A Study to Test Whether BI 685509 Alone or in Combination With Empagliflozin Helps People With Liver Cirrhosis Caused by Viral Hepatitis or Non-alcoholic Steatohepatitis (NASH) Who Have High Blood Pressure in the Portal Vein (Main Vessel Going to the Liver)

This study is open to adults with liver cirrhosis caused by hepatitis B, hepatitis C or nonalcoholic steatohepatitis (NASH). People can join this study if they have high blood pressure in the portal vein (main vessel going to the liver). The purpose of this study is to find out whether a medicine called Avenciguat (BI 685509) taken alone or in combination with a medicine called empagliflozin helps people with this condition. Participants take Avenciguat (BI 685509) as tablets twice a day for 8 weeks. Half of the participants with NASH who also have type 2 diabetes take empagliflozin as tablets once a day in addition to Avenciguat (BI 685509). Participants are in the study for about 3 months. During this time, they visit the study site about 10 times. At 2 of the visits, the doctors check the pressure in a liver vein to see whether the treatment works. This is done with a catheter (a long thin tube) and gives information about the pressure in the portal vein. The doctors also regularly check participants' health and take note of any unwanted effects.
