Brief 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.
Detailed Description:
This was a controlled, open-label, 3-arm parallel group, multi-center study in patients diagnosed with Abdominal Aortic Aneurysm (AAA) to evaluate the AAA annual growth rate in adult smokers randomized to either continue smoking combustible cigarettes (CC) or to switch to IQOS and in adults who had stopped smoking, as a non-randomized control arm.
This was a descriptive study, designed to gain an understanding of how changes in smoking behaviors impact AAA growth rate and disease progression. Therefore, there were no formal statistical hypotheses to be tested.
Smoking patients with AAA who did not quit smoking after their AAA diagnosis, and who were not intending to quit within the next 6 months were screened for enrollment and randomization in the CC and IQOS arms if all other eligibility criteria were met.
Smoking patients with AAA who had completely stopped smoking and using any other tobacco or nicotine-containing products within 2 months of their AAA diagnosis, and were still abstinent at the time of the Screening Visit and of the Baseline Visit were screened to be enrolled in the smoking cessation (SC) arm without randomization.
