Nicotine Pharmacokinetic Profile and Safety of the Tobacco Heating System 2.2 (THS 2.2)

A Single-center, Open-label, Randomized, Controlled, Crossover Study to Investigate the Nicotine Pharmacokinetic Profile and Safety of Tobacco Heating System 2.2 (THS 2.2) Following Single Use in Smoking, Healthy Subjects Compared to Conventional Cigarettes and Nicotine Nasal Spray.

The primary objective of this clinical study is to evaluate the pharmacokinetic (PK) profile (rate and amount of nicotine absorbed) following a single use of the THS 2.2 compared to the PK profiles from a single use of a conventional cigarette (CC) and from a single use of nicotine nasal spray (NNS).

Inclusion Criteria:

• Subject is Caucasian
• Smoking, healthy subject as judged by the Investigator.
• Subject has smoked at least 10 commercially available non menthol CCs per day (no brand restrictions) for the last 4 weeks.
• Subject has smoked for at least the last 3 consecutive years.
• Subject does not plan to quit smoking in the next 3 months.

Exclusion Criteria:

• As per Investigator judgment, the subject cannot participate in the study for any reason (e.g., medical, psychiatric, and/or social reason).
• Subject has received medication within 14 days or within 5 half-lives of a drug (whichever is longer) which has an impact on CYP2A6 activity.
• Female subject is pregnant or breast feeding.
• Female subject does not agree to use an acceptable method of effective contraception.
