Dose-Finding Study of Oral Ibrexafungep (SCY-078) vs. Oral Fluconazole in Subjects With Acute Vulvovaginal Candidiasis


This is a multicenter, randomized, double-blind, double-dummy, active-controlled, dose-finding study to compare the efficacy, safety and tolerability of oral SCY-078 versus oral fluconazole in adult female subjects 18 years and older with moderate to severe Acute Vulvovaginal Candidiasis (AVVC). Approximately 180 eligible subjects (30 subjects per treatment group) will be enrolled and randomized into the study.

Detailed Description

This is a Phase 2, multicenter, randomized, double-blind, double-dummy, active-controlled, dose-ranging study of female subjects with moderate to severe Acute Vulvovaginal Candidiasis. Subjects will be randomized to either the investigational arm (SCY-078) with 5 different dose regiments ranging from 1 to 3 days of treatment or to the active-control arm (fluconazole) for 1 day of treatment. After randomization subjects may be seen on study Day 3 (on site visit for PK subjects) , Day 10 (±2,) and Day 25 (+4).

Clinical Trial Outcome Measures

Primary Measures

  • Clinical Cure (Complete Resolution of Signs and Symptoms)
    • Time Frame: 8-12 days
    • Measured by the percentage of subjects with clinical cure (complete resolution of signs and symptoms) at the test-of-cure (TOC) visit

Secondary Measures

  • Co-occurrence of Clinical and Mycological Cure
    • Time Frame: 29 days
    • The percentage of subjects with both clinical cure and mycological eradication (negative fungal culture) the Test-of cure.
