Arms Assigned Interventions
Active Comparator: routine dose tacrolimus and myfortic Drug: routine dose tacrolimus and myfortic
oral regular dose of tacrolimus + usual dose of myfortic trough level of tacrolimus will be 2-5 pg/mL and oral myfortic dose will be 360mg b.i.d.
Other Name: optimum
Experimental: low dose tacrolimus and myfortic Drug: low dose tacrolimus and myfortic
low dose of tacrolimus + maximum dose of myfortic target trough level of tacrolimus should be reduced to 2-4 pg/mL for 3 months after randomization and oral MPS dose increased to 720mg b.i.d.
