Brief Summary:
The AURORA study will be conducted to confirm the efficacy and safety of cenicriviroc (CVC) for the treatment of liver fibrosis in adult participants with NASH.

Condition or disease Intervention/treatment Phase
Nonalcoholic Steatohepatitis Drug: Placebo Drug: Cenicriviroc Phase 3

Detailed Description:
The AURORA study will be conducted in 2 parts. Part 1 will examine the surrogate endpoint of improvement in fibrosis of at least 1 stage (nonalcoholic steatohepatitis clinical research network [NASH CRN]) and no worsening of steatohepatitis at Month 12. Participants from Part 1 will continue into Part 2 and additional participants will be newly randomized in Part 2 to determine long-term clinical outcomes composed of histopathologic progression to cirrhosis, liver-related clinical outcomes, and all-cause mortality.

Primary Outcome Measures :
  1. Part 1: Percentage of Participants With Improvement in Fibrosis by at Least 1 Stage and No Worsening of Steatohepatitis on Liver Histology at Month 12 [ Time Frame: Month 12 ]
    Fibrosis stage was evaluated using the Nonalcoholic Steatohepatitis Clinical Research Network (NASH CRN) Fibrosis Staging System with stages: 0=none; 1=perisinusoidal or periportal; 1A=mild, zone 3, perisinusoidal; 1B=moderate, zone 3, perisinusoidal; 1C=portal/periportal; 2=perisinusoidal and portal/periportal; 3=bridging fibrosis; 4=cirrhosis. No worsening of steatohepatitis was defined as no worsening of lobular inflammation or hepatocellular ballooning grade as per scoring in relevant nonalcoholic fatty liver disease activity score (NAS) categories. NAS is a semiquantitative scoring system based on the unweighted sum of: steatosis (0=<5% to 3=>66%), lobular inflammation (0=no foci to 3=>4 foci/200x), and hepatocellular ballooning (0=none to 2=many cells/prominent ballooning) scores. Improvement in fibrosis is a decrease in the NASH CRN fibrosis stage.

  2. Time to First Occurrence of Adjudicated Events in the Full Study Cohort [ Time Frame: From first dose of study drug to onset of first occurrence of the event (Up to approximately 42 months) ]
    Time to first occurrence from Baseline was defined as the number of days from the first dose of randomized investigational product to the onset of the first occurrence of any of the following adjudicated events: death (all cause), histopathologic progression to cirrhosis, liver transplant, model for end stage liver disease (MELD) score ≥15, ascites, hospitalization for onset of: variceal bleed, hepatic encephalopathy, spontaneous bacterial peritonitis. MELD is a scoring system for assessing the severity of chronic liver disease and uses the participant's values for total bilirubin, serum creatinine, and the international normalized ratio for prothrombin time to predict survival. MELD score ranges from 6 (less ill) to 40 (gravely ill) with scores and mortality probability being: Score 40=71.3% mortality; Scores 30-39=52.6% mortality; Scores 20-29=19.6% mortality; Scores10-19=6.0% mortality; Score 9 or less=1.9% mortality.
