Post-Market Surveillance of Tobacco Products

Smoking, Tobacco Clinical Trial

Official title: Post-Market Surveillance of Tobacco Products: A Multicenter Clinical Trial of Natural Adopters of Cigarettes, Moist Snuff, Camel SNUS, and Dual Use

Status Completed

Clinical Trial Summary

This is a multicenter, post market surveillance study designed to evaluate biomarkers of tobacco exposure and effect, health status measurements, and tobacco product usage patterns in subjects who are natural adopters of cigarettes and/or smokeless tobacco. Non tobacco users will serve as a non use comparison group. This study is unblinded by necessity due to the very different visual appearance of the subject's Usual Brand (UB) of tobacco product(s).

Clinical Trial Description

A total of approximately 320 subjects will be enrolled in parallel in one of the following 6 cohorts based on tobacco usage:

• Exclusive moist snuff users (n=50)

• Exclusive Camel SNUS users (n=50)

• Dual users of Camel SNUS and cigarettes (n=50)

• Dual users of moist snuff and cigarettes (n=50)

• Exclusive cigarette smokers (n=40 males and 20 females)

• Non tobacco users (n=40 males and 20 females)

The study duration will be 5.5 weeks or less, depending upon the study procedures required for the subject's specific cohort. The study duration includes screening up to 35 days prior to clinic check in (Day 1) and a 2 day confinement period of approximately 24 hours (Day 1 and Day 2). Subjects will be discharged in the morning on Day 2.

At the Initial Screening Visit, clinical study staff will perform screening assessments. Tobacco users will be instructed to provide a sufficient supply of their UB product(s) for use during pre-clinic procedures (i.e., pre-clinic used tobacco product collections) and for use during clinic confinement.

Prior to checking in for clinic confinement, subjects will return to the clinic for a Pre-Enrollment Outpatient Visit to assess enrollment eligibility related to the safe completion of triplicate spirometry and to pick up used tobacco product collection kits and/or urine collection containers for pre-clinic collection procedures. Within 14 days prior to clinic admission, subjects will be instructed, depending on their tobacco cohort, to continue smoking and/or using Camel SNUS or moist snuff at their normal rates and to collect their used cigarette butts (1 day collection) and/or used snus pouches (7 day collection), and retain the labeled snuff containers (1 day usage). Subjects will turn in their used tobacco product collections upon clinic check in.

Subjects will report to the clinical research unit in the morning on Day 1 for baseline testing, confirmation of continued study eligibility, check in of their UB tobacco product(s), and return of their urine collection containers and used tobacco product collections. Subjects will be allowed to use their UB tobacco product(s) ad libitum; tobacco products will be stored by clinic staff and will be dispensed subsequent to subject request, as allowed during scheduled study procedures (i.e., questionnaires, spirometry, carboxyhemoglobin, 6MWT [six-minute walk test]). Each UB product usage will be recorded. At approximately 2200, fasting (from all food and drink except water) and tobacco abstention will begin. Subjects must agree to remain abstinent for approximately 8-10 hours and until all Day 2 fasting procedures (i.e., samples for biomarkers of tobacco effect and exposure) have been completed. ;
