- Alcohol abuse, defined as self-report of an average weekly intake of > 21 standard drinks or an average daily intake of >3 standard drinks (males) or an average weekly intake of >14 standard drinks or an average daily intake of >2 standard drinks (females) in the past 6 months. One unit is equivalent to a half-pint (220mL) of beer or one (25mL) measure of spirits or one glass (125mL) of wine. Participants will be advised to minimize alcohol consumption during the study, as there may be the potential for additive effects of study medication and alcohol, potentially causing greater sedation and feeling of intoxication than alcohol alone.

About this study
Official title: A Double-Blind, Placebo-Controlled, Parallel Group Design Trial of the Selective D3 Antagonist, GSK598809, Added to CBT and NRT for Smoking Cessation and Prevention of Very Early Relapse to Smoking
The purpose of this research study is to find out if an investigational drug, GSK598809 can help people who have very recently quit smoking; the investigators want to find out if continuing to take GSK598809 over six weeks can help prevent smokers from relapsing. To relapse means you "fall back" into smoking again after quitting. The investigators also want to find out if GSK598809 is safe to take without causing too many side effects.
Read the detailed description
We propose to conduct a first test of the effect of the dopamine D3 receptor antagonist, GSK598809, on smoking behavior when treatment is started immediately following the quit date. To do this, we propose to conduct a 10-week, double-blind, placebo-controlled, proof of mechanism study in 90 adult smokers. Participants will complete baseline evaluations. They will receive manualized cognitive behavioral therapy, beginning prior to the quit date, and will set a quit date for the day before their week 2 study visit. They will be given short acting NRT (gum or lozenge) to use on their quit date. They will be asked to arrive for the week 2 visit with 18-24 hours abstinence and an expired air CO ≤ 10ppm. Those who do so will be randomly assigned to receive double blind GSK598809 or identical placebo for six weeks. Participants will begin double blind GSK598809 or placebo, both in conjunction with prn NRT up to 8 mg per day for two weeks. Participants will then continue double blind GSK598809 or placebo in the absence of NRT for 4 more weeks. At the end of this period (week 8 of the study), participants will then be followed 2 weeks after discontinuation of double blind treatment to complete the 10 weeks of the study.

What is being measured
The primary outcome is the main question the study is designed to answer.
4-week, Continuous Tobacco Abstinence at the End of the 6-week, Double Blind, Treatment Phase
The hypothesis is that those assigned to GSK598809 will demonstrate a higher rate of biochemically-verified, 4-week, continuous tobacco abstinence than those assigned to identical placebo at the end of the 6-week, double blind, treatment phase. Four-week continuous abstinence will be defined as Timeline Followback Calendar confirmation at study visit of smoking no cigarettes in the past 7 days, and expired air CO<10ppm for 4 consecutive weeks (the last 4 weeks of the randomized phase)
Measured: Week 8 of the study
Secondary outcomes (3)
7-day, Point-prevalence Tobacco Abstinence at the End of the First Week of Exposure to GSK598809/Placebo
The hypothesis is that those assigned to GSK598809 will demonstrate a higher rate of biochemically-verified, 7-day, point-prevalence tobacco abstinence than those assigned to identical placebo at the end of the first week of exposure to GSK598809/placebo.
Measured: Week 3 of the study
7-day, Point-prevalence Tobacco Abstinence at the End of 6 Weeks Exposure to GSK598809/Placebo
The hypothesis is that those assigned to GSK598809 will demonstrate a higher rate of biochemically-verified, 7-day, point-prevalence tobacco abstinence than those assigned to identical placebo at the end of 6 weeks exposure to GSK598809/placebo.
Measured: Week 8 of the study
Number of Participants With 7-day, Point-prevalence Tobacco Abstinence 2-weeks After Discontinuation of Double Blind Study Medications
The hypothesis is that those assigned to GSK598809 will demonstrate a higher rate of biochemically-verified, 7-day, point-prevalence tobacco abstinence than those assigned to identical placebo two weeks after discontinuation of double blind study medications.
7-day, Point-prevalence tobacco abstinence was defined as not smoking for the 7 consecutive days before this visit after discontinuation of double blind study medications
Measured: Week 10 of the study

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing GSK598809 in people with Nicotine Dependence, run by Massachusetts General Hospital 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 0 inclusion and 24 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 23 Feb 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 9 Jan 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
4-week, Continuous Tobacco Abstinence at the End of the 6-week, Double Blind, Treatment Phase (time frame: Week 8 of the study). 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 23 Feb 2017; AzTrials last refreshed its copy on 7 Nov 2026.
