BAL4815 is a new antifungal agent, which belongs to the azoles. BAL4815 is administered as the water-soluble prodrug BAL8557 (figure 1). In vitro, BAL4815 showed broadspectrum antifungal activity against Candida spp. (including fluconazole-resistant C. albicans ), Cryptococcus spp., and various filamentous fungi including fluconazole-resistant strains. Monte Carlo Simulations (MCS) is a technique that can be used to determine the Probability of Target Attainment (PTA) for pharmacodynamic indices (PDI). Results from a single dose pharmacokinetic study were used to determine PTAs and, based on levels of BAL4815 evaluate the potential use of BAL8557 to treat fungalb infections
