About this study

Official title: The Use of Low-Dose Galantamine to Potentiate the Attention-Enhancing Effects of Low-Dose Nicotine

The aim of this study is to test whether the attention-enhancing effects of low-dose nicotine can be enhanced by the drug galantamine, FDA-approved for the treatment of Alzheimer's disease. This proof-of-principle study is performed in healthy non-smokers and involves two single exposures to a nicotine patch (7 mg/24 hrs) and two single exposures to galantamine (4 mg). The dose of galantamine is substantially lower than the clinical dose range of 16-24 mg/day. The hypothesis is that performance-enhancing effects of nicotine are greater in the presence of this low dose of galantamine.

Read the detailed description

Healthy non-smokers will be screened for study eligibility and receive training on three different attention tasks. Over four test session, participants will then perform these tasks after receiving (1) a placebo patch and a placebo capsule, (2) a nicotine patch (7 mg/24 hrs) and a placebo capsule, (3) a placebo patch and a galantamine capsule, and (4) a nicotine patch and a galantamine capsule. The four test session are performed on separate days and take approximately 7 hours each. During the first 5 hours, the participant may read or watch TV while nicotine and/or galantamine are being absorbed. During the last two hours, the participant will perform the attention tasks on a computer. The investigators hypothesize that performance-enhancing effects of nicotine, which were documented in previous research, will be larger in the presence than in the absence of galantamine. This proof-of-concept would have implications for the development of drugs for the treatment of conditions such as Alzheimer's disease or schizophrenia.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Spatial Attentional Resource Allocation Task Predictive Trials Reaction Time

    The task requires detecting brief target stimuli presented at one of four locations in the four corner of the screen. On predictive trials, a central cue predicts the target location.

    Measured: 45 min

  2. Rapid Visual Information Processing Task Hit Rate

    The task requires following a stream of digits and detecting three consecutive odd or even numbers. The Hit Rate reflects the percentage of all target sequences that were detected.

    Measured: 30 min

  3. Change Detection Task Accuracy

    The task requires encoding the color of 1 or 5 shape items and reporting whether or not one of the items changed color. Accuracy refers to the percentage of all trials in which a correct response was given.

    One participant's data were excluded from this task because of excessive no-response trials.

    Measured: 15 min

  4. Spatial Attentional Resource Allocation Task (SARAT) Non-predictive Trial Reaction Time

    The task requires responding to brief target stimuli presented randomly in one of four locations in the four corners of the screen. On non-predictive trial, the cue does not provide any advance information about where the target will occur.

    Measured: 45 min

  5. Rapid Visual Information Processing Task Reaction Time

    The task requires the detection of three consecutive odd or three consecutive even digits in a stream of sequentially presented digits.

    Measured: 30 min

  6. Change Detection Task Reaction Time

    The task requires encoding the color of 1 or 5 shape items and reporting whether or not one of the items changed color.

    One participant's data were excluded from this task because of excessive no-response trials.

    Measured: 15 min

Secondary outcomes (1)
  1. Profile of Mood Scale - Total Mood Disturbance

    Participants rate their current subjective state on a list of adjectives, which contribute to six factors/subscales. "Total Mood Disturbance" is a composite measure, obtained by summing the scores of all subscales, each with a range of 0-4, weighting the one positively valenced factor negatively. Thus, smaller or more negative values represent a more positive mood state. The theoretical range of the "Total Mood Disturbance" measure is from -4 to +20.

    Measured: 5 min

Questions about this trial

What is this clinical trial studying?

A study testing Nicotine patch and galantamine capsule in people with Basic Science Study of the Mechanisms of Attentional Enhancement by Compounds Acting on the Nicotinic Receptor, run by University of Maryland, Baltimore 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 5 inclusion and 18 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 4 Nov 2019. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does the primary outcome measure?

Spatial Attentional Resource Allocation Task Predictive Trials Reaction Time (time frame: 45 min). The study lists 6 primary outcomes in all. 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?
