Overview

This study is open to people with cirrhosis caused by a liver disease called MASH (metabolic dysfunction-associated steatohepatitis). The purpose of this study is to find out how well a medicine called BI 770371 is tolerated.

Participants are put into 2 groups by chance. One group gets BI 770371 as an infusion into a vein and the other group gets placebo as an infusion into a vein. Placebo infusions look like BI 770371 infusions but do not contain any medicine. Participants get an infusion every 3 weeks for 12 weeks.

Participants are in the study for about 5 months. During this time, they visit the study site 16 times. This also includes 1 overnight stay at the study site. The doctors regularly check participants' health and collect information on any health problems of the participants. The results are compared between the 2 groups.
