Обзор

This is a multicenter, prospective, observational surveillance enrolling 140 consecutive patients with severe emphysema who are candidates for bronchoscopic lung volume reduction using Zephyr Endobronchial Valve at up to 20 centers across Japan and followed for 12 months.

Подробное описание

This is a multicenter, prospective, observational surveillance across 20 centers in Japan enrolling 140 consecutive adult patients with hyperinflation of the lungs due to severe emphysema who are considered to be appropriate candidates for BLVR using Zephyr Endobronchial Valve (EBV, Pulmonx Corporation) and confirmed to have little to no collateral ventilation in the target lobe.

Enrolled (consented) subjects will undergo a bronchoscopy procedure with the Chartis assessment to confirm that little to no collateral ventilation is present (CV- status) followed by EBV placement in the most diseased lobe. Subject will be hospitalized for a minimum of 3 nights for observation and followed up for 12 months.

Subjects with collateral ventilation will be exited from the surveillance without treatment.

The primary endpoint is incidence rate of pneumothorax at Day 45 post-index procedure.

The effectiveness will be evaluated from Baseline to specified timepoint based on changes in lung function, exercise capacity, dyspnea and quality of life. A high-resolution computed tomography (HRCT) will be performed at Day 45 and Month 12 to determine Treated Lobe Volume Reduction (TLVR). Lung function will be assessed at Month 3, 6 and 12 by measuring post-bronchodilator forced expiratory volume in 1 second (FEV1), residual volume (RV) and 6 Minutes Walking Distance. The safety will be evaluated based on incident rate of treatment emergent adverse events through Month 12.

Subjects will be required to complete a pulmonary rehabilitation program between Day 45 and Month 3 per local/national guidelines.

Вмешательства

  • Устройство Zephyr Endobronchial Valve
    Zephyr Valve provides an alternative technique to achieve bronchoscopic lung volume reduction (BLVR) using a minimally invasive approach. Zephyr Valve is a tiny unidirectional valve. During BLVR, multiple valves are placed to occlude a hyperinflated lobe of the lungs, allowing air to escape while blocking airflow into the treated lobe. This is intended to result in a reduction in lung volume and hyperinflation in the targeted area. Consequently, the remaining lobes can expand more fully, the ove
