Study Endpoints
Primary Endpoints
Clinical Cure
14 days post-Baseline - Test-Of-Cure (TOC)

Percentage of participants with complete resolution of signs and symptoms (total VSS score of 0) with no additional antifungal therapy required. The vulvovaginal signs and symptom (VSS) scale ranges from 0 to 18, with higher scores being worse.

SCY-078 Breast Milk Concentrations.
Pre-dose up to 108 hours post first dose

To determine the levels of SCY-078 in breast milk in ng/mL, starting pre-dose (Baseline) on Day 1 until 108 hours post first dose. Concentrations of SCY-078 in milk is measured pre-dose, and in milk collected at the following post-dose intervals: 0-2 hours, 2-4 hours, 4-8 hours, 8-12 hours, 12-18 hours, 18-24 hours, 24-36 hours, 36-48 hours, 48-72 hours and 72-108 hours.

SCY-078 Plasma Concentrations.
Pre-dose up to 72-108 hours post first dose

To measure the levels of SCY-078 in plasma at pre-dose (0 hours), 2, 6, 8 12 hours post dose (prior to the second dose) and 24, 36, 48, 72 and 108 hours post first dose.
