Efficacy and Safety of Low-Dose Cyclosporine with Everolimus and Steroids inde novoHeart Transplant Patients: A Multicentre, Randomized Trial

Abstract

A six-month, multicenter, randomized, open-label study was undertaken to determine whether renal function is improved using reduced-exposure cyclosporine (CsA) versus standard-exposure CsA in 199de novoheart transplant patients receiving everolimus and steroids ± induction therapy. Mean C2levels were at the low end of the target range in standard-exposure patients (n=100) and exceeded target range in reduced-exposure patients (n=99) throughout the study. Mean serum creatinine at Month 6 (the primary endpoint) was141.0±53.1 μmol/L in standard-exposure patients versus130.1±53.7 μmol/L in reduced-exposure patients (P=0.093). The incidence of biopsy-proven acute rejection ≥3A at Month 6 was 21.0% (21/100) in the standard-exposure group and 16.2% (16/99) in the reduced-exposure group (n.s.). Adverse events and infections were similar between treatment groups. Thus, everolimus with reduced-exposure CsA resulted in comparable efficacy compared to standard-exposure CsA. No renal function benefits were demonstrated; that is possibly related to poor adherence to reduced CsA exposure.
