Abstract

The feasibility of de novo everolimus without calcineurin inhibitor (CNI) therapy following liver transplantation was assessed in a multicenter, prospective, open-label trial. Liver transplant patients were randomized at 4 weeks to start everolimus and discontinue CNI, or continue their current CNI-based regimen. The primary endpoint was adjusted estimated GFR (eGFR; Cockcroft-Gault) at month 11 postrandomization. A 24-month extension phase followed 81/114 (71.1%) of eligible patients to month 35 postrandomization. The adjusted mean eGFR benefit from randomization to month 35 was 10.1mL/min (95% confidence interval [CI] -1.3, 21.5mL/min, p=0.082) in favor of CNI-free versus CNI using Cockcroft-Gault, 9.4mL/min/1.73m(2) (95% CI -0.4, 18.9, p=0.053) with Modification of Diet in Renal Disease (four-variable) and 9.5mL/min/1.73m(2) (95% CI -1.1, 17.9, p=0.028) using Nankivell. The difference in favor of the CNI-free regimen increased gradually over time due to a small progressive decline in eGFR in the CNI cohort despite a reduction in CNI exposure. Biopsy-proven acute rejection, graft loss and death were similar between groups. Adverse events led to study drug discontinuation in five CNI-free patients and five CNI patients (12.2% vs. 12.5%, p=1.000) during the extension phase. Everolimus-based CNI-free immunosuppression is feasible following liver transplantation and patients benefit from sustained preservation of renal function versus patients on CNI for at least 3 years. The beneficial effect on renal function achieved by early CNI withdrawal and treatment with everolimus after liver transplantation is still evident after three years.
