详细描述
This study is a double-blind, randomized, placebo-controlled, parallel group, two-site study designed to assess the effects of varenicline as compared with placebo on responses to in vivo alcohol cue exposure in the human laboratory setting. After signing informed consent, subjects will be screened for eligibility including medical history, physical examination, vital signs, electrocardiogram (ECG), drinking history by the timeline follow-back (TLFB) method, alcohol breathalyzer test, Clinical Institute Withdrawal Assessment for Alcohol-revised (CIWA), medication use, MINI neuropsychiatric interview, urine toxicology screen, clinical chemistry, response to cue reactivity, and Columbia Suicide Severity Rating Scale (CSSR-S). Women of child-bearting potential will have a pregnancy test. If eligible for the study, subjects will be randomized using a stratified permuted block randomization procedure in an approximate 1:1 ratio (targeting 24 subjects per group - 12 subjects per group per site) to receive either varenicline or placebo for 6 weeks. Any nicotine use versus no use (cigarettes, cigars, chewing tobacco, electronic cigarettes, etc.) in the week before randomization is the stratification variable.
Varenicline or matched placebo will be titrated over the first week of the study up the maintenance dose of 1 mg (active) or two capsules (placebo) taken orally BID for an additional 5 weeks. Subjects will be seen in the clinic at screening, at randomization and 6 other times during the study. A final follow-up telephone interview will occur during Week 9 (2 weeks after the end of study visit).
After the first two weeks and after five weeks of investigational product administration at Study Week 3 and Study Week 6, respectively, subjects will undergo a cue reactivity paradigm session (HLAB) including 4 individual visual analog scale (VAS) items assessing alcohol craving, 2 VAS items assessing emotional reactivity to picture stimuli, and 2 items assessing emotional manipulation. Immediately after the HLAB session, subjects will view each picture again and record the emotion felt using the Self-Manikin Assessment (SAM).

干预措施: Placebo oral capsule (Drug)
结局指标
主要结局
Cue-elicited Craving
时间窗: Study Week 3
The primary outcome is cue-elicited alcohol craving, operationalized as the difference in Visual Analog Scale (VAS) craving for alcohol when exposed to an alcohol cue minus the VAS craving for alcohol when exposed to a water cue. The VAS has a minimum value of 0 and maximum value of 20; higher scores indicate more craving (a worse outcome).
次要结局
- The Percentage of Subjects Abstinent During the Last Month of Treatment (Weeks 3-6).(Weeks 3-6)
- Percent Heavy Drinking Days(Weeks 3-6)
- Cigarettes Smoked Per Week(Weeks 3-6)
- Penn Alcohol Craving Scale(Study Weeks 3, 4, 5, 6 (assessed weekly during this period))
