 first line recommended therapy in most invasive candidiasis settings. Because the echinocandins can be administered only intravenously, orally administered azoles are often used as step-down agents after initial IV echinocandin therapy. However, antifungal treatment duration for invasive candidiasis typically extends for several weeks and patients for whom the azoles are not a suitable therapy due to resistance, intolerance, or risk of drug-to-drug interaction are restricted to use IV therapy for several weeks. Amphotericin B is also only available via IV administration and is associated with a significant risk of renal toxicity and infusion reactions, making it an unsuitable option in settings where there is underlying, or high risk of, renal impairment. Due to significant monitoring issues, Amphotericin B is also less desirable for outpatient parenteral administration. The echinocandins are typically well tolerated but clinical resistance is rising in many centers, due to development of mutations in the fks genes leading to echinocandin resistance and shift species with natural resistance as well as the rise of novel drug resistant species, such as Candida auris. When resistance develops, the available treatment options may be less efficacious or more toxic. The phenomenon of multi-drug resistance is also reported among isolates of different species of Candida, making the management of patients suffering from these infections extraordinarily challenging, considering the very limited treatment options available. Specifically, 90% of Candida auris isolates have been reported to be resistant to at least one antifungal agent and 30% of isolates resistant to at least two antifungals.

There is a clear need for new antifungal treatment options for patients with IC that are refractory or intolerant to available therapies as well as for those who would benefit from oral therapy. We believe ibrexafungerp has the potential to address many of these unmet needs by providing a well-tolerated oral antifungal agent, with low risk for drug-drug interactions that has activity against azole-resistant and most echinocandin-resistant strains.

Invasive Aspergillosis

Current treatment guidelines for IA in the U.S. and in Europe recommend the use of azoles (itraconazole, voriconazole or isavuconazole) as the initial first-line therapy. However, patients face unsatisfactory clinical outcomes with mortality rates ranging from 30% to 80% (depending on the stage of infection and the host underlying disease) and long treatment durations.
