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.

About this study

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.

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. The study is expected to provide insights into IDs in mechanisms and endophenotypes that contribute to smoking trajectories in YLS and thereby lead to targeted pharmacotherapy and behavioral interventions for at-risk YLS.

What is being measured

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

  1. change in smoking and salivary cotinine concentration

    Change in smoking and salivary cotinine concentration from baseline to 18 months will be assessed at 3 month intervals-- 3, 6, 9, 12, 15, and 18 months after initial assessments.

    Measured: 18 months

Secondary outcomes (1)
  1. reason for change in smoke rate

    Self-reported reasons for changing smoking or for continuing to smoke at the same rate will be assessed a 3-month intervals until 18 months after baseline assessment.

    Measured: 18 months after initial assessment

Questions about this trial

What is this clinical trial studying?

An observational study of Nicotine Dependence, run by Southern Illinois University Carbondale 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 1 inclusion and 7 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 1 Nov 2022. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

change in smoking and salivary cotinine concentration (time frame: 18 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02129387, which also lists 2 linked publications.

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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Nov 2022; AzTrials last refreshed its copy on 7 Nov 2026.
