A Multicenter, Randomized, Open-Label Study to Compare Micafungin with Fluconazole in the Prophylaxis of Invasive Fungal Infections in Living-Donor Liver Transplant Recipients.

BACKGROUND: Although invasive fungal infections (IFIs) contribute to substantial morbidity and mortality in liver transplant recipients, only a few randomized studies analyzed the results of antifungal prophylaxis with echinocandins. The aim of this open-label, non-inferiority study was to evaluate the efficacy and safety of micafungin in the prophylaxis of IFIs in living-donor liver transplantation recipients (LDLTRs), with fluconazole as the comparator.
METHODS: LDLTRs (N = 172) from five centers were randomized 1:1 to receive intravenous micafungin 100 mg/day or fluconazole 100~200 mg/day (intravenous or oral). A non-inferiority of micafungin was tested against fluconazole.
RESULTS: The per-protocol set included 144 patients without major clinical trial protocol violations: 69 from the micafungin group and 75 from the fluconazole group. Mean age of the study patients was 54.2 years and mean model for end-stage liver disease (MELD) score amounted to 16.5. Clinical success rates in the micafungin and fluconazole groups were 95.65% and 96.10%, respectively (difference: - 0.45%; 90% confidence interval [CI]: - 6.93%, 5.59%), which demonstrated micafungin's non-inferiority (the lower bound for the 90% CI exceeded - 10%). The study groups did not differ significantly in terms of the secondary efficacy endpoints: absence of IFIs at the end of the prophylaxis and the end of the study, time to proven IFI, fungal-free survival, and adverse reactions. A total of 17 drug-related adverse events were observed in both groups; none of them was serious and all resolved.
CONCLUSION: Micafungin can be used as an alternative to fluconazole in the prevention of IFIs in LDLTRs. CLINICAL TRIALS REGISTRATION: NCT01974375.
