This is an interventional treatment trial for Cirrhosis

Arms of the Study

Experimental

Arm Label

Placebo

VE303

Arm Description

VE303 is a live biotherapeutic product comprising 8 nonpathogenic commensal strains of Clostridia.

Outcomes

Primary Outcome Measures

Number of serious adverse events up to week 6
Change in Psychometric Hepatic Encephalopathy Score (PHES) as a measure of cognitive function from pre-vancomycin to week 6
This score is a battery of 5 paper-pencil tests that evaluate cognitive and psychomotor processing speed and visuomotor coordination. Scores on each subtest are assigned values based on age-related norms (1+ for scores better than 1 standard deviation (SD) above the normal mean to -3 for scores more than 3 SDs below the normal mean). Combined scores vary from +6 to -18.

Secondary Outcome Measures

Number of hospitalizations for overt hepatic encephalopathy (OHE) up to week 26
Adverse events up to week 26
Change in Patient Reported Outcome Measurement Information System (PROMIS) Global Health reported from pre-vancomycin to week 26
The PROMIS v 1.1 is a 10 question scale where participants select answers from (0) up to (10). Higher scores indicate better quality of life.
Time to overt HE
Change in microbiome composition from pre-vancomycin to week 26
This will be calculated by beta diversity between stool collection timepoints and will have metagenomic sequencing on stool to assess this.
Change in serum and stool biomarkers from pre-vancomycin to week 26
PHES from pre-vancomycin to week 26
This score is a battery of 5 paper-pencil tests that evaluate cognitive and psychomotor processing speed and visuomotor coordination. Scores on each subtest are assigned values based on age-related norms (1+ for scores better than 1 standard deviation (SD) above the normal mean to -3 for scores more than 3 SDs below the normal mean). Combined scores vary from +6 to -18.

5. Study Description

Brief Summary
This research is studying the use of a new drug to learn about its safety and efficacy as a treatment for hepatic encephalopathy. Eligible participants will be enrolled and given oral antibiotics followed by 14 days of the study drug (placebo vs.VE303). There will be visits as well as other procedures to collect blood and stool samples, and have tests of your cognition (thinking) for this research study. The hypothesis is that VE303 will safely and effectively improve cognitive function in patients with a history of overt hepatic encephalopathy.

Phase 2
Interventional Study Model
Parallel Assignment
Model Description
Subjects will be randomized 2:1 to VE303 vs placebo. There will be no stratification. After the trial enrolls the first 9 patients, an interim analysis to evaluate safety of VE303 in this population will take place. If there is no concern for a higher rate of Serious adverse events (SAEs) in the VE303 group, enrollment will continue to reach a total of 18 patients.
