Study design details

Main study objective

To retrospectively analyse the treatment outcomes of patients with severe Atopic Dermatitis (AD) who were enrolled in the Early Access to Medicines Scheme (EAMS) for dupilumab.

Outcomes

To describe the change in EASI score compared to baseline (EAMS enrolment) in patients who have received ≥ 12 weeks of treatment with dupilumab, To describe the change in IGA score compared to baseline (EAMS enrolment) in patients who have received ≥ 12 weeks of treatment with dupilumab To qualitatively describe clinician opinion about patient response to dupilumab (from retrospective review of patient notes)

Data analysis plan

The analysis mainly comprised descriptive statistics. Continuous variables were summarized using mean and standard deviation, with minimum and maximum values reported to provide the range. Categorical variables were summarized as frequency and proportion.Inferential statistics were used to assess the statistical significance of observed differences for the 16 +/-4 weeks’ timeframe. For continuous scale variables a paired samples t-test was performed. For ordinal variables a Wilcoxon Signed Ranks test was performed. Pearson’s correlations were performed to assess the relationships between different measures of severity. No imputation was performed for missing data. Missing values were excluded from relevant analyses. Precise sample sizes are reported for each analysis. The analysis was conducted using IBM SPSS Statistics software (version 24).
