A Study to Investigate the Pharmacokinetics and Safety of Remibrutinib in Participants With Hepatic Impairment Compared With Matched Healthy Participants

• Status: Recruiting
• Trial end date: 2023-03-08

Summary

This study will be conducted in 2 parts. Part 1 will comprise of participants with mild and moderate HI and matching healthy control participants with normal hepatic function. Part 2 will comprise of participants with severe HI and matching healthy control participants with normal hepatic function.

Each study part will comprise of a screening period of up to 28 days, a baseline evaluation on Day -1, and a treatment period including up to 8 days of safety and PK data collection. Participants will be domiciled from Day -1 through Day 8.

All participants will receive 25 mg remibrutinib b.i.d. orally on Days 1 and 2, and a morning oral dose of 25 mg remibrutinib on Day 3. PK samples will be collected pre dose on Day 3 and until 72 hours post Day 3 dosing. Throughout the study, safety assessments will include physical examinations, ECGs, vital signs, clinical laboratory evaluations (hematology, chemistry, urinalysis and coagulation) and AE / serious adverse event (SAE) monitoring.

The Investigator and Novartis will conduct a joint interim review of safety and PK data from Part 1 before proceeding to Part 2.

Part 2 will only begin if administration of remibrutinib in Part 1 is deemed safe and tolerable by the Investigator and Novartis to proceed in participants with severe HI. Depending on the outcome of the interim review, administration of a lower dose of remibrutinib in severe HI participants and their matching healthy control participants may be considered.

Part 2 will also include sentinel dosing where one participant with severe HI will receive the first dose of remibrutinib at least 1 week before the remaining participants. If the Investigator concludes that there are no emergent safety concerns for the sentinel participant, then dosing will commence for the remaining participants.

Study Completion evaluations will occur on Day 8, followed by a post-study safety follow up contact (e.g. follow-up telephone call, email) approximately 30 days after the last administration of study treatment. The total study duration for each participant is expected to be up to approximately 62 days, including the Screening period and the follow-up contact.
