Evaluate Efficacy Study of Combination Therapy of Everolimus and Low Dose Tacrolimus in Renal Allograft Recipients

To evaluate prevention effect of combination therapy of Everolimus and low-dose Tacrolimus in comparison with standard-dose Tacrolimus therapy with Mycophenolic acid on the New Onset Diabetes Mellitus after transplantation in the renal allograft recipients

An open-label, randomized, multi-center, comparative parallel study to evaluate prevention effect of combination therapy of Everolimus and low-dose Tacrolimus in comparison with standard-dose Tacrolimus therapy with Mycophenolic acid on the New Onset Diabetes Mellitus after transplantation in the renal allograft recipients: PROTECT study
