First in Human Study to Assess an Implant to Treat Severe Emphysema (BREATHE-1)

Inclusion Criteria: Age ≥ 35 and ≤ 80 years old Computed tomography (CT) scan evidence of homogeneous or heterogeneous emphysema At least one target lobe with > 35% destruction (percent of voxels with < -950 Hounsfield units on CT) Post-bronchodilator ratio of FEV1/FVC < 0.7 at screening Post-bronchodilator FEV1 percent predicted ≥20% and ≤50% of predicted at screening Post-bronchodilator RV > 180% predicted Post-bronchodilator RV/TLC ≥ 0.55 at screening Marked dyspnea, scoring ≥ 2 on the modified Medical Research Council scale of 0-4 Cotinine testing at screening indicates nonsmoker and stopped smoking at least 8 weeks before entering the trial and agrees to refrain from smoking for duration of study participation Participation in a pulmonary rehabilitation program and/or confirmed to have been engaged or attempted regular physical activity in the 12 months prior to the first Apreo Procedure and agrees to continue or restart regular physical activity for the duration of the study Fully vaccinated for Covid-19 (up to date per Australian Government Guidelines) and has current pneumococcus and influenza vaccination (or documented clinical intolerance) Cognitively and physically able to provide written informed consent and complete participant questionnaires Exclusion Criteria: Arterial blood PaCO2 > 60 mmHg (8 kPa) or PaO2 ≤ 45 mmHg (6 kPa) DLCO <20% at screening Steroid therapy of 10 mg prednisolone (prednisone) or more per day Three or more acute exacerbations of COPD in the past year before enrollment Two or more hospitalizations for acute exacerbations of COPD or respiratory infections in the past year before enrollment Any acute exacerbation of COPD or respiratory infection less than 4 weeks before the first Apreo Procedure Previous lung volume reduction surgery or lobectomy, segmentectomy or bullectomy, vapor, glue, or other pulmonary device implant Known history of pulmonary arterial hypertension Presence of a giant bulla (≥ 30% of hemithorax) History of excessive dynamic airway collapse of the trachea or main bronchi History of adult asthma or chronic bronchitis Presence of suspicious pulmonary nodule/infiltrate that requires additional follow-up, diagnostics or treatment Unequivocal and symptomatic bronchiectasis Unequivocal lung cancer or other current cancer diagnosis except non-metastasized basal cell skin cancer Uncontrolled hypertension (blood pressure that is inadequately treated or resistant to treatment) with a systolic > 200 mmHg or diastolic > 110 mmHg at screening or prior to first Apreo Procedure Uncorrectable coagulopathy or other condition likely to increase risk of peri- or post- Apreo Procedure bleeding On anticoagulant or antiplatelet therapy and unable or unwilling to hold for Apreo Procedure Coronary artery disease with angina History of myocardial infarction within 6 months History of a stroke less than 1 year before the first Apreo Procedure Clinical history of heart failure with documented LVEF ≤ 40% Clinical history of diabetes with a HbA1c > 9.0% Estimated glomerular filtration rate (eGFR) <30 mL/min/1.73m2 (CKD-EPI) OR participant with kidney failure (Stage 5 kidney disease) Mechanical ventilator dependence except participants using nocturnal bi-level positive airway pressure (biPAP) or continuous positive airway pressure (CPAP) are allowed if it would not preclude safe implantation of the study device Pregnant, lactating, or women of childbearing potential who plan to become pregnant within the study duration Known hypersensitivity to nitinol Significantly immunocompromised, such as organ transplant recipients, those with congenital immune deficiencies, AIDS, or severe rheumatoid arthritis Any disease or condition likely to limit survival to less than one year Concomitant illnesses or medications that may pose a significant increased risk for complications following an Apreo Procedure Currently enrolled in another trial and actively receiving experimental treatment Any condition in the opinion of the investigator that would interfere with safe and complete collection of study data including the safe conduction of bronchoscopy procedures
