Chronic obstructive pulmonary disease (COPD) is a progressive lung condition without a cure. It damages the airways and lungs, leading to debilitating breathlessness.
COPD covers a group of lung conditions, including chronic bronchitis and emphysema, that are characterized by chronic inflammation of the airways.
COPD has a devastating impact. Symptoms include shortness of breath, chronic cough, wheezing, tightness in the chest and unusual tiredness. Patients struggle with basic daily activities such as getting out of bed, showering and walking. It is the fourth leading cause of death globally, according to the World Health Organization. In 2019, it was estimated more than 390 million people worldwide were living with COPD.
Total annual direct medical costs related to COPD in the United States are projected to be approximately $60 billion by 2029.
Symptoms patients with COPD experience are commonly treated with bronchodilators, to relieve airway constriction and make it easier to breathe, and corticosteroids, to reduce lung inflammation. However, despite the wide availability of therapies, a 2025 survey of 1,615 patients with COPD showed that 43% of patients reported experiencing symptoms almost daily. These patients require additional treatment options.
Non-Cystic Fibrosis Bronchiectasis (bronchiectasis) is a chronic lung disease. Patients suffer from persistent cough, excess sputum production and frequent respiratory infections.
Cystic fibrosis (CF) is a potentially fatal genetic disease characterized by the build-up of thick, sticky mucus and infection that can damage many of the body’s organs.
Asthma is a common chronic inflammatory disease that makes it harder to move air in and out of the lungs.
