Nicotine Pharmacokinetic and Pharmacodynamics Profile, Safety and Tolerability of P3L

A Single-center, Open-label, Ascending Nicotine Levels Study to Investigate the Nicotine Pharmacokinetic and Pharmacodynamics Profiles, Safety and Tolerability of P3L in Smoking Healthy Subjects in Relation to Nicorette® Inhalator

The purpose of this study is to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD, i.e., subjective effects) profiles, and the safety and tolerability of the nicotine-containing aerosol delivered by Platform 3 Liquid (P3L) system at three different nicotine levels in smoking healthy subjects in relation to Nicorette® inhalator.

The entire study will last between 16 to 49 days per subject. This includes :

• a screening period of up to 4 weeks prior to admission,
• 1 day of admission (Visit 2): after all inclusion/exclusion criteria are checked, all eligible subjects will be enrolled and perform a product test, first with P3L (at nicotine dose levels of approximately 50 μg/puff) and subsequently with Nicorette® inhalator (3 to 5 inhalations for each product).
• 4 days of on-site product use (one day with Nicorette® inhalator [Visit 3] and three days with P3L [Visit 4, Visit 5 and Visit 6]),
• 1 to 3 days between each product use and
• a 7-day safety follow-up period (discharge + 7 days), during which there are no scheduled investigational visits, and during which adverse events (AEs) and serious adverse events (SAEs) can be spontaneously reported by the subjects and the follow-up of AEs/SAEs will be conducted by the study investigational site.

Subjects will come to the investigational site the night before each assessment day, at least 12 hours prior to the product use, on Visit 4, Visit 5, and Visit 6. Subjects will stay overnight at the investigational site between the admission visit (Visit 2) and Visit 3. Smoking or use of any tobacco/nicotine-containing products or electronic cigarettes, apart from product use assigned on the assessment days, will not be allowed during their stay at the investigational site. Smoking will be allowed once the subjects have left the investigational site.

The maximum concentration of nicotine (Cmax) and the area under the concentration-time curve from start of product use to the last quantifiable time point (AUC0-last) will be derived from multiple blood sampling pre- and post-product use, and corrected for baseline nicotine concentration.

Inclusion Criteria:

• Subject is Caucasian
• Smoking, healthy subject as judged by the Investigator
• Subject smoked at least 10 commercially available non-menthol cigarettes (CCs) per day for the last 4 weeks
• Subject has smoked for at least the last 3 years prior to screening
• 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 donated or been in receipt of whole blood or blood products within 3 months prior to Admission Visit
• Female subject is pregnant or breast feeding
• Female subject does not agree to use an acceptable method of effective contraception
• Female subject uses estrogen-containing hormonal contraception or hormone replacement therapy
