Brain Uptake of GSK1034702: a Positron Emission Tomography (PET) Scan Study

June 26, 2017 updated by: GlaxoSmithKline

An Open Label Positron Emission Tomography (PET) Study to Investigate Brain Penetration by [Carbonyl-11C] GSK1034702 in Healthy Subjects

GSK1034702 is being developed for improving cognitive impairment in diseases such as Alzheimer's disease and schizophrenia. This study will be done in healthy men to investigate how much of the study drug gets into the brain. This will be done using Positron Emission Tomography (PET).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is an open label, single dose, non-randomized PET study in healthy male subjects to ascertain if GSK1034702 is crossing the blood-brain barrier to enable it to elicit a central effect. GSK1034702 has been shown in vitro to be a substrate for human Pgp, therefore the distribution of GSK1034702 into human brain could be adversely affected. This use of PET in conjunction with radioactively labelled GSK1034702 will help ascertain the role Pgp plays in limiting brain penetration in the presence and absence of a pharmacological relevant oral non labelled dose of 5 mg. Subjects will have an MRI scan to aid definition of brain anatomy, a baseline PET scan and a post-dose PET scan. For each subject the study will consist of at least three visits; screening visit, scanning day and follow-up.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Volume of distribution of [11C]GSK1034702 at tracer and pharmacological doses.
Time Frame: Scanning day
Scanning day

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
The kinetic rate constants at tracer and pharmacological doses.
Time Frame: Scanning day
Scanning day

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
