Details and patient eligibility

About

This study is designed to evaluate plasma nicotine pharmacokinetic (PK) parameters following the use of nicotine pouches in cigarette smokers who have experience with use of smokeless tobacco (SST) [e.g., snus, moist snuff].

Full description

Potential subjects will complete screening procedures to assess their eligibility within 45 days prior to enrollment, randomization and confinement.

Following the Screening Visit, eligible subjects will be scheduled for a Day 1 Check-in visit to complete procedures to confirm eligibility. Eligible subjects will be enrolled and begin confinement at the clinical site for 10 days and 9 nights. In addition, on Day 1, subjects will use at least one nicotine pouch (7 mg nicotine) but no more than 3 pouches to familiarize themselves with the investigational product (IP). Subjects will participate in separate Test Sessions for plasma nicotine PK assessment, one for each IP. Each Test Session will last for approximately 3 hours following the start of the IP use, and will include collection of plasma samples for PK assessments prior to, during, and following IP use.

Safety will be monitored throughout the study by the Principal Investigator (PI) (or designee) by assessing adverse events (AEs), vital sign measurements, physical examinations (including an oral examination), and clinical laboratory tests. Mandatory physical and oral examination will be performed as part of end of study or early termination procedures.

The clinical site will attempt to contact all subjects who used at least one IP (including subjects who terminate the study early) using their standard procedures approximately 7 days after the last IP use to determine if any AE has occurred since the last study visit. A return visit may be scheduled for follow-up assessments at the discretion of the PI or an appropriately qualified designee.

  2. Generally healthy males or females, 22 to 65 years of age, inclusive, at the time of consent.

  3. Body mass index (BMI) within 18.0 to 40.0 kg/m2, inclusive (minimum weight of at least 50.0 kg) at Screening.

  4. Healthy, as determined by no clinically significant medical history, physical examination, 12-lead ECG, vital signs, or laboratory (including hematology, clinical chemistry, urinalysis, and serology) findings at Screening, as judged by the PI or designee.

  5. Smoke combustible, filtered, non-menthol or menthol cigarettes, 83 mm to 100 mm in length as the primary source of tobacco use.

  6. Self-reported use of smokeless tobacco (ST) products (e.g., moist snuff, snus) at least 1 to 2 times in the subject's lifetime prior to screening.

  7. Smokes an average of at least 10 cigarettes per day (CPD) and inhale the smoke, for at least 1 year 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 PI or designee.

  8. Agrees to smoke the same usual brand (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.

  9. Expired breath carbon monoxide (ECO) level is ≥ 10 ppm and ≤ 100 ppm at Screening and at Check-in.

  10. Positive urine cotinine test (≥ 200 ng/mL) at Screening.

  11. Willing to use the IPs during the study period.

  12. Willing to abstain from tobacco and nicotine use for at least 12 hours prior to start of each of nine Test Sessions.

  13. If female and of non-childbearing potential, must meet one of the following criteria:

    1. Surgically sterile (i.e., has undergone complete hysterectomy, bilateral oophorectomy, or tubal ligation/occlusion); or
    2. In a menopausal state (at least 1 year without menses), as confirmed by follicle stimulating hormone levels (≥ 40 mIU/mL).

  14. If female and of childbearing potential, must agree to use one of the accepted contraceptive regimens from at least 30 days prior to the first administration of the IP during the study, and for at least 30 days after the last dose of the study medication. An acceptable method of contraception includes one of the following:

    1. Abstinence from heterosexual intercourse;
    2. Non-hormonal releasing intrauterine device;
    3. Use of a double barrier method (e.g., condom and spermicide) during the study and for at least 30 days after the last dose of the study medication;
    4. For females of < 35 years old only: Hormonal releasing intrauterine device; or
    5. For females of < 35 years old only: Hormonal contraceptives (e.g., oral/transdermal patch/injectable/implant hormonal birth control products).

  15. Agrees to an in-clinic confinement of at least 10 days (9 nights).

  16. Must be willing to comply with the requirements and restrictions of the study.

Exclusion criteria

  2.

  3. History, presence of, or clinical laboratory test results indicating diabetes.
  4. Scheduled treatment for asthma currently or within the past consecutive 12 months prior to the Screening Visit. As-needed treatment, such as inhalers, may be included at the PI or designee discretion pending approval from the Medical Monitor.

  9. Systolic blood pressure of > 160 mmHg or a diastolic blood pressure of > 95 mmHg, measured after being seated for five minutes at Screening and at Check-in.
  10. History of severe allergic reaction (including anaphylaxis) to any substance, previous status asthmaticus, food allergies/intolerances/restrictions (including mint, wintergreen or spearmint flavoring), or special dietary needs which, in the judgment of the PI or designee, would contraindicate the subject's participation in the study.
