Description

Summary

This exploratory study investigates how an imaging technique called 68Ga-FAPi-46 PET/CT can determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulates in normal and cancer tissues in patients with cancer. Because some cancers take up 68Ga-FAPi-46 it can be seen with PET. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors (cancer associated fibroblasts). The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers.

Official Title

PET Biodistribution Study of 68Ga-FAPI-46 in Patients With Different Malignancies: An Exploratory Biodistribution Study With Histopathology Validation

Details

PRIMARY OBJECTIVE: I. To define the biodistribution of gallium Ga 68 fibroblast activation protein inhibitor (FAPi)-46 (68Ga-FAPi-46) in normal and cancer tissues of patients with various malignancies. SECONDARY OBJECTIVES: I. To evaluate the degree of 68Ga-FAPi-46 accumulation observed by positron emission tomography (PET) imaging as opposed to the amount of FAP in excised cancer tissue. II. To assess the correlation of 68Ga-FAPI-46 biodistribution with 18F-fluodeoxyglucose (FDG), 68Ga-DOTATATE, or 18F-DOPA (FDOPA), depending on the specific indication. OUTLINE: Patients receive 68Ga-FAPi-46 intravenously (IV) then 20-90 minutes later undergo PET/computed tomography (CT).
