About this study

Official title: An Open Label, Single-dose, Single-period Study Designed to Assess the Mass Balance Recovery, Metabolite Profile and Metabolite Identification of Carbon-14 BIA 28-6156 in Healthy Male Subjects

The study is designed to determine the absorption, distribution, metabolism and elimination (ADME) of BIA 28-6156 in humans, further explore the PK of BIA 28-6156, evaluate the extent of distribution of total radioactivity into blood cells, provide additional safety and tolerability information and collect samples for metabolite profiling and structural identification.

Read the detailed description

This is an open-label, single-dose, single period study in healthy male subjects. It is planned to enroll 6 subjects. All subjects will receive a single oral dose Carbon-14 BIA 28-6156. Blood samples will be collected at regular intervals for PK analysis, mass balance and metabolite profiling and identification from pre-dose up to 240 h post-dose. Urine and faecal samples will be collected at regular intervals for mass balance and metabolite profiling and identification from pre-dose until the mass balance criteria have been met.

What is being measured

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

  1. Mass balance recovery of total radioactivity in all excreta (urine and faeces)

    CumAe and Cum%Ae

    Measured: Urine: Day 1 through Day 11, Faeces: Day -1 through Day 11

  2. Collection of urine and faecal samples for total radioactivity

    Total radioactivity for total recovery of Carbon-14 BIA28-6156

    Measured: Urine and Faeces: Pre-dose until 288 hours post-dose

  3. Collection of plasma samples for metabolite profiling

    Collection of major metabolites for metabolite profiling of BIA28-6156

    Measured: Pre-dose until 240 hours post-dose

  4. Collection of plasma samples for structural identification

    Identification of chemical structure of major metabolites of BIA28-6156

    Measured: Pre-dose until 240 hours post-dose

  5. Collection of whole blood samples for total radioactivity

    Total radioactivity for total recovery of Carbon-14 BIA28-6156

    Measured: Pre-dose until 240 hours post-dose

Secondary outcomes (5)
  1. Determination of routes and rates of elimination of Carbon-14 BIA 28-6156

    Measured: Day 1 through Day 11

  2. Identification of the chemical structure of each metabolite accounting for more than 10% by AUC of circulating plasma total radioactivity and more than 10% of total radioactive dose

    Measured: Urine and Faeces: Day 1 through Day 11, Plasma: Day 1 through Day 7

  3. Measurement of BIA 28-6156 PK parameters

    Measured: Day 1 through Day 11

  4. Evaluation of whole blood: plasma concentration ratios for total radioactivity

    Measured: Day 1 through Day 7

  5. Adverse events (AEs)

    Measured: Screening through Day 11

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Carbon-14 BIA 28-6156 in people with Parkinson Disease, run by Bial R&D Investments, S.A. at 1 site in United Kingdom.

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 21 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 28 May 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 Kingdom. 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?

Mass balance recovery of total radioactivity in all excreta (urine and faeces) (time frame: Urine: Day 1 through Day 11, Faeces: Day -1 through Day 11). The study lists 5 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 28 May 2025.
