Interstitial lung disease
Interstitial lung disease (ILD) is a group of diseases which that cause scarring of the lungs. The scarring causes lung stiffness which can make it difficult to breathe. Common symptoms include shortness of breath, dry cough, chest discomfort, fatigue and occasionally weight loss. Lung damage from ILDs is usually permanent, so available treatments aim to relieve symptoms, improve quality of life and slow disease progression.
BI 1015550 is a new anti-inflammatory drug which was developed to improve outcomes in diseases associated with tissue scarring, including ILDs. This clinical trial tests whether the addition of BI 1015550 to standard care helps to reduce the decline in lung function in people with ILD. Participants in the study will be randomly assigned to receive the study drug plus standard care or placebo plus standard care.
