About this study

Official title: Identification and Mechanistic Investigations of Tolerant Transplant Recipients

The purpose of this multi-center (observational) registry study is to establish a database of clinical and laboratory information that may help to identify any unique characteristics of tolerant participants that differ from participants who reject their kidney after discontinuing immunosuppressive drugs.

Read the detailed description

Following kidney (renal) transplantation, one possible complication is rejection of the new kidney. This occurs as a results of the body's immune system attacking (or rejecting) the newly transplanted kidney. After transplant, medicines known as "immunosuppressive" or "anti-rejection" drugs are given to transplant recipients to help prevent rejection of the transplanted kidney. If a transplant recipient stops taking these medicines, they almost always reject their transplanted kidney. However, in some exceptionally rare instances, transplant recipients who stop taking these drugs do not reject their kidney, and the kidney keeps working. The recipients are said at that point to "tolerate" the transplanted kidney, and this condition is referred to as "tolerance".

In this study, participants will be asked to provide consent for the collection of extensive demographic and clinical information; medical histories; and blood and urine samples. Blood and urine samples collected will be used to perform specific assays to help define mechanisms of tolerance.

Originally the study included 11 groups as listed; however, at present only groups 1,4, and 8 remain active. Whereas the initial study duration was 6 years, this was extended to 11 years in order to follow over more extended time a B cell signature identified for tolerant kidney subjects and how this signature may change. (Refer to publications section: Newell, Kirk et al, J Clin Invest. 2010).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT01338779
Study groupRoleWhat they receive
Group 1 - kidney tolerantRenal allograft recipients showing functional tolerance (normal and stable renal function) after discontinuation of immunosuppressive medications for at least 1 year (or based on the investigator's discretion).
Group 2 - acceptorEnrollment for group 2 was closed. Renal transplant recipients with functioning allografts (not on dialysis) who had not received immunosuppressive medications for at least 1 year (or at investigator's discretion) but who had moderately impaired or gradually deteriorating renal function, defined as creatinine clearance (CrCl) < 40 mL/min and/or creatinine > 50% above baseline value, and thus did not qualify for group 1.
Group 3 - kidney graft lossEnrollment for group 3 is closed. These were renal transplant recipients who had subsequently rejected and lost function of their transplanted kidney.
Group 4 - kidney monotherapyRenal transplant recipients showing stable and normal renal function after receiving only prednisone 10 mg/day for at least 1 year (or based on the investigator's discretion).
Group 5 - kidney standard immunotherapyEnrollment for group 5 is closed. Stable renal transplant recipients currently on standard immunosuppression.
Group 6 - kidney chronic rejectorEnrollment for group 6 is closed. Chronic allograft nephropathy group.
Group 7 - kidney identical twinEnrollment for group 7 is closed.
Group 8 - living kidney donorsCorresponding to recipients in group 1 or 4.
Group 9 - healthy controlsEnrollment for group 9 is closed.
Group 10 - liver tolerantEnrollment for group 10 is closed. Liver allograft recipients with functional tolerance (stable and normal liver function) after cessation of immunosuppressive medications for at least three years (or at investigator's discretion).
Group 11 - liver standard immunotherapyEnrollment for group 11 is closed. Subjects with a liver transplant who never had an attempt made to discontinue gradually their immunosuppression and who are currently taking standard immunosuppressive medications and have stable and normal liver allograft function after at least 1 year of receiving these drugs.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To identify individuals who have received a kidney transplant and who have achieved a state of immune tolerance to graft

    Measured: 0 to 11 years

  2. To create an electronic registry of data on the tolerant and comparison groups that will serve as the basis for statistical analyses

    Measured: 0 to 11 years

  3. To use data from the registry to perform classical tests of hypotheses regarding the establishment of immune tolerance

    Measured: 0 to 11 years

  4. To use data from the registry to create and assess predictive statistical models to model such variables as clinical features, duration of tolerant state, and time to onset of immune sensitization

    Measured: 0 to 11 years

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 6 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 30 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

To identify individuals who have received a kidney transplant and who have achieved a state of immune tolerance to graft (time frame: 0 to 11 years). The study lists 4 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 NCT01338779, which also lists 6 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 30 Sep 2016.
