Trial Outcomes & Findings for Treatment of Gardnerella Vaginalis Vaginal Colonization With Amoxicillin (NCT NCT03211156)

NCT ID: NCT03211156

Last Updated: 2020-08-28

Results Overview

Eradication of GV is defined by a negative NAAT result for GV at Visit 2. Participants who have a missing GV NAAT result at the test of cure (TOC) visit were classified as treatment failures. The denominator for proportions is based on the number of subjects who were randomized to the specified treatment group.

PRIMARY outcome

Timeframe: Day 15 to 21

Population: Participants included in the ITT population are those who randomized, regardless of whether they received study treatment or were compliant with the administration procedures or schedule.

Eradication of GV is defined by a negative NAAT result for GV at Visit 2. Participants who have a missing GV NAAT result at the test of cure (TOC) visit were classified as treatment failures. The denominator for proportions is based on the number of subjects who were randomized to the specified treatment group.

0.21 proportion of participants
Interval 0.12 to 0.34

SECONDARY outcome

Timeframe: Day 1 through Day 15 to 21

Population: Participants included in the safety population are those who randomized and received at least one dose of treatment.

AEs were defined as any untoward medical occurrence in a participant administered a pharmaceutical product. SAEs included any untoward medical occurrence that resulted in death; was life threatening; was a persistent/significant disability/incapacity; required inpatient hospitalization or prolongation or a congenital anomaly/birth defect. AEs and SAEs were collected from participants following the first dose of treatment through Visit 2 (Day 15-21). Events are included if deemed by the investigator to be related to the study product.
