Using 18F-FAPI PET to Detect Metastatic Disease in Patients That Have Pancreatic Ductal Adenocarcinoma (PDAC)

This is a multi-site, open-label, non-randomized, single dose study to assess the clinical utility of [¹⁸F]FAPI-74 PET/CT in the detection of metastatic disease in individuals with pathologically confirmed pancreatic ductal adenocarcinoma. Following screening, using a standardized administration protocol and dose, participants will undergo [¹⁸F]FAPI-74 PET/CT screening. SOC procedures and interventions will be captured during 3 months +/-14 days post injection. The primary objective is to evaluate the sensitivity and specificity of such [¹⁸F]FAPI-74 PET/CT using a composite SOT panel. The maximum expected duration of the trial is approximately 24 months from first patient screening to last patient SOC follow up. The participants will be followed-up for safety for 24 to 72 hours after the dose of [¹⁸F]FAPI-74 PET/CT.

Inclusion Criteria:

- Male and female adults ≥ 18 years.

- Participants with confirmed PDAC, undergoing staging evaluation for treatment planning.

- Eastern Cooperative Oncology Group (ECOG) performance status ≤2:

- Provided signed, written informed consent obtained prior to any study-related procedures.

- Participants are required to have a ceCT scan of chest, abdomen and pelvis as per standard clinical practice and practice guidelines either 21 days or less prior to entry or planned within 21 days of [¹⁸F]FAPI-74 administration.

- For women who are not postmenopausal (two years of amenorrhea) or surgically sterile (absence of ovaries and/or uterus): agreement to use medically accepted, highly effective methods of contraception (e.g., hormonal implants, combined oral contraceptives, vasectomized partner , during the trial intervention period.

Exclusion Criteria:

- Unequivocal evidence of metastases at the time of enrollment that would preclude surgery as a treatment option.

- Known hypersensitivity to [¹⁸F]FAPI-74.

- Administration of another investigational therapeutic or diagnostic product within 30 days prior to [¹⁸F]FAPI-74 administration.

- Prior administration of a radiopharmaceutical within 10 half-lives of that product from the time of [¹⁸F]FAPI-74 administration.

- Previous cancer diagnosis (except basal cell carcinoma of the skin or in situ carcinoma of the cervix/uterus). Participants treated with curative intent and disease-free for more than 5 years are permitted.

- Hepatic function: T. bili >1.5X ULN or alk phos, ALT, or AST >5X ULN

- Renal function: GFR < 30 mL/min

- Pregnant or breast feeding (a negative pregnancy test is required in women of childbearing potential)

- Inability to undergo the PET/CT scanning procedure.

- Inflammatory bowel disease (Crohn's disease or ulcerative colitis)

- Sarcoidosis

- Treatment, including chemotherapy, radiation or surgery for curative intent of PDAC.
