CSD170401: Study to Assess Elements of Abuse Liability for Three Electronic Tobacco Vapor Products During an 11-Day In-Clinic Confinement

Completed · Not applicable

Conditions studied: Smoking

In brief

This study will examine elements of abuse liability (AL) related to potential product adoption of three electronic tobacco vapor products by current smokers relative to high and low AL comparator products (usual brand cigarette and nicotine gum, respectively). Changes in subjective measures, speed and amount of nicotine uptake, and maximum changes in physiological effects during and after product use that follows a 12-hour (minimum) tobacco and nicotine abstinence period, will be determined. The electronic tobacco vapor products will not be compared to each other.

• Smokes at least 10 cigarettes per day (on average) and inhales the smoke, for at least 6 months prior to Screening. Brief periods of abstinence due to illness, quit attempt (prior to 30 days of Screening), or clinical study participation (prior to 30 days of Screening) will be allowed at the discretion of the Investigator.
• Response at Screening to Fagerström Test for Cigarette Dependence (FTCD) Question 1 ("How soon after you wake up do you smoke your first cigarette?") is either "Within 5 minutes" or "6-30 minutes."
• Willing to use UB cigarette, electronic tobacco vapor products, and Nicorette gum during the study period.
• Willing to abstain from tobacco and nicotine use for at least 12 hours prior to each Test Session.
• Females of childbearing potential must be willing to use a form of contraception acceptable to the Investigator from the time of signing informed consent until study discharge. Examples of acceptable forms of contraception include, but are not limited to, the following.
• Surgeries:
• Hysterectomy at least 6 months prior to randomization

• Transcervical sterilization at least 6 months prior to randomization
• Hormonal birth control at least 3 months prior to randomization
• Non-hormonal intrauterine device at least 3 months prior to randomization
• Double barrier methods (e.g., condom and spermicide) at least 14 days prior to randomization
• Abstinence at least 14 days prior to randomization

• Postmenopausal at least 1 year prior to randomization and have follicle-stimulating hormone (FSH) levels consistent with postmenopausal status at screening as per Investigator or designee judgment
• Agrees to in-clinic confinement of 11 days and 10 nights.

You may not qualify if…

• Presence of clinically significant or unstable/uncontrolled acute or chronic medical conditions at Screening or Day 1, as determined by the Investigator, that would preclude the subject from participating safely in the study (e.g., uncontrolled hypertension, lung disease, cardiac disease, neurological disease or psychiatric disorders) based on safety assessments such as clinical laboratory tests, medical history, and physical/oral examinations.
• History, presence of, or clinical laboratory test results indicating diabetes.
• History or presence of stomach ulcers.
• At risk for heart disease that would preclude the subject from participating safely in the study, as determined by the Investigator.
• Use of medicine for the treatment of depression, unless on a stable dose for the past 6 months prior to screening and deemed clinically stable by the PI.
• Current scheduled treatment for asthma within the past consecutive 12 months prior to screening. As needed treatment, such as inhalers, may be included at the PIs discretion pending approval from the medical monitor.
