About this study

Official title: An Open-label, One-sequence Study to Evaluate the Effect of Multiple Doses of Rifampicin on the Pharmacokinetics of YM150 (Darexaban) and Metabolites in Young Healthy Male Subjects

The primary objective of this study is to determine the effect of rifampicin on the way the body handles darexaban and its metabolites (drug degradation products). The secondary objective of the study is to evaluate the safety and tolerability of a single dose of darexaban alone and when administered together with rifampicin.

Read the detailed description

This is an open-label, 1-sequence study in young healthy male subjects to evaluate the effect of multiple daily doses of rifampicin on the PK of darexaban and metabolites after a single dose of darexaban. In addition, safety and tolerability of darexaban administered alone and in combination with rifampicin is evaluated. Eligible subjects are admitted to the clinical unit in the morning of Day -1.

Subjects receive a single dose of darexaban on Day 1. Subjects then receive rifampicin once daily (qd) on Days 4-14.On Day 11, the second single dose of darexaban is given in combination with rifampicin.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing darexaban and Rifampicin in people with Pharmacokinetics of Darexaban and Metabolites 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 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 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?

Pharmacokinetics of darexaban and its metabolites assessed by plasma concentration (time frame: Plasma samples are taken until 72 hours after darexaban dosing). 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 NCT01406002, 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 11 Apr 2013.
