About this study
Official title: A Randomised, Double-Blind, Single-Dose, Four-Period Cross-Over Study to Determine the Effects of Alcohol on the Pharmacokinetics and Pharmacodynamics of GSK1521498 in Healthy Subjects
The aim of the study is to assess the safety and tolerability of GSK1521498 in combination with alcohol and to determine the amount of GSK1521498 and alcohol in your blood after you have been given these together. The study will also determine whether GSK1521498 will have an effect on alcohol liking and consumption.
Read the detailed description
The study is to test a new drug which may be used for treating alcohol addiction. The drug works by inhibiting the effects of messenger molecules called opioids. These opioids are naturally produced within the human body, and are involved in controlling how much alcohol we drink and the pleasure we get from drinking alcohol. We believe that GSK1521498 might be effective in the treatment of alcohol addiction because it is well known that drugs working on similar binding sites in the brain reduce the pleasure we get from drinking alcohol. As alcohol can effect the way that a drug is metabolised in the body, The investigators need to determine that it is safe to take GSK1521498 in combination with alcohol. and to determine the amount of GSK1521498 and alcohol in your blood after you have been given these together. The study will also determine whether GSK1521498 will have an effect on alcohol liking and consumption.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing GSK1521498 in people with Alcoholism, run by GlaxoSmithKline 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 15 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 21 Jul 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 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. Some participants in this study may receive a placebo. 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?
Pharmacokinetic interaction (time frame: GSK1521498 PK sampling; pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 9, 12, 13, 24, 48 and 72 hr post-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 21 Jul 2017.
