About this study

Official title: Differentiating Sirolimus and Everolimus in Combination With Calcineurin Inhibitors in Long-term Maintenance of Kidney Transplant Patients - The Effects on Vascular Endothelial and Kidney Function. The DESIRE Study.

The investigators hypothesize that switching kidney transplant patients on tacrolimus/sirolimus long-term maintenance immunosuppressive drug regimens to tacrolimus/everolimus, will not only be safe, but will lead to better kidney function than patients staying on tacrolimus/sirolimus due to the lower potential of everolimus to enhance calcineurin inhibitors toxicity and/or its ability to even reverse some of the negative effects of calcineurin inhibitors on vascular endothelial and kidney function. To test this hypothesis vascular endothelial biomarkers will be analyzed in blood plasma samples and kidney dysfunction biomarkers in urine samples via liquid chromatography tandem mass spectrometry to evaluate whether switching kidney transplant patients on tacrolimus/sirolimus to tacrolimus/everolimus will lead to better kidney and endothelial function after one year and two years.

What participants receive

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

  • EverolimusDrug

    Also called Zortress

    Patients will be stable kidney transplant patients who are receiving an immunosuppressive drug regimen based on tacrolimus and sirolimus. 24 hours after the last sirolimus dose, the patients randomized to the tacrolimus/everolimus arm of the study will be switched from sirolimus to everolimus 1:1 (same sirolimus as everolimus dose). Everolimus doses will be adjusted so that trough blood concentrations are within 3-8 ng/mL. In detail: Tacrolimus (Prograf or FDA approved generic 0.5 mg, 1 mg or 5 mg capsules, twice a day) in combination with Everolimus (Zortress, 0.25, 0.5 and 0.75 tablets).

  • SirolimusDrug

    Patients will be stable kidney transplant patients who are receiving an immunosuppressive drug regimen based on tacrolimus and sirolimus. 24 hours after the last sirolimus dose, the patients randomized to the tacrolimus/sirolimus arm of the study will remain on tacrolimus/sirolimus. In detail: Tacrolimus (Prograf or FDA approved generic 0.5 mg, 1 mg or 5 mg capsules, once a day) in combination with Sirolimus (Rapamune, 0.5, 1, and 2mg tablets).

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Everolimus and Sirolimus in people with Kidney Transplantation, run by University of Colorado, Denver.

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 6 inclusion and 13 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: withdrawn, as of the sponsor's last update on 2 Dec 2014. Status can change between updates, so confirm with the study contact before making plans.

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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Creatinine Outcome Measure (1) (time frame: 1 year). The study lists 10 primary outcomes in all. 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 2 Dec 2014; AzTrials last refreshed its copy on 8 Nov 2026.
