Recruiting NA COPD

Compares treatment options for COPD

Official title Trial Evaluating the Rate of Pneumothorax in Severe Emphysema Secondary to Endoscopic Volume Reduction With Two-stage ZEPHYR® Valves Versus Endoscopic Volume Reduction With One-stage ZEPHYR® Valves

ClinicalTrials.gov ID: NCT06181357

What this study is testing

What it's testing
Chronic obstructive pulmonary disease (COPD) affects 3.5 million people and is the third leading cause of death worldwide. Emphysema involves air retention in the lungs and is ultimately responsible for a major deterioration in the quality of life.

Who can take part

Ages 35 to 80

You may be able to join if

  • Patient able to give informed consent and participate in the study
  • Age ≥ 35 years old and ≤ 80 years old at the time of signing the consent
  • Emphysema (homogeneous or heterogeneous) on a recent CT scan (\< 6 months). Heterogeneous emphysema defined by a difference of at least 15%...
  • Destruction ≥ 50% (threshold 910 HU) of the target lobe on the chest scanner

Who can join
  • Patient able to give informed consent and participate in the study
  • Age ≥ 35 years old and ≤ 80 years old at the time of signing the consent
  • Emphysema (homogeneous or heterogeneous) on a recent CT scan (\< 6 months). Heterogeneous emphysema defined by a difference of at least 15% destruction (threshold 910HU) between two adjacent lobes.
  • Destruction ≥ 50% (threshold 910 HU) of the target lobe on the chest scanner
  • Smoking quit for 3 months
  • Dyspnea ≥ 2 according to the modified Medical Research Council (mMRC) questionnaire)
  • Post-bronchodilator FEV between 15 and 50% theoretical
  • Post-bronchodilator total lung capacity ≥ 100% theoretical and post-bronchodilator residual volume ≥ 175% theoretical
  • Distance traveled during the TM6M ≥ 100m
  • Member of or beneficiary of a social security scheme
What rules you out
  • Asthma considered as main diagnosis
  • Recurrent exacerbations: (\>3 over the last year or 2 requiring hospitalization)
  • Myocardial infarction or stroke in the 6 months prior to inclusion
  • Symptoms of heart failure in the 6 months prior to inclusion
  • Chest CT abnormalities: giant bulla (occupying more than a third of the pulmonary field), paraseptal emphysema, pulmonary nodule greater than 0.8cm (not applicable pulmonary nodules known for more than a year and...
  • Pulmonary tomoscintigraphy:
  • Patients for whom the least perfused lobe is not the one with the highest emphysema destruction score
  • Patients with homogeneous emphysema for whom the perfusion delta (difference in perfusion between the ipsilateral lung and the treated lobe) is less than 10%
  • Arterial blood gas analysis in ambient air: Hypoxemia in ambient air (PaO2 \ 55 mmHg)
  • Echocardiography:
  • Left Ventricular Ejection Function \< 45%
  • Systolic pulmonary arterial pressure \> 45 mmHg
  • History of pneumonectomy, lung surgery homolateral to the lobe targeted for endoscopic lung volume reduction
  • History of pneumothorax homolateral to the lobe targeted for endoscopic lung volume reduction
  • History of endoscopic volume reduction
  • Oral corticosteroid therapy \> 20 mg/day within the 4 weeks preceding inclusion
  • Symptomatic bronchial dilatations, bronchial colonization with pseudomonas aeruginosa, multi-resistant bacteria or aspergillus origin
  • Metastatic cancer undergoing treatment or whose treatments ended less than 5 years ago
  • Pregnant or breastfeeding women
  • Nickel allergy
  • Patient under guardianship, curatorship or under judicial protection
  • Participation in another treatment clinical research
  • Any other condition which, in the opinion of the investigator, could interfere with the objective of the study or would cause the subject's participation in the study to be suboptimal, in particular (non-exhaustive...
