Trial Outcomes & Findings for The Safety, Efficacy and Pharmacokinetics of ARQ-151 Cream in Subjects With Chronic Plaque Psoriasis (NCT NCT03638258)

NCT ID: NCT03638258

Last Updated: 2022-09-02

Results Overview

The percentage of participants with an IGA score of 0 ('clear') or 1 ('almost clear') at Week 6 is reported. The IGA is 5-point scale assessing the severity of plaque psoriasis, with scores ranging from 0 ('clear') to 4 ('severe'), with higher scores indicating greater plaque severity.

The percentage of participants with an IGA score of 0 ('clear') or 1 ('almost clear') is reported. The IGA is 5-point scale assessing the severity of plaque psoriasis, with scores ranging from 0 ('clear') to 4 ('severe'), with higher scores indicating greater plaque severity.

Timeframe: Baseline (Day 1) and Weeks 4, 6, 8, and 12

Population: All randomized participants are included. Missing data from subjects was handled with linear interpolation (subjects with assessments before and after the missing assessment) or LOCF (subjects with assessments only before the missing assessment).

The percent change from baseline in mPASI score is presented. The mPASI combines the assessment of the severity of lesions and the area affected into a single score ranging from 0 ('no disease') to 72 ('maximal disease'), with higher scores indicating greater severity. For scoring, the body is divided into four sections (head \[h\]: 10% of a person's skin; arms \[a\] 20%; trunk \[t\] 30%; legs (l\] 40%); for each section, the percent of area involved is estimated from 0 (0% involved) to 6 (90 to 100% involved). Then, within each area, the severity is estimated by three clinical signs: erythema ('E'; redness), induration ('T'; thickness), and desquamation ('S'; scaling). Severity parameters are measured on a scale of 0 to 4, from none to maximum severity possible. Each of these areas is scored by itself, and then the four scores are combined into the final mPASI, using the formula mPASI = 0.1 (Eh + Th + Sh) Ah + 0.2 (Ea + Ta + Sa) Aa + 0.3 (Et + Tt + St) At + 0.4 (El + Tl + Sl) Al.

Population: All randomized participants are included. Missing data from subjects was handled with linear interpolation (subjects with assessments before and after the missing assessment) or LOCF (subjects with assessments only before the missing assessment).

The percentage of subjects achieving a 75% reduction in mPASI (eg, mPASI-75) score relative to baseline is presented. The mPASI combines the assessment of the severity of lesions and the area affected into a single score ranging from 0 ('no disease') to 72 ('maximal disease'), with higher scores indicating greater severity.

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 11 ("worst imaginable symptoms"). Scores range from 0 to 176, with higher scores indicating greater symptom severity. The mean (SD) change in PSD total score relative to baseline is presented for each treatment arm.

The DLQI is a 10-item scale asking subject to rate the severity of symptoms during the past week. Each item is scored from 0 ("not at all" or "not relevant") to 3 or 4 ("very much") \[2 questions are scored 0 to 3 and 8 questions are scored 0 to 4\]. The total DLQI score ranges from 0 to 48, with higher scores indicating greater symptom severity. The mean (SD) change from baseline DLQI score is presented.
