CSD190501: A Study to Determine Subject Puffing Patterns of an Electronic Nicotine Delivery System in an Ambulatory Setting

This study will be a single-center, controlled, open-label, parallel study to evaluate the puffing patterns of healthy adult consumers of tobacco products switching from a usual brand (UB) Electronic Nicotine Delivery Systems (ENDS) product to an ENDS Investigational Product (IP) product with 4.8% nicotine over a three-week ambulatory period. This study will be conducted in support of a Premarket Tobacco Product Application (PMTA) ENDS submission to the US Food and Drug Administration (FDA) Center for Tobacco Products (CTP).

Detailed Description

Potential subjects will complete a pre-screening interview and a Screening Visit to assess their eligibility and, based on meeting eligibility requirements, will be enrolled into the study on the same day of the Screening Visit.

Once enrolled, the subjects will be assigned to one of the seven flavor variants of ENDS product. Subjects will be allowed to sample flavors and determine which flavor that they would like to use for the length of the study. Subjects will then participate in a three-week ambulatory study in which they will use their assigned IP in place of their UB ENDS. Subjects will be directed to not use their UB ENDS products during the study.

At the initial visit, subjects will be provided an orientation to the product, including the IP power unit, cartridges, the Product Use and Behavior (PUB) instrument, PUB application, and a provided electronic device. Based upon their UB ENDS usage, they will be given a sufficient amount (for three weeks of ad libitum use equaling 375% of their self-reported UB weekly use) of ENDS cartridges. The study will involve a one-week acclimation period followed by a two-week product use evaluation period. At the end of the first week of the study, subjects will receive a phone call from the clinic to assess IP compliance and to ensure that they are not using their UB ENDS. The PUB instrument will collect topography data, and product use data will be uploaded frequently using a web-based PUB application installed on the electronic device provided by the Sponsor. Throughout the study, subjects will receive weekly phone calls to remind them of guidelines for using their assigned IP. Subjects will be instructed to use the IP in place of their UB ENDS, but they will be allowed to use non-ENDS tobacco/nicotine-containing products according to their normal use pattern. All used cartridges may be disposed of by the subject.

At the conclusion of the three-week ambulatory period, subjects will return to the clinic; return the IP power unit, charger, all unused cartridges, the PUB instrument (and all cables/charger), and the provided electronic device. Each subject will complete all End of Study procedures, including completing the Product Evaluation Scale (PES) questionnaire, and they will then be discharged from the study.

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 male or female, ≥21 years of age, inclusive, at the time of consent.
3. Positive urine cotinine test at Screening.
4. Cartridge-based, closed-system ENDS are the primary form of tobacco/nicotine-containing products used within 30 days of Screening. Subjects may be users of other tobacco/nicotine-containing products. If the subject is a dual/poly user of tobacco/nicotine-containing products then the subject must self report that a cartridge-based, closed-system ENDS is their primary product.
5. Must have used 2 or more ENDS cartridges per week over the last 30 days. 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 Principal Investigator (PI).
6. Females must be willing to use a form of contraception acceptable to the PI from the time of signing the ICF until the end of the study.
7. Must be willing to use the assigned IP and only the assigned flavor as their exclusive source of ENDS use for the full duration of the three-week ambulatory period. Use of other non-ENDS tobacco/nicotine-containing products will be permitted during the ambulatory period.
8. Must have familiarity with modern electronic devices such as an IOS/Android smart phone or tablet computer ("tablet") and be willing to be provided an electronic device, that allows for both Bluetooth connectivity and internet connectivity and be willing to keep both active for the length of the study.
9. Must be willing to use an application on the provided electronic device, and keep the application active for the length of the study.

Exclusion Criteria:

1. Presence of clinically significant uncontrolled cardiovascular, pulmonary, renal, hepatic, endocrine, gastrointestinal, psychiatric, hematological, neurological disease, or any other concurrent disease or medical condition that, in the opinion of the PI, makes the study participant unsuitable to participate in this clinical study.
2. History or presence of diabetes.
3. Systolic blood pressure of > 160 mmHg or a diastolic blood pressure of > 95 mmHg, measured after being seated for five minutes, with exceptions at the PI's discretion.
4. Scheduled treatment for asthma currently or within the past consecutive 12 months prior to the Screening-Enrollment Visit. As-needed treatment, such as inhalers, may be included at the PI's discretion pending approval from the Medical Monitor.
5. Any history of cancer, except for primary cancers of skin such as localized basal cell/squamous cell carcinoma that has been surgically and/or cryogenically removed.
6. Use of any medication or substance that aids in smoking cessation, including but not limited to any nicotine replacement therapy (NRT, e.g., nicotine gum, lozenge, patch), varenicline (Chantix®), bupropion (Wellbutrin®, Zyban®), or lobelia extract within (≤) 30 days prior to the signing of informed consent.
7. Participation in another clinical trial within (≤) 30 days prior to signing the ICF. The 30-day window for each subject will be derived from the date of the last study event in the previous study to the time of signing the ICF in the current study.
8. Females who have a positive pregnancy test, are pregnant, breastfeeding, or intend to become pregnant during the course of the study.
9. Individuals ≥ 35 years of age currently using systemic, estrogen-containing contraception or hormone replacement therapy.
10. A positive urine drug screen without evidence of prescribed corresponding concomitant medication(s) at Screening.
11. Postpones a decision to quit using tobacco/nicotine-containing products in order to participate in this study or a previous attempt within (≤) 30 days prior to the signing of the ICF.
12. Drinks more than 21 servings of alcoholic beverages per week or has a positive alcohol breathalyzer result at Screening.
13. Determined by the PI to be inappropriate for this study.
