Remibrutinib Open Label Roll-over Post-trial Access Protocol

There will be no screening period for this study. After completion of the appropriate consent process, eligible participants can start treatment with remibrutinib as soon as they enter the study. All participants must visit the study site for their enrollment visit to confirm eligibility and commence study participation. Participants will return to the study center at least every 16 weeks for resupply of study medication but may return earlier if needed.

Participants will receive remibrutinib at the dose and regimen they last received in the parent study.

Participants will continue to receive remibrutinib for up to 3 years or until one of the following occurs: no treatment benefit, participant wishes to discontinue trial participation or withdraws consent, protocol non-compliance, pregnancy, the investigator feels it is no longer in the participant's best interest to continue therapy, or the participant receives access to treatment with remibrutinib outside of a clinical study, whichever occurs first.

Inclusion criteria

• Participant has completed treatment per protocol in a Novartis study of remibrutinib (unless otherwise specified in a parent study protocol) in a dermatological or allergology indication.

Participants, who derive benefit from the treatment with remibrutinib but have not completed the treatment in certain parent studies due to parent study termination by Novartis, may be eligible if the termination was due to reasons other than safety or lack of efficacy (e.g., technical / administrative reasons).

• Participant is deriving benefit from remibrutinib, investigator believes he/she would continue to derive benefit from remibrutinib and the benefit outweighs the risk, based on the investigator's judgement.
• Participant is unable to obtain access to the marketed remibrutinib formulation per local post study drug supply program, prescription and/or reimbursement guidelines.

Exclusion criteria

Participants meeting any of the following criteria are not eligible for inclusion in this study.

• Participant has prematurely discontinued study treatment in the parent study.
• Use of prohibited medications
