Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Chronic Obstructive Pulmonary Disease (COPD) Device: Holaira™ Lung Denervation System with energy delivery Device: Holaira™ Lung Denervation System without energy delivery Phase 2

Detailed Description:
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.

Primary Outcome Measures :
  1. AIRFLOW-1: Therapeutic interventions through 3 months; AIRFLOW-2: and rate of respiratory adverse events between 3 and 6.5 months [ Time Frame: 3-6.5 months ]
    Respiratory adverse events is defined as: worsening bronchitis, worsening dyspnea, common cold, COPD exacerbation, influenza, pneumonia, respiratory infection, respiratory failure, tachypnea and wheezing. Subjects may have reported more than one type of respiratory adverse event.


Secondary Outcome Measures :
  1. Adverse events over 3 years [ Time Frame: 3 years ]
    The assessment of safety will be based on reporting of adverse events, particularly those adverse events that are respiratory in origin.

  2. Device Success [ Time Frame: 6 months ]
    Device success is defined as ability to deliver the test device to its intended locations, provide complete circumferential treatment and removal of the test device without the report of an adverse event during the procedure.

  3. Spirometry measures [ Time Frame: 3 years ]
    Measures include: FEV1, FVC, FEV1/FVC

  4. Change in Functional testing: Cycle Ergometry & 6MWT [ Time Frame: 3 years ]
  5. Heath-related Quality of Life (SGRQ-C & EQ-5D) [ Time Frame: 3 years ]
  6. Procedure Success [ Time Frame: Through discharge ]
    Procedure Success is defined as device success without the report of an adverse event through hospital discharge.

  7. Plethysmography measures [ Time Frame: 3 years ]
    Measures include Raw, TLC, IC, ITGW

  8. CT Scan assessment [ Time Frame: 3 years ]
