  • Testosterone levels [ Time Frame: Months 6, 12, 18 and 24 ] [ Designated as safety issue: Yes ]
  • Quality of life [ Time Frame: Months 6, 12, 18 and 24 ] [ Designated as safety issue: Yes ]

Study Start Date: September 2009
Estimated Study Completion Date: January 2011
Estimated Primary Completion Date: January 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Conversion to sirolimus Drug: Sirolimus (Rapamune)
Started at 5 mg (Target levels 6-10mg/mL), Daily, PO, 24 months
Other Name: RAPAMUNE
Active Comparator: Calcineurim inhibitor reduction Drug: Cyclosporin (Neoral) or Tacrolimus (Prograf)

Cyclosporin: 3-4 mg/kg, BID, PO, 24 months

Tacrolimus: 0-.038-0.045 mg/kg, BID, PO, 24 months

Other Names:
  • Cyclosporin: NEORAL
  • Tacrolimus: PROGRAF

Detailed Description:

This study is designed to support the optimal use of mTOR-inhibitor by providing data for the safe and effectiveness use with sirolimus. This study will take into account effectiveness aspects such as malignancy-free survival cancer by reducing the overall exposure to calcineurin inhibitor.
