PrimaryPercentage of Subjects From Core Studies (CQGE031C2302 and CQGE031C2303), Receiving the Same Dose Regimen as in the Core Studies, With Well-controlled Disease (UAS7 ≤ 6) at Week 12Week 12 of the extension study
The Urticaria Activity Score (UAS) is a composite, diary-recorded score with numeric severity intensity ratings (0=none to 3=intense/severe) for the number of wheals (hives) and the intensity of the pruritus (itch) over the past 12 hours (twice daily). The daily UAS is calculated as the average of the morning and evening scores. The UAS7 is the weekly sum of the daily UAS, which is the composite score of the intensity of pruritus and the number of wheals. UAS7 scores ranged from 0 to 42. A higher UAS7 indicated greater urticaria disease activity. A minimum of 4 out of 7 daily scores were needed to calculate the UAS7 values. Otherwise, the weekly score was missing for that week. The percentage of subjects transitioning from CQGE031C2302 and CQGE031C2303 and receiving the same dose regimen as in the core studies with UAS7≤ 6 at Week 12 was estimated using multiple imputation method. The 95% confidence interval was derived based on the Wilson score method with continuity correction.

Week 12 of the extension study
The Urticaria Activity Score (UAS) is a composite, diary-recorded score with numeric severity intensity ratings (0=none to 3=intense/severe) for the number of wheals and the intensity of the pruritus over the past 12 hours (twice daily). The daily UAS is calculated as the average of the morning and evening scores. The UAS7 is the weekly sum of the daily UAS, which is the composite score of the intensity of pruritus and the number of wheals. UAS7 scores ranged from 0 to 42. A higher UAS7 indicated greater urticaria disease activity. A minimum of 4 out of 7 daily scores were needed to calculate the UAS7 values. Otherwise, the UAS7 was missing for that week. Missing data was considered as non-responder. The percentage of subjects transitioning from core studies (CQGE031C2302 and CQGE031C2303) and receiving the same dose regimen as in the core studies who achieved UAS7 ≤ 6 at week 12 in the core studies with UAS7≤ 6 at Week 12 of the extension study was estimated based on observed data.

The Urticaria Activity Score (UAS) is a composite, diary-recorded score with numeric severity intensity ratings (0=none to 3=intense/severe) for the number of wheals (hives) and the intensity of the pruritus (itch) over the past 12 hours (twice daily).

The Urticaria Activity Score (UAS) is a composite, diary-recorded score with numeric severity intensity ratings (0=none to 3=intense/severe) for the number of wheals (hives) and the intensity of the pruritus (itch) over the past 12 hours (twice daily). The daily UAS is calculated as the average of the morning and evening scores. The UAS7 is the weekly sum of the daily UAS, which is the composite score of the intensity of pruritus and the number of wheals. UAS7 scores ranged from 0 to 42. A higher UAS7 indicated greater urticaria disease activity. A negative change score from extension study baseline indicates improvement. A minimum of 4 out of 7 daily scores were needed to calculate the UAS7 values. Otherwise, the weekly score was missing for that week. The absolute change from extension study baseline in the UAS7 at Week 12 was estimated using multiple imputation method.
SecondaryChange From Extension Study Baseline in the ISS7 at Week 12 in All Subjects From Core Studies (CQGE031C2302 and CQGE031C2303) Receiving the Same Dose Regimen as in the Core StudiesExtension study baseline (Week 0), Week 12 of the extension study
The Itch Severity Score (ISS) was recorded by the subject twice daily in their eDiary, on a scale of 0 (none) to 3 (intense/severe). A weekly score (ISS7) was derived by adding up the average daily scores of the 7 preceding days. The ISS7 ranged from 0 to 21. A higher ISS7 indicated more severe itching. A negative change score from baseline indicates improvement. A minimum of 4 out of 7 daily scores were needed to calculate the ISS7 values. Otherwise, the weekly score was missing for that week. The absolute change from extension study baseline in the ISS7 at Week 12 in all subjects from core studies (CQGE031C2302 and CQGE031C2303) receiving the same dose regimen as in the core studies was estimated using multiple imputation method.
SecondaryChange From Extension Study Baseline in the HSS7 at Week 12 in All Subjects From Core Studies (CQGE031C2302 and CQGE031C2303) Receiving the Same Dose Regimen as in the Core StudiesExtension study baseline (Week 0), Week 12 of the extension study
The Hive Severity Score (HSS) was recorded by the subject twice daily in their eDiary, on a scale of 0 (none) to 3 (\> 12 hives/12 hours). A weekly score (HSS7) was derived by adding up the average daily scores of the 7 preceding days. The HSS7 ranged from 0 to 21 A higher HSS7 indicated a greater number of hives. A negative change score from baseline indicates improvement. A minimum of 4 out of 7 daily scores were needed to calculate the HSS7 values. Otherwise, the weekly score was missing for that week. The absolute change from extension study baseline in the HSS7 at Week 12 in all subjects from core studies (CQGE031C2302 and CQGE031C2303) receiving the same dose regimen as in the core studies was estimated using multiple imputation method.
SecondaryCumulative Number of Angioedema-free Weeks (AAS7=0) up to Week 12 in All Subjects From Core Studies (CQGE031C2302 and CQGE031C2303) Receiving the Same Dose Regimen as in the Core StudiesFrom extension study baseline (Week 0) up to Week 12 of the extension study
The Weekly angioedema activity score (AAS) is a validated tool to assess occurrence of episodes of angioedema. If the subject reported the occurrence of angioedema ("opening question") with "no", AAS score for this day was 0. If "yes" was the answer to the opening question, the subject continued to answer questions about the duration, severity and impact on daily functioning and appearance of the angioedema. A score between 0 and 3 was assigned to every answer field. The AAS7 was the weekly sum of the daily AAS. AAS7 scores ranged from 0-105. Higher score indicated more severe disease. AAS7 in all subjects from core studies (CQGE031C2302 and CQGE031C2303) receiving the same dose regimen as in the core studies was estimated using multiple imputation method. The imputed AAS7 = 0 was used for the cumulative number of weeks that subjects achieved AAS7 = 0 response calculation
SecondaryPercentage of Subjects From Core Studies (CQGE031C2302 and CQGE031C2303), Receiving the Same Dose Regimen as in the Core Studies, With DLQI = 0-1 at Week 12Week 12 of the extension study
The Dermatology Life Quality Index (DLQI) is a 10-item dermatology-specific quality of life (QoL) measure. Subjects rated their dermatology symptoms as well as the impact of their skin condition on various aspects of their lives thinking about the previous 7 days. An overall score was calculated and ranged from 0 to 30. Higher scores indicated worse disease-related QoL. A DLQI score of 0 or 1 indicated that there was no impact of a skin disease on the patient's life. The percentage of subjects from core studies (CQGE031C2302 and CQGE031C2303) receiving the same dose regimen as in the core studies with DLQI = 0-1 at Week 12 was estimated using multiple imputation method.
SecondaryPercentage of Subjects With Well-controlled Disease (UAS7 ≤ 6) 12 Weeks After Starting Self-administrationWeek 24 of the extension study
The Urticaria Activity Score (UAS) is a composite, diary-recorded score with numeric severity intensity ratings (0=none to 3=intense/severe) for the number of wheals (hives) and the intensity of the pruritus (itch) over the past 12 hours (twice daily). The daily UAS is calculated as the average of the morning and evening scores. The UAS7 is the weekly sum of the daily UAS, which is the composite score of the intensity of pruritus and the number of wheals. UAS7 scores ranged from 0 to 42. A higher UAS7 indicated greater urticaria disease activity. A minimum of 4 out of 7 daily scores were needed to calculate the UAS7 values. Otherwise, the weekly score was missing for that week. Missing data was considered as non-responder in the analysis. The percentage of subjects with UAS7≤ 6 at Week 24 (i.e., 12 weeks after starting self-administration) was estimated based on observed data.
