What is being measured

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

  1. Assessment of pharmacokinetic profile of MDV3100 by Cmax (Maximum concentration)

    Measured: Day 1 through Day 53 (29 times)

  2. Assessment of pharmacokinetic profile of MDV3100 by AUCinf (AUC extrapolated to infinity)

    Measured: Day 1 through Day 53 (29 times)

  3. Assessment of pharmacokinetic profile of MDV3100 by AUC0-432h (AUC from the time of dosing to 432 hours post-dose)

    Measured: Day 1 through Day 53 (29 times)

Secondary outcomes (6)
  1. Assessment of pharmacokinetic profile of MDV3100

    tmax (Time to attain Cmax), t1/2 (Apparent terminal elimination half life), Vz/F (Apparent volume of distribution during the terminal phase after extra vascular dosing) and CL/F(Apparent total body clearance after extra vascular dosing)

    Measured: Day 1 through Day 53 (29 times)

  2. Assessment of pharmacokinetic profile of the metabolites MDPC0001 and MDPC0002

    Cmax, AUC0-432h, tmax, t1/2, and AUC0-inf

    Measured: Day 1 through Day 53 (29 times)

  3. Assessment of metabolite-to-parent ratios for MDV3100

    This may additionally be reported to assess effects on particular enzyme pathways

    Measured: Day 1 through Day 53 (29 times)

  4. Assessment of Gemfibrozil and gemfibrozil 1-O-β-glucuronide (Arm 2)

    Cmax, C0h, Cmin, tmax, AUCtau

    Measured: Day 1 through Day 53 (50 times)

  5. Assessment of itraconazole and hydroxyitraconazole (Arm 3)

    Cmax, C0h, Cmin, tmax, AUCtau

    Measured: Day 1 through Day 53 (50 times)

  6. Safety as assessed by recording adverse events, laboratory assessments, vital signs and electrocardiograms (ECGs)

    In arm 3, liver function tests (AST, ALT, GGT, total bilirubin) will be done regularly during itraconazole dosing

    Measured: Day 1 through Day 53

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MDV3100, Gemfibrozil and Itraconazole in people with Healthy Subjects and Pharmacokinetics, run by Astellas Pharma Europe B.V. at 1 site in France.

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 9 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 1 Aug 2013. 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 France. 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?

Assessment of pharmacokinetic profile of MDV3100 by Cmax (Maximum concentration) (time frame: Day 1 through Day 53 (29 times)). The study lists 3 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 NCT01913379, 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 1 Aug 2013.
