Официальное название

A Multicenter, Randomized, Double-blind, Positive-controlled Phase II Clinical Study to Evaluate the Efficacy and Safety of WXSH0102 Tablets in the Treatment of Vulvovaginal Candidiasis (VVC)

Обзор

This study is a multicenter, randomized, double-blind, active-controlled, dose-ranging clinical trial designed to evaluate the efficacy and safety of the investigational drug compared to the active comparator in the treatment of vulvovaginal candidiasis. The trial consists of three phases: screening/enrollment (D-3 to D-1), treatment period (D1 to D3), and follow-up period (D4, D11±2, D25±3). Eligible subjects in this study will be randomized in a 1:1:1:1 ratio to three investigational drug arms with different dosing regimens and one active control arm. Specifically, Group A will receive WXSH0102 tablets with 1400 mg on the first day followed by a maintenance dose of 700 mg for two consecutive days, Group B will receive WXSH0102 tablets with 1000 mg on the first day followed by a maintenance dose of 500 mg for two consecutive days, Group C will receive WXSH0102 tablets with 600 mg on the first day followed by a maintenance dose of 300 mg for two consecutive days, and Group D (active control group) will receive fluconazole capsules for only one day on D1. All medications will be administered orally.
