Vaginal Ovule With Flavonoid Tea Extract for the Correction of Imbalance in the Vaginal Environment

The objective was to determine whether vaginal ovule with tea extract once-daily for 5-7 days improves symptoms of intermediate vaginal flora and prevents the development of bacterial vaginosis. Composite primary endpoint designed as a drop in the Nugent score, vaginal pH, or improvement of subjective symptoms was compared between the active and vehicle (polyethylene-glycol) arm after 7 days of application and following 7 days after the application. Secondary outcome measures were (1) Correction of the vaginal environment (as previously defined) 7 days after the completion of the prescribed 7-day regimen (day 14); (2) change in each parameter separately; (3) change in individual subjective symptoms, (4) exploratory analysis of the microbial environment at each subject visit. The study was approved and supervised by the National authority and Ethics committee and prospectively registered in the Czech national medical device trial registry RZPRO and the European medical device trial registry EUDAMED.
