ListOutcomeTime frameDescription
PrimaryChange From Baseline in Liver Cu Concentration at Week 48 (Treatment Period)Baseline, Week 48 (Treatment Period)Liver biopsy samples were taken for the assessment of liver Cu concentration. Multiple imputation was used to impute missing data at Week 48 due to any reason based on Baseline values.
SecondaryNumber of Participants With Change From Baseline in Nonalcoholic Steatohepatitis Clinical Research Network (NASH CRN) Fibrosis Stage at Week 48 (Treatment Period)Baseline, Week 48 (Treatment Period)
Fibrosis from histology was evaluated by NASH CRN Fibrosis Stage, which was scaled from 0 to 4 stages where Score 0: None; Score 1: Perisinusoidal or periportal - 1a - mild, zone 3, perisinusoidal; Score 1: Perisinusoidal or periportal - 1b - moderate, zone 3, perisinusoidal; Score 1: Perisinusoidal or periportal - 1c - portal/periportal; Score 2: Both perisinusoidal and portal/periportal; Score 3: Bridging fibrosis; and Score 4: Cirrhosis. Higher scores indicated greater fibrosis.
SecondaryNumber of Participants With Change From Baseline in Metavir Fibrosis Score at Week 48 (Treatment Period)Baseline, Week 48 (Treatment Period)
Fibrosis from histology was evaluated by Metavir Fibrosis Score, which was ranged from 0 to 4 where Score 0: No fibrosis; Score 1: Stellate enlargement of portal tract but without septa formation; Score 2: Enlargement of portal tract with rare septa formation; Score 3: Numerous septa without cirrhosis; and Score 4: Cirrhosis. Higher scores indicated greater fibrosis.
SecondaryNumber of Participants With Change From Baseline in Ishak Fibrosis Score at Week 48 (Treatment Period)Baseline, Week 48 (Treatment Period)
Fibrosis from histology was evaluated by Ishak Fibrosis Score, which was ranged from 0 to 6 where Score 0: No fibrosis; Score 1: Fibrous expansion of some portal areas, with or without short fibrous septa; Score 2: Fibrous expansion of most portal areas, with or without short fibrous septa; Score 3: Fibrous expansion of most portal areas with occasional portal to portal (P-P) bridging; and Score 4: Fibrous expansion of portal areas with marked bridging (P-P) as well as portal central (P-C); Score 5: Marked bridging (P-P and/or P-C) with occasional nodules (incomplete cirrhosis); and Score 6: Cirrhosis, probable or definite. Higher scores indicated greater fibrosis.
SecondaryChange From Baseline in Hepatic Collagen Content at Week 48 (Treatment Period)Baseline, Week 48 (Treatment Period)Fibrosis from histology was evaluated by morphometric quantification of hepatic collagen content.
SecondaryChange From Baseline in a-SMA Content at Week 48 (Treatment Period)Baseline, Week 48 (Treatment Period)Fibrosis from histology was evaluated by morphometric quantification of hepatic a-SMA content.
SecondaryNumber of Participants With Change From Baseline in NAS Steatosis Grading Score at Week 48 (Treatment Period)Baseline, Week 48 (Treatment Period)
Steatosis from histology was evaluated by the steatosis component of the NAS, which was ranged from 0 to 3 where Score 0: \< 5% (minimal); Score 1: 5 - 33% (mild); Score 2: 34 - 66% (moderate); and Score 3: \> 66% (severe). Higher scores indicated greater steatosis.
SecondaryChange From Baseline in Hepatic Fat Content at Week 48 (Treatment Period)Baseline, Week 48 (Treatment Period)Steatosis from histology was evaluated by morphometric quantification of hepatic fat content.
SecondaryChange From Baseline in NAS Total Score at Week 48 (Treatment Period)Baseline, Week 48 (Treatment Period)
Inflammation was quantified by the NAS total score. The score is defined as the unweighted sum of the scores for steatosis (0 \[minimal\] to 3 \[severe\]), lobular inflammation (0 \[none\] to 3 \[\>4 foci / 200x field\]), and hepatocellular ballooning (0 \[none\] to 2 \[many\]), thus ranging from 0 (no inflammation) to 8 (severe inflammation), with higher scores indicating more severe disease.
SecondaryTreatment Period: Number of Participants With Treatment-emergent Adverse Events (TEAEs)Day 1 (Treatment Period) up to Week 48 (Treatment Period)
An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. An SAE was an AE that met at least 1 of the following criteria: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization for the AE, persistent or significant disability/incapacity or substantial disruption of the ability to conduct normal life functions, congenital anomaly/birth defect (in the child of a participant who was exposed to the study drug), important medical event or reaction. The TEAEs were AEs with onset on or after the first study drug dose. A summary of all Serious Adverse Events and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.
