This is a single-site, open-label, randomized, 4-way cross-over study designed to evaluate elements of abuse liability (AL) including subjective effects and 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.
Smokers who only use filtered menthol or non-menthol cigarettes and who also use loose or pouched moist snuff smokeless tobacco [Smokeless Tobacco (MST)] will be recruited into this AL study to evaluate elements of AL of two modern oral nicotine products (hereinafter, Study IPs) compared to combustible cigarettes (CC) and moist snuff tobacco.
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 5 days (4 nights).
Participants will be randomized to a product use sequence (using a Williams Design) in which they will evaluate one IP in each of four separate daily Test Sessions, such that each participant will evaluate four IPs; Product B-A 9 mg, Product C-B 9 mg, participant's usual brand moist snuff tobacco [UB MST], and a high-AL comparator (participant's usual brand [UB] cigarette).
On Day 2 and continuing through Day 5, participants will participate in daily Test Sessions that will last approximately 8 hours, consisting of a 1-hour first use session immediately followed by a 7-hour ad libitum session. 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. Following each test session, used IP (MO and UB MST pouched IPs only) will be collected, stored at -20°C, and shipped to a laboratory of the sponsor's choosing. For participants whose UB MST is loose moist snuff tobacco, 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 ab libitum period will commence. Both types of PD (subjective and physiological) and PK measures will be measured during the 7-hour ab libitum period. The number, time, and duration of use of IPs that participants request will be recorded; every used IPs (MO and UB MST pouched IPs only) will be collected, stored at -20°C, and shipped to a laboratory of the sponsor's choosing. For participants whose UB MST is loose moist snuff, a fresh unopened tin/can will be weighed immediately prior to the participant self-selects the amount of loose UB MST for their test session, then the lid will be replaced to the can/tin and weighed to the nearest 0.01g. It is permissible to use the tin/can that was used for the earlier test session.
On the half day prior to each respective Test Session, a Product Acclimation Period will allow participants ad libitum use of the subsequent IP (at least two trial uses), except the participant's UB CC and UB MST, as per randomized sequence for product acclimation prior to use in the next day's Test Session. Participants can also use their UB cigarettes ad libitum, until the 12-hour tobacco and nicotine abstinence period begins prior to each Test Session, as long as the minimum use requirement for randomized IP is met. Used IP (only MO IPs and UB moist pouched snuff) from each of the Product Acclimation periods will be collected, 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-ups after study discharge.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
