A 52-week multi-center, randomized, double-blind, placebo controlled, basket study with an open-label extension to investigate the efficacy, safety, and tolerability of remibrutinib (LOU064) in Chronic Inducible Urticaria (CINDU) in adults inadequately controlled by H1-antihistamines

Who can take part

• 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 : • Symptomatic Dermographism: A Total Fric Score of ≥3 using the FricTest® 4.0 and a numerical rating scale score of ≥5 for itch after the provocation test. • Cold Urticaria: A Critical Threshold Temperature of ≥15°C using the TempTest® 4.0 and a numerical rating scale score of ≥5 for itch after the provocation test. • Cholinergic Urticaria: A physician global assessment of severity of hives ≥ 2 using the Pulse-controlled ergometry test and a numerical rating scale score of ≥5 for itch after the provocation test
• Cold Urticaria
• Cholinergic urticaria: XX

Who cannot take part

• Previous use of remibrutinib or other BTK inhibitors
• 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
• 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
• 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
