Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: 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

Who may be able to join

  • 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-specific observational inclusion criteria:
  • 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.

Who cannot join

  • 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.

About this study

Official title: Remibrutinib in Real-world Clinical Practice: a Prospective, Multi-country, Non-interventional, Effectiveness and Safety Study

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.

Read the detailed description

This is a 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, covering a broader, real-world clinical practice population. The study employs an umbrella design which brings the evidence needs from multiple countries under the REASSERT global program. Countries will generate local protocol to be used in their country; the local study documentation will be a minimised version of the global document, modified to align with country's evidence needs, given local disparities in treatment guidelines, access, physician type and ePROs/eDiaries used. To achieve the core objectives the observation needs to include either the Urticaria Control Test (UCT) or Urticaria Activity Score over 7 days (UAS7) and the Dermatology Life Quality Index (DLQI). Data from all countries will be pooled and analyzed globally. In certain instances, some modifications of the global protocol may be permitted. For example, in countries where prospective monitoring of off-label antihistamines is prohibited, cohort 1 will not be enrolled.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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).

    Measured: 12 weeks after initiating remibrutinib treatment

  2. 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)

High scores indicates better disease control. Urticaria Activity Score over 7 days (UAS7) is based on 2 daily questions, with daily score of 0 to 6 and weekly score of 0 to 42. Lower scores suggests urticaria free and well controlled urticaria.

    Measured: Up to 24 months

  3. Change from Baseline in UAS7 score ≥ minimal important difference

    Urticaria Activity Score over 7 days (UAS7) is based on 2 daily questions, with daily score of 0 to 6 and weekly score of 0 to 42.

    Measured: Up to 24 months

  4. Change in angioedema activity score (AAS7) from baseline

    Angioedema Activity Score (AAS7) is assessing disease activity over 7 days in patients with urticaria. The score is based on 5 daily questions scored 0 (no discomfort) to 3 (severe discomfort), with weekly score ranging from 0 to 15. Higher scores indicates greater severity of angioedema.

    Measured: Up to 24 months

  5. Number of weeks without angioedema

    Number of weeks without angioedema evaluated using AECT and/or application entries. Angioedema Control Test (AECT) consists of 4 questions evaluating swelling, rated from 0 (not at all) to 4 (very often) with a maximum score of 16, higher score indicating better control.

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Spontaneous Urticaria, run by Novartis Pharmaceuticals at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 16 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Novartis Pharmaceuticals (1-888-669-6682, novartis.email@novartis.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

UCT7 score (time frame: 12 weeks after initiating remibrutinib treatment). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Apr 2026.
