To assess equivalence in the rates of functional graft survival at 12 months after transplantation in patients receiving induction therapy with cyclosporin (CsA, Neoral) and Rapamune® followed by CsA dose reduction and concentration-controlled Rapamune® versus induction with CsA and Rapamune® followed by discontinuation of CsA and concentration-controlled Rapamune®.

Inclusion Criteria:

• Age: = to ≥ 18 years.
• End-stage renal disease, with patients scheduled to receive a primary or secondary renal allograft from a cadaveric donor, from a living-unrelated donor, or from a living-related donor.
• Patients with second and subsequent transplants must have maintained their primary graft for at least 6 months after transplantation (with the exception of graft failure due to technical reasons).

Exclusion Criteria:

• Evidence of active systemic or localised major infection prior to initial Rapamune® administration.
• Evidence of infiltrate, cavitation, or consolidation on chest x-ray obtained during screening.
• Use of any investigational drug or treatment up to 4 weeks prior to enrolling in the study and during the 12-month treatment phase. Exception: the use of erythropoiesis stimulating products. In these cases, erythrocyte-stimulating products must be discontinued prior to administration of Rapamune®.
