About this trial

This is an interventional device feasibility trial for Chronic Bronchitis

Eligibility Criteria

40 Years - 75 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Subject is diagnosed with chronic bronchitis for a minimum of two years, where chronic bronchitis is defined clinically as chronic productive cough for three months in each of two successive years in a patient in whom other causes of productive cough have been excluded.
  2. Subject has GOLD Stage II chronic obstructive pulmonary disease (COPD) with a preprocedure post-bronchodilator FEV1 of greater than or equal to 30% and less than or equal to 80% of predicted within three months of enrollment.
  3. Subject has an FEV1/FVC ration < 0.7.
  4. Subject has been treated with Long Acting Beta Agonists (LABAs) or Long Acting Muscarinic Antagonists (LAMAs) or both for three months or more.
  5. Subject has a cigarette smoking history of at least ten packs years.
  6. Subject in the opinion of the site investigator is able to adhere to and undergo three bronchoscope procedures inclusive of lung biopsies and Gala treatments, and has provided a signed informed consent.

Exclusion Criteria:

  1. Subject has active respiratory infection (e.g., common cold, pneumonia, MAI, tuberculosis) or COPD exacerbation within the last three months.
  2. Subject has MMRC score greater than or equal to 3.
  3. Subject is taking > 10 mg of prednisolone or prednisone per day.

  11. Subject has documented history of asthma diagnosed with onset <30 years of age, clinically significant bronchiectasis or any other significant second lung disease.
  12. Subject actively smoked (including tobacco, marijuana, e-cigarettes, vaping, etc.) within the last 6 months.
  13. Subject has known airway colonization with resistant organisms including but not limited to pseudomonas, MRSA, B Cepacia, MTB, M abscessus, mucor or any significant fungus.
  14. Subject has the inability to walk over 140 meters.
  15. Subject has a serious medical condition, such as: uncontrolled congestive heart failure, uncontrolled angina, myocardial infarction in the past year, renal failure, liver disease, cerebrovascular accident within the past 6 months, uncontrolled diabetes, hypertension, autoimmune disease or uncontrolled gastric reflux.
  16. Subject has known sensitivity to medication required to perform bronchoscopy (such as lidocaine, atropine, and benzodiazepines).
  17. Subject is pregnant, nursing, or planning to get pregnant during study duration.
  18. Subject has received chemotherapy within the past 6 months or is expected to receive chemotherapy during participation in this study.
  19. Subject is or has been in another clinical investigational study within 6 weeks of baseline.
  20. Subject on anticoagulation for cardiovascular indications and is unable to have anticoagulants (i.e., Aspirin, Plavix, Coumadin) withheld for at least seven days prior to bronchoscopy in the opinion of the Investigator.

5. Study Description

Brief Summary
Feasibility trial (FIH) to assess the safety and clinical utility in patients with chronic bronchitis in Canada.
Detailed Description
The Gala Airway Treatment system is a device-based, energy delivery system that delivers high frequency short duration energy to the airway epithelium and sub-mucosal tissue layers. The energy is delivered via a proprietary catheter through the bronchoscope. Two sessions of treatment will be delivered one month apart. The right lung is treated at the first treatment session and the left lung is treated at the second treatment session (approximately one month after the right side is treated). Treatment will be delivered by a respiratory physician (interventional pulmonologist) in a tertiary teaching hospital during a bronchoscopic procedure. The bronchoscopy will be delivered during general anaesthesia. It is anticipated that the bronchoscopic procedure will last less than 60 minutes in total. Treatment will be deemed to have been delivered following the successful treatment during the two bronchoscopies. A third bronchoscopy will be performed three months following the second treatment session where treatment is not delivered but a cryo-biopsy will be taken from the airway sites that have been treated during the two previous bronchoscopic treatment session to evaluate the effect of the treatment on the airways producing excessive mucous. Subjects will be required to submit to several tests during the study including two CT scans (lung), respiratory function tests, exercise testing.
