This is a two part Phase IIa/b multicentre, randomised, double-blind, placebo-controlled, parallel group dose-ranging study to assess the efficacy, safety, and tolerability of the combination of zibotentan and dapagliflozin, and dapagliflozin monotherapy versus placebo in participants with cirrhosis with features of portal hypertension.
Part A will assess the efficacy, safety, and tolerability of the combination of B mg zibotentan and 10 mg dapagliflozin versus placebo in participants with Child-Pugh A cirrhosis with features of portal hypertension and with no history of decompensation events. If the safety profile is determined to be acceptable at the conclusion of Part A, Part B will investigate efficacy, safety, and tolerability of A mg, B mg, or C mg zibotentan combined with 10 mg dapagliflozin and of 10 mg dapagliflozin monotherapy versus placebo in participants with cirrhosis with features of portal hypertension. Part B will include a broader range of Child- Pugh A and Child-Pugh B cirrhosis participants, including those with more severe disease, a history of decompensation events, or current ascites. The study will be conducted in approximately 30 to 45 study centres in North America, Asia, and Europe.
