About this study
Official title: 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
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
Read the detailed 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:
- 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

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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
Detailed 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:
- 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

- 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.
Key exclusion criteria (7 listed)
- 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
Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.

Primary outcome
Proportion of participants with complete response in Total Fric Score; symptomatic dermographism
Time frame: Week 12
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)
Proportion of participants with complete response in critical temperature threshold; cold urticaria
Time frame: Week 12
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.
Proportion of participants with itch numerical rating scale =0; cholinergic urticaria
Time frame: Week 12
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")
21 secondary outcomes

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of participants with complete response in Total Fric Score; symptomatic dermographism (time frame: Week 12). The study lists 3 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 15 Oct 2026.
