*Purpose: The HEPHAISTOS study was designed to compare efficacy and safety of earlyuse of everolimus [EVR] combined with reduced tacrolimus [rTAC] versus Standard tacrolimus [TAC-C) in de novo liver transplant [LTx] recipients and to demonstrateimpact of CNI minimization on renal function.

*Methods: In this 12 months [M] prospective, open-label, randomized study with 15 German sites, 333 patients [pts] were randomized 1:1 between day 7 to 21 after LTx to either EVR(3-8ng/ml) + rTAC (&it5ng/ml), or TAC-C(6-10ng/ml), all with steroids until M6. Here we report M12 outcomes on renal function from full analysis [FAS] and per protocol [PP] set.

*Results: FAS consisted of 169 pts in the EVR+rTAC and 164 TAC-C group. Mean TAC trough concentration in the EVR+rTAC group exceeded target range until month 3 and remained close to the upper limit of the target range thereafter. Efficacy at M12 was similar with EVR+rTAC or TAC-C. Mean eGFR (MDRD4) was numerically higher with EVR+rTAC to M12 (adjusted mean difference of 4.09 mL/min/1.73m²;p=0.0970; FAS). Among patients in the PP (110 EVR+rTAC, 101 TAC-C), eGFR was significantly higher in favor of EVR+rTAC (+7.79 mL/min/1.73m²;p=0.0085) vs. TAC-C without compromising efficacy.

*Conclusions: Use of EVR with rTAC as early as 15 days post-LTx allowed for better renal function sustained for 12M compared to TAC-C. Hephaistos confirms that an early reduction of TAC post LTx offers renal benefits.
