Clinical Development Program AIRFLOW-2

Study Overview

AIRFLOW-2 was a double-blinded, sham controlled, multicenter randomized clinical trial to assess respiratory adverse events in 82 moderate-to-severe COPD patients with high symptom burden despite optimal drug therapy. Results from our AIRFLOW-2 Clinical Trial confirm the safety of the procedure and provides a solid clinical and economic basis for a pivotal trial, AIRFLOW-3.

Results: Impact on Two-Year Outcomes2
62% Lower Risk of Severe Exacerbations
in COPD Patients with TLD

Published in the International Journal of Chronic Obstructive Pulmonary Disease, November 20202

The clinical impact of TLD is durable, as it is found to reduce the risk of serious COPD adverse events over 2 years with stabilized lung function. The reduction of severe COPD exacerbations has the potential to improve long-term clinical outcomes and reduce healthcare costs.

Nuvaira Clinical Development Program AIRFLOW-1

Study Overview

AIRFLOW-1 was a multicenter safety and dose ranging study of TLD in moderate-to-severe COPD patients. Results from our AIRFLOW-1 Clinical Trial show that patient lung function remained stable up to 3 years after treatment and that the annual rate of decline in FEV1 decreased after treatment.21,22

Published in Respiratory Research, February 202121

TLD in COPD patients demonstrated a positive safety profile out to 3 years, with no late-onset serious adverse events related to denervation therapy. Clinical stability in lung function, quality of life, and exacerbations were observed in TLD treated patients over 3 years of follow up.
