Trial Outcomes & Findings for Moderate to Severe Plaque Psoriasis With Scalp Involvement (NCT NCT00791765)

NCT ID: NCT00791765

Last Updated: 2014-07-23

Results Overview

The Psoriasis Scalp Severity Index (PSSI) measures the extent of psoriasis involvement and the severity of erythema, infiltration, and desquamation of the scalp. Involvement and severity of psoriasis for the PSSI is scored by physicians using a scale from 0 to 72, where 0 = no psoriasis, and higher scores indicating more severe disease. The PSSI calculation does not include the face or neck area.

PRIMARY outcome

Timeframe: Baseline and Week 12

Population: Intention-to-Treat population (all patients who were randomized to investigational product) with available data; last observation carried forward (LOCF) imputation was used.

The Psoriasis Scalp Severity Index (PSSI) measures the extent of psoriasis involvement and the severity of erythema, infiltration, and desquamation of the scalp. Involvement and severity of psoriasis for the PSSI is scored by physicians using a scale from 0 to 72, where 0 = no psoriasis, and higher scores indicating more severe disease. The PSSI calculation does not include the face or neck area.

SECONDARY outcome

Timeframe: Baseline and Week 12

Population: Intention-to-Treat with available data; last observation carried forward (LOCF) imputation

Percentage of participants achieving at least a 75% improvement from baseline in the Psoriasis Scalp Severity Index (PSSI) at Week 12. The Psoriasis Scalp Severity Index (PSSI) measures the extent of psoriasis involvement and the severity of erythema, infiltration, and desquamation of the scalp. Involvement and severity of psoriasis for the PSSI is scored by physicians using a scale from 0 to 72, where 0 = no psoriasis, and higher scores indicating more severe disease. The PSSI calculation does not include the face or neck area. PSSI 75 indicates at least a 75% improvement in the PSSI score from baseline.

Timeframe: Baseline and Week 24

Population: Intention-to-Treat with available data; last observation carried forward (LOCF) imputation.

Percent change from baseline in Psoriasis Scalp Severity Index (PSSI) in participants switching from placebo to etanercept at Week 12 (Group B) at Week 24. The PSSI measures the extent of psoriasis involvement and the severity of erythema, infiltration, and desquamation of the scalp. Involvement and severity of psoriasis for the PSSI is scored by physicians using a scale from 0 to 72, where 0 = no psoriasis, and higher scores indicate more severe disease. The PSSI calculation does not include the face or neck area.

SECONDARY outcome

Timeframe: 12 Weeks

Population: Intention-to-Treat with available data at week 12; last observation carried forward (LOCF) imputation was used.

This response scale was adapted from the Medical Outcomes Study: Patient Satisfaction Survey. To assess satisfaction with treatment, the participant was asked to check a box (from "very dissatisfied" to "very satisfied") to indicate his or her level of satisfaction with the medication's control of psoriasis.
