Design outcomes

Primary

MeasureTime frame
The primary efficacy endpoint is improvement from Baseline (liver biopsy at the Baseline Biopsy Visit, or a historical liver biopsy obtained within 24 weeks of randomization) in disease activity and no worsening of liver fibrosis on the NASH Clinical Research Network (CRN) fibrosis score at Week 48. The improvement in disease activity is defined as improvement in NAFLD Activity Score (NAS) >=2 points. The worsening of fibrosis is defined as any numerical increase in the stage.
