 308, 336, and 364)

Tacrolimus will be dosed enterally or sublingually within 48 hours of transplantation and the dose will be adjusted to target a trough blood level of 8-15 ng/ml

Anti-thymocyte globulin will be dosed intravenously at 3 mg/kg divided into 3 daily doses starting on day 0 after transplantation

Mycophenolate mofetil will be dosed at 1000 mg twice daily (or if the enteric coated formulation is used, this will be dosed at 720 mg twice daily. In the standard of care arm, mycophenolate mofetil will be initiated on day 0 after transplantation, whereas in the belatacept-based immunosuppression arm, mycophenolate mofetil will be initiated on day 90 after transplantation

Methylprednisolone 500 mg will be given intravenously before perfusion of the allograft during the transplant procedure, then methylprednisolone 0.5 mg/kg will be given intravenously twice daily for 6 total doses

Prednisone will be dosed at 0.5 mg/kg orally daily through day 14, then 0.2 mg/kg orally daily through day 30, then 0.1 mg/kg daily through day 180, then 5 mg daily through day 365
