Study Endpoints

Primary Endpoints

Change From Baseline in Urticaria Activity Score Over 7 Days (UAS7) at Week 16
Baseline and Week 16

The UAS is a CSU-specific patient-reported outcome measure with 2 components: Hives Severity Score (HSS) for number of wheals and an Itch Severity Score (ISS) for itch intensity, and are each scored from 0 (no wheals, no itch) to 3 (\>50 wheals, severe itch) for the previous 24 hours. The HSS and ISS are combined to give a daily UAS ranging from 0 to 6. The sum of the daily UAS over a 7-day period provides the UAS7, from 0 (no symptoms) to 42 (severe urticaria). The least squares mean (LSM) estimates are based on the repeated measure model with stratification factor (prior anti-IgE status), baseline UAS7, treatment, study week and the interaction between treatment and study week. A negative change from baseline indicates an improvement in urticaria activity.
