Official title

Prospective, Randomized 2 x 2 Factorial Trial of Rabbit Anti-thymocyte Globulin Induction (Single vs. Alternate Day Administration) at Renal Transplantation, With Delayed Calcineurin-inhibitor Withdrawal vs. Minimization

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This 2 x 2 sequential factorial 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). The two interventions, spaced sequentially six months apart, enable independent analysis of the two treatments so long as it can be shown that there is no synergistic interaction between them.
