Is this trial a fit for you?
✓Likely a good fit
Adults with moderate to severe hidradenitis suppurativa who completed the full 68-week core studies (CLOU064J12301 or CLOU064J12302) and meet safety criteria.
✕Probably not a fit
Patients who discontinue early, do not transition to commercial remibrutinib, or do not derive benefit during the extension may not experience additional improvements.

What this trial studies
This is a global Phase 3 extension study for adults with moderate to severe hidradenitis suppurativa who completed preceding trials. It uses a double-blind, double-dummy design during the core period and then transitions to an open-label phase, allowing continued treatment until a commercial option is available or up to four years. Participants keep the same blinded regimen from the prior treatment period through the end of the core studies, and may transition to open-label remibrutinib thereafter. The study aims to assess long-term safety, tolerability, and efficacy, with eligibility limited to those who completed 68 weeks of the core trials and meet safety criteria. The sponsor is Novartis Pharmaceuticals, with participating sites in select U.S. dermatology centers.
Why it matters
Potential benefit: If successful, participants may experience continued symptom control and extended access to remibrutinib during the extension period.
How similar studies have gone: Similar BTK inhibitor extensions have shown continued safety and potential efficacy in long-term HS management, but this extension adds post-trial access and open-label treatment.

Show full inclusion / exclusion criteria
Key Inclusion Criteria: * Signed informed consent must be obtained before any assessment is performed. * Participant has completed the full study treatment period according to the protocol (68 weeks) in the core studies (CLOU064J12301 or CLOU064J12302). * Participant does not meet any treatment discontinuation criteria of the core study at Week 68. Key Exclusion Criteria: * Ongoing or planned use of prohibited HS or non-HS treatments. * Participants not expected to benefit from participation in the extension study or participants expected to be exposed to an undue safety risk if participating in the extension study, as assessed by the Investigator. * Current severe progressive or uncontrolled disease, which in the judgment of the Investigator renders the participant unsuitable for the study. Other protocol-defined inclusion/exclusion criteria may apply.
