About this study

Official title: An Open-Label, Positron Emission Tomography Study to Assess Adenosine A2A Brain Receptor Occupancy of BIIB014 at Multiple Dose Levels in Healthy Male Volunteers

To establish the extent to which BIIB014, following 8 to 12 consecutive days of dosing at selected dose levels, occupies the brain's A2A receptors. Receptor occupancy will be assessed by PET scanning using a radiolabelled tracer.

Read the detailed description

Subjects will be enrolled sequentially into cohorts of 2 to 4 subjects. PET scan results will determine the actual number of cohorts enrolled and the BIIB014 dose given to each subject. Since all enrolled subjects will be receiving BIIB014, this study is being listed as a 1-arm, Single Group study (actual study design is dose escalation).

Participating subjects will be required to reside in the clinical unit for 10 to 14 consecutive days. Participants will receive 1 oral dose of BIIB014 daily for 8 to 12 consecutive days. During the study, subjects will undergo 2 PET scans and 1 MRI. Frequent blood sample for pharmacokinetic assessments will also be performed.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BIIB014Drug

    oral administration of BIIB014, given once daily for 8 to 12 consecutive days, at various doses as specified in protocol

  • [11C]SCH442416Other

    11C]SCH442416 is a radiolabelled tracer molecule that specifically binds to adenosine A2A sites and will be used to evaluate receptor occupancy. The target activity will be 370 MBq. [11C]SCH442416 will be administered IV as a bolus injection over 30 seconds following the start of each PET scan.

What is being measured

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

  1. PET scanning with [11C]SCH442416 of the putamen, caudate, nucleus accumbens, thalamus, and cerebellum.

    Measured: pre-dose and 24h following last dose

Secondary outcomes (1)
  1. Concentrations of BIIB014 and its N-acetyl metabolite will be measured in blood plasma

    Measured: up to 24h following last dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BIIB014 and [11C]SCH442416 in people with Healthy, run by Biogen 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 3 inclusion and 14 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 30 Jul 2008. 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?

PET scanning with [11C]SCH442416 of the putamen, caudate, nucleus accumbens, thalamus, and cerebellum. (time frame: pre-dose and 24h following last dose). 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 30 Jul 2008; AzTrials last refreshed its copy on 6 Nov 2026.
