In Brief

A clinical study evaluating IQOS, Cigarette, and 1 other intervention for Smoking and 2 related conditions. Completed, enrolled 48 participants across 13 sites.

Detailed Summary

The purpose of this study was to evaluate the reduction of the Abdominal Aortic Aneurysm (AAA) annual growth rate in patients who switched from smoking cigarettes to using IQOS as compared to patients who continued to smoke cigarettes, and to patients who had quit smoking. The study also aimed to provide context to the scale of reduction in the growth rate, by comparing the AAA annual growth rates for continuing to smoke and switching to IQOS with the AAA annual growth rate in smokers who had stopped smoking. The study further evaluated the effects of switching to IQOS on co-morbidities observed in AAA patients that are related to smoking as well as to assess the effects on relevant Biomarkers of Potential Harm (BoPH) linked to smoking related diseases.
