A Phase 2b, Dose-Ranging, Randomized, Double-Blind, Placebo-Controlled Trial Evaluating the Safety and Efficacy of GS-6624, a Monoclonal Antibody Against Lysyl Oxidase-Like Molecule 2 (LOXL2), in Subjects With Advanced Liver Fibrosis But Not Cirrhosis Secondary to Non-Alcoholic Steatohepatitis (NASH)

Overview
Brief Summary
The primary objective of this study is to evaluate whether SIM (formerly referred to as GS-6624) is effective at preventing the histologic progression of liver fibrosis and the clinical progression to cirrhosis in participants with NASH.
It will consist of 2 phases:
- Randomized Double-Blind Phase
- Open-Label Phase (optional)

Inclusion Criteria
- •Adults with chronic liver disease due to NASH defined as macrovesicular steatosis involving \> 5% of hepatocytes on a liver biopsy with associated lobular inflammation
- •Stage 3-4 fibrosis by Ishak score on a liver biopsy
- •Exclusion of other causes of liver disease including viral hepatitis and alcoholic liver disease
- •Must have aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 10 x Central Laboratory Upper Limit of Normal (clULN)
- •Must have serum creatinine \< 2.0 mg/dL
- •A negative serum pregnancy test is required for females of childbearing potential
- •All sexually active females of childbearing potential must agree to use a protocol recommended method of contraception during intercourse throughout the study and for 90 days following the last dose of study medication
- •Lactating females must agree to discontinue nursing before starting study treatment
- •Males, if not vasectomized, are required to use barrier contraception (condom plus spermicide) during heterosexual intercourse from the screening through the study completion and for 90 days following the last dose of study drug.
Exclusion Criteria
- •Pregnant or breast feeding
- •Cirrhosis of the liver
- •Any history of hepatic decompensation including ascites, hepatic encephalopathy or variceal bleeding
- •Weight reduction surgery in the past 5 years
- •Positive for hepatitis C virus (HCV) RNA
- •Positive for HBsAg
- •Alcohol consumption greater than 21oz/week for males or 14oz/week for females
- •Positive urine screen for amphetamines, cocaine or opiates (i.e. heroin, morphine) at screening.
- •Clinically significant cardiac disease
- •History of malignancy, other than non-melanomatous skin cancer, within 5 years prior to screening
Outcomes
Primary Outcomes
Change From Baseline in MQC on Liver Biopsy
Time Frame: Baseline to Week 96
Event Free Survival (EFS) Using Kaplan-Meier
Time Frame: Baseline up to the time of progression to cirrhosis or last dose date (maximum: 240 weeks in the Blinded Phase), which ever occurred first
The EFS was the primary clinical efficacy endpoint and was assessed by the time to progression to cirrhosis. Participants were considered to have become cirrhotic if they had a post-baseline biopsy consistent with cirrhosis or developed overt signs and symptoms of cirrhosis. All overt signs and symptoms went through an adjudication process and were confirmed before they were considered for the EFS analysis.
Secondary Outcomes
