Inclusion criteria

* For patients who completed MAESTRO-NAFLD-1, completed the Week 52 visit, and completed the Week 56 visit within 90 days of the Extension Day 1 visit, and are willing to participate in MAESTRO-NAFLD-OLE and provide written informed consent. * For patients who screen failed MAESTRO-NASH, must provide written informed consent for MAESTRO-NAFLD-OLE and must have screened and met all eligibility requirements for MAESTRO-NASH within 90 days of the Extension Day 1 visit for MAESTRO-NAFLD-OLE and have a liver biopsy that is ineligible for MAESTRO-NASH within 6 months of the Extension Day 1 visit. Eligible liver biopsy for MAESTRO-NAFLD-OLE must have one of the following results: * NAS = 3, steatosis 1, ballooning 1, inflammation 1, OR NAS = 3, ballooning 0, with F1B, F2 or F3 * NAS ≥ 4, at least 1 in all NAS components, F1A or F1C, PRO-C3 ≤ 14 (NASH, but ineligible for MAESTRO-NASH) * Compensated NASH cirrhosis based on biopsy at screening of MAESTRO-NASH and baseline of MAESTRO-NAFLD-OLE, including Child Pugh-A (score 5-6), MELD \<12, albumin ≥3.2, and bilirubin \<2 * For patients who screen failed from MAESTRO-NASH OUTCOMES and de novo patients, must have documented CP-A/B (score \<8) NASH cirrhosis (including minimal decompensation) and MELD \<15 unless MELD \>=15 based on non-cirrhotic parameters. MAESTRO-NASH OUTCOMES screen failures must have screened and met all eligibility requirements for MAESTRO-NASH OUTCOMES within 90 days of the Extension Day 1 visit for MAESTRO-NAFLD-OLE .

Exclusion criteria

* A history of significant alcohol consumption for a period of more than 3 consecutive months within 1 year prior to Extension Day 1. * Diagnosis of hepatocellular carcinoma or other carcinomas that may prevent participation in the Extension study. * Chronic liver diseases * Has an active autoimmune disease * Any other condition which, in the opinion of the Investigator, would impede compliance, hinder completion of the study, compromise the well-being of the patient, or interfere with the study outcomes.
