Study Arms (1)

Treatment with GATS

EXPERIMENTAL

Gala Airway Treatment System (GATS)

Device: Gala Airway Treatment System

Interventions

The Gala Airway Treatment system is a device-based, energy delivery system that delivers energy to ablate soft tissue such as the airway epithelium and sub-mucosal tissue layers. The energy is delivered via a proprietary catheter through the bronchoscope.

Also known as: GATS
Treatment with GATS

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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.
  • 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.
  • Subject has an FEV1/FVC ration \< 0.7.
  • Subject has been treated with Long Acting Beta Agonists (LABAs) or Long Acting Muscarinic Antagonists (LAMAs) or both for three months or more.
  • Subject has a cigarette smoking history of at least ten packs years.
  • 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.

You may not qualify if:

  • Subject has active respiratory infection (e.g., common cold, pneumonia, MAI, tuberculosis) or COPD exacerbation within the last three months.
  • Subject has MMRC score greater than or equal to 3.
  • Subject is taking \> 10 mg of prednisolone or prednisone per day.
  • Subject has an implantable cardioverter defibrillator or pacemaker.
  • Subject has a history of cardiac arrhythmia within past two years.
  • Subject has abnormal cardiac rhythm at time of procedure.
  • Subject has history of proven lung cancer in last 5 years.
  • Subject has pulmonary nodule or cavity requiring follow-up or intervention unless proven benign and not actively infected (e.g., aspergilloma).
  • Subject has prior lung surgery, such as lung transplant, LVRS, lung implant/prosthesis, metal stent, valves, coils, bullectomy, segmentectomy, or lobectomy. Pneumothorax without lung resection is acceptable. Pleural procedures without surgery are acceptable.
  • Subject has Alpha-1-Antitrypsin (AAT) deficiency.
  • Subject has documented history of asthma diagnosed with onset \<30 years of age, clinically significant bronchiectasis or any other significant second lung disease.
  • Subject actively smoked (including tobacco, marijuana, e-cigarettes, vaping, etc.) within the last 6 months.
  • 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.
  • Subject has the inability to walk over 140 meters.
  • 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.
