The study is designed to evaluate the effects of the combination of zibotentan and
dapagliflozin and dapagliflozin monotherapy versus placebo on the hepatic venous pressure gradient (HVPG) response in participants with cirrhosis with features of portal hypertension at 6 weeks of treatment.

Part A is to evaluate the absolute
change in HVPG at 6 weeks from baseline in participants treated with 2.5 mg zibotentan combined with 10 mg dapagliflozin versus placebo. The primary efficacy objective for Part B is to evaluate the proportion of participants treated with 1, 2.5, or 5 mg zibotentan combined with 10 mg dapagliflozin and 10 mg dapagliflozin monotherapy versus placebo achieving a ≥ 20% decrease in HVPG or a reduction to or below 12 mmHg in HVPG
