Inclusion Criteria: * Males and non-pregnant, non-lactating females between 18 - 75 years of age inclusive, based on the date of the screening visit. * Previous history or presence of 2 out of 4 components of metabolic syndrome (obesity, dyslipidemia, elevated blood pressure, elevated fasting glucose) or type 2 diabetes. * FibroScan measurement \> 8.5 kPa \[kilopascal\]. * Biopsy-proven NASH. Must have had a liver biopsy obtained ≤ 180 days prior to randomization with fibrosis stage 2 to 3 and a non-alcoholic fatty liver disease (NAFLD) activity score (NAS) of ≥ 4 with at least a score of 1 in each of the following NAS components: * Steatosis (scored 0 to 3), * Ballooning degeneration (scored 0 to 2), and * Lobular inflammation (scored 0 to 3). Exclusion Criteria: * Weight loss \> 5% in the 3 months prior to screening until randomization or from the time of the diagnostic liver biopsy until randomization, whichever is longer. * Presence of cirrhosis on liver biopsy (stage 4 fibrosis). * Type 1 or uncontrolled Type 2 diabetes. Other inclusion and exclusion criteria may apply.

Outcomes

Primary Outcomes

Effect of Efruxifermin (EFX) vs Placebo on Fibrosis Regression in Participants With Metabolic Dysfunction-associated Steatohepatitis (MASH)-Associated Stage 2 or 3 Fibrosis (F2 or F3)

Proportions of subjects in EFX vs placebo groups with improvement in liver fibrosis, defined as ≥ 1 stage NASH Clinical Research Network \[CRN\] fibrosis score (score ranges from 0 to 4, increasing with fibrosis severity), and no worsening of steatohepatitis (no increase in NASH Activity Score \[NAS\], which ranges from 0 to 8 and is the sum of scores of steatosis, lobular inflammation, and hepatocyte ballooning), at Week 24

Time frame: 24 Weeks

Secondary Outcomes

Proportion of Subjects Who Achieve Improvement in Liver Fibrosis ≥ 1 Stage and no Worsening of Steatohepatitis at Week 96

Proportions of subjects in EFX vs baseline groups who achieve improvement in liver fibrosis (decrease of ≥ 1 stage in NASH CRN fibrosis score) and no worsening of steatohepatitis (no increase in NAS for ballooning, inflammation, or steatosis) at Week 96

Time frame: 96 Weeks

Proportion of Subjects Who Achieve Resolution of Steatohepatitis and no Worsening of Liver Fibrosis at Week 24 and Week 96

Proportions of subjects in EFX vs placebo groups who achieve resolution of steatohepatitis (defined as a NAS of 0-1 for inflammation, 0 for ballooning, and any value for steatosis) and no worsening of liver fibrosis (determined by the NASH CRN criteria)

Time frame: 24 and 96 weeks

Proportion of Subjects Who Achieve Improvement in Liver Fibrosis ≥ 1 Stage at Week 24 and Week 96

Proportion of subjects in EFX vs placebo groups who achieve improvement in liver fibrosis (decrease ≥ 1 stage in NASH CRN fibrosis score)

Time frame: 24 and 96 Weeks

Change From Baseline in Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) at Week 24 and Week 96

Change from baseline in Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) in EFX vs placebo groups The Homeostatic Model Assessment of Insulin Resistance, HOMA-IR, is a calculated index that estimates insulin resistance based on fasting glucose and insulin levels. Higher values indicate greater insulin resistance. \< 1.0: Normal insulin sensitivity 1.0-1.9: Mild insulin resistance 2.0-2.9: Moderate insulin resistance \> 2.9: Severe insulin resistance

Change From Baseline in Enhanced Liver Fibrosis (ELF) Score at Week 24 and Week 96

Change from Baseline in Enhanced Liver Fibrosis (ELF) Score in EFX vs placebo groups The Enhanced Liver Fibrosis (ELF) score is a non-invasive blood test that assesses the risk of liver fibrosis and its progression. Lower risk (\<9.8): Suggests a lower risk of advanced liver fibrosis. Mid risk (9.8-11.2): Indicates a moderate risk of disease progression. Higher risk (≥11.3): Suggests a higher risk of developing cirrhosis or liver-related events
