About this study

Official title: A Metabolite Identification, Mass Balance, and Pharmacokinetic Study of a Single Oral Dose of [14C]-Asimadoline Followed by Twice Daily Oral Dosing of 0.5 mg Asimadoline to Healthy Adult Male Volunteers

This is an open label, single center, metabolite identification, mass balance, and PK study in healthy male volunteers.

Read the detailed description

This is an open label, single center, metabolite identification, mass balance, and PK study in healthy male volunteers. The purposes of this study is to determine the excretion of total [14C] derived radioactivity and the metabolite profile after a single oral dose of [14C] asimadoline as well as to identify and quantitate the metabolites of asimadoline in plasma, urine, and feces after single and multiple oral doses of asimadoline.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing asimadoline in people with Healthy, run by Tioga Pharmaceuticals at 1 site in United States.

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 5 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 18 Oct 2011. 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 United States. 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?

Amount of [14C]derived radioactivity in urine and feces after a single oral dose of [14C]asimadoline (time frame: up to 1 month). The study lists 2 primary outcomes in all. 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 18 Oct 2011.
