Safety and Efficacy of Oral Ibrexafungerp (SCY-078) vs. Oral Fluconazole in Subjects With Vulvovaginal Candidiasis

Phase 2

Completed

• Conditions: Vulvovaginal Candidiasis
• Interventions: Drug: SCY-078; Drug: Fluconazole

• Registration Number: NCT02679456
• Lead Sponsor: Scynexis, Inc.

Brief Summary

This is a randomized, multicenter, evaluator blinded study to evaluate the safety, tolerability, efficacy and pharmacokinetics of SCY-078 compared to Fluconazole in adult patients with moderate to severe Vulvovaginal Candidiasis (VVC) and a history of frequent episodes of VVC. Approximately 90 subjects, meeting the inclusion criteria will be enrolled and randomized in a 1:1:1 ratio to one of the 3 treatment arms: Oral SCY-078 in 2 dose regimens or oral Fluconazole. After enrollment, subjects will be evaluated on Day-5 (end of treatment visit), Day-24 (test of cure visit), Day-60, Day 90 and Day 120 (end of observation period visit) or at any time that a recurrence or clinical failure is suspected, up to the end of observation period.

Detailed Description

This is a randomized, multicenter, evaluator blinded study to evaluate the safety, tolerability, efficacy and pharmacokinetics of SCY-078 compared to Fluconazole in adult patients, from 18 to 65 years of age, with moderate to severe Vulvovaginal Candidiasis (VVC) and a history of frequent episodes of VVC. Approximately 90 subjects, meeting the inclusion criteria will be enrolled and randomized in a 1:1:1 ratio to one of the 3 treatment arms: oral SCY-078 does regimen 1, or oral SCY-078 does regimen 2, or oral Fluconazole. After enrollment, subjects will be evaluated on Day-5 (end of treatment visit), Day-24 (test of cure visit), Day-60, Day 90 and Day 120 (end of observation period visit) or at any time that a recurrence or clinical failure is suspected, up to the end of observation period.

Primary Objectives:

\* To evaluate the safety and efficacy of 2 dosing regimens of Oral SCY-078 in subjects with moderate to severe Vulvovaginal Candidiasis (VVC)

Secondary Objectives:

\* To estimate the effect of Oral SCY-078 therapy in the rate and time to recurrence in subjects with a history of frequent episodes of VVC
