Abstract

Objective: We analyzed the efficacy and safety of an everolimus with reduced-exposure calcineurin inhibitor (EVR+rCNI) versus mycophenolic acid with standard-exposure CNI (MPA+sCNI) regimen in Asian patients from the TRANSFORM study. Methods: In this 24-month, open-label study, de novo kidney transplant recipients (KTxRs) were randomized (1:1) to receive EVR+rCNI or MPA+sCNI, along with induction therapy and corticosteroids. Results: Of the 2037 patients randomized in the TRANSFORM study, 293 were Asian (EVR+rCNI, N = 136; MPA+sCNI, N = 157). At month 24, EVR+rCNI was noninferior to MPA+sCNI for the binary endpoint of estimated glomerular filtration rate (eGFR) < 50 ml/min/1.73 m2 or treated biopsy-proven acute rejection (27.0% vs. 29.2%, P =.011 for a noninferiority margin of 10%). Graft loss and death were reported for one patient each in both arms. Mean eGFR was higher in EVR+rCNI versus MPA+sCNI (72.2 vs. 66.3 ml/min/1.73 m2, P =.0414) even after adjusting for donor type and donor age (64.3 vs. 59.3 ml/min/1.73 m2, P =.0582). Overall incidence of adverse events was comparable. BK virus (4.4% vs. 12.1%) and cytomegalovirus (4.4% vs. 13.4%) infections were significantly lower in the EVR+rCNI arm. Conclusion: This subgroup analysis in Asian de novo KTxRs demonstrated that the EVR+rCNI versus MPA+sCNI regimen provides comparable antirejection efficacy, better renal function, and reduced viral infections (NCT01950819).
