Pharmacodynamic Optimization for Treatment of Invasive Candida auris Infection.

is an emerging multidrug-resistant threat. The pharmacodynamics of three antifungal classes against nine strains was explored using a murine invasive candidiasis model. The total drug median pharmacodynamic (PD) target associated with net stasis was a fluconazole AUC/MIC (the area under the concentration-time curve over 24 h in the steady state divided by the MIC) of 26, an amphotericin B /MIC (maximum concentration of drug in serum divided by the MIC) of 0.9, and a micafungin AUC/MIC of 54. The micafungin PD targets for were ≥20-fold lower than those of other species in this animal model. Clinically relevant micafungin exposures produced the most killing among the three classes.
