Status Recruiting

Clinical Trial Summary

COPD is characterized by lung injury and inflammation caused by noxious particles and gases, including those emanating from cigarette smoke and air pollution. Despite the clear detrimental impact of poor air quality on respiratory outcomes, regardless of smoking status, to investigators' knowledge, there are no studied environmental interventions targeting indoor air quality to improve respiratory health of smokers, thus ignoring a potential target for harm reduction. Investigators propose a randomized controlled intervention trial to test whether targeted reductions of multiple indoor pollutants (PM, SHS and NO2) in homes of smokers with COPD will improve respiratory outcomes. Investigators have chosen a potent, multimodal intervention (active air cleaners + Motivational intervention for SHS reduction) in order to maximize the opportunity to prove that there is a health benefit to active smokers with COPD from indoor air pollution reduction.

Clinical Trial Description

People with COPD who have higher exposure to indoor pollutants, including particulate matter (PM), second hand smoke (SHS), and nitrogen dioxide (NO2) have worse respiratory morbidity including a higher risk of exacerbations. These effects are not obscured by smoking habit. Unfortunately, despite the clear detrimental impact of poor air quality on respiratory outcomes, regardless of smoking status, to investigators' knowledge, there are no studied environmental interventions targeting indoor air quality to improve respiratory health of smokers, thus ignoring a potential target for harm reduction. Investigators propose a randomized controlled intervention trial to test whether targeted reductions of multiple indoor pollutants (PM, SHS and NO2) in homes of smokers with COPD will improve respiratory outcomes. Investigators have chosen a potent, multimodal intervention in order to maximize the opportunity to prove that there is a health benefit to active smokers with COPD from indoor air pollution reduction. After a one-month run in period in which all participants will receive smoking cessation strategies including Motivational Interviewing (MI) and nicotine replacement therapy, participants unable to quit smoking (n=120) will have 1:1 randomization to receive either 1) multi-component environmental intervention (active "high-efficiency particulate air"(HEPA) air cleaners + MI intervention for SHS reduction) or 2) sham air cleaners. Referrals to community resources for additional support will also be provided. Investigators aim to determine whether a multi-component environmental intervention (targeting PM, SHS and NO2 reduction) will improve respiratory morbidity (i.e., symptoms, quality of life, lung function and exacerbation risk) (Specific Aim #1) and intermediate outcome measures (i.e., markers of airway and systemic inflammation and oxidative stress) (Specific Aim #2) in smokers with COPD. Investigators anticipate that results from this study will inform clinical practice guidelines and health care policies aimed at reducing COPD morbidity and may have broader implications for indoor environmental recommendations for smokers with chronic disease. ;
