Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Tacrolimus
Drug: Tacrolimus
Patients receiving TAC were treated with a dose of 0.08-0.12 mg/kg/day orally in two divided doses with target trough whole blood concentrations of 10-15 ng/ml for the first month post-transplant followed by 5-10 ng/ml thereafter. Immunosuppression was typically tapered to monotherapy (TAC alone) within 4-6 months of transplantation.
Other Names:
  • Prograf
Active Comparator: Cyclosporine
Drug: Cyclosporine
Patients randomized to CsA had TAC discontinued and were treated with CsA at a dose of 2.0-4.0 mg/kg/day orally in two divided doses with target trough whole blood concentrations of 150-200 ng/ml.
Other Names:
  • Gengraf
