Introduction. The half-life of everolimus is approximately 28 hours, but everolimus is generally administered twice a day. The aim of this prospective, single-center, exploratory study was to compare the efficacy and safety of a once a day everolimus (OD) with the standard twice a day administration regimen (BID) as immunosuppressive therapy in renal transplantation. Methods. Forty-one de novo renal transplant recipients prospectively assigned to OD (n = 21) or BID (n = 20) treatment were followed for 1 year. In the OD group, everolimus was orally administered targeting a trough blood level of 2 to 5 ng/mL. In the BID group, everolimus was given twice a day targeting a trough blood level of 3 to 12 ng/mL. All patients also received induction with basiliximab and low-dose calcineurin inhibitor immunosuppression. Results. At 1 year follow-up patient and graft survivals were 100%. The intention-to-treat analysis showed similar renal function between the two regimens: serum creatinine values for OD 1.54 +/- 0.6 versus BID 1.48 +/- 0.53 mg/dL (P = NS). Also the occurrence of acute rejection episodes was not significantly different: 4.8% in the OD versus 15% in the BID group, (P = NS). The median trough blood levels were significantly lower among the OD group: OD 4.5 versus BID 7.2 ng/mL (P < .001). Discussion. This study demonstrated that once a day administration of everolimus achieved excellent patient and graft survival and good renal function without an increased incidence of acute rejection episodes.
