NCT01516177

Brief Summary

This is an observational study for people who have received a kidney transplant within the past 1 to 5 years. Researchers in this study are looking for a certain pattern of genes and cells in the blood that has been found in a group of rare transplant patients who do not need immunosuppression. The study goal is to find out how common this pattern is in transplant patients, as a first step in determining if it can be used to personalize anti-rejection drug regimens better.

Outcome Measures

Primary Outcomes (1)

  • The presence of at least one time point of the previously identified renal transplant tolerance signature.

    2 years

Secondary Outcomes (4)

  • Time course of potential changes in the previously identified renal transplant tolerance signature in individual participants.

    2 years

  • Expression levels for a wide variety of genes measured by large-scale microarray or by PCR assessments

    2 years

  • Flow-cytometric measurements of cell populations distinguished by cell-surface phenotype

    2 years

Study Population

The study will include 250 participants who are determined to be eligible for further follow-up based on the eligibility criteria. Among those eligible for further follow-up * at least 25 participants will be renal transplant recipients who received induction therapy with Campath, and * at least 25 participants will be renal transplant recipients who are receiving sirolimus or everolimus at time of enrollment and who have not received calcineurin inhibitors for at least 30 days prior to enrollment

You may qualify if:

  • Received first kidney transplant from a living or deceased donor.
  • Kidney transplanted between 1 and 5 years ago.
  • Calculated GFR of greater than or equal to 45 mL/min/1.73 m2 within last 6 months
  • Ability to understand and provide informed consent.

You may not qualify if:

  • History of steroid-resistant acute rejection
  • History of two or more episodes of acute rejection
  • Any acute rejection in the past year
  • Current malignancy
  • Transplant of another organ
  • AIDS according to the CDC definition of AIDS.
