A Multicenter, Prospective Trial of the IAB in Adults Suffering From COPD/Emphysema

NCT ID: NCT05087641

Last Updated: 2025-08-03

Basic Information

• Recruitment Status: ACTIVE_NOT_RECRUITING
• Clinical Phase: NA
• Total Enrollment: 20 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2022-05-03
• Study Completion Date: 2027-01-31

Brief Summary

The Pulmair Implantable Artificial Bronchus (IAB) is a device intended for implantation into the diseased bronchi of emphysema patients. The IAB is indicated for bronchoscopic treatment of adults with Chronic Obstructive Pulmonary Disease (COPD)/emphysema to relieve hyperinflation and allow bidirectional ventilation of the affected lobes.

The objective of this trial is to demonstrate a suitable benefit/risk profile to support a subsequent trial of the safety and effectiveness of the IAB to achieve its intended purpose.

The trial will enroll 24 subjects implanted with IAB(s), at no more than three study centers.

4. Body Mass Index (BMI) less than 30 kg/m2

5. 6-minute walk Distance between 100 meters and 500 meters at baseline exam

6. Stable disease with less than 10 mg prednisone (or equivalent) daily

7. Non-smoking for 4 months prior to screening interview

8. FEV1 between 15% and 50% of predicted value at baseline exam

9. FEV1/Forced Vital Capacity (FVC) < 70%

10. RV > 175%

11. mMRC score ≥ 2

Exclusion Criteria

1. Currently participating in another clinical study

2. Women of child-bearing potential

3. More than 2 COPD exacerbation episodes requiring hospitalization in the last year at screening

4. Any COPD exacerbations within 6 weeks of planned intervention

5. Two or more instances of pneumonia episodes in the last year at screening

6. Clinically significant mucus production or chronic bronchitis

7. Myocardial Infarction or unstable / uncontrolled congestive heart failure within 6 months of screening

8. Prior lung transplant, Lung Volume Reduction Surgery (LVRS), bullectomy or lobectomy

9. Clinically significant bronchiectasis

10. Unable to safely discontinue anti-coagulants or platelet activity inhibitors for 7 days

11. Uncontrolled pulmonary hypertension (systolic pulmonary arterial pressure > 45 mm Hg) or evidence or history of cor pulmonale as determined by recent echocardiogram (completed within the last 3 months prior to screening visit)

12. Suspected pulmonary nodule or lung cancer

13. High Resolution Computed Tomography (HRCT) collected per CT scanning protocol within the last 6 months of screening date and evaluated by clinical site personnel using 3D segmentation software shows:

1. Large bullae encompassing greater than 30% of either lung

2. Insufficient landmarks to evaluate the CT study using the software as it is intended

3. All lobes are less than 25% parenchyma diseased (< -950 HU)

14. Any cardiac comorbidity which the PI believes would compromise the safety of the patient after an IAB implant

15. Total Lung Capacity (TLC) < 100% predicted at screening

16. Diffusing Capacity of Carbon Monoxide (DLCO) < 15% or > 50% of predicted value at screening

17. Partial pressure of carbon dioxide (PaCO2) > 50 mm Hg or Denver scale greater than 55 mm Hg on room air at screening

18. Partial pressure of oxygen (PaO2) < 45 mm Hg or Denver scale less than 30 mm Hg on room air at screening

19. Plasma cotinine level > 13.7 ng/ml or carboxyhemoglobin (arterial or ear lobe capillary) > 2.5% at screening

20. Any other conditions, which, in the opinion of the Investigator, would make the patient unsuitable for inclusion, or could interfere with the patient participating in or completing the study
