Abstract

<abstract abstract-type="main" id="tri12437-abs-0001"> <title>Summary</title> <p>In a 36‐month, open‐label, multicenter trial, 202 kidney transplant recipients were randomized at week 7 post‐transplant to convert to everolimus or remain on cyclosporine: 182 were analyzed to month 36 (92 everolimus, 90 controls). Mean (SD) change in measured GFR (mGFR) from randomization to month 36 was 1.3 (14.0) ml/min with everolimus versus −1.7 (15.4) ml/min in controls (<italic>P</italic> = 0.210). In patients who remained on treatment, mean mGFR improved from randomization to month 36 by 7.9 (11.5) ml/min with everolimus (<italic>n</italic> = 37) but decreased by 1.4 (14.7) ml/min in controls (<italic>n</italic> = 62) (<italic>P</italic> = 0.001). During months 12–36, death‐censored graft survival was 100%, patient survival was 98.9% and 96.7% in the everolimus and control groups, respectively, and 13.0% and 11.1% of everolimus and control patients, respectively, experienced mild biopsy‐proven acute rejection (BPAR). Protocol biopsies in a limited number of on‐treatment patients showed similar interstitial fibrosis progression. Donor‐specific antibodies were present at month 36 in 6.3% (2/32) and 18.0% (9/50) of on‐treatment everolimus and control patients with available data (<italic>P</italic> = 0.281). During months 12‐36, adverse events were comparable, but discontinuation was more frequent with everolimus (33.7% vs. 10.0%). Conversion from cyclosporine to everolimus at 7 weeks post‐transplant was associated with a significant benefit in renal function at 3 years when everolimus was continued.</p> </abstract>
