Measure
Tralokinumab Subcutaneous Dosing by an Autoinjector
An initial SC dose of 600 mg tralokinumab at baseline followed by self-administration of a 300 mg dose of tralokinumab every other week for 14 weeks. Tralokinumab: Tralokinumab is a human recombinant monoclonal antibody of immunoglobulin G4 (IgG4) subclass that specifically binds to human interleukin-13 (IL-13) and blocks interaction with the IL-13 receptors. It is presented as a liquid formulation for subcutaneous administration

PRIMARY outcome

Timeframe: At Week 16

Population: FAS, full analysis set

Eczema Area and Severity Index (EASI) is a validated measure used in clinical practice and clinical trials to assess the severity and extent of AD. EASI is a composite index with scores ranging from 0 to 72, where higher values indicate a more severe or more extensive condition
