Summary

This study is designed to evaluate the abuse liability of very low nicotine cigarettes compared to nicotine gum and usual brand cigarettes

Detailed description

This study will be a randomized, two-part, 3-way crossover designed to evaluate the abuse liability, pharmacokinetics (PK), and product use behavior associated with study products, including VLN cigarettes, subjects' own-brand cigarettes, and nicotine polacrilex gum in healthy adult male and female exclusive smokers. Subjects will participate in a standard Screening visit and one 7-day Confined Assessment Phase, which will include a product trial session (Day -1), and two study parts (Part A and Part B). Following the Screening visit, eligible subjects will check-in to the study site on Day -1. Following the polacrilex gum training session, subjects will be required to abstain from nicotine- and tobacco-containing products for approximately 20 hours until the first product use session on Days 1 to 3; use of other nicotine-containing products will be prohibited throughout the study. No additional tobacco or nicotine products will be provided after the second product use on Days 4 to 6. On Day 1, subjects will be randomized to one of three product sequence groups in Part A, which will consist of an ad libitum product use session for each of the following study products for 4 hours in a randomized crossover manner (Days 1 to 3; one product per day): Product A: VLN cigarette Product B: Own-brand filtered standard king size cigarette Product C: 4 mg Nicotine polacrilex gum A pharmacodynamic measure ("use product again" Visual Analog Scale (VAS)) will be administered at the end of each ad libitum product use period. Product use behaviors (i.e., number of units consumed,duration of gum in mouth) will be collected throughout each ad libitum product use period. Upon completion of Part A, subjects will be randomized to one of three product sequence groups in Part B, which will consist of 3 study days (Days 4 to 6), with one product per day. Each study day will consist of: 1) Controlled Product Use Session (10 puffs from their own-brand cigarette or VLN cigarette \[maximum 3 ± 2 seconds per puff\] at approximately 30 ± 5-second interpuff intervals, or chew the nicotine polacrilex gum using the "chew and park" method for 10 minutes); and 2) Uncontrolled Product Use Session (ad libitum use for 10 minutes). The Controlled Product Use Session and Uncontrolled Product Use Session will be separated by approximately 6 hours. During Part B, pharmacodynamic measures, PK, and product use behavior (Uncontrolled only) will be collected at various time points each day.
