In a non-blinded pilot study conducted at the University of Nebraska Medical Center, evidence was found that a single large dose of Thymoglobulin on the day of kidney transplantation produced better kidney function than the standard dosing plan, when the same amount is divided into smaller doses on 4 days. This new study repeats that dose comparison, but with double-blinding and at multiple transplantation centers.

Secondary Outcome Measures:
  • Patient Survival [ Time Frame: 12 months post-transplantation ] [ Designated as safety issue: Yes ]
  • Graft survival [ Time Frame: 12 months post-transplantation ] [ Designated as safety issue: Yes ]
  • Acute rejection of transplanted kidney; biopsy-confirmed, clinically symptomatic [ Time Frame: 12 months post-transplantation ] [ Designated as safety issue: Yes ]
  • Incomplete Thymoglobulin infusion [ Time Frame: First 7 days post-transplantation ] [ Designated as safety issue: Yes ]
  • Short-term kidney function (Immediately after transplantation) [ Time Frame: Post-transplantation days 1-4 ] [ Designated as safety issue: No ]
  • Longer-term kidney function [ Time Frame: Post-transplantation months 3 - 12 ] [ Designated as safety issue: No ]
  • Hematologic effects of Thymoglobulin administration (Effects of the 2 different dosing plans on white and red blood cells and platelets) [ Time Frame: 12 months post-transplantation ] [ Designated as safety issue: Yes ]
  • Immunologic effects of Thymoglobulin administration (studies of antibodies and specific immune cell types in the blood after transplantation) [ Time Frame: 12 months post-transplantation ] [ Designated as safety issue: No ]
  • Histopathology of kidney biopsies taken at transplantation and after 12 months [ Time Frame: 12 months post-transplantation ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: Single-dose Thymoglobulin
Patients will receive 6 mg of Thymoglobulin per kilogram of body weight, all on the day of kidney transplantation
Drug: Anti-thymocyte Globulin (rabbit) (rATG) (Thymoglobulin)
6 mg of rATG administered in a single dose on the day of kidney transplantation
Active Comparator: Divided-dose Thymoglobulin
Patients will receive 6 mg of Thymoglobulin per kilogram of body weight, divided into 4 equal 1.5 mg/Kg doses, administered on 4 sequential days beginning on the day of kidney transplantation.
Drug: Divided-dose Thymoglobulin administration
6 mg/Kg total Thymoglobulin dose administered as 1.5 mg/Kg doses on 4 sequential days, beginning on the day of kidney transplantation.

Detailed Description:

Two randomized groups of kidney transplant recipients will be each administered the drug Thymoglobulin according to a different dosing regimen. The control group will receive the usual and traditional regimen of a total of 6 mg/Kg divided into 4 doses, 1 on the day of transplantation and 1 each day on the next 3 days. The experimental group will receive the same total Thymoglobulin dose, 6 mg/Kg, but entirely on the day of transplantation.

The study will be double-blinded, with placebo doses of Thymoglobulin administered as needed to enrollees in the experimental group. Enrollment is targeted at 165, with 150 subjects needed to complete the study for adequate evaluation.
