SECONDARY outcome

Timeframe: Day 1 to Week 4

Population: Total number of participants assessed is equal to 27, the count of subjects that completed Week 4 visits.

The Total Fric Score represents the total number of linear wheals with a width of ≥3 mm induced following the Fric Test, from 0 to 4; 0 representing the minimum score (better outcome), and 4 representing the maximum score (worse outcome). A complete response is equal to a response of 0, where a subject began with at least a score of 1. A partial response is equal to a decrease of at least 2 points in the score (wheals), where a subject began with at least a score of 2. Partial responders may also be considered complete responders if their final score is equal to 0.

SECONDARY outcome

Timeframe: Day 1 to Week 4

Population: Total number of participants assessed is equal to 27, the count of subjects that completed Week 4 visits.

The Pruritus Severity is determined based on the Pruritus Numeric Rating Scale, or P-NRS. This is an 11-point scale completed by the subject prior to and approximately 10 minutes after completion of the provocation test, where 10 represents the worst itch (maximum), and 0 represents no itch (minimum) at the site of the urticaria provocation test.
