New lung implant could help severe emphysema patients breathe easier
NCT ID NCT07086339
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new device called the IAB 50 Flex, an implantable artificial bronchus for adults with severe COPD or emphysema. The trial will enroll 20 participants across two hospitals to check if the implant is safe and if it helps improve breathing and daily activity. The main goal is to see if there are any serious side effects related to the device or procedure within 90 days.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- implantable pulmonary stent (IAB 50 Flex)
- What this could lead to
- If successful, this implant could offer a new way to help people with severe emphysema breathe easier and improve daily function.
- What could go wrong
- This is a very early, small trial (20 people) focused on safety, not yet proven to work. The implant may cause serious side effects or not help breathing.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Signed Informed Consent 2. Diagnosis of COPD/emphysema 3. At least 22-years of age 4. 18 ≤ BMI ≤ 32 5. 6-minute walk Distance of between 100 - and 400 meters 6. Stable disease with less than 10-mg prednisone (or equivalent) daily 7. Non-smoking for 4-months prior to screening interview (this includes tobacco, vaping, marijuana, etc.). 8. FEV1 between 15% and 45% of predicted value at baseline exam 9. FEV1/FVC \<70% 10. Subject has ≥25% emphysema destruction score in each lung defined by areas of low attenuation less than -950 HU, as determined by CT core lab. 11. Subject has homogeneous or heterogeneous emphysema, and at least one lung has a 15% difference between upper and lower lobes in emphysema destruction score less than -950 HU, as determined by CT core lab. 12. RV \> 175% of predicted value. 13. mMRC score ≥ 2 Exclusion Criteria: 1. Currently participating in another clinical study that involves surgery, interventional or pharmaceutical treatment 2. α-1 Antitrypsin deficiency 3. Women of child-bearing potential 4. More than 2 COPD exacerbation episodes requiring hospitalization in the last year prior to screening 5. Any COPD exacerbations requiring hospitalization within 6-weeks of planned intervention 6. Two or more instances of pneumonia episodes requiring hospitalization in the last year prior to screening 7. Clinically significant mucus production or chronic bronchitis 8. Myocardial Infarction or unstable / uncontrolled congestive heart failure within 6-months of screening 9. Prior lung transplant, LVRS, bullectomy, lobectomy or endoscopic lung volume reduction (ELVR) 10. Clinically significant bronchiectasis 11. Unable to safely discontinue anti-coagulants or platelet activity inhibitors for 7-days 12. Uncontrolled pulmonary hypertension (systolic pulmonary arterial pressure \>45 mm Hg) or evidence or history of cor pulmonale as determined by recent echocardiogram 13. Suspected malignant pulmonary nodule or other lung cancer 14. 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: * Large bullae encompassing greater than 30% of either lung * Insufficient landmarks to evaluate the CT study using the software as it is intended * All lobes are less than 25% parenchyma diseased (\< -950 HU). 15. Any cardiac comorbidity which the PI believes would compromise the safety of the patient after an IAB implant 16. TLC \< 100% predicted at screening 17. DLCO \< 15% or \> 50% of predicted value at screening 18. PaCO2 \> 50 mm Hg at screening 19. PaO2 \< 45 mm Hg in room air at screening 20. Plasma cotinine level \> 13.7 ng/ml or carboxyhemoglobin (arterial or ear lobe capillary) \>2.5% at screening. 21. Current diagnosis of substance abuse disorder. 22. Current diagnosis of any of the following: Major Depressive Disorder (MDD), Schizoaffective Disorder, Schizophrenia, Borderline Personality Disorder, Bipolar Disorder 23. 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.
