ABSTRACT

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.

1. Introduction

Metabolic dysfunction‐associated steatotic liver disease (MASLD) is recognized as the most prevalent cause of chronic liver disease worldwide [1, 2]. MASLD is estimated to affect approximately one‐third of the adult population in the United States (US) and is currently the second leading indication for liver transplantation [3, 4]. Its prevalence is strongly associated with metabolic syndrome, obesity and type 2 diabetes mellitus [5, 6]. Moreover, MASLD can lead to progressive liver disease, including cirrhosis and hepatocellular carcinoma (HCC) [7, 8]. Although advanced fibrosis and cirrhosis have been identified as the main risk factors for liver‐related mortality [9, 10], the natural history of MASLD and factors associated with its progression remain incompletely understood. For example, MASLD exhibits substantial heterogeneity in disease severity and fibrosis progression, and only a subset of adults with MASLD ultimately develop liver‐related complications [7, 10].

For many years, liver biopsy has been considered the gold standard for staging liver fibrosis in MASLD. However, liver biopsy is not suitable for use as a population‐wide screening tool because of its cost, limited availability and associated risks [11]. Thus, identification of those individuals with MASLD who are at risk for progressive liver disease and liver‐related morbidity and mortality through non‐invasive means is a major priority [12]. To date, biomarkers of interest have been identified based on the current understanding of the pathogenesis of MASLD and include markers of oxidative stress, inflammation, hepatocyte apoptosis and hepatic fibrosis. Furthermore, newer technologies are now being applied to MASLD biomarker development, including lipidomics, proteomics, metabolomics, metagenomics and genomics, which may contribute to the identification of novel biomarkers of disease [13]. Although most of these biomarkers cannot reliably identify individuals with significant fibrosis and steatohepatitis, others, such as chemical shift–encoding magnetic resonance imaging (MRI)–derived proton density fat fraction (PDFF) and magnetic resonance elastography (MRE), yield high sensitivity and specificity for identifying steatohepatitis and liver fibrosis, respectively [14, 15]. Both PDFF and MRE can be useful not only for diagnostic purposes but also for ongoing monitoring of disease progression and response to treatment [16, 17, 18, 19].

Here we present the protocol for the Global Longitudinal Assessment of MASLD using Magnetic Resonance Elastography (GOLDMINE) study, an international multicenter prospective cohort study enrolling adults with biopsy‐proven MASLD and MASLD‐related cirrhosis. This study will facilitate the needed evaluation of the following: (1) Further elucidation of the natural history of MASLD and its different histological subtypes; (2) Understanding of MASLD disease variation occurring in different segments of the population by enrolling a racially and ethnically diverse group of patients; (3) Characterization of the prognostic factors for progression of MASLD and liver‐related clinical outcomes; (4) Development of novel predictive non‐invasive imaging and non‐imaging biomarkers of MASLD progression, and for longitudinal follow‐up of MASLD. (5) Interpretation of dynamic changes in non‐invasive markers, such as changes in liver stiffness on MRE between years 1 and 2, in relation to long‐term clinical outcomes.

2. Methods

2.1. Overview

GOLDMINE is an investigator‐initiated, multicenter, international longitudinal study that includes a well‐characterized cohort of up to 1000 adults with either biopsy‐proven MASLD or MASLD‐related cirrhosis (Figure 1). The full spectrum of MASLD is represented, including all stages of fibrosis. This is a clinicopathologic condition‐based study designed primarily to allow the compilation of data and collection of specimens for the study of the epidemiology and natural history of MASLD. Participants undergo contemporaneous MRI (PDFF and MRE) at the time of enrollment, followed by two subsequent MRI studies at 2‐year intervals. Biobanking occurs at baseline and at 2‐year intervals to coincide with advanced MRI imaging. Histologic assessment of baseline liver biopsies is systematically performed by one central experienced liver pathologist. Participants return annually for up to 10 years of follow‐up. The sample size calculation is outlined in the Data S1.

2.2. Study Objectives

The primary objective of the GOLDMINE study is to create a multicenter longitudinal cohort to investigate whether non‐invasive imaging biomarkers predict disease progression and clinical outcomes in MASLD. Secondary objectives include: (1) to define clinically significant changes in non‐invasive imaging biomarkers and compare the diagnostic accuracy of MRI and ultrasound‐based modalities, (2) create a biospecimen bank [serum, plasma, urine, DNA and liver tissue] suitable for development of prognostic non‐imaging biomarkers and (3) to provide a resource for ancillary studies of MASLD pathogenesis including genomic, proteomic and lipidomic characterization.

2.3. Organization and Oversight

Coordination of the GOLDMINE study is performed by the MASLD Research Center at the University of California, San Diego (La Jolla, California, US). Responsibilities of the coordinating site include creation of the protocol, defining standard operating procedures, data management of all centralized MRI data and management of the web‐based REDCap database. GOLDMINE participants are enrolled from 15 sites in the US and 4 international sites. International sites are in Japan, Singapore and France. Participating GOLDMINE sites are shown in Figures 2 and 3. Site principal investigators are experienced hepatologists and clinical researchers with expertise in MASLD (Table 1).

2.4. Ethical Practice and Confidentiality

Prior to implementation of this protocol, the principal investigator must have the protocol and consent form approved by the Institutional Review Board for Human Research (IRB) at his/her institution. Once a candidate for the GOLDMINE study entry has been identified, details are carefully discussed with the participant. The participant is asked to read and sign the IRB‐approved consent form. There is a separate consent for the collection, storage and use of DNA for genetic research. Consent for screening and Health Insurance Portability and Accountability Act (HIPAA) authorization to disclose protected health information with the GOLDMINE Study must be obtained from the participant prior to initiating any data collection. HIPAA authorization forms are prepared according to the clinical center IRB requirements and guidelines. Data is held within the registry in an anonymized form to avoid identifiable data transfer or processing outside of the participant's care team at the recruiting center. All laboratory specimens, data, reports and other records that are part of the study data collection and entry materials are identified by a coded number to maintain subject confidentiality.

2.5. Biorepository

All biosamples are processed at participating sites according to standardized protocols. Samples are then stored at the Altman Clinical and Translational Institute, which is a state‐of‐the‐art biobanking facility at the University of California San Diego (La Jolla, California, USA).

2.6. Study Inclusion and Exclusion Criteria

Adults (age ≥ 18 years) with biopsy‐proven MASLD or MASLD‐related cirrhosis are eligible for study inclusion. Liver biopsy must be performed within 180 days prior to study enrollment but is not required for participants with MASLD‐related cirrhosis. MASLD is defined by steatosis involving at least 5% of hepatocytes on routine stains in the absence of evidence of any other acute or chronic liver disease. Cirrhosis may be defined based on histology or a clinical diagnosis of cirrhosis by a board‐certified gastroenterologist based on the combination of imaging, physical examination and laboratory findings.

Patients meeting any of the following criteria were excluded from the study: significant alcohol consumption (defined as ≥ 14 drinks/week for men or ≥ 7 drinks/week for women) within the previous 2‐year period; underlying liver disease including hepatitis B, hepatitis C, hemochromatosis, Wilson's disease, alpha‐1 antitrypsin deficiency, glycogen storage disease, autoimmune hepatitis and cholestatic or vascular liver disease; clinical or laboratory evidence of secondary causes or chronic conditions associated with hepatic steatosis including nutritional disorders, human immunodeficiency virus (HIV) infection and use of steatogenic drugs such as amiodarone, glucocorticoids, methotrexate, l‐asparaginase and valproic acid; major systemic illnesses; contraindications to MRI, including metallic implants, claustrophobia and body circumference exceeding the imaging chamber capacity; pregnancy or attempting to become pregnant. All patients undergo etiologic tests at baseline, including hepatitis B surface antigen, hepatitis C antibody, HIV antigen/antibody, ceruloplasmin and alpha‐1 antitrypsin. Clinically significant portal hypertension (CSPH) is not an exclusion criterion and is evaluated for at both baseline and at annual follow‐up. Inclusion and exclusion criteria are further detailed in Table 2.

2.7. Central Histologic Interpretation and Digitization of Liver Biopsies

Liver biopsy is required for study enrollment in all patients, unless there is a clinical diagnosis of cirrhosis confirmed by the site principal investigator. All liver biopsies are accessioned, processed and stained (haematoxylin & eosin and trichrome) through a centralized process overseen by AcelaBio (San Diego, CA, USA) to minimize variation of slide preparation. High‐resolution images from whole slides are digitized and transferred to an imaging management system to facilitate central pathology secondary review and interpretation.

One expert hepatopathologist reviews all liver biopsies for GOLDMINE participants, and the central pathologist confirms that the biopsy is not exclusionary. This process was chosen given concerns regarding interobserver variability in assessment. The standardized central GOLDMINE histology form is included in the Data S1 and includes capture of many exploratory features.

2.8. Baseline and Annual Follow‐Up

All GOLDMINE participants present for a baseline evaluation and follow‐up visits are scheduled at one‐year intervals after enrollment. An overview of study procedures is included in Figure 1.

A comprehensive dataset is collected at each visit (Table 3). The following assessments occur at every study visit: (1) medical history including data on key events or intervention, surgeries, hospital admissions, new diagnoses of co‐morbidities; (2) medication history: specific medications queried include those taken for the treatment of liver disease (i.e., resmetirom and/or glucagon‐like peptide‐1 receptor agonists), diabetes, insulin resistance, hypertension and hyperlipidemia; (3) physical examination including vital signs, anthropometrics and general and liver‐specific signs (jaundice, spider angiomata, palmar erythema, hepatomegaly, splenomegaly, asterixis); (4) standardized questionnaires to assess alcohol use history, including the Alcohol Use Disorders Identification Test (AUDIT) and Skinner Lifetime Drinking history at baseline and the interim drinking history (AUDIT‐C) at annual follow‐up visits; (5) screening etiologic tests for chronic liver disease at baseline and phlebotomy for routine fasting laboratory tests (haematology, glucose and insulin, clinical chemistry, hepatic panel, glycated haemoglobin and lipid profile); (6) ultrasound and vibration‐controlled transient elastography (VCTE) with controlled attenuation parameter (CAP) performed by a certified technician according to the manufacturer's protocol; (7) documentation of any esophagogastroduodenoscopy (EGD) findings performed for routine clinical care; and (8) documentation of any additional liver biopsies performed as part of standard of care or during participation in other research trials.

Liver biopsy is only performed at baseline per protocol; if subsequent liver biopsies are performed for clinical care purposes, this information is collected. Endoscopy is not included in the GOLDMINE protocol, but esophagogastroduodenoscopy (EGD) data is collected if performed for clinical care.

b

Required serum etiologic tests include hepatitis B surface antigen, hepatitis C antibody, alpha‐1‐antitrypsin, ceruloplasmin, ferritin and iron indices, anti‐mitochondrial antibody (AMA), anti‐smooth muscle antibody (ASMA) and anti‐nuclear antibody (ANA).

c

According to a central standardized operating procedure. Biobanking specimens collected include plasma, serum, whole blood and urine.

d

Women of reproductive age undergo a urine pregnancy test prior to magnetic resonance imaging. MRE protocol is further outlined in the Table S1.

In addition to the above procedures, the following are performed at baseline and every 2 years, for 2 additional occurrences (years 2 and 4): MRI per study protocol and biospecimen banking (serum, plasma, urine, DNA and liver tissue samples if available). Blood samples are drawn in a fasting state. Standardized methods are utilized for serum, plasma, peripheral blood mononuclear cells and DNA isolation that allow for maximal preservation of banked specimens and storage in designated −80°C freezers. We estimated that approximately 20% of the patient population at any stage of MASLD (no fibrosis, mild/moderate fibrosis, advanced fibrosis) will exhibit fibrosis progression within a 2‐year span [20], which was our reasoning for obtaining MRI and biospecimens at 2‐year intervals during this 10‐year study.

2.9. MRI and MRE With Central Imaging Repository and Interpretation

MRI examinations include four research sequences (three imaging sequences and one single‐voxel spectroscopy sequence), allowing for the measurement of liver fat fraction and newer candidate MRI‐based biomarkers for future MASLD studies (Figure 4 and Table S1). MRE is performed according to previously described methods on commercially available software and hardware (Developed by Resoundant Inc., Rochester, MN and available from the major MRI manufacturers). No more than a maximum of 180 days is permitted to elapse between liver biopsy and imaging assessments, including ultrasound, VCTE and MRI‐based imaging. Image acquisition at expiration is required. To assess sequence repeatability, two sequences per subject, block randomized, will be run three times. All MRIs are transferred and interpreted by the central imaging team at Resoundant Inc. (Rochester, MN, USA). MRI images are transferred to Mayo via AMBRA, a secure, cloud‐based, medical imaging transfer and storage solution. AMBRA performs client‐side metadata de‐identification before upload. For analyses comparing ultrasound with MRI‐based modalities, paired examinations obtained within the prespecified 180‐day imaging window will be used, and site‐related heterogeneity in ultrasound acquisition will be accounted for analytically by stratifying analyses according to center (central coordinating site vs. other sites).

All outcomes, including all deaths, are reviewed by an adjudication committee according to a standardized protocol.

b

Elastography measures of cirrhosis include LSM ≥ 20 kPa (VCTE) and/or LSM ≥ 5 kPa (MRE).

Progression to cirrhosis is defined by any of the following: histopathology, clinical evidence of cirrhosis (combined radiologic and clinical criteria), non‐invasive and elastography measures of cirrhosis, or development of CSPH. MALO is defined by any of the following: clinically apparent ascites requiring treatment (with paracentesis, diuretics and/or transjugular intrahepatic portosystemic shunt), hepatic encephalopathy, grade 2 or above according to the West Haven criteria and requiring treatment documented by a gastroenterologist, progression to large gastric or oesophageal varices and/or ‘red‐wale’ signs or endoscopic treatment, portal hypertension‐related upper gastrointestinal bleeding identified by EGD and requiring hospitalization, including events of bleeding from oesophageal varices or gastric varices, and liver transplantation or qualification for liver transplantation, defined as Model for End‐Stage Liver Disease (MELD) score ≥ 15 on at least 2 consecutive occasions at least 2 weeks apart. HCC must be confirmed by histology or by characteristic appearance on multiphasic, contrast‐enhanced ultrasound, computed tomography (CT), or MRI.

We will collect cardiovascular events, including coronary heart disease and/or cerebrovascular accident (stroke). In particular, we will assess major adverse cardiovascular events (MACEs), which will be composed of coronary events (unstable angina, myocardial infarction, or coronary intervention or surgery), ischemic or hemorrhagic stroke, heart failure, or cardiovascular death.

3.2. Adjudication of Clinical Outcomes

All clinical outcomes and deaths are reviewed by an adjudication committee. The adjudication committee is an independent committee composed of three physician members who have expertise in hepatology. For outcomes including progression to cirrhosis and MALOs, sites provide the central adjudication committee with a clinical description of the event, including signs and symptoms and information on treatment (e.g., discharge summary, hospital notes and relevant hospital records related to the event). Pertinent laboratory results (with reference ranges, if available, and including MELD scores), imaging results, and pathology reports are also provided to the committee. All deaths in the study are reviewed by the adjudication committee to determine if liver‐related, cardiovascular‐related, or related to another cause.

4. Discussion

We have presented the protocol for GOLDMINE, which is a prospective, international multi‐center study including up to 1000 adults with biopsy‐proven MASLD enrolled across 20 sites in North America, Europe and Asia. Numerous strengths of the GOLDMINE study design include: (1) enrollment of a diverse patient population from sites across multiple continents; (2) central histologic interpretation for study entry by a single experienced liver pathologist; (3) standardized prospective biobanking; (4) novel imaging protocol with central imaging interpretation of all MRI‐based studies; (5) extended follow‐up of all participants up to 10 years after initial enrollment; and (6) adjudication of all liver‐related outcomes by a central adjudication committee comprised of experienced hepatologists.

Due to these innovative aspects of the study protocol, the GOLDMINE study affords outstanding opportunities to explore the natural history of MASLD and its different histological subtypes. In particular, MRE outperforms VCTE and ultrasound‐based elastography techniques (point shear‐wave elastography and 2D shear‐wave elastography) for staging liver fibrosis [21]. An individual‐participant‐data meta‐analysis of 798 participants with MASLD showed that MRE achieves higher sensitivity and specificity, with areas under the receiver operating characteristic curve for detecting significant fibrosis (≥ F2), advanced fibrosis (≥ F3) and cirrhosis (F4) within the range of 0.92–0.94 [15]. Moreover, MRE is less affected by technical limitations such as obesity, ascites, or challenging anatomy, and demonstrates superior intra‐ and inter‐observer reproducibility compared to ultrasound‐based methods [22, 23]. In addition, MRE can better identify changes in liver stiffness than VCTE, in which changes in kPa do not follow a linear pattern and are associated with higher intra‐ and inter‐observer variability [24].

We will also be able to better understand variation in MASLD disease burden occurring in different segments of the population by enrolling a racially and ethnically diverse group of patients. For example, the US exhibits a high burden of cardiometabolic risk factors, with an obesity prevalence of 45.6% in women and 41.5% in men [25], and a diabetes prevalence of 15.8% [26]. In contrast, other populations, such as the Japanese population, may exhibit lower prevalence, with obesity (BMI ≥ 25 kg/m2) prevalence of 27.2% in men and 10.6% in women [27], and a diabetes prevalence of about 8% [28]. Specific differences in ethnicities across the US are also expected. For example, Hispanic individuals constitute approximately 45%–50% of the population in Southern California but around 9% of the population in Pennsylvania [29]. Also, the Hispanic population from Southern California is predominantly of Mexican heritage, while in Pennsylvania, the Hispanic population is smaller and more diverse in origin. Considering that Hispanics carry a higher frequency of patatin‐like phospholipase domain–containing protein 3 (PNPLA3) I148M genetic risk variant, more severe phenotypes are expected in this population [30]. Therefore, these differing exposures may help to identify comparative risks associated with cardiometabolic risk factors and specific susceptibility among races and ethnicities.

We expect to further characterize the prognostic factors that drive progression of MASLD, ranging from simple steatosis to advanced fibrosis, cirrhosis and liver‐related events. Using large, well‐phenotyped and diverse cohorts, we will evaluate how clinical, metabolic, lifestyle and genetic determinants interact over time to influence these trajectories. In parallel, we aim to develop and validate novel predictive non‐invasive biomarkers of MASLD progression by integrating cutting‐edge technologies, including genomics, metagenomics, metabolomics, lipidomics and proteomics. Finally, we will also investigate innovative imaging technologies for the non‐invasive longitudinal follow‐up of MASLD, enabling dynamic monitoring of disease activity and treatment response.

In conclusion, the GOLDMINE study establishes a rigorously designed, prospective, international cohort of adults with biopsy‐proven MASLD across all fibrosis stages, integrating centralized histologic assessment, advanced MRI‐based phenotyping and longitudinal clinical follow‐up. By combining MRE—one of the most accurate and reproducible non‐invasive tools for fibrosis assessment—with detailed clinical, laboratory and histologic data, GOLDMINE is uniquely positioned to delineate the natural history of MASLD across the full spectrum of disease severity.
