Foranstaltningsbeskrivelse
Tidsramme
Change from baseline in Weekly Urticaria Activity Score (UAS7) at Week 4 (Part 1)
Tidsramme: From enrollment to the end of treatment at 4 weeks.
The Weekly Urticaria Activity Score (UAS7) is a simple scoring system to evaluate urticaria signs and symptoms. It is based on scoring wheals (hive severity score) and itch (itch severity score) separately on a scale of 0 (no signs/symptoms) to 3 (intense signs/symptoms) over 7 days. The final score is calculated by adding together the daily scores, which can range from 0 to 6, for 7 days. This results in a maximum total score of 42 (highest urticaria severity), and a minimum possible score of 0. A higher score indicates worse disease. A negative change score (week 4 score minus Baseline score) indicates improvement.
From enrollment to the end of treatment at 4 weeks.
Pharmacokinetics Cmax (Part 2)
Tidsramme: From enrollment to end of follow-up visit, up to approximately 1 week.
Cmax: Maximum Plasma Concentration
From enrollment to end of follow-up visit, up to approximately 1 week.
Pharmacokinetics AUC (part 2)
Tidsramme: From enrollment to end of follow-up visit, up to approximately 1 week.
AUC: Area Under the Concentration-time Curve
From enrollment to end of follow-up visit, up to approximately 1 week.
