Brief Summary
Prospective, multi-country, non-interventional study in patients with CSU where the treatment decision prior enrolment has been made to either escalate current sgH1-AHs treatment or escalate/switch current treatment to remibrutinib. The primary aim of this study is to gather real-world effectiveness and safety data for remibrutinib, a new treatment option, covering a broader, real-world clinical practice population.

Outcome Measures
Primary Outcomes (2)
UCT7 score
Urticaria Control Test is looking retrospectively for 7 days (UCT7) and consists of 4 questions. Each question is scored 0-4, with a total score range of 0 (poor control) to 16 (well controlled).
12 weeks after initiating remibrutinib treatment
UAS7 score
Urticaria Activity Score over 7 days UAS7 is based on 2 daily questions scored 0-3 per day, ranging from 0 (complete control) to 42 (poor control)
12 weeks after initiating remibrutinib treatment
Secondary Outcomes (32)
Number and proportion of participants with well-controlled disease and complete disease
Up to 24 months
Change from baseline (CFB) in UCT score
Up to 24 months
Change from Baseline in UAS7 score ≥ minimal important difference
Up to 24 months
Change in angioedema activity score (AAS7) from baseline
Up to 24 months
Number of weeks without angioedema
Up to 24 months
- +27 more secondary outcomes
Study Arms (3)
Cohort 1
Inadequate control of CSU despite licensed dose of sgH1-AH (no other pre-treatments permitted) and decision to escalate sgH1-AH treatment
Cohort 2
Inadequate control of CSU despite licensed dose or escalated sgH1-AH(s) (no other pre-treatment with exception of first generation H1-AH permitted) with decision to switch to remibrutinib treatment as per local label
Cohort 3
Any other treatment received in addition to H1-AH, any time during patients' CSU treatment history, with decision to switch to remibrutinib treatment as per local label
Eligibility Criteria
Patients with CSU where the treatment decision prior enrolment has been made to either escalate current sgH1-AHs treatment or escalate/switch current treatment to remibrutinib
You may qualify if:
- Patients with a confirmed diagnosis of primary CSU by the treating physician.
- Aged at least 18 years on the date of enrolment.
- Written informed consent of the patient to participate in the study (according to country specifications) and willingness to complete full follow-up period of 24 months.
- Cohort 1: Inadequate control of CSU despite licensed dose of sgH1-AH (no other pre-treatments permitted) and decision (independent of study enrolment) to escalate sgH1-AH treatment.
- Cohort 2: Inadequate control of CSU despite licensed dose or escalated sgH1-AH(s) (no other pre-treatment with exception of first generation H1-AH permitted) with decision (independent of study enrolment) to switch to remibrutinib treatment as per local label.
- Cohort 3: Any other treatment received in addition to H1-AH, any time during patients' CSU treatment history, with decision (independent of study enrolment) to switch to remibrutinib treatment as per local label. Note, occasional steroid rescue medication is out of scope for cohort definition. If a patient had been on continuous steroids for at least three weeks during treatment history, they will be included in cohort 3.
- Note: Candidate patients must not have initiated the next escalated treatment step (i.e. up dosed AH for cohort 1, or remibrutinib for cohorts 2 and 3) prior to their enrolment to ensure the baseline visit captures their clinical status before treatment escalation.
You may not qualify if:
- Currently enrolled in a clinical trial or on any experimental treatment.
- Patients within the safety follow-up phase of a previous interventional or non-interventional study.
- Patients who received remibrutinib as an investigational medical product during a remibrutinib interventional study or MAP/PSDS at any time in the past.
- Patients not capable or willing to continuously provide ePRO/eDiary data via electronic means throughout the duration of the study.
- Patients who are treated with remibrutinib outside of the local label.
