Substance DependencePhase 1NCT00728897
A Healthy Volunteer Study to Investigate the Relative Bioavailability of Two Forms of GSK598809 Capsules.
A Phase 1 study testing GSK598809 new formulation and GSK598809 old formulation in people with Substance Dependence, run by GlaxoSmithKline at 1 site in United Kingdom.
Trial summary
Study to compare PK of a new 100mg capsule with four 25mg capsules. This is required because we plan to have only single capsules administered in the later phase clinical trials but we have not had a 100mg strength before. Read more about this study

About this study
Official title: An Open Label, Randomised, Single Dose, Three-way Crossover Study to Investigate the Relative Bioavailability of a 100mg Capsule Compared to Four 25mg GSK598809 Capsules and the Effect of Food on the Pharmacokinetics of the 100mg Capsule in Healthy Male and Female Volunteers.
Study to compare PK of a new 100mg capsule with four 25mg capsules. This is required because we plan to have only single capsules administered in the later phase clinical trials but we have not had a 100mg strength before. As this is a new previously untested strength we need to ensure that the PK is similar to that achieved using 4 x 25mg. The study will also assess the effect of high fat food on the PK of the 100mg capsule. The study is planned to consist of a single part , with three dosing periods, periods 1-3 consisting of 16 subjects. There will be a week wash out between each dose. In the three dosing periods subjects will either received 4x25 mg GSK598809 capsule in a fasted state, 100mg capsule in a fasted state or 100mg GSK598809 capsule in a fed state. Subjects will return to the centre for follow-up 7-14 days after the final dose. It is expected that the total duration of the study should be approximately eight weeks.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing GSK598809 new formulation and GSK598809 old formulation in people with Substance Dependence, run by GlaxoSmithKline 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 6 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 4 Aug 2017. 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?
Blood sampling over a period of 96hrs post GSK598809 dosing in the three dosing periods. (time frame: Pre-dose, 0, 0.25, 0.5, 1, 1.5, 2, 4, 6, 8. 10, 12, 16, 24, 48. 72 and 96 hours). 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 4 Aug 2017.
