This is an interventional basic science trial for Smoking Read More

General Inclusion Criteria:

• Patient diagnosed with AAA (infrarenal, fusiform type) with a current aortic maximum minor-axis diameter of 30 to ≤ 49 mm (in male patient) and 30 to ≤ 44 mm (in female patient).
• Patient has smoked on average at least 10 commercially available CC per day (no brand restrictions) for at least 5 years prior to AAA diagnosis, based on self-reporting
• Patient is ready to comply with the study protocol (e.g., to use their assigned product/regimen during the course of the study)

Inclusion criteria specific to patients screened for enrollment and randomization to the CC or IQOS arm:

• Patient has smoked on average at least 10 commercially available CC per day (no brand restriction) for the last 12 months, based on self-reporting. Intermittent attempts to quit smoking not exceeding 2 months or short-term interruption of smoking up to 10 days within the last 12 months will be allowed. Smoking status will be verified based on a urinary cotinine test (i.e., cotinine ≥ 200 ng/mL).
• Not intending to quit smoking within the next 6 months.

Inclusion Criteria specific to patients screened for enrollment into the SC arm:

• Patient had completely quit smoking and stopped the use of any other tobacco or nicotine-containing products within 2 months after AAA diagnosis, and is still abstinent at Screening and at Baseline. Smoking status will be verified based on a urinary cotinine test (i.e., cotinine < 100 ng/mL).

Exclusion Criteria:
