About this study

Official title: A Phase I, Open-Label, Randomized 3-Period Crossover Study in Healthy Male Subjects to Evaluate the Pharmacodynamic Interactions Between YM150 on Naproxen at Steady-State

The primary objective of this study is to evaluate whether naproxen and darexaban which have different effects on blood coagulation influence each other in their effects. Also it will be investigated whether the blood levels of either drug are influenced by the presence of the other drug. In addition, the safety and tolerability of each drug and the combination of the drugs will be investigated.

What is being measured

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

  1. Assessment of pharmacodynamics of naproxen

    Measured: Baseline and 3 hours after multiple dosing (darexaban: 6 days, naproxen: 4 days) of darexaban, naproxen, or a combination of the two

Secondary outcomes (4)
  1. Assessment of pharmacodynamics of darexaban

    Measured: Baseline and 3 hours after multiple dosing (darexaban: 6 days, naproxen: 4 days) of darexaban, naproxen, or a combination of the two

  2. Pharmacokinetics of darexaban assessed by plasma concentration

    Measured: Plasma samples are taken until 24 hours after six days of dosing of darexaban, or the combination with naproxen

  3. Pharmacokinetics of naproxen assessed by plasma concentration

    Measured: Plasma samples are taken until 12 hours after four days of dosing of naproxen, or the combination with darexaban

  4. Monitoring of safety and tolerability through assessment of vital signs, Electrocardiogram (ECG), clinical safety laboratory and adverse events

    Measured: 6 days (for treatment periods with darexaban) or 4 days. (naproxen alone)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing darexaban and Naproxen in people with Pharmacodynamic Interaction and Healthy Subjects, run by Astellas Pharma Inc 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 10 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 11 Apr 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 pharmacodynamics of naproxen (time frame: Baseline and 3 hours after multiple dosing (darexaban: 6 days, naproxen: 4 days) of darexaban, naproxen, or a combination of the two). 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 11 Apr 2013.
