Phase: Phase 2

Status: Recruiting

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.

Clinical Details

Official title: Prospective, Randomized, Double-Blind, Double-Dummy, Multicenter Trial to Assess Safety of Single Dose vs. Traditional Administration of Thymoglobulin Induction for Renal Transplantation

Study design: Allocation: Randomized, Endpoint Classification: Safety Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator), Primary Purpose: Treatment

Primary outcome: Composite endpoint of 5 components: Fever, Hypoxia, Hypotension, Cardiac Events, and Delayed Graft Function

Secondary outcome:

Patient Survival

Graft survival

Acute rejection of transplanted kidney; biopsy-confirmed, clinically symptomatic

Incomplete Thymoglobulin infusion

Short-term kidney function (Immediately after transplantation)

Longer-term kidney function

Hematologic effects of Thymoglobulin administration (Effects of the 2 different dosing plans on white and red blood cells and platelets)

Immunologic effects of Thymoglobulin administration (studies of antibodies and specific immune cell types in the blood after transplantation)

Histopathology of kidney biopsies taken at transplantation and after 12 months

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.


Minimum age: 18 Years. Maximum age: 65 Years. Gender(s): Both.


Inclusion Criteria:

the previous 6 months

- Current malignancy or history or malignancy (within the previous 5 years) with the

exception of non-metastatic basal or squamous cell carcinoma of the skin or carcinoma in-situ of the cervix that has been treated successfully.

- Hepatitis B and C recipients or active liver disease

- HIV positive recipients

- Primary disease requiring treatment with steroids after transplantation

- Expanded-criteria donor kidneys (current UNOS criteria) with a donor grade score of >

- Any condition that in the investigator's opinion may compromise study participation

(e. g., history or likelihood of non-compliance with immunosuppression regimen, protocol visits, tests, and studies) Relative Exclusion Criteria:

- Patients with a BMI > 37 should be considered on an individual basis based on overall

health and body habitus.
