A Safety and Efficacy Study of Remibrutinib in the Treatment of CSU in Japanese Adults Inadequately Controlled by H1-antihistamines
- Conditions
- Chronic Spontaneous Urticaria
- Interventions
- Drug: LOU064
- Registration Number
- NCT05048342
- Lead Sponsor
- Novartis Pharmaceuticals
- Brief Summary
The purpose of this study was to evaluate the safety, tolerability and efficacy of remibrutinib (LOU064) in adult Japanese patients chronic spontaneous urticaria (CSU), who remain symptomatic despite treatment by H1-antihistamine (H1-AH) at locally label approved doses, for a duration of 52 weeks of treatment with remibrutinib and a post-treatment follow-up period of up to 4 weeks.
- Detailed Description
The study consisted of three periods, the total study duration is up to 60 weeks: screening period of up to 4 weeks, open-label treatment period of 52 weeks (remibrutinib 25 mg b.i.d.), and a treatment free follow-up period of 4 weeks.
It was planned to include approximately 70 patients in the study; 71 patients were enrolled and included in the analyses.

Group Intervention Description LOU064 25 mg b.i.d. LOU064 Patients were treated with remibrutinib 25 mg bis in die/twice a day (b.i.d.). LOU064 open-label treatment taken orally for 52 weeks.
- Primary Outcome Measures
Name Time Method Number of Participants With Treatment Emergent Adverse Events Baseline up to 30 days after last dose of study medication, assessed 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.
Treatment emergent Adverse Event (TEAEs) in this study are events that started after the first dose of study treatment and until 30 days after the last study treatment, or events present prior to the first dose of treatment which increased in severity based on preferred term within 30 days after the last study treatment.
- Secondary Outcome Measures
Name Time Method Mean Change From Baseline in Weekly Urticaria Activity Score (UAS7) at Week 12 Baseline, Week 12 Change from Baseline in Weekly Urticaria Activity Score (UAS7) was assessed to evaluate the efficacy of Remibrutinib in Chronic Spontaneous Urticaria (CSU) patients. The Weekly Urticaria Activity Score (UAS7) is the sum of the Weekly Hives Severity Score (HSS7) and the Weekly Itch Severity Score (ISS7). The possible range of the weekly UAS7 score is 0 - 42 (highest hives and itch severity).
Number of Participants Who Achieved Disease Activity Control (UAS7 =< 6) at Week 12 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).
Number of Participants Who Achieved Complete Absence of Hives and Itch (UAS7 = 0) at Week 12 Week 12 The proportion 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).
Change From Baseline in Weekly Itch Severity Score (ISS7) at Week 12 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).
Change From Baseline in Weekly Hives Severity Score (HSS7) at Week 12 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).
Number of Participants Who Achieved Early Onset of Disease Activity 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).
Number of Participants Who Achieved Dermatology Life Quality Index (DLQI) = 0-1 at Week 12 Week 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 as follows: 0-1 (No effect on patient's life), 2-5 (Small effect on patient's life), 6-10 (Moderate effect on patient's life), 11-20 (Very large effect on patient's life), 21-30 (Extremely large effect on patient's life).
Mean Cumulative Number of Weeks With Disease Activity Control (UAS7 =< 6) up to Week 12 Up 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).
Mean Cumulative Number of Angioedema Occurrence-free Weeks (AAS7 = 0 Response) up to Week 12 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).
