Description of intervention(s) / exposure
Treatment: Drugs - Tacrolimus
Treatment: Drugs - Sirolimus
Treatment: Drugs - Tacrolimus

Experimental: Group I - Planned transition to sirolimus from tacrolimus -

Active comparator: Group II - Continuation of tacrolimus -


Treatment: Drugs: Tacrolimus
During the screening phase, tacrolimus is provided by the investigator (not the Sponsor) and is dosed to achieve a target trough level determined by the investigator. Therefore, the dosage form, dosage, and frequency are determined by the investigator. Duration of treatment is from transplantation until randomization (from 90 to 150 days).

Treatment: Drugs: Sirolimus
Following randomization, sirolimus is provided by the Sponsor in 1 and 2 mg oral tablets. Sirolimus is dosed once daily to achieve a target trough level of 7 to 15 ng/mL in the 1st year post-transplant and 5 - 15 ng/mL in the 2nd year post-transplant. Duration of treatment is from randomization through 2 years post-transplant (19 to 21 months).

Treatment: Drugs: Tacrolimus
During the study, tacrolimus is provided by the investigator (not the Sponsor) and is dosed to achieve a target trough level determined by the investigator. Therefore, the dosage form, dosage, and frequency are determined by the investigator. Duration of treatment is 2 years post-transplant.

* Active post-operative complication, e.g. infection, delayed wound healing.
* Total white blood cell count less than 2,000/mm3 or absolute neutrophil count (ANC) less than 1000 or platelet count less than 100,000/mm3 less than or equal to 2 weeks prior to randomization.
* Fasting triglycerides greater than 400 mg/dL (greater than 4.5 mmol/L) or fasting total cholesterol greater than 300 mg/dL (greater than 7.8 mmol/L) less than or equal to 2 weeks prior to randomization regardless of whether or not on lipid-lowering therapy.
* Women who are biologically capable of having children with a positive urine or serum pregnancy test at randomization.
* Breastfeeding women.
