Abstract BACKGROUND: Pharmacokinetic modeling supports trough monitoring of everolimus, but prospective data comparing this approach versus mycophenolate mofetil (MMF) in de novo cardiac transplant recipients are currently unavailable. METHODS: In a 12-month multicenter open-label study, cardiac transplant patients received everolimus (trough level 3-8 ng/mL) with reduced cyclosporine A (CsA) or MMF (3 g/day) with standard CsA, both with corticosteroids+/-induction therapy. RESULTS: In total, 176 patients were randomized (everolimus 92, MMF 84). Mean creatinine clearance was 72.5+/-27.9 and 76.8+/-32.1 mL/min at baseline, 65.4+/-24.7 and 72.2+/-26.2 mL/min at month 6, and 68.7+/-27.7 and 71.8+/-29.8 mL/min at month 12 with everolimus and MMF, respectively. The primary endpoint was not met since calculated CrCl at month 6 posttransplant was 6.9 mL/min lower with everolimus, exceeding the predefined margin of 6 mL/min. However, by month 12 the between-group difference had narrowed versus baseline (3.1 mL/min). All efficacy endpoints were noninferior for everolimus versus MMF. The 12-month incidence of biopsy-proven acute rejection International Heart and Lung Transplantation grade more than or equal to 3A was 21 of 92 (22.8\%) with everolimus and 25 of 84 (29.8\%) with MMF. Adverse events were consistent with class effects including less-frequent cytomegalovirus infection with everolimus (4 [4.4\%]) than MMF (14 [16.9\%], P=0.01). CONCLUSION: Concentration-controlled everolimus with reduced CsA results in similar renal function and equivalent efficacy compared with MMF with standard CsA at 12 months after cardiac transplantation.
