Remibrutinib in Real-world Clinical Practice - a US Sub-study

Novartis Pharmaceuticals505 enrolled

Overview

Prospective, 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.

This is a prospective, 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. This local US study is part of an umbrella design which brings the evidence needs from multiple countries under the REASSERT global program (CLOU064A2402).

Eligibility

Sex: ALLMin age: 18 YearsMax age: 100 Years

Medical Language ↔ Plain English

Inclusion Criteria: * 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. Exclusion Criteria: * 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.

Time frame: 12 weeks after initiating remibrutinib treatment

Secondary Outcomes

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).

Time frame: 12 weeks after initiating remibrutinib treatment

Proportion of patients with UCT score ≥12 and UAS7 score ≤6. Urticaria Control Test (UCT) consists of 4 questions scored 0 (very much) to 4 (not at all), with a total score range of 0 to 16. 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.

Time frame: Up to 24 months

Change from baseline (CFB) in UCT score

Change in UCT score over time. Urticaria Control Test (UCT) consists of 4 questions scored 0 (very much) to 4 (not at all), with a total score range of 0 to 16. Highest scores indicates better disease control. The study is not powered to detect any specific difference and the purpose is to estimate any observed difference descriptively.

Time frame: Up to 24 months

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. Lower scores suggests urticaria free and well controlled urticaria. The study is not powered to detect any specific difference and the purpose is to estimate any observed difference descriptively.

UAS7 score

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.
