Idiopathic pulmonary fibrosis (IPF) and related progressive pulmonary fibrosis diseases are rare diseases that cause scarring of the lungs. This results in people having difficulty breathing and performing daily activities as oxygen is not properly being taken up by the lungs. The disease continues to get worse and cannot be cured yet. Major progresses have already been made to diagnose the disease and to treat patients with disease-delaying medication. However, patients still have several unmet needs which require urgent action as emphasized internationally by patient advocacy groups and healthcare professionals.
