NCT ID: NCT02831998
Last Updated: 2023-02-08
Results Overview

Participant Flow
Enrollment consists of subjects that advanced from screening to randomization and treatment. Each subject had 2 test products applied bilaterally; therefore, the numbers will not add up uniformly across arms due to the pre-determined cohort/block design. Result totals will be less than than the treated number as the per subject/area/intervention anatomical site must have an acceptable baseline count/flora.
Unit of analysis: Ab or groin

Treated Population
n=440 Participants
Each subject could have received 2 out of 3 test products randomly assigned. Demographics were not stratified by test product due to study design. While 440 was the treated population, to be evaluable for efficacy, each subject anatomical sample site (4/per subject) would need to pass the minimum log10 baseline requirements.

PRIMARY outcome
Timeframe: 10 minutes post product applicationPopulation: Treated subjects with a treatment day baseline criteria of 5.0-7.5 log10 CFU/cm\^2 recoveries for each sampling site (2 groin sampling sites per subject).
A 3-log10 CFU/cm\^2 bacterial reduction on the inguinal region is considered a success.
