This study evaluates two potential improvements to the standard immunosuppression regimen used at the investigators' institution to prevent rejection of transplanted kidneys. These two potential improvements are each applied in sequence to half of the study patients, creating 4 study arms; the other half receive the standard treatment. The two potential improvements are: 1. Administering the immunosuppression induction agent rATG ("rabbit anti-thymocyte globulin") in a single dose at the time of transplantation, instead of in the usual series of 4 smaller doses over 6 days. 2. After 6 months, modifying the maintenance immunosuppression used to prevent rejection by replacing the drug tacrolimus with mycophenolate mofetil (MMF).

Study summary:

The two treatment innovations in this study of immunosuppression in kidney transplantation are aimed at making the transplanted kidney function sooner and last longer than is usual with standard immunosuppression regimens, but without increasing the likelihood of rejection. The first innovation, delivering the induction agent rATG in a single large dose rather than as a series of smaller doses over 6-8 days, is expected to produce better graft function right away, possibly by reducing some of the injury to the kidney that accompanies the restoration of blood flow during transplantation ("reperfusion injury"). Some evidence has been developed by investigators elsewhere to suggest this will happen. The second innovation, replacing tacrolimus with MMF after 6 months, is intended to eliminate a well-established major cause of ongoing toxic damage to the kidney. While tacrolimus does a good job of preventing rejection, the cost in continuing toxic injury to the kidney is high, leading inevitably to eventual graft failure, the inability of the transplanted kidney to continue filtering the blood and making adequate volumes of high-quality urine.
