Brief summary

The primary objective of this study is to evaluate whether selonsertib (SEL; GS-4997) can cause fibrosis regression and reduce progression to cirrhosis and associated complications in adults with NASH and bridging (F3) fibrosis.

MeasureTime frameDescription
Percentage of Participants Who Achieved a ≥ 1-Stage Improvement in Fibrosis According to the Nonalcoholic Steatohepatitis (NASH) Clinical Research Network (CRN) Classification Without Worsening of NASH at Week 48Week 48Fibrosis improvement was defined as ≥ 1-stage decrease from baseline in fibrosis according to the NASH CRN classification. NASH CRN fibrosis stages range from 0 to 4, with higher scores indicating greater fibrosis (0=None, 4=Cirrhosis). Worsening of NASH was defined as ≥ 1 point increase from baseline in hepatocellular ballooning or lobular inflammation according to the Non-Alcoholic Fatty Liver Disease (NAFLD) Activity Score (NAS) criteria. As defined by NAS, hepatocellular ballooning ranges from 0-2 and lobular inflammation ranges from 0-3, with higher scores indicating more severe hepatocellular ballooning or lobular inflammation.

Event-Free Survival (EFS) at Week 240 as Assessed by Time to First Clinical Event

EFS was assessed by the time to the first clinical event, including progression to cirrhosis on liver biopsy, liver decompensation events, liver transplantation, and all-cause mortality.

Time frame: Week 240

Population: No data was analyzed as the study was terminated and no participants reached the Week 240 timepoint.

Percentage of Participants Who Achieved a ≥ 1-Stage Improvement in Fibrosis According to the Nonalcoholic Steatohepatitis (NASH) Clinical Research Network (CRN) Classification Without Worsening of NASH at Week 48

Fibrosis improvement was defined as ≥ 1-stage decrease from baseline in fibrosis according to the NASH CRN classification. NASH CRN fibrosis stages range from 0 to 4, with higher scores indicating greater fibrosis (0=None, 4=Cirrhosis). Worsening of NASH was defined as ≥ 1 point increase from baseline in hepatocellular ballooning or lobular inflammation according to the Non-Alcoholic Fatty Liver Disease (NAFLD) Activity Score (NAS) criteria. As defined by NAS, hepatocellular ballooning ranges from 0-2 and lobular inflammation ranges from 0-3, with higher scores indicating more severe hepatocellular ballooning or lobular inflammation.

Time frame: Week 48

Population: The Full Analysis Set included all participants who were randomized into the study and received at least 1 dose of study drug.
