Graft Survival [ Time Frame: 3 years ]

20 renal transplant patients who received a renal biopsy for graft dysfunction and were found to have pure CAN (no other pathologic findings on biopsy) were randomized in a 2:1 fashion to convert to rapamycin (goal 24 trough 5ng/ml) or remain on their CNI with low target serum levels (50ng/ml-125ng/ml 12 hr trough). The patients were asked to undergo a second biopsy at the end of their follow up period (minimun 3 years). Patients underwent a DTPA nuclear study to obtain an accurate GFR at study entry and repeated the nuclear study at the end of the study to determine the change in creatinine clearance in an accurate manner. In addition, laboratories were obtained at predetermined intervals.

Univariat analysis resulted in the primary end-point of improved graft survival not being statistically achieved with conversion to Rapamycin. seconday end points of renal function measured directly by dtpa, calculated by MDRD equation and histologic (biopsy) interstitial fibrosis was no

Mycophenolate Mofetil and Rapamycin as Secondary Intervention vs. Continuation of Calcineurin Inhibitors in Patients at Risk for Chronic Renal Allograft Failure
A study to determine the effect on renal function in renal transplant patients with biopsy proven CAN nephropathy who are switched from a CI triple drug regimen to a Rapamycin based triple drug regimen or maintained on their CI protocol
Not Provided
Interventional
Phase 4
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: No masking

Kidney Transplant
Drug: Rapamycin
Rapamycin will start within 24 hours of last calcineurin inhibitors (Cya, Prgraf). Initial dose of Rapamune 10mg will be given for 3 days and then dose will be adjusted to attain a target whole blood trough of 5-15
Other Name: Sirolimus
  • Active Comparator: 1
    pt will switch from calcineurin inhibitor (CYA, prograf) to Rapamycin
    Intervention: Drug: Rapamycin
  • No Intervention: 2
    Patient will remain on calcineruin inhibitor
