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 study centres in North America and Europe.
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.
