About this study

Official title: An Open Label, One-sequence, Parallel Study to Compare the Single Dose Pharmacokinetics of YM178 in Healthy Poor or Extensive Metabolisers for CYP2D6 and to Assess the Effect of Multiple Doses of YM178 on the Metabolism of the Model Substrate Metoprolol

The study aims to compare blood and urine concentrations of mirabegron (YM178) in healthy poor or extensive metabolizers for CYP2D6 and to evaluate if blood levels of metoprolol change whilst being dosed at the same time with daily miragebron.

Read the detailed description

The study is an open label, single center study. All subjects are genotyped for CYP2D6 before the study. Genotype expression is confirmed by dextromethorphan phenotyping.

Part I: The pharmacokinetic profile of a single dose of YM178 is compared in 8 healthy male subjects genotyped and phenotyped as poor metaboliser (PM) for CYP2D6 and in 8 healthy male subjects genotyped and phenotyped as extensive metaboliser (EM) for CYP2D6.

Part II: The effect of YM178 on the model substrate of CYP2D6 metoprolol is evaluated, using a cross-over design, in 12 healthy male subjects genotyped and phenotyped as EM for CYP2D6.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing mirabegron and metoprolol in people with Pharmacokinetics of Mirabegron and Healthy Subjects, run by Astellas Pharma Inc at 1 site in Netherlands.

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 6 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 10 Apr 2014. 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 Netherlands. 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 mirabegron assessed by plasma concentration (time frame: Pre-dose until 72 hours after 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 NCT01478490, 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 10 Apr 2014.
