About this trial

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 gastric, gastroesophageal junction or esophageal cancer. 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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Male and female adults ≥ 18 years.

Participants with confirmed gastric, esophageal or gastroesophageal malignancy undergoing staging evaluation for treatment planning.

Eastern Cooperative Oncology Group (ECOG) performance status ≤2.

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

Disqualifiers

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 diagnostic or therapeutic 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.

Time frame
From enrollment to the end of treatment after 3 month follow up

Secondary outcomes

1

Incidence and severity of adverse events using CTCAE v5.

To assess the safety profile of \[¹⁸F\]FAPI-74.

Time frame
