Abstract: | We report 6-month results of renal allograft recipients enrolled in seven Australian centers as part of a worldwide, multicenter, randomized, open-label, concentration-controlled trial comparing standard tacrolimus (sTAC) with reduced tacrolimus (rTAC) both with sirolimus (SRL) and steroids. Patients were randomized 1:1 to either rTAC (n = 33) with a target maintenance concentration of SRL of 8 to 15 ng/mL and TAC of 3 to 7 ng/mL, or sTAC (n = 31) with SRL target of 5 to 10 ng/mL and TAC of 8 to 12 ng/mL. Antibody induction was prohibited. Adult recipients of a first or second cadaveric or non-HLA-identical living donor renal graft were eligible for enrollment. Recipients with a panel-reactive antibody level of >50% and recipients of regrafts who had lost their first graft from rejection within the first 6 months were ineligible. The groups were compared for graft function, incidence of rejection, and patient and graft survival at 6 months. There were no differences in demographics. There were 30% and 29% discontinuations in the rTAC and sTAC groups mainly due to adverse events in the first month. The 6-month patient and graft survival by intention-to-treat analysis was 94% and 91% for rTAC and 100% and 97% for sTAC (P = NS), respectively. Incidence and severity of biopsy-proven acute rejection was not different between the two groups, being 21% for rTAC and 19% for sTAC. The mean serum creatinine was 121 micromol/L and 148 micromol/L for rTAC and sTAC groups (P =.09), respectively. Glomerular filtration rate (GFR) was 68 mL/min and 62 mL/min (P =.23), respectively. Adverse events, infections, and antihypertensive and antilipidemic agent usage were similar. Of interest is that the overall incidence of thrombotic microangiopathy was 14%. These results support the safety and efficacy of SRL + TAC. Reduced TAC is associated with a trend toward improved renal function. |
