Study Comparing Conversion to Sirolimus vs. Continued Use of Calcineurin Inhibitors in Kidney Transplant Recipients

April 22, 2010 updated by: Wyeth is now a wholly owned subsidiary of Pfizer

A Randomized, Open-label, Comparative Evaluation of Conversion From Calcineurin Inhibitors to Sirolimus Versus Continued Use of Calcineurin Inhibitors in Renal Allograft Recipients

The purpose of this study is to determine the effect of conversion from calcineurin inhibitor to sirolimus based therapy on renal function.

Description

Inclusion Criteria:

  • Age greater than or equal to 13 years.
  • Receiving CsA or tacrolimus from the time of transplantation or within 2 weeks thereafter
  • Patients with a functioning allograft and a Nankivell GFR greater than or equal to 20 mL/min, within 2 weeks before randomization

Exclusion Criteria:

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: A
Conversion from calcineurin inhibitor immunosuppression to Sirolimus-based immunosuppression
Drug: tacrolimus
Drug: Cyclosporine A
Drug: Sirolimus
Sirolimus, Cyclosporine A & Tacrolimus are concentration controlled

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Nankivell Glomerular Filtration Rate (GFR)
Time Frame: 52 weeks
Nankivell GFR: patients with baseline GFR of 20.0 to 40.0 mL/min and patients with baseline GFR of greater than 40.0 mL/min. GFR is an index of kidney function. A higher value means better kidney function.
52 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
First Occurrence of Biopsy-confirmed Acute Rejection, Graft Loss, or Death.
Time Frame: 52 and 104 weeks
Number of patients who experienced for the first time either biopsy-confirmed acute rejection, graft loss, or death by weeks 52 and 104. Assessed by individual endpoint and as composite endpoint (all combined).
52 and 104 weeks
