Nicotine Pharmacokinetics From Research Electronic Nicotine Delivery System S-TA-U001 in Smokers and E-Cigarette Users

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

To better understand the PK and associated pharmacodynamic (PD) responses produced by the Research ENDS S-TA-U001 product, this study will compare the Research ENDS S-TA-U001 to * The subject's own brand combustion (non-menthol) cigarette and a U.S. FDA approved smoking cessation product, the NICORETTE Inhalator, in current non-menthol cigarette smokers who have some limited e-cigarette experience (Group 1). * Commercially available products in current primarily e-cigarette users (experienced ENDS users) (Group 2) The PK/PD session for each product will be conducted in a controlled clinical setting with frequent PK sampling after 14 hours of supervised abstinence from all forms of nicotine. Subjects will familiarize themselves with the Research ENDS S-TA-U001 and NICORETTE Inhalator by using each product in the real world for one day before the PK/PD session for that product. Primary Objectives: Group 1 objectives are to characterize the nicotine PK profile (eg, maximum plasma concentration \[Cmax\], time to maximum plasma concentration \[Tmax\], area under the concentration-time curve \[AUC\], and terminal half-life \[t1/2\]) for 10 inhalation and ad lib sessions of Research ENDS S-TA-U001 and explore how the Cmax compares to a 15 ng/mL level during the 4.5-minute 10 inhalation and the 6 hour ad lib use sessions, to compare the PK profiles between Research ENDS S-TA-U001 to the profiles of combustion cigarettes measured at the baseline session, and to demonstrate superiority of PK profile of Research ENDS S-TA-U001 to that of the marketed NICORETTE Inhalator. Group 2 objectives are to characterize the nicotine PK profile of Research ENDS S-TA-U001 and explore how the Cmax compares to a 15 ng/mL level during the 4.5-minute 10 inhalation and 6 hour ad lib use sessions, and to compare the PK profile between Research ENDS S-TA-U001 to the profile of a commercial ENDS product measured at the baseline session. Secondary objectives: Secondary objectives include comparison of the nicotine PK of the Research ENDS S-TA-U001 to the subjects' normal nicotine source (combustion cigarettes for Group 1 or commercial ENDS for Group 2), to evaluate the safety and tolerability of Research ENDS S-TA-U001, to evaluate the effects on craving and user satisfaction of the Research ENDS S-TA-U001 vs a combustion cigarette or the NICORETTE Inhalator (Group 1) or a commercial ENDS product (Group 2), and to evaluate various biomarkers following use of each test product.
