Subjects who meet all of the inclusion and none of the exclusion criteria will be enrolled into the study and will be randomized in a 2:1 ratio to either oral ibrexafungerp or ibrexafungerp matching placebo, as follows:
* Oral ibrexafungerp 300-mg dose BID for 1 day
* Oral ibrexafungerp matching placebo BID for 1 day
Subjects will receive their first dose of study drug at the site and will be dispensed the second dose for self-administration at home 12 hours after the first dose. Study Blinding, Randomization and Stratification: This is a randomized, double-blind study.
All site and sponsor personnel will be blinded to treatment assignment. Approximately 366 eligible subjects will be enrolled and randomized in a 2:1 ratio to one of the two study treatment groups. For the purpose of maintaining treatment blinding, all subjects randomized to the placebo group will receive matching ibrexafungerp placebo tablets.
