|Condition or disease||Intervention/treatment||Phase|
|COPD Smoking Tobacco Use||Other: THS use Other: Cigarette Other: Smoking Abstinence||Not Applicable|
This study will be a multiregional (Europe, U.S., and Asia) multi-center, open-label study with 3-group, parallel preference design (Cigarette, THS use, and Smoking Abstinence).
Subjects will self-select their group allocation according to their preference. Subjects who would like to quit cigarettes or THS during the study will be encouraged to do so and will be referred to appropriate services.
The study will be declared successful if a slowing of the disease progression is demonstrated with the primary objective endpoint of forced expiratory volume in the first second (FEV1) post-bronchodilator at Month 36 or if an improvement of COPD symptoms (COPD Assessment Test total score at interim analysis at Month 12) is demonstrated.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||1895 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||A multiregional (Europe, U.S. and Asia) multi-center, open-label study with 3-group, parallel preference design (Cigarette, THS use and Smoking Abstinence).|
|Masking:||None (Open Label)|
|Official Title:||A 3-year, 3-group, Preference, Multi-center Study to Demonstrate the Slowing of Disease Progression When Switching From Cigarette Smoking to the Tobacco Heating System (THS) in Mild to Moderate Chronic Obstructive Pulmonary Disease (COPD) Subjects With a History of Chronic Bronchitis Symptoms.|
|Actual Study Start Date :||December 16, 2022|
|Estimated Primary Completion Date :||September 2025|
|Estimated Study Completion Date :||June 2027|
Active Comparator: THS
Subjects who are not willing to quit smoking.
Other: THS use
Subjects who are not willing to quit smoking during the study duration will switch from cigarettes to using THS
Other Name: Tobacco Heating System 3.0
Active Comparator: Cigarette
Subjects who are not willing to quit smoking.
Subjects who are not willing to quit smoking during the study duration will continue smoking their own preferred brand of commercially available cigarettes.
Active Comparator: Smoking Abstinence
Subjects who are willing to quit smoking.
Other: Smoking Abstinence
Subjects who are willing to quit smoking may be prescribed an NRT to support them in remaining abstinent from use of any tobacco and nicotine containing products during the study. (Behavioral support will be provided to subjects to aid with abstinence.)
- Disease Progression [ Time Frame: At month 36 ]Disease progression will be assessed by measuring Forced Expiratory Volume in 1 second (FEV1), post-bronchodilator
- COPD symptoms [ Time Frame: At month 12 ]COPD symptoms will be assessed from the total score of the COPD Assessment Test (CAT).
