Modern Nicotine Oral Product Abuse Liability

An In-Clinic Confinement Study to Assess Elements of Abuse Liability for Six Modern Nicotine Oral Products

This is a two-site, open-label, randomized, 8-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 and following ad libitum use of the study investigational products (IPs) by generally healthy smokers.

Study Overview

• Status: Completed
• Conditions: Smoking; Tobacco Use

Detailed Description

Cigarette smokers naïve to smokeless tobacco products (ST) and smokers also using ST will be recruited into this AL study to evaluate elements of AL of six modern oral nicotine products compared to combustible cigarettes (CC) and nicotine polacrilex gum. An attempt will be made for at least one-third of the study population to include smokers using ST.

Potential subjects 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 check in day (Day -1), subjects will check-in at the clinical site to complete procedures to confirm eligibility. Eligible subjects will be enrolled, randomized and confined for 10 days (9 nights). Prior to the first product acclimation period, subjects will conduct a product familiarization of three of the modern oral nicotine products. Subjects will be randomized to one of eight product use sequences (using a Williams Design) in which they will evaluate one IP in each of eight separate Test Sessions, such that each subject will evaluate eight IPs, including six modern oral nicotine products, and both a high-AL comparator (subject's usual brand [UB] cigarette) and a low-AL comparator (a commercially available nicotine replacement therapy [NRT] nicotine gum).

On Day 2 and continuing through Day 9, subjects will participate in Test Sessions that will last approximately 4 hours. 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.

On the half day prior to each respective Test Session, a Product Acclimation Period will allow subjects ad libitum use of the subsequent IP (at least two trial uses) as per randomized sequence for product acclimation prior to use in the next day's Test Session. Subjects 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.

Description

Inclusion Criteria:

1. Able to read, understand, and willing to sign an informed consent form (ICF) and complete questionnaires written in English.
2. Generally healthy males or females, 21 to 60 years of age, inclusive, at the time of consent.
3. Smokes combustible, filtered, non-menthol or menthol cigarettes, 83 mm to 100 mm in length as primary source of tobacco.
4. Smokes an average of at least 10 cigarettes per day (CPD) and inhales the smoke, for at least 6 months prior to Screening. Brief periods of abstinence due to illness, quit attempt (prior to 30 days of Screening), or clinical study participation (prior to 30 days of Screening) will be allowed at the discretion of the an investigator.
5. Smokers who also use ST products (e.g., moist snuff, snus, modern oral), and have used ST within 30 days prior to screening, will be enrolled.
6. Agrees to smoke the same UB cigarette throughout the study period. The UB cigarette is defined as the reported cigarette brand and style currently smoked most frequently by the subject.
7. Expired breath carbon monoxide (ECO) level is ≥ 10 ppm and ≤ 100 ppm at Screening and at check-in (Day -1).
8. Positive urine cotinine test (e.g., >200 ng/mL) via dipstick at Screening.
9. Response at Screening to the Fagerström Test for Nicotine Dependence (FTND) Question 1 ("How soon after you wake up do you smoke your first cigarette?") is either "Within 5 minutes" or "6-30 minutes" (Heatherton et al., 1991).
10. Willing to use the UB cigarette, Velo PLUS IPs, and Nicorette® nicotine gum during the study period.
11. Willing to abstain from tobacco and nicotine use for at least 12 hours prior to the start of each of eight Test Sessions.
12. Females must be willing to use a form of contraception acceptable to an investigator from the time of signing the ICF until End-of-Study. Examples of acceptable means of birth control are, but not limited to: a) Surgical sterilization (hysterectomy, bilateral tubal ligation/occlusion, bilateral oophorectomy, bilateral salpingectomy); b) physical barrier method (e.g., condom, diaphragm/sponge/cervical cap) with spermicide; c) non-hormone releasing intrauterine devices (IUD) or hormone-releasing IUDs (e.g., Mirena or Kyleena); d) vasectomized partner; or e) post-menopausal and not on hormone replacement therapy.
