Study summary

This is a preliminary open-label study to determine whether a medication called galantamine (Brand Name: Razadyne) will help smokers quit and whether it reduces cognitive problems that smokers experience during a quit attempt.

Read the detailed description

Galantamine, an FDA-approved treatment for Alzheimer's disease, is used to treat cognitive impairment by enhancing acetylcholine through inhibition of the enzyme, acetylcholinesterase. We propose an open-label pilot feasibility study of short-term (6 weeks) treatment with galantamine.

Sixteen chronic smokers will undergo a validated procedure for screening new medications. Following an initial 4-week drug run-up phase (8mg daily of galantamine-ER), medication dose will be increased to 16 mg daily of galantamine-ER during the fifth and sixth weeks of the study. At the beginning of Week 6, smokers will receive brief counseling and make a 7-day quit attempt.

Following completion of the study, participants will be offered standard smoking cessation treatment. Subjects will perform a working memory task (Visual/Spatial N-Back), a sustained attention task (Continuous Performance Task; CPT), a recall memory task (Word Recognition), a cognitive flexibility task (Wisconsin Card Sort Test), and a response inhibition task (Stop Signal Task). The primary outcome is the ability to remain abstinent during a 7-day quit attempt. Secondary outcomes include change in cognitive performance, adherence, and side effects.

This pilot study will provide information about the role of the cholinergic system during brief abstinence and whether enhancing acetylcholine reduces abstinence-induced cognitive symptoms that promote smoking relapse. Information obtained in this study may further establish cognitive performance measures as endophenotypes for nicotine dependence.

What researchers measure

Primary outcomes

  1. Number of Days of Abstinence During a 7-day Quit Attempt

    Participants will undergo a 6-week study medication period. Day 36 will be the beginning of a 7-day practice quit attempt, during which number of days of abstinence will be assessed.

    Time frame: Days 36-43; following a 5-week dose run-up

Secondary outcomes

  1. Cognitive Performance: Working Memory Reaction Time

    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.

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

  2. Cognitive Performance: Working Memory Accuracy

    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. Number of correct responses (true positives) is described below. The maximum number of correct responses is 60.

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

  3. Subjective Symptoms (Smoking Urges)

    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.

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

  4. Side Effects of Galantamine

    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).

    Time frame: Days 7, 14, 21, 28, 35, 37, 39, and 43; Baseline session

  5. Subjective Symptoms (Negative Affect)

    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.

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

  6. Subjective Symptoms (Nicotine Withdrawal)

    Subjects were asked to complete the Minnesota Nicotine Withdrawal Scale - Revised version (MNWS). The scale assesses eight DSM-IV items of nicotine withdrawal. The subjective symptoms listed above 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). The range of possible total scores on the MNWS is 0-60, with higher values indicating an increased nicotine withdrawal. This range of scores represent a "total" score; there are no subscales.
