Smoking Clinical Trial - Japanese Post-Market Cohort Study

Status Active, not recruiting

Clinical Trial Summary

The objectives and endpoints of this study will be analyzed in the study population of adults legally authorized to buy tobacco products. The study will describe the patterns of use of tobacco and nicotine containing products and self-reported health outcomes and health related events in CC (Cigarette) smokers and IQOS users in Japan.

Note: The initial study record (posted to ClinicalTrials.gov) included a clinical sub-study designed to estimate population level differences in the biomarkers of exposure and clinical risk endpoints between iQOS users, CC smokers and never-smokers. However, due to low recruitment and retention of subjects, the clinical sub-study was terminated in May 2017 and the main study was terminated in March 2018. The study protocol was updated to remove the clinical sub-study objectives. This version of the study reflects the latest version of the updated study protocol.

Clinical Trial Description

This is a prospective, observational, open cohort study of adults, legally authorized to purchase tobacco products in Japan. The study will describe the patterns of use of tobacco and nicotine containing products and self-reported health outcomes in CC smokers and IQOS users.

For IQOS users, the date of initiation of IQOS use is the trigger for all study assessments in the study. However the process will be different for CC smokers for whom assessment timing will be based on the date of enrollment. IQOS users will be enrolled into the study at least two months after initiating use of IQOS (to ensure adoption of IQOS), but less than 12 months after initiating use of IQOS. The study assessments will start at the next appropriate study time point after enrollment.

As this study is observational by design and is conducted in a post-market setting, adverse event (AE) reporting will follow the Sponsor's established post-market Safety Surveillance Procedures for spontaneously reported events. IQOS users will be reminded of the product quality complaints (including AEs) hotline that is available for all IQOS consumers in Japan. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
