Number of participants with an Urticaria Control Test score of greater than or equal to 12 at Week 12 The UCT is a simple 4-item tool. A score between 0 and 4 is assigned to every answer option. Subsequently, the scores for all 4 questions are summed up. Accordingly, the minimum and maximum UCT scores are 0 and 16, with 16 points indicating complete disease control.
2 patients with angioedema status were missing at baseline and not included
A total score of UAS7 is calculated by adding for 7 days the daily UAS. The UAS7 is the sum of the daily UAS over 7 days before baseline and W12. The UAS7 score ranges from 0 to 42 with higher scores reflecting higher activity of the disease. Scores were categorized into five diseases states : urticaria-free (score =0), well-controlled (scores 1-6), mild (scores 7-15), moderate (scores 16-27) and severe urticaria (scores 28-42).
The UCT is a questionnaire collecting retrospective information over the last 4 weeks before baseline and W12. The UCT score ranges from 0 to 16 with higher scores reflecting lower control of the disease. A score of ≥12 indicates well-controlled urticaria.
The UCT is a simple 4-item tool. A score between 0 and 4 is assigned to every answer option. Subsequently, the scores for all 4 questions are summed up. Accordingly, the minimum and maximum UCT scores are 0 and 16, with 16 points indicating complete disease control.

The Cu-QoL is a questionnaire collecting retrospective information over the last 2 weeks before baseline and W12. The CU-QoL total score is transformed to range from 0 to 100, with higher scores indicating worse Health Related Quality of life.
The angioedema Quality of Life Questionnaire is a valuable tool to assess changes of QoL impairment in angioedema patients. The results of all the answered questions are summed up and transferred to a scale ranging from 0 to 100, with higher scores indicative of a higher QoL impairment
The Dermatology life Quality Index (DLQI) is a ten-question questionnaire used to measure the impact of skin disease on the quality of life of an affected person. It is designed for people aged 16 years and above. Each question is scored from 0 to 3, giving a possible score range form 0 (meaning no impact of skin disease on quality of life) to 30 (meaning maximum impact on quality of life).

The Angioedema Activity Score (AAS) was completed by patients on a daily basis. The AAS is a validated questionnaire to determine the severity and impact of the angioedema episode. Te daily AAS values are added over 7 days before baseline and W12. Weekly AAS (AAS7) scores range from 0 to 105, with higher scores indicative of a higher disease activity.
