Trial summary

Smoking remains a leading cause of preventable disease and premature death worldwide. Approximately 1 out of every 5 deaths is associated with cigarette smoking, and roughly half of all daily smokers will die prematurely from tobacco-related illness. Read more about this study

About this study

Official title: Palatability of Experimental Cigarettes

Smoking remains a leading cause of preventable disease and premature death worldwide. Approximately 1 out of every 5 deaths is associated with cigarette smoking, and roughly half of all daily smokers will die prematurely from tobacco-related illness. Reducing the nicotine in cigarettes to the point that they are rendered non-addictive can potentially be an effective public policy measure that can significantly reduce tobacco-related mortality and morbidity by decreasing the initiation of smoking and promoting cessation. The Family Smoking Prevention and Tobacco Control Act (FSPTCA) enables the FDA to establish tobacco product standards including placing limits on the allowable nicotine content of cigarettes. Currently, no reduced nicotine cigarettes are available that will allow studying the feasibility of this policy measure. The National Institute on Drug Abuse has contracted with Research Triangle Institute to assist in the development of cigarettes with varying nicotine content that can be made available to researchers. They have established a contract that will result in the manufacture of 9 million cigarettes to be distributed to the research community. Prior to full production, the palatability and nicotine intake of these cigarettes in smokers must be determined.

Phase 3: This descriptive study will use a between subjects, double blind design. This study will test 3 nicotine levels of nicotine, tar and ventilation. Subjects and research assistants will be blind to the cigarette type.

What is being measured

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

  1. Change in UrineTotal Nicotine Equivalent (TNE) Between Baseline and Week 1

    Two urine TNE levels are taken, one at baseline and one at week 1, to assess TNE levels for nicotine exposure. TNE is the sum of nicotine, cotinine, trans 3'-hydroxycotinine and their respective glucuronide conjugates. Values reported in nmols/ml.

    Measured: Second Visit (Week 1) minus Baseline (Day 1)

Secondary outcomes (3)
  1. Responses on Modified Cigarette Evaluation Scale

    Modified Cigarette Evaluation Scale [CES] is a 100 mm visual analog scale (0=not at all or very little nicotine; 100=extremely or high in nicotine) of 20 questions assessing different dimensions of responses to usual brand cigarettes (e.g., psychological reward, satisfaction and aversiveness) and includes additional 5 point likert-type questions (definitely agree to definitely disagree) on perceptions of satisfaction and willingness to use the product. Results satisfaction subscale.

    Measured: Baseline usual brand cigarettes (Day 1) compared to when using study cigarettes (Week 1)

  2. Change From Baseline of Perceived Health Risk Scale Response to Test Cigarettes

    Questionnaire: Perceived Health Risk Scale asks subjects to rate their perception of health risks for lung cancer for the study product to which they have been randomly assigned. This is a 100 mm visual analog scale; 0=very low risk of disease, 100=very high risk of disease.

    Measured: Baseline (Day 1) Compared to Second Visit (Week 1)

  3. Comparison of Number of Cigarettes Smoked

    Subjects were given a daily diary to collect the number of study and/or conventional cigarettes they have smoked each day. Cigarettes smoked (both usual brand and experimental) in a given week were summed over the first 7 reported days. If the number of cigarettes smoked was missing for 1 day, the average of the other days in that week was used in its place and reported as total number of cigarettes per week.

    Measured: 1 week

Questions about this trial

What is this clinical trial studying?

A study testing Low level nicotine cigarette, Intermediate nicotine level cigarette and High level nicotine cigarette in people with Smoking, run by University of Minnesota 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 4 inclusion and 8 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 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 12 Jan 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 UrineTotal Nicotine Equivalent (TNE) Between Baseline and Week 1 (time frame: Second Visit (Week 1) minus Baseline (Day 1)). 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 NCT01568905, which also lists 1 linked publication.

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 2019.
