This study is open to adults with idiopathic pulmonary fibrosis (IPF) who are 40 years and older. The purpose of this study is to find out whether a medicine called pirfenidone changes the amount of a medicine called BI 1015550 in the blood. Some people may take more than one medicine at a time. Therefore, it is important to understand how different medicines influence one another.
Participants take one dose of BI 1015550 as a tablet. Participants then take one tablet of pirfenidone 3 times a day for one week. The dose is then increased to 2 tablets 3 times a day for the second week. In the third week the dose is increased further to 3 tablets 3 times a day. Participants then take another dose of BI 1015550 as a tablet.
Participants are in the study for a little over 1 month. During this time, they visit the study site 15 times. Two of the visits include overnight stays at the study site. The study staff also contacts the participants by phone. During the visits, the doctors collect information about participants' health and take blood samples from the participants. They compare the amount of pirfenidone and BI 1015550 in the blood. Doctors also regularly check participants' health and take note of any unwanted effects.
