A Randomised, Cross-Over, Nicotine Pharmacokinetic and Pharmacodynamic Study of Heated Tobacco Products Compared to Combustible Cigarettes
Study Details
Study Description
Brief Summary
This is a randomised, cross-over, open-label, confinement study conducted in 24 adult male or female smokers of combustible cigarettes. The study investigates combustible and heated tobacco (HT) products in a cross-over design, including pharmacokinetic evaluation, subjective questionnaire assessments, as well as safety evaluation.
Subjects will perform a screening visit and a 5-day confinement period.

Outcome Measures
Primary Outcome Measures
- Nicotine Cmax [5 minutes pre-study product use and at 2, 4, 6, 8, 10, 15, 30, 45, 60, 120, and 240 minutes following the start of study product use]
Maximum measured plasma nicotine concentration
- Nicotine AUCt [5 minutes pre-study product use and at 2, 4, 6, 8, 10, 15, 30, 45, 60, 120, and 240 minutes following the start of study product use]
The area under the concentration time curve for nicotine, from time 0 to the last observed non-zero concentration
Secondary Outcome Measures
- Smoking urges Emax [10 minutes prior to the start of the product use session, and at 4, 8, 15, 45, 60, 210 and 240 following the start of study product use minutes]
The maximum change from baseline Visual Analog Scale (VAS) score (VASpre-use - VASpost-use). Subjects answer the question "How strong is your urge to smoke right now?" on a VAS: from Not at all on the left (0%) to Extreme on the right (100%).
