Chronic lung disease
Idiopathic pulmonary fibrosis (IPF) is a serious chronic disease that affects the tissue surrounding the air sacs in the lung. Over time these changes can cause permanent scarring in the lungs, called fibrosis, that makes it more difficult to breathe. Common symptoms are shortness of breath and coughing.
A new drug called BI1015550 has been developed to help reduce the decline in lung function and improve quality of life in people with IPF. This clinical trial evaluates whether it is safe and well tolerated by people with IPF, and tests whether it helps to reduce the impact of IPF on lung function.
