Investigational Scan (68Ga-FAPI-46 PET/CT) for Imaging of Cancer-Associated Fibroblasts for Localized Pancreatic Ductal Adenocarcinoma

Description

PRIMARY OBJECTIVES:

I. To determine the sensitivity and specificity of gallium Ga 68 FAPi-46 (68Ga-FAPI-46) PET for detection and quantification of cancer-associated fibroblasts (CAFs) in pancreatic ductal adenocarcinoma (PDA).

II. Construct, test and validate a model of surgical benefit or futility in potentially resectable PDA using 68Ga-FAPI-46 PET biomarkers in combination with other biomarkers of disease.

OUTLINE:

Patients receive 68Ga-FAP-46 intravenously (IV), then allow 60 minutes for 68Ga-FAPI-46 uptake. Patients then undergo PET/CT scans over 30 minutes at baseline (before standard of care [SOC] therapy), up to 2 scans approximately 8 weeks apart (at SOC re-staging visits), and a then a scan within 4 weeks of SOC surgical resection, if applicable.

After completion of study treatment, patients are followed up for 5 years.
