Brief Summary:
This is a pilot study on the impact of switching from cigarettes to Electronic Cigarettes (EC) on disease-related clinical symptoms and biomarkers of harm in smokers with preexisting Chronic Obstructive Pulmonary Disease (COPD). The researchers hypothesize that the smokers who switch to EC completely or significantly will experience reduced COPD symptoms, risks of exacerbations, and decreased levels of oxidative stress and inflammation.

Condition or disease Intervention/treatment Phase
Chronic Obstructive Pulmonary Disease Other: NJOY e-cigarette Not Applicable

Detailed Description:

Smokers with COPD have a higher pack-year history and nicotine dependence compared to regular smokers as exemplified by the relatively large proportion of patients diagnosed with COPD that continue to smoke (95%).

This is a translational project which addresses the changing profile of tobacco product use in the United States (US) and the need for data regarding toxicity pathways for new nicotine products such as EC. In particular it focuses on critical scientific and clinically relevant gaps relating to oxidants in EC and their potential long-term cardiopulmonary effects. The study will obtain new information regarding the potential cardiopulmonary toxicity resulting from exposure to EC-derived oxidants that may lead to long-term disease development.

Primary Outcome Measures :
  1. Cigarettes per day [ Time Frame: 12 months ]
    Self reported cigarettes per day

  2. Number of exacerbations [ Time Frame: 12 months ]
    Number of COPD exacerbations

Secondary Outcome Measures :
  1. Lung function tests (spirometry) [ Time Frame: 12 months ]

  2. COPD Assessment Test (CAT) scores [ Time Frame: 12 months ]
    8-item scale with range of scores from 0-40. Higher scores denote a more severe impact of COPD on a patient's life.

  3. 6-min walk distance (6MWD) [ Time Frame: 12 months ]
    This test measures the distance that a patient can quickly walk on a flat, hard surface in a period of 6 minutes.

  4. Tobacco exposure [ Time Frame: 12 months ]
    Measure by cotinine (ng/ml)
