About this study

Official title: A Single-Center, Randomized, Open-Label, Crossover Study to Assess Elements of Abuse Liability for Three Electronic Cigarettes

The purpose of this study is to measure plasma nicotine uptake parameters, physiological measures, and subjective effect measures in smokers during and following a single ad libitum use of three electronic cigarettes versus combustible cigarettes and nicotine gum.

Read the detailed description

This study will assess various elements that may provide information regarding the potential for electronic cigarettes (e-cigarettes) to be adopted by current smokers. These various elements include: a) nicotine pharmacokinetics (PK), b) physiological measures of pulse rate and blood pressure, and c) subjective effects measured by Urge to Smoke, Product Rating, Intent to Use Product Again, and Product Effects.

What is being measured

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

  3. Nicotine pharmacokinetics with respect to initiation of in-clinic IP use following a 12-hour tobacco and nicotine abstinence

    Determine time to baseline-adjusted maximum plasma nicotine concentration (Tmax)

    Measured: -5, -0.5, 3, 5, 7.5, 10, 15, 20, 30, 45, 60, 75, 90, 120, 150, 180, 240, 300, 360 minutes

  4. Subjective effects scores for Urge to Smoke (UTS) with respect to initiation of in-clinic IP use following a 12-hour tobacco and nicotine abstinence

    Score subjective effects using a numeric rating scale (NRS) to determine area under the UTS score-versus-time curve [area under the effect curve (AUEC)], minimum UTS score, and time to minimum UTS score

    Measured: -10, 5, 15, 30, 45, 60, 90, 120, 150, 180, 240, 300, 360 minutes

  5. Subjective effects scores for Intent to Use Again (IUA) with respect to initiation of in-clinic IP use following a 12-hour tobacco and nicotine abstinence

    Score subjective effects using a NRS to determine area under the positive PE score-versus-time curve (AUEC) and maximum positive PE score

    Measured: 15, 30, 45, 60, 120, 180, 240, 300, 360 minutes

  8. Subjective effects scores for negative Product Effects (PE) with respect to initiation of in-clinic IP use following a 12-hour tobacco and nicotine abstinence

    Score subjective effects using a NRS to determine area under the negative PE score-versus-time curve (AUEC) and maximum negative PE score

    Measured: 15, 30, 45, 60, 120, 180, 240, 300, 360 minutes

  9. Maximum change in pulse rate relative to baseline

    Determine the maximum change in pulse rate

    Measured: Baseline and at timed intervals over 360 minutes following initiation of IP use

  10. Change in expired carbon monoxide (ECO) relative to baseline

    Assess change in ECO from baseline following IP use

    Measured: Baseline and 35 minutes post-IP use

  11. Baseline cotinine measured pre-IP use

    Evaluate changes in baseline cotinine to assess whether subjects substantially changed their nicotine exposure during the study

    Measured: -0.5 minute only for each IP, over 5 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Own Brand Cigarette, Electronic Cigarette #1 and Electronic Cigarette #2 in people with Smoking, run by R.J. Reynolds Vapor Company 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 12 inclusion and 10 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 Jun 2018. 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?

Nicotine pharmacokinetics with respect to initiation of in-clinic investigational product (IP) use following a 12-hour tobacco and nicotine abstinence (time frame: -5, -0.5, 3, 5, 7.5, 10, 15, 20, 30, 45, 60, 75, 90, 120, 150, 180, 240, 300, 360 minutes). The study lists 11 primary outcomes in all. 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 NCT02269514, 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 4 Jun 2018.
