Targeted Lung Denervation for Patients With Moderate to Severe COPD

A Sequential Two Phase Multicenter, Randomized Study to Optimize Dose Selection and Evaluate Safety After Treatment With the Holaira™ Lung Denervation System in Patients With Moderate to Severe COPD.

The purpose of this study is to evaluate safety of Targeted Lung Denervation (or TLD) in patients suffering from moderate to severe COPD. It is hypothesized that TLD will have a similar safety profile and improved physiological and functional outcomes to a sham-control.

A prospective, sequential two phase multicenter, randomized double-blind, safety, & feasibility study. The goal of AIRFLOW-1 will be to compare two energy doses and select the optimal energy dose to be utilized in AIRFLOW-2. The goal of AIRFLOW-2 is to compare the optimal energy dose to a sham control. All subjects will be followed for a minimum of 3 years.

Inclusion Criteria:

• Diagnosis of COPD with 30% ≤ FEV1 < 60% and FEV1/FVC <70% (post-bronchodilator);
• Patient ≥ 40 and ≤ 75 years of age at the time of consent;
• The patient has no child bearing potential or a negative pregnancy test (serum or urine), if applicable;
• Smoking history of at least 10 pack years;
• Non-smoking for a minimum of 2 months prior to consent and agrees to continue not smoking for the duration of the study;
• Participated in a pulmonary rehabilitation program or engaged in regular physical activity under professional supervision in the past 12 months;

Exclusion Criteria:

• Has been less than 6 weeks following the resolution of a COPD exacerbation or active lower respiratory infection (eg. pneumonia);
• History of recurrent respiratory infections and/or COPD exacerbations (more than 2 hospitalizations within 1 year of enrollment);
• Prior lung or chest procedure (eg. lung transplant, LVRS, BLVR, lung implant, metal stent, valves, coils, median sternotomy, bullectomy, segmentectomy, or lobectomy);
• Documented history of asthma diagnosed with onset <30 years of age, cystic fibrosis, paradoxical vocal cord motion, Churg-Strauss syndrome, allergic bronchopulmonary aspergillosis, severe interstitial lung disease or active tuberculosis;
• Pulmonary nodule requiring follow-up or intervention unless proven benign;
• Daily use of >10 mg of prednisone or its equivalent at the time of enrollment;
