Trial summary

The investigators hypothesize that Tacrolimus (Tac) withdrawal from a Tac, MMF and steroid based triple therapy regimen leads to long term improved/stabilized graft function (glomerular filtration rate, GFR) primarily as a consequence of halting CNI-induced fibrogenetic processes that mediate loss of functioning renal… Read more about this study

About this study

Official title: Renal Allograft Function and Histology Following Switching From A Tacrolimus to Sirolimus (SRL)-Based Immunosuppression- Clinical and Mechanistic Impact

The investigators hypothesize that Tacrolimus (Tac) withdrawal from a Tac, MMF and steroid based triple therapy regimen leads to long term improved/stabilized graft function (glomerular filtration rate, GFR) primarily as a consequence of halting CNI-induced fibrogenetic processes that mediate loss of functioning renal tissue. The investigators further hypothesize that the underlying fibrotic mechanism is mediated by pathophysiologic processes that promote epithelial to mesenchymal transition (EMT) (mediated by TGF- ƒÒ) and that early therapeutic intervention may reverse this process (mediated by BMP-7)4.

To address these hypotheses the investigators propose the following clinical and mechanistic aims:

The investigators will test the hypothesis that switching from Tac to SRL in a Tac based triple therapy regimen with MMF and steroids in living and or deceased donor renal transplant recipients leads to improvement in allograft structure and function at 2 years post-transplantation.

The investigators will test this hypothesis in an open label controlled trial where stable renal allograft recipients on Tac, MMF, prednisone maintenance immunosuppression will undergo renal biopsy at 3-4 months post-transplantation and will be randomized to either a) Remain on Tac, MMF and prednisone (CNI-maintenance) or b) switch the Tac to SRL and continue MMF and prednisone. The investigators will then compare biopsy derived measures of allograft fibrosis (CADI, Sirius Red, Banff Chronicity Index) and GFR in the two groups

What is being measured

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

  1. Biopsy-derived Measures of Fibrosis

    The primary analyses will compare biopsy-derived measures of fibrosis in the Tac-maintenance and SRL groups using the t-test.

    Measured: 12 months

Secondary outcomes (1)
  1. Change in iGFR

    We will also compare the change in iGFR (as well as estimated GFR) from time of conversion to 12 and 24 months of follow up by paired t-test between groups.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Sirolimus and Tacrolimus in people with Kidney Transplant, run by The Cleveland Clinic at 1 site in United States.

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 4 inclusion and 17 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: stopped early, as of the sponsor's last update on 7 Jun 2017. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 7 Jun 2017). 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?

Biopsy-derived Measures of Fibrosis (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 7 Jun 2017; AzTrials last refreshed its copy on 6 Nov 2026.
