Detailed Description
This is 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 is a descriptive study, designed to gain an understanding of how changes in smoking behaviors impact AAA growth rate and disease progression. Therefore, there are no formal statistical hypotheses to be tested.
Smoking patients with AAA who did not quit smoking after their AAA diagnosis, and who are not intending to quit within the next 6 months will be screened for enrollment and randomization in the CC and IQOS arms if all other eligibility criteria are met.
Smoking patients with AAA who had completely stopped smoking and using of any other tobacco or nicotine-containing products within 2 months of their AAA diagnosis, and are still abstinent at the time of the Screening Visit and of the Baseline Visit will be screened to be enrolled in the smoking cessation (SC) arm without randomization.
