What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Geometric mean ratio of the pharmacokinetic parameter (AUC0-t) of KW-6356 in combination with or without a perpetrator drug

    Measured: Starting just before intake of KW-6356 and continued until 168 or 336 hours after intake of KW-6356.

Secondary outcomes (8)
  1. Geometric mean ratio of the major pharmacokinetic parameters (Cmax) of KW-6356 in combination with or without a perpetrator drug

    Measured: Starting just before intake of KW-6356 and continued until 168 or 336 hours after intake of KW-6356.

  2. Geometric mean ratio of the major pharmacokinetic parameters (AUC0-∞) of KW-6356 in combination with or without a perpetrator drug

    Measured: Starting just before intake of KW-6356 and continued until 168 or 336 hours after intake of KW-6356.

  3. Pharmacokinetic parameters (tmax) of KW-6356

    Measured: Starting just before intake of KW-6356 and continued until 168 or 336 hours after intake of KW-6356.

  4. Pharmacokinetic parameters (CL/F) of KW-6356

    Measured: Starting just before intake of KW-6356 and continued until 168 or 336 hours after intake of KW-6356.

  5. Pharmacokinetic parameters (Vz/F) of KW-6356

    Measured: Starting just before intake of KW-6356 and continued until 168 or 336 hours after intake of KW-6356.

  6. Pharmacokinetic parameters (t1/2) of KW-6356

    Measured: Starting just before intake of KW-6356 and continued until 168 or 336 hours after intake of KW-6356.

  7. Plasma concentrations of a perpetrator drug

    Measured: Starting just before intake of a perpetrator drug at Day 8 and continued until 12 or 24 hours after the last dose of a perpetrator drug.

  8. Incidence of treatment-emergent adverse events

    Measured: Starting 24 hours before intake of KW-6356 and continued until 14 days after the last dose of a perpetrator drug.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing KW-6356, Clarithromycin and Rifampicin in people with Parkinson's Disease, run by Kyowa Kirin Co., Ltd. at 1 site in Japan.

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 4 inclusion and 15 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 29 Nov 2019. 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 Japan. 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?

Geometric mean ratio of the pharmacokinetic parameter (AUC0-t) of KW-6356 in combination with or without a perpetrator drug (time frame: Starting just before intake of KW-6356 and continued until 168 or 336 hours after intake of KW-6356.). 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 29 Nov 2019.
