Clinical Trial Summary

The purpose of the study is to evaluate the product use and adaptation in adult, current cigarette smoking subjects between baseline and after one month of use of one of two P3P variants. The effect of P3P use behavior on nicotine pharmacokinetic (PK) profile, acceptability, as well as the safety and tolerability of P3P over a period of 1 month will be investigated.

Description:

This is a study of daily use of up to 15 P3P products over one month, including 2 confinement periods (2 overnight stays at the beginning of the study and 1 overnight stay at the end of the exposure period). During the confinement visits, nicotine PK from P3P exposure will be assessed as well as pharmacodynamic effects related to craving, sensory parameters, product experience, and product acceptance. Between the two confinement periods, subjects will return to the investigational site for weekly ambulatory visits during which P3P will be resupplied and selected safety and other study assessments will be performed. From the start of the exposure period onwards, subjects will be instructed not to smoke or use other tobacco or nicotine containing products and to use P3P exclusively.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Plasma Nicotine Concentration-time Profile	To measure the plasma nicotine concentration-time profile following correction of baseline nicotine levels.	Derived from multiple blood sampling pre- and post-product use (over 4 hours post-product use), on day 1 and day 30.
Primary	Maximum Nicotine Concentration [cCmax]	To measure the maximum plasma nicotine concentration [cCmax] following correction of baseline nicotine levels.	Derived from multiple blood sampling pre- and post-product use (over 4 hours post-product use), on day 1 and day 30.
Primary	Time to the Maximum Nicotine Concentration [cTmax]	To measure the time to maximum nicotine concentration [cTmax] following correction of baseline nicotine levels.	Derived from multiple blood sampling pre- and post-product use (over 4 hours post-product use), on day 1 and day 30.
Primary	Area Under the Concentration-time Curve From Start of Product Use (T0) to 4 Hours [cAUC(0-4h)]	To measure the area under the plasma concentration-time curve [cAUC(0-4h)] following correction of baseline nicotine levels.	Derived from multiple blood sampling pre- and post-product use (over 4 hours post-product use), on day 1 and day 30.
Secondary	Craving for a Cigarette	Measured on a Visual Analogue Scale (VAS) of 0 (no craving) to 100 (strong craving). Over time results calculated as area under curve mm*hour.	Before, during and up to 4 hours post-product use on day 1 and day 30
Secondary	Sensory Parameters	Measured with a Sensory Questionnaire. Response to each question is assessed on a 7-point scale, ranging from 1 (not at all) to 7 (extremely).	Within 60 minutes after product use on day 1 and day 30.
