BREATHING INNOVATION INTO LIFE
About Emphysema A Clinical Research Study for people with severe emphysema. Find out if this study may be Emphysema is a form of chronic obstructive pulmonary disease (COPD) that affects five million people in the US. The primary symptom of emphysema is shortness of breath. For some people, breathing becomes difficult even during routine activities, such as walking or eating. right for you. In emphysema, tiny air sacs in the lungs (called alveoli) break down and lose elasticity. Air gets trapped in the alveoli and the diseased region of the lung expands. As it expands, the diseased region compresses healthier regions of the lung making it difficult to breathe.

Current Treatment Options Emphysema patients often use medication, supplementary oxygen and/or inhalers to improve their symptoms. However, many still have difficulty breathing. Today, severe emphysema patients have no alternatives except more invasive The Zephyr Endobronchial Valve is an investigational device that is intended to reduce the volume of the diseased region of the lung to allow healthier areas to In this minimally invasive procedure, Zephyr valves are placed in the diseased region of the lung. BEFORE TREATMENT The one-way valves block airflow into the diseased region (green arrows) and allow trapped air and fluids to escape (orange arrows). AFTER TREATMENT surgical procedures. function more efficiently, helping patients breathe better. ACTUAL SIZE With emphysema, air becomes trapped in the alveoli, causing hyperinflation, which compresses the healthier regions of the lung. As the diseased region of the lung shrinks in size, healthier regions may expand and function more efficiently.
Study Overview The LIBERATE Study is evaluating the Zephyr Endobronchial Valve in patients with severe emphysema. The Zephyr valve is an investigational device in the United States, which means that it has not been cleared by the Food and Drug Administration (FDA) for sale in the US. The LIBERATE Study is a clinical trial with two groups. Participants are assigned at random to the Treatment group or to the Control group. The Treatment group will receive the Zephyr valve in combination with optimal medical therapy. The Control group will receive optimal medical therapy alone. For every three participants in the study, two will go into the Treatment group and one will go into the Control group. FOR PATIENTS WITH SEVERE EMPHYSEMA
