Participant Flow

Overall, since recruitment was initiated in March, 2012, 49 (45%) of the 109 completed phone screens resulted in a subject eligible for Intake. Of these subjects, 41 (84%) scheduled an in-person screening visit at our center.

Of the 29 subjects (73%) who attended the initial eligibility visit, 5 withdrew post enrollment (at visit), 11 were ineligible, and 13 subjects were deemed eligible.

Galantamine ER
The study will be performed using the 8mg and 16mg doses of galantamine hydrobromide-ER, which is currently marketed for the treatment of Alzheimer's disease. Galantamine ER : The study will be performed using the 8mg and 16mg doses of galantamine hydrobromide-ER, which is currently marketed for the treatment of Alzheimer's disease. The dosing regimen, which follows FDA-approved guidelines, will be an initial 4 weeks of drug run-up at the lowest 8mg daily dose, followed by an additional one week of drug run-up at the higher dose of 16mg daily.

SECONDARY outcome

Timeframe: At Baseline (Day 0), Day 35 (Day before Target Quit Day), and Day 43

Participants will complete neurocognitive test designed to test working memory and attention and are similar to computer games, in that participants will push a button in response to the pictures they see. Working memory was measured using a computerized N-back task. During the N-back, participants are instructed to remember the location of a stimulus, a grey circle that is approximately 5 cm in diameter, as it appears randomly in 8 possible locations around the perimeter of a computer screen. Stimulus duration is 200 ms, followed by an interstimulus interval (ISI) of 2800 ms. The N-back task includes 4 conditions of varying difficulty levels: the 0-back, 1-back, 2-back, and 3-back. Median reaction time to correct responses is described below. Typical responses range from 250 ms to 1500 ms.

SECONDARY outcome

Timeframe: Days 7, 14, 21, 28, 35, and 43; Baseline session

During each visit, we asked subjects to complete the Questionnaire for Smoking Urges-Brief (QSU-B). This measure is an index of urges to smoke, or cigarette craving. The subjective symptoms listed above will be assessed at the following in-person sessions: Baseline session, Days 7, 14, 21, and 28 (brief monitoring visits), Day 35 (Day before Target Quit Day), and Days 37, 39, and 43 (during the 7-day quit attempt). The range of possible scores on the QSU-B is 10-70, with higher values indicating increased urges to smoke. This range of scores represents a "total" score; there are no subscales.

Side effects of galantamine were assessed at the following in-person sessions: Baseline session, Days 7, 14, 21, and 28 (brief monitoring visits), Day 35 (Day before Target Quit Day), and Days 37, 39, and 43 (during the 7-day quit attempt). A 37-item checklist of side effects based on the product insert (e.g., Nausea, Vomiting, Diarrhea, Loss of appetite, Stomach pain, Constipation, Gastroesophageal Reflux Problems (Heartburn)) was administered to participants at all study visits after the Intake. An open-ended side effects question was also be included. Items were measured on a scale from 0 (None) to 3 (Severe). The side effect summary score (total side effects averaged from the 37 item checklist) at each visit is reported below. Each score ranges from 0 (None) to 3 (Severe).

SECONDARY outcome

Timeframe: Days 7, 14, 21, 28, 35, and 43; Baseline session

Subjects were asked to complete the Positive and Negative Affect Scale (PANAS) to assess symptoms of negative affect (the positive affect scale was not administered). This 10-item scale assesses was assessed at the following in-person sessions: Baseline session, Days 7, 14, 21, and 28 (brief monitoring visits), Day 35 (Day before Target Quit Day), and Days 37, 39, and 43 (during the 7-day quit attempt). The range of possible total scores on the PANAS negative affect scale is 10-50, with higher values indicating an increased nicotine withdrawal. This range of scores represent a "total" score; there are no subscales within the negative affect scale of the PANAS.
