Further study details as provided by National Taiwan University Hospital:

Primary Outcome Measures:
  • Pharmacokinetics of sirolimus in different regimens
  • Dose-concentration relationship of sirolimus

Secondary Outcome Measures:
  • Efficacy of rejection prevention
  • Dosage regimen of sirolimus + cyclosporine or tacrolimus
  • Dose-concentration relationship of cyclosporine/tacrolimus

Estimated Enrollment: 40
Study Start Date: March 2002
Estimated Study Completion Date: June 2003
Detailed Description:

The dose and pharmacokinetic of an immunosuppressant may differ in different ethnics, and different combinations.

The purpose of this study is to determine the dose-level relationship of sirolimus through pharmacokinetic study. The dose-level relationship of cyclosporine and tacrolimus was also assessed. From clinical outcome and blood level of sirolimus and cyclosporine or tacrolimus, we can design the most appropriate cyclosporine/sirolimus/steroid or tacrolimus/sirolimus/steroid dose regimen for Taiwanese.
