Nicotine Pharmacokinetic Study of Heated Tobacco and Heated Herbal Products

October 19, 2023 updated by: Imperial Brands PLC

A Randomised, Cross-Over, Nicotine Pharmacokinetic and Pharmacodynamic Study of Heated Tobacco and Heated Herbal Products Compared With Combustible Cigarettes

This is a randomised, cross-over, open-label, confinement study conducted in 25 adult male or female smokers of combustible cigarettes (CCs). The study investigates combustible cigarettes, heated tobacco products (HTPs), and Heated Herbal Products (HHPs), with endpoints including pharmacokinetic evaluation, and subjective effects.

Subjects will perform a Screening Visit and one Study Visit, including a 6-day confinement period.
