Trial Outcomes & Findings for Safety and Efficacy Study of A Novel Ointment to Treat Plaque Type Psoriasis (NCT NCT00759161)

NCT ID: NCT00759161

Last Updated: 2017-03-06

Results Overview

OTPSS is a scale to assess plaque severity. Each target plaque was scored on a severity rating scale ranging from 0 (no plaque) to 8 (very severe plaque), where higher score indicated more severity of a plaque. In this outcome measure, percentage of participants with reduced OTPSS at Day 28 were reported and comparison of ointment and vehicle treated plaque was given as 'Ointment treated plaque versus (vs.) vehicle treated plaque' and 'Vehicle treated plaque vs. ointment treated plaque'.
