United States45 participantsStarted 2014-05

Plain-language summary

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.

Inclusion criteria

✓. Able to read, understand, and willing to sign an informed consent form and complete questionnaires written in English.
✓. Generally healthy male or female, 21 to 60 years of age, inclusive, at Screening.
✓. Expired breath carbon monoxide (ECO) level is ≥ 15 ppm and ≤ 100 ppm at the Screening and Randomization Visits, measured between 12 p.m. and 6 p.m.
✓. Cigarettes are the only tobacco product used within (≤) 30 days of Screening.
✓. Smokes combustible, filtered, non-menthol cigarettes, 83 mm to 100 mm in length.
✓. Agrees to smoke usual brand (UB) cigarette throughout the study period. Usual brand cigarette is defined as the cigarette brand style currently smoked most frequently by the subject.
✓. 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 Fagerstrom Test for Nicotine Dependence, Question 1 ("How soon after you wake up do you smoke your first cigarette?") is either "Within 5 minutes" or "6 - 30 minutes."

Exclusion criteria

✕. Clinically significant or unstable/uncontrolled acute or chronic medical conditions at Screening, as determined by the Investigator, that would preclude a subject from participating safely in the study (e.g., uncontrolled hypertension, asthma or other lung disease, cardiac disease, neurological disease or psychiatric disorders) based on safety assessments such as clinical laboratory tests, medical history, and physical/oral examinations.
