About this study

Official title: A Phase I, Open Label Study to Assess the Absorption, Metabolism, Excretion, and Mass Balance of a Single Dose of Oral [14C]-IDV184001AN in Healthy Adult Male Participants

The purpose of this open label study is to characterise the absorption, metabolism, excretion, and mass balance of [14C]-IDV184001AN ([14C]-IDV184001) in healthy adult male participants.

Read the detailed description

The study is designed as an open label, single-dose study in healthy adult participants for the following reasons:

  • Oral administration of IDV184001AN has demonstrated linear PK and thus [14C]IDV184001AN will be given as a single dose.
  • A comparator is not necessary for the evaluation of the objectives.
  • Blinding of the study treatment is not required as there is no comparator.
  • Conducting the study in healthy participants mitigates the potential confounding effects of the disease state and concomitant medications.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing [14C]IDV184001AN in people with Opioid Use Disorder, run by Indivior Inc. 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 7 inclusion and 32 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 13 Feb 2025. 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?

Yes. Results are posted in the registry (first posted 13 Feb 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percent of Radioactive Dose Excreted in the Urine, Feces, and Urine+Feces (%Dose) Following a Single Oral Dose of [14C]-IDV184001AN in Healthy Adult Male Participants (time frame: Pre-dose to 168 hours post-dose). The study lists 29 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 13 Feb 2025.
