Trial Outcomes & Findings for Efficacy and Safety of MEDI3506 in Adult Subjects With Atopic Dermatitis (NCT NCT04212169)

NCT ID: NCT04212169

Last Updated: 2023-09-28

Results Overview

The EASI evaluates 4 anatomic regions for severity and extent of key disease signs and focuses on the acute and chronic signs of inflammation (ie, erythema, edema, papulation, excoriation, and lichenification). The maximum score is 72, with higher values indicating more severe disease. Analysis was performed using mixed effect model for repeated measures and MCP-mod dose response model.

The IGA allows investigators to assess overall AD disease severity at 1 given time point and consists of a 5-point severity scale from clear to very severe disease (0 = clear, 1 = almost clear, 2 = mild disease, 3 = moderate disease, and 4 = severe disease).

The Dermatology Life Quality Index (DLQI) is a 10-item, patient- completed, health-related quality of life assessment of dermatology conditions with a recall period of 1 week. Each item is scored on a 4-point Likert scale with 0 = not at all ⁄not relevant, 1 = a little, 2 = a lot, and 3 = very much. The score from each item is summed, and the maximum total score is 30 while the minimum score is 0. Higher score means highest (adverse) effect on participant's life.

The Patient-Oriented Eczema Measure (POEM) is a 7-item questionnaire for assessing disease symptoms including dryness, itching, flaking, cracking, sleep loss, bleeding, and weeping occurring in the past week. Each item is scored on a 5-point scale with 0 = no days, 1 = 1 to 2 days, 2 = 3 to 4 days, 3 = 5 to 6 days, and 4 = every day. The total POEM score is calculated by summing the score of each item resulting in a maximum of 28 and a minimum of 0, with higher values indicating severe disease

The 5-D Itch Scale is a questionnaire consisting of 5 items used specifically to measure the course of itch by asking for the degree, duration, disability and distribution of the pruritus within the last 2 weeks. The scores from each item are summed, with maximum score of 25 and minimum score of 5. Higher score represent worse outcome
