Trial Outcomes & Findings for Safety and Efficacy of IDP-122 in the Treatment of Participants With Plaque Psoriasis (NCT NCT02515097)

NCT ID: NCT02515097

Last Updated: 2020-01-27

Results Overview

Treatment success defined as at least a 2-grade improvement from Baseline in the IGA score and an IGA score equating to "clear" or "almost clear" at Week 8. The IGA score was based on a 5-point scale ranging from 0 to 4 (0=clear, 1=almost clear, 2=mild, 3=moderate, and 4=severe). The face, scalp, palms, soles, axillae, and intertriginous areas were excluded from this assessment.

PRIMARY outcome

Timeframe: Week 8

Population: Participants who were randomized and dispensed study drug (ITT population). Markov Chain Monte Carlo (MCMC) multiple imputation was used to impute missing data.

Treatment success defined as at least a 2-grade improvement from Baseline in the IGA score and an IGA score equating to "clear" or "almost clear" at Week 8. The IGA score was based on a 5-point scale ranging from 0 to 4 (0=clear, 1=almost clear, 2=mild, 3=moderate, and 4=severe). The face, scalp, palms, soles, axillae, and intertriginous areas were excluded from this assessment.
