Study summary

A novel type of non-cigarette tobacco product was recently approved for sale in the US, the heated tobacco product (HTP) IQOS. IQOS may be less harmful than cigarettes, and there are some reports that it may produce more rewarding subjective effects compared to e-cigarettes. The approval of IQOS provides a unique opportunity to gather preliminary data surrounding IQOS. The goal of this pilot study is to assess the subjective effects and relative reinforcement value of IQOS, including its downstream effects on cigarette smoking. Current smokers will complete a one-week baseline period where they smoke as normal before attending an in-person lab visit. During the in-person lab visit, participants (n=10) will sample a traditional cigarette and a novel IQOS tobacco product. Participants will answer questionnaires about each product they sample and then complete a preference assessment in which they choose between the IQOS and their own cigarette. Finally, participants will take home a tobacco product they sampled to use ad libitum (1-week sampling). During the at-home baseline and sampling weeks, participants will complete electronic daily diaries cataloging their tobacco use. Biomarkers (i.e., expired carbon monoxide, cotinine) will corroborate self-reported indices of use.

What researchers measure

Primary outcomes

  1. Number of Participants Who Prefer IQOS

    Participants complete a preference assessment in which they choose between the IQOS or a traditional cigarette in a series of trials. The outcome of this assessment is the number of participants who prefer the IQOS over a traditional cigarette

    Time frame: Lab Visit 2, occurring approximately one week after the initial screening/baseline visit

Secondary outcomes

  1. Cigarettes Per Day

    The average percent reduction in cigarettes per day observed in Week 2

    Time frame: Week 2 of study

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jul 2020 to primary completion in Oct 2020, 2 months.

Results were first posted in Oct 2021, 1 year after primary completion.

Of 141 non-industry interventional studies with no phase under Smoking, half reached primary completion within 38 months of starting (the median), counting those still running; a quarter within 23 and three quarters within 60. This study's 2 months is below that.

Counting every sponsor, half of 155 studies reached it within 37 months; a quarter within 18 and three quarters within 59.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 27, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
