Primary Outcome Measures
NameTimeMethod
Change from baseline in the urticaria activity score (UAS7)12 Weeks

Defined as the 7-day sum of the individual, daily recorded scores for HSS and ISS, at week 12. UAS scores range from 0-42; with higher scores reflecting greater disease activity.

Secondary Outcome Measures
NameTimeMethod
Proportion of participants who achieve UAS7 ≤ 6 (controlled disease) at Week 1212 Weeks

Defined as the 7-day sum of the individual, daily recorded scores for HSS and ISS, at week 12. UAS scores range from 0-42; with higher scores reflecting greater disease activity.

Time to first achievement of UAS7 ≤ 6 (controlled disease) during the PC period12 Weeks

Defined as the 7-day sum of the individual, daily recorded scores for HSS and ISS. UAS scores range from 0-42; with higher scores reflecting greater disease activity.

Proportion of participants with UAS7 = 0 at Week 12.12 Weeks

Defined as the 7-day sum of the individual, daily recorded scores for HSS and ISS, at week 12. UAS scores range from 0-42; with higher scores reflecting greater disease activity.
