  Purpose

The study hypotheses to be tested in this study are:

  • Conversion to everolimus at 3 months post-transplantation is safe and effective;
  • Accurate noninvasive molecular diagnostic tests can replace biopsy at 3 months pre-conversion (for the diagnosis of subclinical cellular and/or humoral rejection, tissue fibrosis and calcineurin inhibitor-induced nephrotoxicity) in kidney transplant recipients;
  • Follow-up biopsy at 12 months post-conversion (for the diagnosis of tissue fibrosis) can be replaced with accurate noninvasive molecular diagnostic tests in kidney transplant recipients.

Further study details as provided by Hospital de Clinicas de Porto Alegre:

Primary Outcome Measures:
  • Evaluate cumulative patient and graft survival at 12 months post conversion [ Time Frame: one year ] [ Designated as safety issue: No ]
    Patient and graft survival will be evaluated one year after randomization by Kaplan-Meier analysis


Secondary Outcome Measures:
  • Evaluation of estimated glomerular filtration rate 12 months post-conversion [ Time Frame: one year ] [ Designated as safety issue: No ]
    - To assess the efficacy of conversion from tacrolimus to everolimus 12 months post-conversion by measuring the estimated glomerular filtration rate using the Modification of Diet in Renal Disease (MDRD) equation


Estimated Enrollment: 120
Study Start Date: February 2012
Estimated Study Completion Date: July 2014
Estimated Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Tacrolimus

The subjects included in the study will be clinically followed up for at least 12 months. The patients will be selected at 3 months post-transplant according to inclusion and exclusion criteria and randomized in a 1:1 ratio for conversion to everolimus or maintenance of tacrolimus therapy.

Intervention arm: Tacrolimus

Drug: Tacrolimus
TACROLIMUS (C0 = 5-10 ng/mL) + MPS 1440 mg + Pred
Active Comparator: Everolimus

The subjects included in the study will be clinically followed up for at least 12 months. The patients will be selected at 3 months post-transplant according to inclusion and exclusion criteria and randomized in a 1:1 ratio for conversion to everolimus or maintenance of tacrolimus therapy.

Intervention arm: Everolimus

Drug: Everolimus
Everolimus (C0 = 6-10 ng/mL) + MPS 1440 mg + Pred

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both

  • Active infection at randomization;
  • Chronic liver disease;
  • Refusal to participate in the study;
  • Contraindications to kidney biopsy;
  • Biopsy findings at 3 months post-transplant including borderline rejection, cellular rejection or antibody-mediated rejection.
