Study of [68Ga]FAPI-46 PET in Patients With Pancreatic Ductal Carcinoma

About

Brief Summary

This is a prospective, multi-center, single arm, open label, non-randomized study to evaluate the ability of [68Ga]FAPI-46 to detect FAP expressing cells in patients with resectable or borderline resectable PDAC. The [68Ga]FAPI-46 PET scans will be acquired after initial staging using institutional standard methods. If the participant is prescribed neoadjuvant therapy, a second [68Ga]FAPI-46 PET scan will be performed within 21 days prior to planned surgical resection. This will be followed by histopathology and IHC analyses and comparison to resected PDAC tumor specimens.

Inclusion Criteria:

Pathologically confirmed pancreatic ductal adenocarcinoma
Treatment-naïve
Staged as resectable or borderline-resectable
Planned to undergo surgical resection or to receive neoadjuvant therapy (i.e., chemotherapy, radiation therapy, or combination) and subsequent possible surgical resection
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
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 patient safety and/or protocol objectives.
Known diagnosis of autoimmune disorders
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 [68Ga]FAPI-46 injection.
Known hypersensitivity to any excipients used in [68Ga]FAPI-46: trace amounts of sodium acetate sodium ascorbate and/or hydrochloric acid
