Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This study will be ambulatory, with subjects in cohorts 1-7 attending a total of 4 clinic visits (one every approximately 30 days) over a period of 3 months. Subjects in cohorts 1-7 will be confined in the study site overnight the night before their Day 1 (Visit 1, baseline) and Day 90 (Visit 4) visits. The Day 30 (Visit 2) and Day 60 (Visit 3) visits will be non-residential visits for pregnancy testing (female subjects) and product usage assessments and resupply only. Subjects in cohort 8 will attend the clinic for Visit 1 and Visit 4 only, and will be confined in the clinic overnight the night before each of these visits. In addition, all subjects will attend a Screening Visit.
Smokers will be asked to continue smoking their usual brand (UB) cigarettes until randomization (cohorts 1-6) or enrollment (cohort 7) at Visit 1. Never-smokers will be asked to continue not to use any tobacco or nicotine products for the entire study duration.
All subjects will be confined on Visit 1 and will use their UB cigarettes ad libitum during this period (unless required to abstain for specific tests and excluding cohort 8, who will not use any nicotine or tobacco products). Exhaled breath, 24-hour urine and blood samples will be collected and evaluated for baseline BoE and BoPH. Smokers of non-menthol UB cigarettes will then be randomized to cohort 1, 5 or 6; smokers of mentholated UB cigarettes will be randomized to cohort 2, 3, 4 or 6; smokers who intend to quit smoking will be enrolled to cohort 7; and never-smokers will be enrolled to cohort 8.
All subjects will be confined on Visit 4. Subjects in cohorts 1-6 will use their assigned product exclusively, ad libitum during this period (unless required to abstain for specific tests). Other than subjects in cohort 7 who are using nicotine replacement therapy as part of their smoking cessation strategy, subjects in cohorts 7 and 8 will not use any tobacco or nicotine products. Exhaled breath, 24-hour urine and blood samples will be collected and evaluated for BoE and BoPH.
