BI 1015550

for Pulmonary Fibrosis

This study is open to people with idiopathic pulmonary fibrosis (IPF) or progressive pulmonary fibrosis (PPF). They can only take part if they have completed treatment in a previous study with a medicine called BI 1015550 (study 1305-0014 or 1305-0023). The goal of this study is to find out how well people with pulmonary fibrosis tolerate longterm treatment with BI 1015550. The study also tests whether BI 1015550 improves lung function and prolongs the time until symptoms get worse, participants need to go to the hospital, or die. Every participant takes BI 1015550 as tablets for up to 1 year and 10 months. The participants may also continue their regular treatment for pulmonary fibrosis during the study. Participants visit their doctors regularly. During these visits, the doctors collect information on any health problems of the participants. Participants also regularly do lung function tests.
