Is this trial a fit for you?

Likely a good fit

Adults (18+) with a confirmed CSU diagnosis who are switching to or escalating to remibrutinib as per local labeling and who provide informed consent and agree to 24 months of follow-up.

Probably not a fit

Patients who do not respond to remibrutinib in real-world use or who discontinue early may not experience benefit during the study.

What this trial studies

This is a prospective, non-interventional study conducted in Germany as part of the global REASSERT program. It collects real-world data on effectiveness and safety of remibrutinib in adults with CSU who switch or escalate to remibrutinib per local labeling. The study follows participants for up to 24 months to observe outcomes in routine practice, without randomization or imposed interventions. Data will come from patients’ medical records and patient reports to reflect everyday treatment decisions outside of a controlled trial setting.

Why it matters

Potential benefit: If successful, the study could validate remibrutinib's real-world effectiveness and safety, informing clinicians and patients about expected outcomes in typical practice.

How similar studies have gone: Real-world observational data for remibrutinib and similar targeted therapies have shown useful insights in CSU management, though country-specific results may vary.

Inclusion Criteria:

7.2.1 Inclusion criteria Patients must meet all the following criteria to be eligible for inclusion in this study.

1. Patients with a confirmed diagnosis of primary CSU by the treating physician.
2. Aged at least 18 years on the date of enrollment.
3. Written informed consent of the patient to participate in the study and willingness to complete full follow-up period of 24 months.
4. Cohort-specific observational inclusion criteria:

   1. 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 enrollment) to switch to remibrutinib treatment as per local label.
   2. Cohort3: Any other treatment received in addition to H1-AH, any time during patients' CSU treatment history, with decision (independent of study enrollment) 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 3 weeks during treatment history, they will be included in cohort 3.

Exclusion Criteria:

Patients are excluded if they meet any of the following criteria:

1. Simultaneous participation in any investigational trial or simultaneous participation in another Novartis-sponsored non-interventional study with remibrutinib.
2. Patients within the safety follow-up phase of a previous interventional or non-interventional study.
3. Patients who received remibrutinib at any time in the past.
4. Patients not capable or willing to continuously provide ePRO/eDiary data via electronic means throughout the duration of the study.
5. Patients who are treated with remibrutinib outside of the local label.
