About this study

Official title: Comparison of a Tacrolimus/Sirolimus/Prednisone Regimen Versus Tacrolimus/Azathioprine/Prednisone Immunosuppressive Regimen in Lung Transplantation

The purpose of this study is to compare the safety and effectiveness of two different anti-rejection drug regimens.

Read the detailed description

This multicenter prospective, randomized controlled clinical trial compared the open label use of sirolimus with that of azathioprine in a tacrolimus-based immunosuppression regimen. Eligible patients were identified during a 90-day screening period immediately after transplantation and randomized via a computer-generated scheme. Patient randomization was stratified according to center and rejection status in the first 90 days after transplantation. All patients received IL-2 receptor antagonist induction therapy, tacrolimus, azathioprine, and corticosteroids until 90 days after transplantation. At 90 days after transplantation, patients were randomized at a 1:1 ratio to either continue azathioprine or change from azathioprine to sirolimus.

The dosing and levels of immunosuppressive medications were standardized for all patients included in this study. Tacrolimus was dosed at 0.04 mg/kg twice daily with target trough levels between 5 and 15 ng/ml, azathioprine was administered at 2 mg/kg daily with dose adjustments for leukopenia, sirolimus was initially dosed at 2 mg/day with target trough levels between 5 and 15 ng/ml, and prednisone was tapered to not more than 10 mg/day by 3 months after transplantation. All patients received induction therapy with either daclizumab or basiliximab as per the product package insert.

In addition, prophylactic antimicrobials were standardized among the participating sites. All patients with either donor and/or recipient cytomegalovirus (CMV)-positive serostatus received either intravenous ganciclovir or oral valganciclovir for a total of 90 days. Lung transplant recipients who were negative for both donor and recipient CMV serostatus received valacyclovir for 90 days. Antifungal prophylaxis was determined by each site. Pneumocystis jiroveci prophylaxis was continued throughout the study. Lipid-lowering medications were recommended according to the National Cholesterol Education Program guidelines.

What is being measured

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

  1. Acute Rejection Rate at 12 Months

    Raw proportion of patients that experienced acute rejection at or before 12 months.

    Measured: 12mos

Secondary outcomes (7)
  1. Acute Rejection-free Survival at 12 Months

    Kaplan-Meier estimate of proportion of patients that had not experienced acute rejection by 12 months. Acute rejection is defined as rejection at any of the following grades.

    Grade A0 - None With/Without Grade A1 - Minimal Grade A2 - Mild Grade A3 - Moderate

    Measured: 12 mos

  2. Severity of Acute Rejection at 12 Months

    Raw proportion of patients that experienced rejection at or above grade A2 by 12 months.

    Grade A0 - None With/Without Grade A1 - Minimal Grade A2 - Mild Grade A3 - Moderate

    Measured: 12 mos

  3. Bronchiolitis Obliterans Syndrome (BOS) at 24 Months

    Kaplan-Meier estimate of proportion of patients that had not experienced BOS by 24 months.

    Measured: 24 mos

  4. Bronchiolitis Obliterans Syndrome (BOS) at 36 Months

    Kaplan-Meier estimate of proportion of patients that had not experienced BOS by 36 months.

    Measured: 36 mos

  5. Overall Survival at 12 Months

    Kaplan-Meier estimate of proportion of patients that survived to (i.e., had not died by) 12 months.

    Measured: 12 mos

  6. Overall Survival at 24 Months

    Kaplan-Meier estimate of proportion of patients that survived to (i.e., had not died by) 24 months.

    Measured: 24 mos

  7. Overall Survival at 36 Months

    Kaplan-Meier estimate of proportion of patients that survived to (i.e., had not died by) 36 months.

    Measured: 36 mos

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing azathioprine and sirolimus in people with Delayed Graft Function and Acute Graft Rejection, run by University of Chicago 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 3 inclusion and 7 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 21 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 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 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 4 Feb 2014). 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?

Acute Rejection Rate at 12 Months (time frame: 12mos). 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 NCT00321906, which also lists 2 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 21 Sep 2016.
