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

Not Applicable

Completed

• Conditions: Tobacco Use

• Registration Number: NCT04079933
• Lead Sponsor: Altria Client Services LLC

Brief Summary

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.

Detailed Description

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.

Median Change From Baseline to End of Study for Urinary Total NNAL by Study Group and Cigarette Consumption Categories	Day 8 (Visit 3) and Day 36 (Visit 7/End of Study)	Median Change from baseline to End of Study for urinary total NNAL in Test and Control groups sub-categorized by cigarette consumption categories obtained from End of Study ('Increase', 'No Change', \>50% Reduction', '50 to \<100% Reduction', '100% Reduction' and 'Missing') are presented. Baseline = Day 8 (Visit 3) values
Change From Baseline to End of Study Summary Statistics of Urinary Total NNAL (ng/g Creatinine) by Study Group and Cigarette Consumption Categories Over Visits	Day 8 (Visit 3) and Day 36 (Visit 7/End of Study)	Change from Baseline to End of Study summary statistics of urinary total NNAL (ng/g Creatinine) by Test and Control groups sub-categorized by cigarette consumption categories obtained from End of Study ('Increase', 'No Change', \>50% Reduction', '50 to \<100% Reduction', '100% Reduction' and 'Missing') are presented. Baseline = Visit 3 (Day 8) values.
Characterization of Subgroups Based on Change From Baseline in Total NNAL	Day 36 (Visit 7/End of Study) relative to the start of the baseline period (Visit 2/Day 1)	Statistical analyses on the number of subjects in subgroups based on urinary total NNAL change from baseline to the last visit are presented.; Baseline = Visit 3 values.
