A Study to Investigate Efficacy, Safety, and Tolerability of Remibrutinib Compared With Placebo in Adults With CINDU Inadequately Controlled by H1-antihistamines
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.
Study details:
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:. * Screening period (up to 4 weeks): During the screening period, participants who have provided informed consent will be assessed for study eligibility. * Double-blind, placebo-controlled treatment period (24 weeks): 24 weeks of double-blind treatment with remibrutinib or placebo.
* Open-label treatment period (28 weeks): 28 weeks of open-label treatment with remibrutinib. * Follow-up period: 4 weeks of treatment free follow-up. The open-label extension period consists of observation and treatment period.
At the end of the core period of the study, if participants continue to experience symptoms, they will transition to the treatment period in OLE. If they do not experience symtpoms they will transition to the observation period in the OLE. 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.

What is the study measuring?
Primary outcome
| Primary Outcome Measure | Primary Outcome Description | Primary Outcome Time Frame |
|---|---|---|
| Proportion of participants with complete response in Total Fric Score; symptomatic dermographism | Total Fric score (a scale from 0-4 where a positive response with all of the four pins is TFS = 4, while a positive response with only one pin - the largest pin is TFS = 1) | Week 12 |
| Proportion of participants with complete response in critical temperature threshold; cold urticaria | The Temptest is used to induce itch and hives in participants with cold urticaria. Critical temperature threshold (CTT), as measured by the Temptest, determines the highest temperature that induces symptoms. | Week 12 |
| Proportion of participants with itch numerical rating scale =0; cholinergic urticaria | Itch numerical rating scale, a scale from 0 to 10 Patients are asked to rate itching severity based on the worst level of itching in the past 24 h using an 11-point scale from 0 ("no itch") to 10 ("worst itch imaginable") | Week 12 |
Secondary outcome
| Secondary Outcome Measure | Secondary Outcome Description | Secondary Outcome Time Frame |
|---|---|---|
| Change from baseline in Total Fric score; symptomatic dermographism | Total Fric score, a scale from 0-4 where a positive response with all four pins is TFS=4, while a positive only 1 pin - the largest pin is TFS=1 | Week 12 |
| Change from baseline in criticial temperature threshold following Temptest; cold urticaria | Critical temperature threshold, as measured by the Temptest, determines the highest temperature that induces symptoms | Week 12 |
| Change from baseline in itch numerical rating scale; cholinergic urticaria | Itch numerical rating scale (NRS), scale from 0 to 10. 0 ("no itch") to 10 ("worst imaginable itch"). | Week 12 |
| proportion of participants with Physician Global Assessment (PGA) severity of hives =0; cholinergic urticaria | Physician global assessment of severity of hives. This assessment is scored 0 to 4 with 0=no hives, 1=mild hives, 2=moderate hives, 3=severe hives and 4=very severe hives | Week 12 |
| Proportion of participants with complete response in TFS; symptomatic dermographism | Total Fric score (a scale from 0-4 where a positive response with all of the four pins is TFS = 4, while a positive response with only one pin - the largest pin is TFS = 1) | Week 24 |

A DLQI score of 0 or 1 means that there is no impact of a skin disease on the patient's life. | Week 12 |
