About this study

Official title: A Randomized, Open-label, Comparative Evaluation of Conversion From Calcineurin Inhibitors to Sirolimus Versus Continued Use of Calcineurin Inhibitors in Renal Allograft Recipient

This study will evaluate whether conversion from cyclosporine, a calcineurin inhibitor (CI) to sirolimus (SRL) results in improved long-term renal function without a negative impact on safety or immunosuppressive efficacy, and to further examine the potential of SRL to reduce the severity and/or progression of chronic allograft nephropathy (CAN).

Read the detailed description

This open-label, randomized, parallel-group, comparative, outpatient study will be conducted in multiple centers in Taiwan.

The study will randomize approximately 120 patients. 80 patients will be randomized to the SRL therapy group (conversion from CI- to SRL-based immunosuppression: group A) and 40 patients to the CI therapy group (continued CI therapy: group B).

Dosage and Administration

SRL Therapy: At the time of randomization on day 1, each patient will have been receiving:

  • triple therapy with a CI (tacrolimus or CsA) that began at the time of transplantation or within 2 weeks thereafter AND
  • corticosteroids corresponding to a dosage range of 2.5 to 15 mg/day for prednisone or prednisolone (2 to 12 mg/day for methylprednisolone) or the alternate day equivalent for at least 12 weeks before randomization, PLUS
  • either MMF (minimum dose 500 mg/day)/MPS (minimum dose 360 mg/day) or AZA (minimum dose 50 mg/day) for at least 12 weeks before randomization.

SRL will be added to the immunosuppressive regimen for Group A. Group B will continue on this CI immunosuppressive regimen.

Being tested
Sirolimus+MMF or MPS or AZA+Steroid, Calcineurin Inhibitors (either cyclosporine or tacrolimus)+MMF or MPS or AZA+Steroid

What participants receive

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

  • Sirolimus+MMF or MPS or AZA+SteroidDrug

    Corticosteroids will be administered according to local practice, within a daily maintenance dosage range of 2.5 to15 mg for prednisone or prednisolone (2 to 12 mg/day for methylprednisolone) or the alternate day equivalent.

  • Calcineurin Inhibitors (either cyclosporine or tacrolimus)+MMF or MPS or AZA+SteroidDrug

    The maintenance dose of:

    1. MMF will not exceed 1500 mg/day or PMS will not exceed 1080 mg/day
    2. AZA will not exceed 75 mg/day

    Thereafter, at the discretion of the investigator, MMF/MPS or AZA may be:

    1. continued for the entire 104-week period of randomized therapy
    2. subsequently discontinued
    3. restarted after discontinuation

What is being measured

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

  1. Change in Glomerular Filtration Rate (GFR) Change From Baseline

    GFR is an index of kidney function. GFR describes the flow rate of filtered fluid through the kidney. GFR can be measured directly or estimated using established formulas. GFR was calculated using Nankivell formula. A normal GFR is > 90 mL/min, although children and older people usually have a lower GFR. Lower values indicate poor kidney function. A GFR <15 is consistent with kidney failure.

    Measured: 104 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Sirolimus+MMF or MPS or AZA+Steroid and Calcineurin Inhibitors (either cyclosporine or tacrolimus)+MMF or MPS or AZA+Steroid in people with Kidney Transplantation, run by Wyeth is now a wholly owned subsidiary of Pfizer at 1 site in Taiwan.

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 1 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 3 Sep 2012. 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 Taiwan. 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 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?

Yes. Results are posted in the registry (first posted 3 Sep 2012). 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?

Change in Glomerular Filtration Rate (GFR) Change From Baseline (time frame: 104 weeks). 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 3 Sep 2012.
