• Registration Number: NCT07051707
• Lead Sponsor: Nuvaira, Inc.

Brief Summary

The dNerva Lung Denervation System is one-time treatment intended to improve breathing in Chronic Obstructive Pulmonary Disease (COPD) patients on standard medical care. The purpose of this study is to confirm the safety and efficacy of the Nuvaira Lung Denervation System in the treatment of COPD.

Detailed Description

The primary objective of this study is to demonstrate the superiority of treatment with the dNerva Lung Denervation System on top of standard medical care (Treatment arm) compared to standard medical care alone (Control arm) to improve lung function in COPD participants with high RV and low emphysema.

The secondary objective is to compare other efficacy assessments between the Treatment arm and the Control arm, and to confirm the safety profile of lung denervation.

Primary Outcome Measures

Name	Time	Method
The primary endpoint is improvement in FEV1 at 6 months.	6 months	FEV1 will be measured through post bronchodilator (Post-BD) force expiratory volume in 1 second (FEV1) test. Change in FEV1 is defined by a comparison between study arms of the mean change in Post-BD FEV1 based on a linear model for change in Post-BD FEV1 from baseline to 6 months follow-up.
