Attempts to quit cigarette smoking are often accompanied by negative mood and problems in
attention and memory. These effects, in turn, may contribute to smoking relapse. This
exploratory/developmental project examines the effects of a novel medication, GTS-21, on
individuals interested in smoking cessation. It is hypothesized that GTS-21 will reduce
negative affect, improve cognition and/or reduce smoking relapse in healthy adult men and
women who are chronic cigarette smokers.

women who are chronic cigarette smokers.
The project is a clinical trial assessing the effects of GTS-21 (an α7 nicotinic receptor
partial agonist) on smoking, mood, neurocognition, and neurophysiology, in a small sample of
chronic smokers who are currently healthy and interested in smoking cessation. Using a
double-blind, placebo controlled, parallel group design, 54 (27 women) community smokers who
have demonstrated a readiness to quit will participate over a 7 week active trial. Subjects
will be randomly assigned to active drug or placebo groups. Across the study period,
participants will undergo repeated neurobehavioral testing, laboratory assessments of
cardiovascular and liver function, and provide weekly updates regarding smoking behavior,
mood state and side-effects.

Inclusion Criteria:
- Minimum of 12 years of education
- Must report typical daily smoking of > 10 cigarettes/day over the previous year
- Must report a history of at least 3 years of regular smoking
- Must provide carbon monoxide measures of at least 6.5 ppm
- Must report a willingness to quit smoking
Exclusion Criteria:
- Participants engaged in behavioral and/or nicotine replacement therapies, or assisted
quit efforts, within previous 6 months.
- Must not meet criteria for other substance dependence or major psychiatric disorders.
- Must be absent chronic medical conditions that might jeopardize health and safety,
confound data interpretation or that contraindicate the administration of compounds
acting at nAChR sites. This list includes disorders with direct effects on neurologic
function (e.g., seizure disorders, transient ischemic events, chronic or active
hepatic disease), metabolic disorders (e.g., uncontrolled Type 2 diabetes), or
cardiovascular disease (e.g., hypertension, mitral valve compromise, tachycardia, or
irregular heart rates).
- Must not smoke only cigars, pipes or hookahs or use nicotine products but not
cigarettes
- Must not report current use of nicotine replacement therapies (i.e., occasions of > 4
h/week during a typical week, even if not used as a cessation aid)
- Must not have used bupropion within the previous year
- Must not report any past use (regardless of year) of varenicline
- Women may not be breastfeeding, pregnant or intending to become pregnant during the
study period
