Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Prospective, multi-center, open label, non-randomized clinical trial to assess efficacy of \[18F\]FAPI-74 to detect FAP expressing cells in patients diagnosed with gastrointestinal cancers, including hepatocellular carcinoma, cholangiocarcinoma, gastric, pancreatic and colorectal cancer. The \[18F\]FAPI-74 PET scan will be acquired in patients with proven GI cancers after initial staging using institutional standard methods. The PET scan results will be compared to FAP immunohistochemistry (as the primary objective) and histopathology (as the secondary objective) of the biopsied or resected tissues.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

[18F]FAPI-74 PET/CT

Patients receive \[18F\]FAPI-74 intravenously followed by PET/CT 60 minutes (+/-10minutes) later

Group Type EXPERIMENTAL

[18F]FAPI-74 PET/CT

Intervention Type DRUG

\[18F\]FAPI-74 is a radioactive diagnostic agent indicated for use with Positron Emission Tomography (PET) imaging for the detection of Fibroblast Activation Protein (FAP) positive cancer cells and cancer-associated fibroblasts (CAF) in patients with gastrointestinal cancers.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Confirmed diagnosis of gastrointestinal (GI) malignancy, including hepatocellular carcinoma, cholangiocarcinoma, gastric, pancreatic and colorectal cancer
* Available tissue sample obtained through biopsy or to be obtained through scheduled biopsy and/or surgical resection
* No treatment received between tissue sample taken and \[18F\]FAPI-74 PET
* Anatomic imaging (e.g., CT, MRI) obtained within ≤ 28 days of consent
* Age ≥ 18 years
* Completed informed consent as determined per the IRB of record

Exclusion Criteria

* Pregnant as determined by a pregnancy test as per institutional guidelines for individuals of child-bearing potential
* Declining to use effective contraceptive methods during the study (for individuals of child-producing potential)
* Need for emergent surgery that would be delayed by participation
* Bacterial, viral, or fungal infections requiring systemic therapy, that are expected to impact FAP expression in the opinion of the sponsor or their designee
* Serious co-morbidities and serious nonmalignant disease (e.g., hydronephrosis, kidney failure, liver failure, systemic or local inflammatory or autoimmune diseases or other conditions) that in the opinion of the investigator, physician of record and/or Sofie could compromise subject safety and/or protocol objectives
* Known diagnosis of an autoimmune disorder that is expected to impact FAP expression in the opinion of the sponsor or their designee
* Patients receiving any other investigational agent within the past 28 days
* Breastfeeding. Note: nursing parents are allowed if the potential participant commits to pumping breast milk and discarding it from injection to ≥ 24 hours from the time of the \[18F\]FAPI-74 injection
* Known hypersensitivity to any excipients used in \[18F\]FAPI-74: trace amounts of sodium acetate, sodium ascorbate, ascorbic acid, ethanol, acetonitrile or AlCl.
* Renal or liver function impairment\* \*Defined by liver impairments as AST\>3x the upper limit of normal, ALT\>3x the upper limit of normal, or bilirubin\>1.5x the upper limit of normal. Renal impairment as defined by a creatinine clearance of \>1.5x the upper limit of normal utilizing the Cockcroft Gault formula
