Clinical Trial Summary

The purpose of the present study is to examine the pharmacokinetics and pharmacodynamics of "tobacco-free" oral nicotine pouches, at various doses and flavors, in healthy adult smokers. The study will utilize a within-subjects, double-blind design. Upon enrollment, participants will complete 7 dosing conditions: tobacco-flavored pouch (low or high nicotine dose), mint/menthol-flavored pouch (low or high nicotine dose), and fruit-flavored pouch (low or high nicotine dose); participants will also complete a condition where the participants will smoke participants' preferred brand of cigarettes. In each experimental session, participants will complete 2 product-use bouts. In bout 1, the participants will use a single product (pouch or cigarette) for a fixed period under controlled conditions. In bout 2, participants will be given 2 hours to use participants' assigned product ad libitum.


Description:

The purpose of the present study is to examine the pharmacokinetics and pharmacodynamics of "tobacco-free" oral nicotine pouches, at various doses and flavors, in healthy adult smokers. The study will utilize a within-subjects, double-blind design.

In each experimental session, participants will complete 2 product-use bouts. In bout 1, the participants will use a single product (pouch or cigarette) for a fixed period under controlled conditions. In bout 2, participants will be given 2 hours to use participants' assigned product ad libitum. Blood specimens will be obtained throughout the sessions to characterize the pharmacokinetics of nicotine and various pharmacodynamic outcomes (subjective drug effects, tobacco withdrawal symptoms, vital signs) will also be assessed. These procedures will be completed 7 separate times (on separate visits) by each participant (sessions will be separated by at least 48 hours).

Outcome

Type Measure Description Time frame Safety issue
Primary Pharmacokinetics of nicotine as assessed by the Cmax Blood plasma samples will be collected and sent to a designated laboratory for quantitative analysis of nicotine. Maximum concentration (Cmax), is the highest plasma nicotine concentration reached during a session and provides important insight into the abuse liability of a tobacco product. Up to 6.5 hours
Primary Pharmacokinetics of nicotine as assessed by the AUC Blood plasma samples will be collected and sent to a designated laboratory for quantitative analysis of nicotine. Area under the curve (AUC), represents the total nicotine exposure during an entire session and provides important insight into the abuse liability of a tobacco product. Up to 6.5 hours
Primary Subjective ratings of "Like Drug Effect" as assessed by the Drug Effect Questionnaire The DEQ will be used to obtain subjective ratings of "like drug effect". Score range from 0 (none) to 100 (extreme) using a 100mm line anchored with none/extreme designation. 6.5 hours
Primary Subjective ratings of "Pleasant Drug Effect" as assessed by the Drug Effect Questionnaire The DEQ will be used to obtain subjective ratings of "pleasant drug effect". Score range from 0 (none) to 100 (extreme) using a 100mm line anchored with none/extreme designation. 6.5 hours
Primary Subjective ratings of "take again" as assessed by the Drug Effect Questionnaire The DEQ will be used to obtain subjective ratings of "take again". Score range from 0 (none) to 100 (extreme) using a 100mm line anchored with none/extreme designation. 6.5 hours
Primary Subjective ratings of "urge to smoke" as assessed by the Hughes-Hatsukami Withdrawal Questionnaire The HHWS will be used to obtain subjective ratings of "urge to smoke". Score range from 0 (none) to 100 (extreme) using a 100mm line anchored with none/extreme designation. 6.5 hours
Primary Subjective ratings of "craving to smoke" as assessed by the Hughes-Hatsukami Withdrawal Questionnaire The HHWS will be used to obtain subjective ratings of "craving to smoke". Score range from 0 (none) to 100 (extreme) using a 100mm line anchored with none/extreme designation. 6.5 hours
Secondary Pharmacokinetics of nicotine as assessed by the Tmax Blood plasma samples will be collected and sent to a designated laboratory for quantitative analysis of nicotine. Time to maximum concentration (Tmax), is the time (in minutes) to reach Cmax. This is another measure relevant for abuse liability. Up to 6.5 hours
Secondary Tobacco withdrawal symptoms as assessed by the Tiffany-Drobes QSU brief-Factor 1 The QSU-brief factor 1 (intention to smoke) measures tobacco withdrawal symptoms using 5 items; scores are summed to produce a single score ranging from 0 to 30 6.5 hours
Secondary Tobacco withdrawal symptoms as assessed by the Tiffany-Drobes QSU brief-Factor 2 The QSU-brief factor 2 (anticipation of relief) measures tobacco withdrawal symptoms using 5 items; scores are summed to produce a single score ranging from 0 to 24 6.5 hours
Secondary Topography as assessed by the total time of use During the 2 hour ad libitum bout, topography will be collected. The total time of use (out of 2 hours) will be assessed. 2 hours
Secondary The Direct Effects of Nicotine Scale (DENS) The DENS will assess nicotine-specific effects. Scores range from 0 (none) to 100 (extreme) using a 100mm line anchored with none/extreme designation. 6.5 hours
Secondary Perceived strength of effects as assessed by the Drug Effect Questionnaire The DEQ will assess subjective ratings for "feel drug effect". Scores range from 0 (none) to 100 (extreme) using a 100mm line anchored with none/extreme designation. 6.5 hours
Secondary Negative and aversive effects as assessed by the Drug Effect Questionnaire The DEQ will assess subjective ratings for "dislike drug effect". Scores range from 0 (none) to 100 (extreme) using a 100mm line anchored with none/extreme designation. 6.5 hours
