About
This is a Phase 3, parallel group, placebo-controlled, double-blind, confirmatory study in patients with CINDU, with an optional Open-label Extension (OLE).
The purpose of the core period (52 weeks of treatment) of this study is to evaluate the efficacy, safety, and tolerability of remibrutinib (LOU064) vs. placebo in adults suffering from CINDU inadequately controlled by H1-antihistamines (H1-AHs).
The purpose of the OLE period is to collect long-term efficacy, safety, and tolerability data on remibrutinib in participants after having completed the Core period
Full description
This study consists of a core and extension periods.
The Core period (6 arms) has a total duration of up to 60 weeks including a double-blind placebo-controlled treatment period until Week 24 followed by open-label treatment with remibrutinib up to Week 52. The primary endpoint for all CINDU subtypes is assessed at Week 12.
The Core period consists of:
The duration of the Open-label Extension period will be approximately 3 years where participants can switch from observation to treatment depending on if they start developing symptoms. Only those participants participating in the Open-label Extension Treatment period will receive remibrutinib. The participants in the Open-label Extension Observation period will not receive remibrutinib

Inclusion and exclusion criteria
Inclusion Criteria for core period:
Male and female participants ≥18 years of age at the time of signing of the ICFs
Confirmed CINDU diagnosis (as per guidelines) for symptomatic dermographism, cold urticaria or cholinergic urticaria for ≥ 4 months (defined as onset of CINDU with supporting documentation (e.g medical record, clinical history, photographs)) and inadequate control with H1-AH at local label approved doses at the time of randomization
The following response to the provocation test for each subtype is required at the randomization visit :
Cold Urticaria: Positive ice-cube test resulting in hives at the provocation site for participants at Screening.
Cholinergic urticaria: Participants must show sweating in performing the pulse-controlled ergometry test on day of randomization. Participants with anhidrosis must not be included.
Inclusion criteria for the OLE:
Participants who have completed the Core period up to Week 52 and are willing to enter the OLE period
Exclusion Criteria for core period:
Participants who have concomitant CSU at screening. Participants with resolved CSU at the time of screening can be included in the study.
Participants who have a familial form (e.g familial cold autoinflammatory syndrome, familial cold urticaria) of the target CINDU that is being considered for the participant's inclusion in this study.
Participants having a more defined other form of inducible urticaria than the target CINDU that is being considered for the participant's inclusion in this study.
Diseases, other than chronic inducible urticaria, with urticaria or angioedema symptoms including but not limited to urticarial vasculitis, erythema multiforme, cutaneous mastocytosis (urticaria pigmentosa) and hereditary or acquired angioedema
Any other skin disease associated with chronic itching that might influence, in the investigator's opinion, the study evaluations and results (e.g., atopic dermatitis, bullous pemphigoid, dermatitis herpetiformis, senile pruritus, etc.) or skin diseases associated with only wheals and no itch e.g asymptomatic dermographism
