Clinical Trial Summary

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


Clinical Trial 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. ;
