Global Longitudinal Assessment of MASLD Using Magnetic Resonance Elastography ( GOLDMINE ): A Multi‐Center, International Prospective Cohort Study of Imaging Biomarkers in MASLD Clinical Outcomes

BACKGROUND: Metabolic dysfunction-associated steatotic liver disease (MASLD) exhibits marked heterogeneity in fibrosis progression and liver-related outcomes. Liver biopsy is not feasible for longitudinal risk stratification at scale, creating a need for validated non-invasive biomarkers, particularly imaging biomarkers, that can predict clinically meaningful disease progression and liver-related outcomes. AIMS: To describe the design and rationale of the GOLDMINE study, established to determine whether non-invasive imaging biomarkers predict MASLD progression and liver-related clinical outcomes. METHODS: GOLDMINE is an investigator-initiated, multi-centre, international longitudinal cohort enrolling up to 1000 adults with either biopsy-proven MASLD or MASLD cirrhosis across the full fibrosis spectrum. Participants are recruited from 15 sites in the US and 4 international sites (Japan, Singapore and France). At baseline, participants undergo clinical phenotyping, vibration-controlled transient elastography, and advanced magnetic resonance imaging (MRI), including proton-density-fat-fraction and magnetic resonance elastography (MRE). MRI (and biospecimen banking) is repeated at 2-year intervals (years 2 and 4), with annual follow-up visits for up to 10 years. Baseline liver histology is centrally processed, digitized and reviewed by a single expert hepatopathologist; all MRI/MREs are centrally interpreted. RESULTS: The prespecified clinical outcomes include progression to cirrhosis, clinically significant portal hypertension, major adverse liver-related outcomes (ascites, hepatic encephalopathy, portal hypertensive bleeding, liver transplantation/qualification), hepatocellular carcinoma, major adverse cardiovascular events, and all-cause mortality, with independent central adjudication of all events. CONCLUSIONS: GOLDMINE establishes a rigorously phenotyped MASLD cohort integrating centralized histology, advanced MRI-based biomarkers, longitudinal biobanking, and adjudicated outcomes, providing a platform to validate imaging and blood-based prognostic biomarkers in MASLD.
