Effect of Switching From Cigarette Smoking to THS on Systemic Endothelial Function in Subjects With Established Atherosclerotic Disease

November 14, 2024 updated by: Philip Morris Products S.A.

A 12-month, 3-group, Preference, Multi-center Study to Demonstrate the Effects of Switching From Cigarettes to Tobacco Heating System (THS) on Systemic Endothelial Function in Subjects With Established Atherosclerotic Disease

The purpose of this study is to demonstrate improvement in flow mediated dilation (FMD), a functional endpoint associated with the progression of atherosclerosis, when switching from cigarettes to the Tobacco Heating System (THS) in subjects with peripheral arterial disease (PAD) and/or coronary artery disease (CAD). The study is planned to be conducted in the US, Europe, and Asia.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The goal of this longitudinal study is to demonstrate improvement in FMD, a functional endpoint associated with the progression of atherosclerosis and a predictor of future cardiovascular (CV) events in subjects with PAD and/or CAD, when switching from cigarettes to THS. Other CV functional endpoints, or cardiovascular biomarkers of potential harm (BoPH) representative of different pathophysiologic pathways associated with increased CV risk in smokers with established atherosclerosis will be assessed. It is expected that the totality of the evidence from this study will show the potential of THS to slow down the progression of atherosclerosis, thus helping to delay a CV event, or delaying a secondary event.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No
