A Study to Evaluate Changes in Smokers Using An Oral Tobacco-Derived Nicotine Product

The purpose of this study was to estimate changes in biomarkers of exposure (BOE) in adult cigarette smokers using an oral tobacco-derived nicotine (OTDN) product relative to adult smokers who continue smoking exclusively.

This was a randomized, controlled, open-label, parallel group, multicenter, 9-week study to determine changes in BOE in adult smokers allowed ad libitum use of an OTDN product relative to adult smokers who were not allowed to use an OTDN product. This study was conducted in adult smokers who were considered to be in overall good health. Subjects were randomized to Test (allowed OTDN use) or Control (not allowed OTDN use) groups.
