CSA (Chronic Bronchitis) - Clinical Trial
What is the Purpose of this Study?
We are doing this study to find out what effects (good or bad) the study device (RejuvenAir) may have on people with chronic bronchitis.
This device uses a cryospray (liquid nitrogen) that will go directly into the airways for the treatment of chronic bronchitis.
Who Can Participate in the Study?
-Men and Women, age 40-80
-Have had chronic bronchitis for 2 years or more
-Have previously smoked, but not currently
-Do not have asthma
-Have been treated for breathing problems in the past year
What is Involved?
If you choose to join this study, you will:
-Have a physical exam to make sure it is safe for you to join
-Be randomized (2 out of 3 will be in Group 1) to Group 1 or Group 2
---Group 1 will get the study cryospray during a bronchoscopy
---Group 2 will have a mock bronchoscopy that will not have the cryospray
Both groups will:
-Have 2 bronchoscopies, 30 – 60 days apart
-Fill out a daily diary about your breathing symptoms and quality of life
* If you were in the mock cyrospray group we will give you the opportunity to receive the cryospray after the study.
