REDWOOD CITY, Calif., May 17, 2021 (GLOBE NEWSWIRE) -- Pulmonx Corporation (Nasdaq: LUNG) (“Pulmonx”), a global leader in minimally invasive treatments for severe lung disease, announced that key long-term follow-up data from the TRANSFORM® study was presented at the American Thoracic Society (ATS) virtual 2021 International Conference. The new data confirm the long-term benefits of the Zephyr® Endobronchial Valve (Zephyr Valve), the first minimally invasive procedure to treat patients with severe COPD/emphysema. The study shows that the Zephyr Valves provide significant benefits to patients including improvements over baseline in lung function and quality of life out to at least 24 months, and improvements in exercise capacity out to at least 18 months.i The Zephyr Valves are placed during a bronchoscopy procedure, so these benefits are achieved without the need for major surgery.
Patients treated with the Zephyr Valve in the TRANSFORM® study showed the following clinically and statistically significant improvements over baseline:
- Sustained Quality of Life improvements out to at least 24 months after treatment.
- Lasting lung function improvement out to at least 24 months post-treatment.
- Increased exercise capacity out to at least 18 months post-treatment.
- Long-term reduction in hyperinflation resulting in better breathing.
“Historically we have not had good treatment options for patients with severe disease who struggle to breathe even with medication adherence. This new data on the lasting benefits of endobronchial valves is significant because it means we now have a viable option to give patients sustained improvements, despite the progressive nature of this disease,” states Dirk-Jan Slebos, MD, Professor of Interventional Pulmonology, University of Groningen, The Netherlands. “There is no cure for COPD/emphysema, but to have a bronchoscopic treatment that can increase patients’ quality of life for years is a great advancement.”
“Our mission as a company is to improve the lives of patients with severe lung disease through minimally invasive technologies,” said Glen French, President and Chief Executive Officer of Pulmonx. “Thus, these long-term data further demonstrate that our Zephyr Valve is a safe, effective, and lasting treatment option for patients with severe COPD/emphysema.”

About the Study
TRANSFORM was the first multicenter RCT (17 centers) to evaluate effectiveness and safety of Zephyr Valves in patients with heterogeneous emphysema prospectively identified for absence of collateral ventilation in target lobe. The study was also intended to assess the long-term clinical outcomes and safety profile of Zephyr Valve treated patients out to 24-months and long-term results have not been previously reported. TRANSFORM enrolled 97 patients with heterogeneous emphysema who were CV-negative by Pulmonx’ proprietary Chartis® assessment technology. Patients were randomized to treatment with 65 receiving the Zephyr Endobronchial Valves and 32 patients randomized to standard of care (optimal medical management). Study patients in both groups were evaluated at 3- and 6-months at which time the standard of care patients could exit the study. Zephyr valve treated patients were followed out to 24-months with evaluations at 12-, 18-, and 24-months. The results for the primary endpoint were previously reported.ii The long-term data show that in patients with severe heterogeneous emphysema, Zephyr Valve treatment provided a durable reduction in hyperinflation out to at least 24-months, resulting in clinically significant improvements in lung function, quality of life and exercise capacity out to at least 18-months, clinically significant improvements in lung function and quality of life out to at least 24-months, and acceptable long-term safety profile.
About the Zephyr Valve Treatment
The Zephyr Valve is a minimally invasive treatment option for severe COPD/emphysema, a chronic, progressive, and irreversible lung disease characterized by the destruction of lung tissue. The loss of the lung’s natural elasticity and the collapse of airways cause air to become trapped in the lung. This makes breathing inefficient and patients are always short of breath, making the most nominal physical activities difficult. Placed via bronchoscopy, the valves block off a diseased portion of the lung to prevent air from getting trapped and reduce hyperinflation which allows the healthier lung tissue to expand and take in more air. This results in patients being able to breathe easier, be less short of breath, and have an improvement in quality of life.iii More than 20,000 patients have been treated with the Zephyr Valve worldwide and the treatment is included in national and global treatment guidelines for COPD including an ‘Evidence A' rating from The Global Initiative for Chronic Obstructive Lung Disease (GOLD).
