This study is open to adults with liver cirrhosis and 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 helps people with this condition.

Participants are put into 3 groups randomly, which means by chance. Participants in 2 groups take different doses of Avenciguat as tablets twice a day. Participants in the placebo group take placebo as tablets twice a day. Placebo tablets look like Avenciguat tablets but do not contain any medicine.

Participants are in the study for about 8 months. During this time, they visit the study site about 14 times. At 3 of the visits, the doctors check the pressure in a liver vein. This is done with a catheter (a long thin tube) and gives information about the pressure in the portal vein. The change in blood pressure is then compared between the groups to see whether the treatment works.

The doctors also regularly check participants' health and take note of any unwanted effects.

INTERVENTIONAL

Intervention Type : DRUG
Intervention Description : Participants received Avenciguat twice daily (BID) throughout the study. Up-titration depended on the assigned dose group. At Visit 2 (Week 1), each dose included one 1 mg Avenciguat tablet. At Visit 3 (Week 2), the dose was increased to one 2 mg Avenciguat tablet per dose. From Visit 4 onward (Week 3+), participants received one 3 mg Avenciguat tablet per dose. This regimen continued for 24 weeks, with all doses taken with water, with or without food.

Intervention Arm Group : Avenciguat 2 mg BID;Avenciguat 3 mg BID;

Intervention Type : DRUG
Intervention Description : Participants received matching placebo twice daily (BID) throughout the study. At Visit 2 (Week 1), each dose included one 1 mg and one 2 mg placebo tablet (four tablets daily). A pseudo up-titration was applied at Visit 3 (Week 2), maintaining the same tablet composition to preserve blinding. From Visit 4 (Week 3) onward, a second pseudo up-titration adjusted each dose to one 2 mg and one 3 mg placebo tablet (four tablets daily). All doses were taken with water, with or without food.

Intervention Arm Group : Placebo;
