ListOutcomeTime frameDescription
PrimaryChange From Baseline in Weekly Urticaria Score (UAS7) at Week 12 (Scenario 1 With UAS7 as Primary Efficacy Endpoint)Baseline, Week 12
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. This endpoint is a secondary endpoint for testing strategy Scenario 2 with Weekly Itch Severity Score (ISS7) and Weekly Hives Severity Score (HSS7) as co-primary efficacy endpoints).
PrimaryChange From Baseline in Weekly Itch Severity Score (ISS7) at Week 12 (Scenario 2 With ISS7 and HSS7 as Co-primary Efficacy Endpoints)Baseline, Week 12
The severity of the itch was recorded by the participant twice daily in their electronic Diary, on a scale of 0 (none) to 3 (severe). A weekly score (ISS7) was derived by adding up the average daily scores of the 7 days preceding the visit. The possible range of the weekly score was therefore 0 - 21 (highest itch severity). This endpoint is a secondary endpoint for testing strategy Scenario 1 with Weekly Urticaria Activity Score (UAS7) as the primary efficacy endpoint).
PrimaryChange From Baseline in Weekly Hives Severity Score (HSS7) at Week 12 (Scenario 2 With ISS7 and HSS7 as Co-primary Efficacy Endpoints)Baseline, Week 12
The hives (wheals) severity score, defined by number of hives, was recorded by the participant twice daily in their electronic Diary, 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 days preceding the visit. The possible range of the weekly score was therefore 0 - 21 (highest hives activity). This endpoint is a secondary endpoint for testing strategy Scenario 1 with Weekly Urticaria Activity Score (UAS7) as the primary efficacy endpoint.
SecondaryNumber of Patients Who Achieved Disease Activity Control (UAS7 ≤6)Week 12
The percentage of patients achieving disease activity control (UAS7 =\< 6) at Week 12 was assessed to evaluate the efficacy of Remibrutinib in Chronic Spontaneous Urticaria (CSU) patients. The UAS7 is the sum of the Weekly Hives Severity Score (HSS7) and the Weekly Itch Severity Score (ISS7). The possible range of the UAS7 score is 0 - 42 (highest hives and itch severity).
SecondaryNumber of Patients Who Achieved Complete Absence of Hives and Itch (UAS7 = 0)Week 12
The number of patients achieving complete absence of hives and itch (UAS7 = 0) at Week 12 was assessed to evaluate the efficacy of Remibrutinib in Chronic Spontaneous Urticaria (CSU) patients. The UAS7 is the sum of the Weekly Hives Severity Score (HSS7) and the Weekly Itch Severity Score (ISS7). The possible range of the UAS7 score is 0 - 42 (highest hives and itch severity).
SecondaryNumber of Patients With Early Onset of Disease Control (UAS7 ≤ 6 at Week 2)Week 2
The percentage of patients achieving disease activity control (UAS7 =\< 6) at Week 2 was assessed to evaluate the efficacy of Remibrutinib in Chronic Spontaneous Urticaria (CSU) patients. The UAS7 is the sum of the Weekly Hives Severity Score (HSS7) and the Weekly Itch Severity Score (ISS7). The possible range of the UAS7 score is 0 - 42 (highest hives and itch severity).
SecondaryCumulative Number of Weeks With Disease Activity Control (UAS7 <= 6) up to Week 12up to Week 12
Maintaining disease activity control was assessed as cumulative number of weeks with an UAS7 =\< 6 response between baseline and Week 12. The UAS7 is the sum of the Weekly Hives Severity Score (HSS7) and the Weekly Itch Severity Score (ISS7). The possible range of the UAS7 score is 0 - 42 (highest hives and itch severity).
SecondaryNumber of Patients Who Achieved DLQI = 0 - 1Week 12
The Dermatology Life Quality Index (DLQI) is a 10-item (grouped in 6 domains) dermatology-specific quality of life (QoL) measure. Participants are rating 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 is calculated and ranges from 0 to 30 (higher score meaning worse disease-related QoL). Domain scores are calculated for: Symptoms and Feelings (0-6), Daily Activities (0-6), Leisure (0-6), Work and School (0-3), Personal Relationships (0-6), Treatment (0-3). The overall DLQI score range was split into score bands and validated in terms of their meaning/relevance to patients overall. DLQI = 0-1 means no effect on patient's life.
SecondaryCumulative Number of Weeks Without Angioedema (AAS7 = 0)Up to Week 12
Angioedema occurrence was recorded once daily in the evening in the electronic Diary by the participant. Reporting the occurrence of angioedema was used as opening question for the assessment of the Angioedema Activity Score (AAS). The AAS consists of 5 questions with 4 answer options (scored 0-3) for each item, with a minimum score of 0 and a maximum score of 15 per day. The AAS score over 7 days (AAS7) ranges from 0 (no angioedema episodes) to 105 (highest angioedema severity).
SecondaryNumber of Participants With Adverse EventsOn-treatment adverse events are reported from first dose of study medication up to 28 days after last dose of study medication, for a timeframe up to approximately 56 weeks
An adverse event (AE) is any untoward medical occurrence (e.g., any unfavorable and unintended sign \[including abnormal laboratory findings\], symptom or disease) in a clinical investigation participant after providing written informed consent for participation in the study. Therefore, an AE may or may not be temporally or causally associated with the use of a medicinal (investigational) product.
