E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary study objectives are: 1) To generate descriptive data on the efficacy and safety of dose escalation to upadacitinib 30 mg QD and dose reduction to upadacitinib 15 mg QD based on a clinical response after 12 weeks of treatment. This data will inform the clinical management for subjects with moderate to severe AD treated with both approved doses of upadacitinib. 2) To generate evidence on the subject impact of upadacitinib treatment decision-making based on targeting at least a 90% reduction in Eczema Area and Severity Index (EASI 90) skin clearance (Treat to Target). |
