Conditions

Patients with overt hepatic encephalopathy (OHE) and acute decompensation (AD) of liver cirrhosis or acute-on chronic liver failure (ACLF) grade 1

Brief summary

Time to improvement of OHE as assessed by HEGI. Improvement is defined as: a) A reduction of HE grades 4 or 3 to grade ≤2, or b) A reduction of HE grade 2 to grade <2.

Detailed description

Safety and tolerability defined as: a) The incidence and severity (National Cancer Institute Common Terminology Criteria for Adverse Events [NCI CTCAE] v5.0 grade) of treatment-emergent adverse events (TEAEs) including serious adverse events (SAEs), comprising the evaluation of vital signs, ECG parameters, and laboratory parameters., PK/PD: a) PK (for active treatment arms): blood and peritoneal fluid concentration-time profile of BL-corrected citric acid and lipids in patients treated with VS-01. b) PD (for all arms): change from BL in fasting blood and peritoneal fluid ammonia levels.
