Trial Outcomes & Findings for A Phase 2 Study of SYM-1219 to Treat Bacterial Vaginosis (NCT NCT02147899)

NCT ID: NCT02147899

Last Updated: 2020-11-13

Results Overview

Clinical Cure is a composite endpoint determined by normalization of the vaginal discharge and a negative KOH "Whiff" test and Clue cells less than 20% of the total epithelial cells on microscopic examination of the vaginal wet mount. (Number of subjects with clinical cure at TOC/EOS)
