Original description

A Phase 2, multi-center, randomized, controlled, open-label study to evaluate the effects of the intraperitoneal, liposomal formulation VS-01 in patients with an acute episode of hepatic and/or extrahepatic organ dysfunctions and failures in the presence of liver cirrhosis (Acute-on-Chronic Liver Failure, ACLF) and accumulation of fluid in the abdominal cavity (ascites)Read full original descriptionShow less

A Phase 2a, Open-label, Randomized, Controlled, Multi-center Proof of Concept Study to Assess the Efficacy, Safety, and Tolerability of VS-01 on Top of Standard of Care, Compared to Standard of Care Alone, in Adult Patients With Acute-on-chronic Liver Failure (ACLF)

A Phase 2, multi-center, randomized, controlled, open-label study to evaluate the effects of the intraperitoneal, liposomal formulation VS-01 in patients with an acute episode of hepatic and/or extrahepatic organ dysfunctions and failures in the presence of liver cirrhosis (Acute-on-Chronic Liver Failure, ACLF) and accumulation of fluid in the abdominal cavity (ascites)
