Study Summary

The purpose of this study is to determine whether immunosuppression by tacrolimus, mycophenolate mofetil, and prednisone compared to conversion to sirolimus, mycophenolate mofetil, and prednisone affect the progression of atherosclerosis in renal transplant recipients.

Primary Outcome

Within-subject annual change rate in TPV in the left and right distal common carotid arteries from the pre-conversion baseline to 12 months post kidney transplant as determined by ultrasound. Annual change rate equals (=) (TPV at month 12 post-transplant minus \[-\] TPV at pre-conversion baseline) divided (/) by imaging interval in years. TPV is the sum of assessment in left and right distal common carotid arteries.

Interventions

  • DRUG prednisone
  • DRUG tacrolimus
  • DRUG sirolimus
  • DRUG mycophenolate mofetil
