EXTEND Protocol for Transplanted Patient to Evaluate Kidney Function

McGill University Health Centre/Research Institute of the McGill University Health Centre50 enrolled

Overview

The long-term use of calcineurin inhibitors in the maintenance phase after kidney transplantation is associated with typical adverse effects, such as potential contribution to progressive impairment of renal function, hypertension, and metabolic abnormalities. This 15 month study with a safety follow up is undertaken to evaluate the potential benefit of an alternative treatment strategy to the chronic use of CNI. It will establish, through a comparative design, the superior protection of kidney function provided by chronic usage of basiliximab over tacrolimus early post-transplantation using EDC kidneys.

Outcomes

Primary Outcomes

To compare the annualised change in GFR (delta GFR) at three and twelve months after baseline.

Secondary Outcomes

To demonstrate that the efficacy of basiliximab compared to the efficacy of tacrolimus kis comparable in the prevention of acute cellular rejection at 3 and 12 months after baseline.
