Trial 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. Read more about this study

About this study

Official title: Sirolimus Monotherapy to Optimize Activation Induced Cell Death (AICD) in Renal Transplants Following Lymphocyte Depletion Induction With Thymoglobulin

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 aft...

Read the detailed description

This protocol will test a novel dual agent combination therapy for its ability to prevent human renal allograft rejection. Thymoglobulin (Sangstat), a FDA-approved polyclonal rabbit-IgG antithymocyte preparation, will be given for ten days at the time of transplantation to achieve profound lymphocyte depletion. This will be paired with chronic therapy with Sirolimus (rapamycin, Wyeth-Ayerst), an oral immunosuppressant agent recently approved by the FDA. Rapamycin allows for antigen specific T cell activation but prevents T cell clonal expansion by interrupting IL-2 receptor beta-chain signal transduction. The rationale for this combination is to eliminate existing alloreactive T cell clones that could initiate a rejection at the time of transplantation, and to promote graft specific activation induced cell death (AICD) in repopulating T cells such that an allospecific T cell deficit is induced. The desired effect of this therapy is to prevent allograft rejection without the chronic use of calcineurin inhibitors or glucocorticosteroids, and in doing so, develop a regimen for transplantation that avoids most of the chronic drug toxicities inherent in the use of these two classes of immunosuppressants.

Twenty people will be evaluated in this pilot protocol. Ten will receive living donor kidney allografts and ten will receive cadaveric kidney allografts. Patients will be treated with Thymoglobulin beginning prior to graft implantation and continuing for ten days. Glucocorticosteroids will be given during the Thymoglobulin treatment to limit monocyte activation and prevent the cytokine release syndrome associated with this antibody preparation. Patients will be given Sirolimus orally beginning the day after transplantation and continuously thereafter. Patients will then be monitored for evidence of allograft rejection using standard functional parameters and protocol allograft biopsies. In addition, patients will be followed for a specific desired effect, allospecific AICD, that should promote the development of allospecific graft tolerance. This will be accomplished by assaying peripheral blood and allograft biopsies for apoptosis and peripheral blood for evidence of alloreactive T cell clone depletion.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 11 Feb 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Serum Creatinine Concentration (time frame: 6 months after intervention). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00006178, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Sep 2019.
