- Title:
Sirolimus Monotherapy to Optimize Activation Induced Cell Death (AICD) in Renal Transplants Following Lymphocyte Depletion Induction with Thymoglobulin
- Number:
00-DK-0196
- Summary:
This study will test the safety and effectiveness of two drugs, Sirolimus and Thymoglobulin, for preventing rejection of transplanted kidneys. Standard anti-rejection therapy uses a combination of drugs, such as cyclosporine, tacrolimus, azathioprine, steroids, and others, that are taken daily for life. However, even with this daily therapy, more than half of kidney recipients slowly reject their transplant within 10 years. Both Thymoglobulin, an antibody, and Sirolimus, an anti-rejection drug, prevent rejection by lowering the response of the immune system to the transplanted organ. Thymoglobulin is given in the pre- and postoperative period, and Sirolimus is taken long term.
Patients who receive a kidney transplant at the National Institutes of Health Clinical Center are eligible for this study. Candidates will be screened with a medical history, physical examination, and blood and urine tests.
Participants will undergo a kidney transplant. Before the surgery, a central line (intravenous catheter), through which blood and medicine can be given, is placed in the neck or chest. Patients may also undergo leukapheresis, a procedure for collecting white blood cells. The cells can be stored for transfusion later if white cell counts drop following Thymoglobulin treatment. For this procedure, blood is drawn from a needle placed in the arm and flows into a machine that separates the blood components by spinning. The white cells are collected in a bag and the red cells and plasma are returned through a second needle in the other arm.
Thymoglobulin will be given intravenously the day before the transplant and days 1 through 9 after the operation. Sirolimus will be taken by mouth, mixed with water or orange juice. Sirolimus therapy starts the day of the transplant and continues for life.
Follow-up study visits will be scheduled weekly for the first month after the transplant, then every 6 months for 1 year and then once a year for 4 years. Procedures during these visits may include blood and urine tests, physical examination, and check of vital signs (i.e., blood pressure, heart rate, breathing rate, temperature). Kidney biopsies (removal of a small piece of tissue for examination under the microscope) will be done at 2 weeks, 1 month and 6 months after surgery and then yearly for 4 years to check for any damage to the kidney. In addition, a local doctor will do routine laboratory tests 2 to 3 times a week for the first 2 to 3 months after transplantation, then weekly for several additional months, and at least monthly for life.
