Study summary

Test bioequivalence of generic tacrolimus (Tacni), using original tacrolimus (Prograf) as comparator, in elderly (>60 yr) renal transplant recipients

Read the detailed description

12-hour pharmacokinetic investigations performed on each formulation in each patient at steady-state. Patients will be randomized with regards to which formulation to start with. 1-2 weeks between each PK investigation.

Study arms

  • Experimental
    Tacni

    Tacrolimus administered as generic formulation Tacni in accordance with standard protocol at the transplant center

    Drug: Tacrolimus

  • Active comparator
    Prograf

    Tacrolimus administered as Prograf in according to standard protocol at the transplant center

    Drug: Tacrolimus

Interventions

  • DrugTacrolimus

What researchers measure

Primary outcomes

  1. Bioequivalence

    Bioequivalence will be assessed at steady-state by comparing both AUC(0-12) and Cmax ratios for generic:original-ratios and applying the stricter 90-111% bioequivalence criteria. AUC(0-12) will be assessed by trapezoidal rule and Cmax will be the highest actually measured concentration.

    Time frame: 10 weeks

Secondary outcomes

  1. Population model validation

    Use these new patient data to verify previously developed population pharmacokinetic model for tacrolimus.

    Time frame: 10 weeks
