A Study to Test Whether Avenciguat Helps People With Liver Cirrhosis and High Blood Pressure in the Portal Vein (Main Vessel Going to the Liver) Who Had Bleeding in the Esophagus or Fluid Accumulation in the Belly

• Status: Active, not recruiting
• Trial end date: 2024-05-31
• Target enrollment: 0
• Participant gender: All

Summary

This study is open to adults with advanced liver cirrhosis caused by hepatitis B, hepatitis C, alcohol-related liver disease, non-alcoholic steatohepatitis or other causes. People can join the study if they have high blood pressure in the portal vein (main vessel going to the liver) and bleeding in the esophagus or fluid accumulation in the belly. The purpose of this study is to find out whether a medicine called avenciguat helps people with this condition.

Participants are put into 2 groups by chance. One group takes avenciguat tablets and the other group takes placebo tablets. Placebo tablets look like avenciguat tablets but do not contain any medicine. Participants take a tablet twice a day for 8 weeks.

Participants are in the study for 2 to 3 months. During this time, they visit the study site regularly. At 2 of the visits, the doctors check the pressure in the liver vein by inserting a catheter (a long thin tube) that gives information about pressure in the portal vein. The change in blood pressure is then compared between the 2 groups to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.

Further inclusion criteria apply

Exclusion Criteria:
