Study Endpoints

Primary Endpoints

Number of participants with adverse events (AEs) and serious adverse events (SAEs)
Up to 8 weeks
Number of participants with potentially clinically relevant changes in electrocardiogram (ECG), vital signs, and clinical laboratory tests
Up to 8 weeks
Change from baseline in Liver Stiffness measurement (LSM) reduction using FibroScan® at Week 52 (kiloPascal)
Baseline (Day 1) and up to Week 52

Liver stiffness will be measured by vibration-controlled transient elastography (VCTE) using the FibroScan® device.

Change from baseline in model for end-stage liver disease (MELD) score reduction at Week 52
Baseline (Day 1) and up to Week 52

MELD is a scoring system for assessing the severity of chronic liver disease. MELD scores range between 6 and 40, with 40 being the most severe.

Predicted percent change from baseline in liver biopsy-derived HSD17B13 protein expression levels
Baseline (Day 1) and up to Week 28
Predicted percent change from baseline in liver biopsy-derived HSD17B13 mRNA expression levels
Baseline (Day 1) and up to Week 28
Percentage of Participants Achieving ≥ 1 Stage Improvement in Histological Fibrosis with no Worsening of NASH - F3 Cohort
At Week 52

Improvement in histological fibrosis is assessed with Clinical research network (CRN) Scoring. No worsening of NASH is defined as no increase in the NAFLD Activity Score (NAS) for steatosis, ballooning, or inflammation.

Percentage of Participants Achieving NASH Resolution with no Worsening of Fibrosis - F3 Cohort
At Week 52

NASH resolution is defined as a ballooning score of 0 and an inflammation score of 0-1. No worsening of fibrosis is defined as no increase in CRN fibrosis score.
