Summary
The proliferation signal inhibitor everolimus (Certican), has demonstrated efficacy with full‐dose cyclosporine (CsA) (Neoral®). Two multicenter randomized controlled studies were performed to compare 12‐month efficacy and safety of everolimus 1.5 and 3.0 mg/day with reduced‐dose CsA. Study 1 enrolled 237 de novo renal allograft recipients, randomizing 222 nonblack patients to either everolimus 1.5 or 3.0 mg/day, with the Neoral® dose guided by C2 (monitoring of CsA concentration 2 h after dosing). Study 2 had a similar protocol, with basiliximab included, enrolling 256 recipients and randomizing 243 nonblack patients. In Study 1, there was a lower incidence of acute rejection in nonblack patients on 3 mg/day (16.4%) compared with 1.5 mg/day (25.9%), P = 0.08. In Study 2, the inclusion of basiliximab lowered the overall incidence of acute rejection; 14.3% of nonblack patients (3 mg/day) and 13.6% of nonblack patients (1.5 mg/day) had acute rejection by 12 months (P =0.891). Renal function was preserved throughout the study, with no differences observed between groups within studies. Everolimus was well tolerated with no significant differences between doses. Everolimus, in combination with reduced‐dose Neoral®, demonstrated efficacy and was well tolerated. Basiliximab allows for utilization of lower doses of everolimus with reduced dosing of Neoral®.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
