Trial Outcomes & Findings for Safety and Efficacy of ARQ-154 Foam in Adolescent and Adult Subjects With Scalp and Body Psoriasis (NCT NCT04128007)

NCT ID: NCT04128007

Last Updated: 2022-10-26

Results Overview

The number of participants achieving success in the S-IGA scale is presented for each arm. Success is defined as an S-IGA score of 0 ('clear') or 1 ('almost clear'), plus a 2-grade improvement from baseline.The S-IGA is 5-point scale assessing the severity of plaque psoriasis on the scalp, with scores ranging from 0 ('clear') to 4 ('severe'). Higher scores indicate greater symptom severity.

PRIMARY outcome

Timeframe: Week 8

Population: All randomized participants with S-IGA score at baseline ≥2 and data available are included.

The number of participants achieving success in the S-IGA scale is presented for each arm. Success is defined as an S-IGA score of 0 ('clear') or 1 ('almost clear'), plus a 2-grade improvement from baseline.The S-IGA is 5-point scale assessing the severity of plaque psoriasis on the scalp, with scores ranging from 0 ('clear') to 4 ('severe'). Higher scores indicate greater symptom severity.

Success is defined as a B-IGA score of 0 ('clear') or 1 ('almost clear'), plus a 2-grade improvement from baseline. The B-IGA is 5-point scale assessing the severity of plaque psoriasis on the body, with scores ranging from 0 ('clear') to 4 ('severe'). Higher scores indicate greater symptom severity.

SECONDARY outcome

Timeframe: Baseline and Weeks 2, 4, 8

Population: All randomized participants with baseline SI-NRS score ≥4 with data available are included.

The number of participants with a baseline SI-NRS score ≥4 who achieve success (a ≥4-point improvement from Baseline) at Weeks 2, 4, and 8 is presented for each arm. The SI-NRS is a participant-reported rating of severity of itch at its highest intensity during the previous 24-hour period. The scale ranges from 0 ('no itch') to 10 ('worst imaginable itch'), with higher scores indicating greater symptom severity. Results are based on observed data only.

SECONDARY outcome

Timeframe: Baseline and Weeks 4 and 8

Population: All randomized participants are included, with multiple imputation used for missing data.

The change from baseline in total PSD scores at Weeks 4 and 8 is presented for each arm. The PSD is a 16-item questionnaire asking subjects to rate the severity of psoriasis-related symptoms in the past 24 hours. Each question is scored from 0 ("no symptoms") to 10 ("worst imaginable symptoms"). Scores range from 0 to 160, with higher scores indicating greater symptom severity.

SECONDARY outcome

Timeframe: Up to 8 weeks

Population: All randomized participants are included.

The time to achieve PSSI-50 (i.e., a 50% reduction from baseline in PSSI score) is presented for each arm. The PSSI measures the extent of psoriasis involvement and the severity of erythema, induration, and desquamation of the scalp. Involvement and severity of psoriasis for the PSSI is scored using a scale of 0 to 72, where 0 = no psoriasis and higher scores indicating greater symptom severity. Results are based on observed data only.
