Results

On Day 5, significant reductions in most biomarkers of exposure (BoE) relative to the combustible cigarettes (CC) group were observed after switching to heated tobacco products. No changes in BoE were observed between baseline and Day 5 in the CC group. Significantly, the magnitude of the reduction in exposure to most of the selected harmful and potentially harmful constituents (HPHCs) observed in the heated tobacco product groups was close to that observed in the stopped smoking (SS) group.

Baseline Characteristics

There was no substantial difference between any of the six groups in terms of age, sex, BMI, daily cigarette consumption, the tar values of the subject's usual brand of CC, and FTND score at screening.

Participant flow

Of the 252 participants screened, 93 subjects were enrolled into the study. During the baseline period, three subjects withdrew from the study for personal reasons or were withdrawn due to non-compliance with the randomization process. One subject who was assigned to the THP group withdrew on Day 1 for personal reasons and was excluded from the analysis because the subject did not have any BoE assessment after post-randomization. Thus, 89 subjects completed the study in accordance with
the protocol.

Adverse events

There were no AEs reported during the study.

Outcome measures

The difference of biomarkers of exposure to selected smoke constituents between the investigational groups
