  8. T½ of S-warfarin

    Measured: Blood samples for pharmacokinetic analyses of S-warfarin will be taken at various time points from Day 1 to 7 of Treatment Period A and from Day 1 to 7 of Treatment Period B (total duration: 14 days).

Secondary outcomes (6)
  1. AUC0-144 for international normalized ratio (AUC INR)

    Measured: Blood samples for pharmacodynamic analyses of S-warfarin will be taken at various time points from Day 1 to 7 of Treatment Period A and from Day 1 to 7 of Treatment Period B (total duration: 14 days)

  2. The maximum effect on INR (INRmax)

    Measured: Blood samples for pharmacodynamic analyses of S-warfarin will be taken at various time points from Day 1 to 7 of Treatment Period A and from Day 1 to 7 of Treatment Period B (total duration: 14 days)

  3. Time to reach maximum effect of INR (t Emax)

    Measured: Blood samples for pharmacodynamic analyses of S-warfarin will be taken at various time points from Day 1 to 7 of Treatment Period A and from Day 1 to 7 of Treatment Period B (total duration: 14 days)

  4. AUC0-144 for Factor VII (AUC VII)

    Measured: Blood samples for pharmacodynamic analyses of S-warfarin will be taken at various time points from Day 1 to 7 of Treatment Period A and from Day 1 to 7 of Treatment Period B (total duration: 14 days)

  5. The maximum effect on Factor VII (VIImax)

    Measured: Blood samples for pharmacodynamic analyses of S-warfarin will be taken at various time points from Day 1 to 7 of Treatment Period A and from Day 1 to 7 of Treatment Period B (total duration: 14 days)

  6. Time to reach maximum effect of Factor VII (t Emax)

    Measured: Blood samples for pharmacodynamic analyses of S-warfarin will be taken at various time points from Day 1 to 7 of Treatment Period A and from Day 1 to 7 of Treatment Period B (total duration: 14 days)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Midazolam, Warfarin and Daridorexant in people with Healthy, run by Idorsia Pharmaceuticals Ltd. at 1 site in Germany.

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 2 inclusion and 8 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 8 Nov 2022. 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 Germany. 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?

Maximum concentration (Cmax) of midazolam and its metabolite 1-OH midazolam (time frame: Blood samples for pharmacokinetic analyses of midazolam will be taken at various time points from Day 1 to 2 of Treatment Period A, from Day 1 to 2 of Treatment Period B, and from Day 1 to 2 of Treatment Period C (total duration: 6 days).). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05480488, which also lists 1 linked publication.

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 8 Nov 2022.
