Overview

Brief Summary

The purpose of this study is to evaluate changes in exposure to selected harmful and potentially harmful constituents (HPHC) by measuring biomarkers in adult smokers who partially or completely switch from smoking cigarettes to oral tobacco-derived nicotine (OTDN) products compared to those who continue exclusive smoking cigarettes or stop using all tobacco products.

Detailed Description

This is an open label, randomized, 6 parallel-group clinical study evaluating changes in exposure to selected HPHCs, subjective effects, and product use behavior in adult smokers relative to continued smoking who are randomly assigned to continue smoking, partially or completely switch to oral tobacco-derived nicotine products, or stop using any tobacco products for 7 days.

Eligibility Criteria

Inclusion Criteria

•Voluntary consent to participate in this study documented on the signed informed consent form (ICF).
•Healthy adult males and females 21 to 65 years of age, inclusive, at Screening
•Smoking history of an average of at least 10 but no more than 30 factory manufactured combustible cigarettes daily for at least 1 year prior to Screening. Brief periods (i.e., up to 7 consecutive days) of non-smoking during the 3 months prior to Screening (e.g., due to illness or participation in a study where smoking was prohibited) will be permitted.
•Positive urine cotinine (≥ 500 ng/mL) at Screening.
•Willing to comply with the requirements of the study.
•Willing to use all test products after product trial at Check in.
•Willing and able to abstain from cigarettes from Day 1 through the End of the study.

Exclusion Criteria

•Use of any type of tobacco or nicotine containing products other than manufactured cigarettes (e.g., e vapor products, roll-your-own cigarettes, bidis, snuff, nicotine inhaler, pipe, cigar, chewing tobacco, nicotine patch, nicotine spray, nicotine lozenge, or nicotine gum) in the 7 days prior to Check in
•Self-reported puffers (i.e., adult smokers who draw smoke from the cigarette into the mouth and throat but do not inhale).
•Planning to quit smoking in the next 30 days (from Screening visit).
•History or presence of clinically significant gastrointestinal, renal, hepatic, neurologic, hematologic, endocrine, oncologic, urologic, existing respiratory diseases, immunologic, psychiatric, lymphatic, or cardiovascular disease, or any other condition that, in the opinion of the Investigator, would jeopardize the safety of the subject or impact the validity of the study results.
•Clinically significant abnormal findings on the vital signs, physical examination, medical history, ECG, or clinical laboratory results, in the opinion of the Investigator.

Outcomes

Primary Outcomes

Summary of Urine Total NNAL Amount Excreted and Absolute Change From Baseline (ng/24 Hour) by Study Group and Study Day (mITT Population)

Time Frame: Baseline (Day -1), Day 5 and Day 7

Summary of urine total 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) amount excreted (ng/24 hour) by study group on Days -1, 5 and 7, and absolute change from Baseline on Days 5 and 7 are presented. Subjects with valid sample results are included. Original Values reported as below the limit of quantitation (BLQ) were set to one-half of the lower limit of quantitation (LLOQ) (2.00 pg/mL) for summarization and statistical analysis. Baseline = Day -1. 24-hour urine collections occurred on Days -1, 5, and 7 beginning after the first morning void and any void prior to 07:00, and finished the following morning with the last void collected at approximately 07:00 (including first morning void). Absolute change from baseline was calculated as: Post Randomization Value - Baseline Value

Summary of Urine Total NNAL Amount Excreted Percent Change From Baseline (%) by Study Group and Study Day (mITT Population)

Time Frame: Day 5 and Day 7

Summary of urine total 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) amount excreted percent change from Baseline (%) is presented. Subjects with valid sample results are included. Original Values reported as below the limit of quantitation (BLQ) were set to one-half of the LLOQ (2.00 pg/mL) for summarization and statistical analysis. Baseline = Day -1. 24-hour urine collections occurred on Days -1, 5, and 7 beginning after the first morning void and any void prior to 07:00, and finished the following morning with the last void collected at approximately 07:00 (including first morning void). % change from Baseline = (Post Randomization Value - Baseline Value) / Baseline Value x 100 %
