This clinical trial is focused on studying a liver condition known as Nonalcoholic Steatohepatitis (NASH), which is a type of liver disease that occurs when fat builds up in the liver, causing inflammation and damage. The study will use a special imaging technique called Fibroblast Activation Protein Imaging to assess the stage of liver fibrosis, which is the scarring of liver tissue. The imaging involves a substance known as 68Ga-FAPI-46, which is a radiopharmaceutical precursor. This means it is a type of drug that uses a small amount of radioactive material to help doctors see how much scarring is present in the liver.
The purpose of the study is to determine if the uptake of 68Ga-FAPI-46 in the liver, as seen on a PET/CT scan (a type of imaging test that helps visualize organs and tissues), varies according to different stages of liver fibrosis. These stages range from mild to severe, with stage 4 being cirrhosis, which is the most advanced form of liver scarring. Participants in the study will have already undergone a liver biopsy, which is a procedure where a small piece of liver tissue is removed and examined to confirm the presence of NASH.
Throughout the study, the intensity of 68Ga-FAPI-46 uptake will be measured at the sites where liver biopsies were taken. This will help researchers understand how the imaging results correlate with the actual fibrosis stage determined by the biopsy. The study will also explore if this imaging method can detect other areas of fibrosis or inflammation in the body, and potentially even cancer, as this tracer has shown promise in identifying various types of cancer. The study is expected to continue until August 2027.
