Trial Outcomes & Findings for A Study of A-101 Solution in Subjects With Common Warts. (NCT NCT02669862)

NCT ID: NCT02669862

Last Updated: 2018-12-07

Results Overview

The primary effectiveness will consist of the mean change from Visit 2 to Visit 10 in Physician Wart Assessment (PWA) performed using Analysis of Covariance (ANCOVA) with Visit 2 PWA as the covariate. Physician Wart Analysis is a measurement scale from 0 to 3 that evaluates the wart with 0 being clear and 3 being clinically diagnosable wart that is raised, with an obviously rough surface.

PRIMARY outcome

Timeframe: 57 Days

Population: Number of participants analyzed is the number of participants completing the protocol through visit 10.

The primary effectiveness will consist of the mean change from Visit 2 to Visit 10 in Physician Wart Assessment (PWA) performed using Analysis of Covariance (ANCOVA) with Visit 2 PWA as the covariate. Physician Wart Analysis is a measurement scale from 0 to 3 that evaluates the wart with 0 being clear and 3 being clinically diagnosable wart that is raised, with an obviously rough surface.

SECONDARY outcome

Timeframe: visit 10 to visit 13

Population: Only the number of participants clear at visit 10 are compared to the number of participants clear at visit 13 to get the percentage clear for active treatment groups only.

Percentage of subjects whose target wart was clear at Visit 10 and who remained clear at Visit 13 for active treatment groups
