Company Receives Approval to Revise CE Labeling

August 29, 2012, Peseux, Switzerland – Pulmonx, an emerging leader in interventional pulmonology, announced today that its European notified body has granted CE approval for revised labeling of its Zephyr® Endobronchial Valve (EBV). The approval was based upon an independent review of two separate clinical data sets in which patients with hyperinflation associated with a genetic form of emphysema, Alpha-1 antitrypsin deficiency (AATD), were treated using the Pulmonx Zephyr EBV.

These new data sets reported improvements for FEV1 (forced expiratory volume in one second) and Residual Volume in AATD patients treated with Zephyr endobronchial valves, showing that patients with hyperinflation associated with emphysema can benefit from EBV treatment, independent of the underlying cause of the disease. No new procedural or device risks that may be associated with the treatment of AATD patients with the Pulmonx EBV were observed. The newly approved labeling provides a therapeutic option for physicians to use the Zephyr EBV to treat patients afflicted with hyperinflation associated with Alpha-1 Antitrypsin Deficiency.

“We have seen great success in the use of endobronchial valve therapy in selected patients suffering from Alpha-1 Antitrypsin Deficiency.” said Gunnar Hillerdal, Associate Professor of Lung Medicine, Karolinska University Hospital, Stockholm, Sweden. “The treatment options for these patients were previously very limited but their anatomy and the typical distribution of their disease can make them excellent candidates for EBV treatment. The recent label change should encourage pulmonologists to evaluate these patientsfor such treatmentwith confidence,” he continued.

About Alpha-1

Alpha-1 antitrypsin deficiency (AATD) is an inherited condition in which the body does not make enough of a protein that protects the lungs and liver from damage. Severe AATD can lead to emphysema or chronic obstructive pulmonary disease (COPD) in adult life. Page 2
