About this study

Official title: The Effect of Multiple Doses of Cenobamate (YKP3089) on the Single Dose Pharmacokinetics of Cytochrome P450 Substrates (midazolam, Warfarin, Omeprazole and Bupropion) Administered Orally in an Open-label, One-sequence Study in Healthy Subjects

This study is aimed to investigate the influence of cenobamate on the activity of CYP3A4/5, CYP2B6, CYP2C19, and CYP2C9 by using drugs recommended by both the FDA and EMA as in vivo probes. In order to avoid a potential pharmacokinetic interaction between the probes, midazolam (CYP3A), warfarin (CYP2C9), and omeprazole (CYP2C19) will be administered together as a validated cocktail and separately from bupropion (CYP2B6) using an adequate washout time period between the 2 assessments.

The starting daily dose of cenobamate will be 12.5 mg, which will be administered for 2 weeks. Then, daily cenobamate doses will be increased every 2 weeks to 25 mg, 50 mg, 100 mg, 150 mg, and 200 mg. The CYP probes will be tested before cenobamate administration, at steady state at 100mg/day of cenobamate for midazolam only and finally at steady state at 200mg/day of cenobamate for all CYP probes.

The results of this DDI study will provide a basis to make appropriate dose recommendation for a safe use of concomitant drugs with cenobamate using these isoenzymes in their metabolic pathway.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Cenobamate, midazolam and Warfarin Pill in people with Healthy, run by SK Life Science, Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 27 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Pharmacokinetic parameters AUC (time frame: bupropion (6 days), midazolam (24 hrs), omeprazole (24 hrs), warfarin (7 days)). The study lists 2 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 19 Sep 2024.
