EEG & Behavioral Predictors of Changes in Smoking Trajectories in Young

Status Completed

Clinical Trial Summary

The purpose of the proposal is to identify new predictors of smoking progression in young light smokers (YLS: 18-25 years & cpd < 5) using an 18-month longitudinal design and to relate these predictors of progression to the genetic profile most highly associated with smoking progression. A number of novel predictors will be assessed in 128 YLS. Predictors will include individual differences (IDs) in EEG, reward sensitivity, attentional performance, and mood during abstinence and in response to standardized and to self-selected acute nicotine doses (ANIC), as well as genetically influenced affective traits, and smoking history. The associations of a compelling genetic functional variant polymorphism, rs16969968, in the alpha5 nicotinic receptor subunit will also be related to smoking progression and the novel predictors. The study is expected to provide insights into IDs in mechanisms and predictors that contribute to smoking trajectories in YLS and thereby lead to targeted pharmacotherapy and behavioral interventions for at-risk YLS.

Clinical Trial Description

The purpose of the proposal is to identify new biobehavioral endophenotypes that predict smoking progression in young light smokers (YLS: 18-25 years & cpd < 5) using an 18-month longitudinal design and to relate these endophenotypes and progression to the genetic profile most highly associated with smoking progression. A number of novel predictors will be assessed in 128 YLS. Predictors will include individual differences (IDs) in EEG, reward sensitivity, attentional performance, and mood during abstinence and in response to standardized and to self-selected acute nicotine doses (ANIC), as well as genetically influenced affective traits, and smoking history. The associations of a compelling genetic functional variant polymorphism, rs16969968, in the alpha5 nicotinic receptor subunit will also be related to smoking progression and the novel predictors.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
