Efficacy and Safety of MEDI3506 in Adult Subjects With Atopic Dermatitis
A Phase 2 Randomized, Double-blinded, Placebo-controlled Study to Evaluate the Efficacy and Safety of MEDI3506 in Adult Subjects With Moderate-to-severe Atopic Dermatitis
Study Overview
Detailed Description
This is a research study to determine the efficacy and safety of investigational drug MEDI3506 for the treatment of adult subjects with Atopic Dermatitis.
Each participant will be assigned randomly to a treatment arm, which could be different strengths of the active treatment or a placebo which does not contain active treatment. Both Participants and investigators will be masked to the treatment assignment.
Approximately 152 participants will take part in this study. There is a 4 weeks screening period to determine eligibility. After eligibility is confirmed, participants will receive investigational drug or placebo during the 16 weeks treatment period. This is then followed by an 8-week follow-up period.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percent Change From Baseline to Week 16 in EASI Score
Time Frame: Week 16
|
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.

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
