Brief Summary:
This study is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of oral ibrexafungerp (formerly "SCY-078") compared to placebo in female subjects 12 years and older with recurrent VVC (RVVC).

Condition or disease Intervention/treatment Phase
Recurrent Vulvovaginal Candidiasis Drug: Fluconazole Tablet Drug: IBREXAFUNGERP Drug: Placebo oral tablet Phase 3

Detailed Description:

This study is a Phase 3, multicenter, randomized, double-blind study to evaluate the efficacy and safety of oral ibrexafungerp (formerly "SCY-078") compared to placebo in female subjects 12 years and older with RVVC. The primary objective of the study is to evaluate the efficacy of oral ibrexafungerp in preventing recurrences of VVC in subjects with RVVC based on Clinical Success. Approximately 320 subjects are planned to be enrolled into the study. All subjects will receive treatment with oral fluconazole for their acute episode present at screening. Subjects who respond to fluconazole for their acute episode will be enrolled in the prevention of recurrence phase of the study and randomized to ibrexafungerp or placebo.

Subjects who fail treatment with fluconazole for their acute episode will be included in a nested open label Sub-Study, in which they will be offered one-day oral ibrexafungerp for their unresolved acute episode.
