A Study of Oral Oteseconazole (VT-1161) for the Treatment of Patients With Recurrent Vaginal Candidiasis (Yeast Infection) (VIOLET)

A Study of Oral Oteseconazole (VT-1161) for the Treatment of Patients With Recurrent Vaginal Candidiasis (Yeast Infection)

A Phase 3, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of Oteseconazole (VT-1161) Oral Capsules in the Treatment of Subjects With Recurrent Vulvovaginal Candidiasis

Recurrent vulvovaginal candidiasis (RVVC), also known as recurrent yeast infections, is defined as at least 3 episodes of acute VVC in the past 12 months. Several properties of oteseconazole (VT-1161) suggest that it might be a safer and more effective treatment for RVVC than other oral antifungal medicines. This study will evaluate the effectiveness and safety of oteseconazole (VT-1161) for the treatment of RVVC and consists of 2 parts. The first part of the study is a 2-week period for the treatment of the patient's current VVC episode with 3 150mg doses of fluconazole. The 2nd part consists of 12 weeks, when the patient will take either oteseconazole (VT-1161) 150 mg or a placebo (according to a random assignment), and then a 36-week follow-up period. In addition, at participating sites, an amendment to the study allows US patients who complete the initial 48 weeks without experiencing a confirmed RVVC episode to continue in a 48-week observational extension period designed to evaluate the continued effectiveness of oteseconazole (VT-1161). This study is identical to VMT-VT-1161-CL-011.

Percentage of Subjects With 1 or More Culture-verified Acute VVC Episodes During the Maintenance Phase of the Study in the Intent-to-treat (ITT) Population.

The primary efficacy outcome measure was the percentage of subjects with 1 or more culture-verified acute VVC episodes during the maintenance phase (post-randomization through Week 48) in the intent-to-treat population. An acute VVC episode during the maintenance phase (considered a recurrent episode) was defined as a positive fungal culture for Candida species and a clinical signs and symptoms score of ≥3. To calculate the signs and symptoms score, each vulvovaginal sign (erythema, edema, excoriation) and symptom (itching, burning, irritation) was scored using the following scale, with a higher score indicating a worse outcome. 0 = none (complete absence of any sign or symptom), 1 = mild (slight), 2 = moderate (definitely present), 3 = severe (marked, intense)
