About this study
Official title: An In-Clinic Confinement Study to Assess Elements of Abuse Liability of Four Modern Oral Nicotine Products
This is a single-site, open-label, randomized, 6-way crossover study designed to evaluate elements of abuse liability (AL) including subjective effects, physiological measures (pharmacodynamics [PD]), and plasma nicotine uptake (pharmacokinetics [PK]) during controlled monitored use and following ad libitum use of the study investigational products (IPs) by generally healthy smokers who are also users of smokeless tobacco.
Read the detailed description
Smokers who only use filtered menthol or non-menthol cigarettes and who also use loose or pouched moist snuff smokeless tobacco [Moist Snuff Tobacco (MST)] will be recruited into this AL study to evaluate elements of AL of four modern oral (MO) nicotine products (hereinafter, Study IPs) compared to combustible cigarettes (CC) and MST.
For this study, participant's usual brand smokeless tobacco product needs to be moist snuff (loose or pouched) and not a Snus smokeless oral tobacco product.
Potential participants will complete a pre-screening telephone interview. They will complete a Screening Visit to assess their eligibility within 45 days prior to check-in and enrollment.
Starting on Day 1, participants will check-in at the clinical site to confirm eligibility. Eligible participants will be enrolled, randomized and confined in the clinic for 7 days (6 nights).
Participants will be randomized to a product use sequence (using a Williams Design) in which they will evaluate one IP in each of six separate daily Test Sessions, such that each participant will evaluate a total of six IPs; Wintergreen 12 mg nicotine (fleece A), Wintergreen 9 mg nicotine (fleece A),Wintergreen 9 mg (fleece B), Watermelon Mint 9 mg nicotine (fleece A), participant's usual brand moist snuff tobacco [UB MST], and a high-AL comparator (participant's usual brand cigarette [UB CC]).
On Day 2 and continuing through Day 7, participants will participate in daily Test Sessions that will last approximately 8 hours, consisting of a 1-hour controlled first use period immediately followed by a 7-hour ad libitum period. Each Test Session will include collection of both types of PD measures (subjective and physiological) and PK measures prior to, during, and following IP use. During each test session, used IP will be collected, and either disposed of (UB CC and loose UB MST) or stored (modern oral IP and pouched UB MST) at -20°C, and shipped to a laboratory of the Sponsor's choosing. For participants whose UB MST is loose MST, a fresh unopened tin/can will be weighed immediately prior to the 'first use' portion of the session before the participant self-selects the amount of loose MST for their initial IP use. The lid will be replaced on the can/tin and weighed to the nearest 0.01g.
Immediately following the 1-hour 'first use' portion of the test session, a 7-hour ad libitum use period will commence. Both types of PD (subjective and physiological) and PK measures will be measured during the 7-hour ad libitum use period. The number, time, and duration of use of IPs that participants request will be recorded; every used IPs (MO and pouched UB MST IPs only) will be collected, stored at -20°C, and shipped to a laboratory of the sponsor's choosing. For participants whose test session IP is loose UB MST, a fresh unopened tin/can or the tin/can used for the initial 1-hour 'first use' session will be weighed immediately prior to the participant self-selects the amount of loose UB MST for their ad libitum test session, then the lid will be replaced to the can/tin and weighed to the nearest 0.01g. After the participant's completion of the 7-hour ad libitum test session, the tin/can of UB MST will be weighed to the nearest 0.01g to determine the total amount of UB MST used during the 7-hour and the entire 8-hour test sessions.
During the remaining ~4 hours of the day following each 8-hour Test Session, a Product Acclimation Period will allow participants ad libitum use of the subsequent day's Test Session assigned MO IP (at least two trial uses; minimum acclimation use requirement), followed by use of their UB CC and UB MST ad libitum, until the 12-hour tobacco and nicotine abstinence period begins. If the participant's UB CC or UB MST are assigned per randomized sequence for use in the next day's Test Session, no (MO) product acclimation is required and participants can use their UB CC and UB MST ad libitum, until the 12-hour tobacco and nicotine abstinence period begins. Used IP (only MO IPs and pouched UB MST) from each of the MO Product Acclimation and/or end of day ad libitum use periods will be collected immediately after use, stored at -20°C, and shipped to a laboratory of the sponsor's choosing.
Safety will be monitored throughout the study by the Principal Investigator (PI) (or designee) by assessing adverse experiences/events (AEs), vital sign measurements, physical examinations (including an oral examination), and clinical laboratory tests.
The Medical Monitor will be available for consultation during the study and for any follow-up needs after study discharge.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a single-site, open-label, randomized, 6-way crossover study designed to evaluate elements of abuse liability (AL) including subjective effects, physiological measures (pharmacodynamics [PD]), and plasma nicotine uptake (pharmacokinetics [PK]) during controlled monitored use and following ad libitum use of the study investigational products (IPs) by generally healthy smokers who are also users of smokeless tobacco.

Participants will be randomized to a product use sequence (using a Williams Design) in which they will evaluate one IP in each of six separate daily Test Sessions, such that each participant will evaluate a total of six IPs; Wintergreen 12 mg nicotine (fleece A), Wintergreen 9 mg nicotine (fleece A),Wintergreen 9 mg (fleece B), Watermelon Mint 9 mg nicotine (fleece A), participant's usual brand moist snuff tobacco [UB MST], and a high-AL comparator (participant's usual brand cigarette [UB CC]).
On Day 2 and continuing through Day 7, participants will participate in daily Test Sessions that will last approximately 8 hours, consisting of a 1-hour controlled first use period immediately followed by a 7-hour ad libitum period. Each Test Session will include collection of both types of PD measures (subjective and physiological) and PK measures prior to, during, and following IP use. During each test session, used IP will be collected, and either disposed of (UB CC and loose UB MST) or stored (modern oral IP and pouched UB MST) at -20°C, and shipped to a laboratory of the Sponsor's choosing. For participants whose UB MST is loose MST, a fresh unopened tin/can will be weighed immediately prior to the 'first use' portion of the session before the participant self-selects the amount of loose MST for their initial IP use. The lid will be replaced on the can/tin and weighed to the nearest 0.01g.
Immediately following the 1-hour 'first use' portion of the test session, a 7-hour ad libitum use period will commence. Both types of PD (subjective and physiological) and PK measures will be measured during the 7-hour ad libitum use period. The number, time, and duration of use of IPs that participants request will be recorded; every used IPs (MO and pouched UB MST IPs only) will be collected, stored at -20°C, and shipped to a laboratory of the sponsor's choosing. For participants whose test session IP is loose UB MST, a fresh unopened tin/can or the tin/can used for the initial 1-hour 'first use' session will be weighed immediately prior to the participant self-selects the amount of loose UB MST for their ad libitum test session, then the lid will be replaced to the can/tin and weighed to the nearest 0.01g. After the participant's completion of the 7-hour ad libitum test session, the tin/can of UB MST will be weighed to the nearest 0.01g to determine the total amount of UB MST used during the 7-hour and the entire 8-hour test sessions.
During the remaining ~4 hours of the day following each 8-hour Test Session, a Product Acclimation Period will allow participants ad libitum use of the subsequent day's Test Session assigned MO IP (at least two trial uses; minimum acclimation use requirement), followed by use of their UB CC and UB MST ad libitum, until the 12-hour tobacco and nicotine abstinence period begins. If the participant's UB CC or UB MST are assigned per randomized sequence for use in the next day's Test Session, no (MO) product acclimation is required and participants can use their UB CC and UB MST ad libitum, until the 12-hour tobacco and nicotine abstinence period begins. Used IP (only MO IPs and pouched UB MST) from each of the MO Product Acclimation and/or end of day ad libitum use periods will be collected immediately after use, stored at -20°C, and shipped to a laboratory of the sponsor's choosing.
Safety will be monitored throughout the study by the Principal Investigator (PI) (or designee) by assessing adverse experiences/events (AEs), vital sign measurements, physical examinations (including an oral examination), and clinical laboratory tests.
The Medical Monitor will be available for consultation during the study and for any follow-up needs after study discharge.
