Study Arms (2)
Tacrolimus
ACTIVE COMPARATORCalcineurin inhibitor arm, consisting of treatment with tacrolimus, mycophenolate mofetil, and prednisone.
Sirolimus
ACTIVE COMPARATORCalcineurin inhibitor-free arm, consisting of treatment with rapamycin, mycophenolate mofetil, and prednisone.
Interventions
Thymoglobulin 1.5 mg/kg/d (days 0,1,2,4,6)
Mycophenolate mofetil 750 mg p.o. b.i.d.- maintenance
Prednisone 500 mg/day initially, tapered to 5 mg/day by day 92
Tacrolimus - maintain trough levels of 6-8 ng/ml (whole blood Imx assay)
Rapamycin 3 to 5 mg/day; adjust to the high-performance liquid chromatography (HPLC) blood level 15 to 20 ng ml
Eligibility Criteria
You may qualify if:
- Living and deceased donor kidney transplant recipients at the Mayo Clinic, Rochester, Minnesota
You may not qualify if:
- Patients with type 1 diabetes less than 50 years of age who receive a living donor kidney transplant followed by a pancreas transplant
- Pediatric patients (\<18 years of age)
- Multi-organ transplants (e.g., kidney-pancreas, kidney-liver)
- ABO-incompatible or positive crossmatch recipients (ABO incompatibility is an immune system reaction that occurs when blood from two different and incompatible blood types are mixed together.)
- Patients with severe hyperlipidemia (serum cholesterol \>350 mg/dl or serum triglycerides \>500 mg/dl
- Patients with severe leukopenia (White Blood Cell count \[WBC\]\<3000 10\^3/ml)
- Patients unwilling to return to the transplant center for late follow-up visits
- Body mass index (BMI) ≥ 32 with incisional problems post transplant (as determined by renal transplant surgeon
