Trial Outcomes & Findings for A Study to Evaluate and Compare the Efficacy and Pharmacokinetics of MK-0873 for the Treatment of Plaque Psoriasis (MK-0873-022) (NCT NCT01235728)

NCT ID: NCT01235728

Last Updated: 2019-02-08

Results Overview

Each lesion was evaluated for 3 components: erythema, induration, and scaling. Each component was given a score using the following scale: 0=none, 1=slight, 2=moderate, 3=marked, 4=very marked, with increasing score reflecting increased lesion severity. The TLS score (range 0 to 12) is calculated as the sum of the 3 components.

PRIMARY outcome

Timeframe: Baseline and Day 29

Population: The population consisted of all participants that received treatment, had no major protocol violations, and had TLS scores available at baseline and Day 29.

Each lesion was evaluated for 3 components: erythema, induration, and scaling. Each component was given a score using the following scale: 0=none, 1=slight, 2=moderate, 3=marked, 4=very marked, with increasing score reflecting increased lesion severity. The TLS score (range 0 to 12) is calculated as the sum of the 3 components.

Population: The population consisted of all participants that received treatment, had no major protocol violations, and had MK-0873 plasma trough values available for the Day 8, 15, 22, and 28 treatment.

Plasma samples were collected at 12 hours post-dose on Days 8, 15, 22, and 28 to evaluate the mean maximum plasma concentration at trough of MK-0873.
