Non-invasive blood and imaging tests for metabolic liver disease

Non-Invasive Biomarkers for Metabolic Liver Disease (NIMBLE) Study 2.0 - An FNIH Biomarkers Consortium Study

Foundation for the National Institutes of Health · NCT07122700

This project tests whether blood tests and imaging scans can diagnose and stage metabolic-associated steatohepatitis (MASH) and liver fibrosis in adults with metabolic risk factors.

What this trial studies

NIMBLE is a multi-year, observational collaboration led by the Foundation for the National Institutes of Health with FDA and academic and industry partners to standardize and validate non-invasive biomarkers for metabolic liver disease. The project collects blood-based, vibration-controlled transient elastography (VCTE), and other imaging data across two planned stages to generate evidence supporting regulatory qualification. The effort aims to show that these non-invasive measures can identify and stage MASH with fibrosis and could serve as alternatives to liver biopsy. Data are pooled and analyzed to compare biomarker performance against histology and clinical outcomes.

Who should consider this trial

Good fit: Adults aged 18–74 with metabolic dysfunction—such as physician-diagnosed type 2 diabetes or meeting metabolic syndrome criteria—who can attend in-person blood and imaging visits are the intended participants.

Not a fit: People without metabolic risk factors, those with liver disease from other known causes, or those unable to attend the U.S. clinical sites are unlikely to benefit from these tests.

Why it matters

Potential benefit: If successful, these tests could reduce the need for liver biopsy and make diagnosis and staging of MASH safer and more accessible.

How similar studies have performed: Previous studies have shown promise for individual tools like VCTE, MRI measures, and serum panels, but large-scale regulatory qualification efforts like NIMBLE are relatively new.

Exclusion Criteria:

1. Known history or evidence of other forms of chronic liver disease other than MASLD/MASH including but not limited to viral hepatitis B or C, autoimmune liver disease, primary biliary cholangitis, primary sclerosing cholangitis, Wilson disease, hemochromatosis, drug-induced liver disease, conditions involving bile duct obstructions, liver cancer, past history of HCC or HCC treatment, listed for or history of liver transplantation, prior resection of liver, etc.
2. Current or past evidence of decompensated liver disease defined by overt ascites that is clinically obvious and requires diuretic therapy, overt encephalopathy requiring therapy or history of variceal hemorrhage
3. Circulating Alanine aminotransferase (ALT)\> 5xULN
4. Ongoing or recent (within the last two years prior to screening) consumption of significantly greater than moderate amounts of alcohol.

   * A standard alcoholic drink is any drink that contains about 14 g of pure alcohol, such as 12 fluid ounces of regular beer 8-10 fluid ounces of malt liquor or flavored malt beverages such as hard seltzer 5 fluid ounces of table wine 3-4 fluid ounces of fortified wine such as sherry or port 2-3 fluid ounces of cordial liqueur or aperitif 1.5 fluid ounces (a single jigger or shot) of brandy, cognac, or distilled spirits such as gin, rum, tequila, vodka, whiskey, etc.
   * Significantly greater than moderate alcohol consumption is defined as on average over a 2-year period prior to screening:

   Women
   * \>1 standard drink per day and/or
   * \>14 standard drinks per week Men
   * \>2 standard drinks per day and/or
   * \>21 standard drinks per week in men
