A Consumer Use Behavior Study to Evaluate Puffing Topography and Average Daily Consumption of Heated Tobacco Products

Overview

This is a parallel design cohort consumer use study to measure the puffing topography of two HTP devices, with three variants of HTP consumables ("sticks,"), collectively referred to as the study investigational products (Study IP), among a sample of n=198 primary users of combustible cigarettes at a central location testing (CLT) facility in the United Kingdom (UK). Puffing topography at the CLT will be measured using a desktop puffing analyzer device (PA1). In addition to puffing topography measurements at the CLT, a tobacco product perceptions and intentions survey will be used to assess study participants' intent to purchase the Study IP, their risk perceptions, and their intended use behaviors. Participants' demographic characteristics (including age and biological sex), and tobacco- and nicotine-containing products (TNPs) use history will be collected using self-reported questionnaires. Following completion of the CLT, a subset (n=100) of the originally enrolled population will participate in a 5-day home use testing (HUT) period in which they will use the Study IP for 5 days in their everyday environments to assess average daily consumption (ADC) and usage patterns of the Study IP, as well as use of any other TNPs, recorded in a daily survey. On completion of the last day of the HUT, participants will complete a final end of study survey assessing product liking, purchase intent, and intended use behaviors.

This is a parallel design cohort consumer use study to measure the puffing topography of two HTP devices (glo and glo plus), with three variants of HTP consumables ("sticks," under the brand name "virto"), collectively referred to as the study investigational products (Study IP), among a sample of n=198 primary users of combustible cigarettes at a central location testing (CLT) facility in the United Kingdom (UK).

On completion of the last day of the HUT, participants will complete a final end of study survey assessing product liking, purchase intent, and intended use behaviors. To account for respondent drop-out, the fieldwork team will recruit approximately 15% more participants for the CLT and approximately 20% more participants to the HUT phase.
