- NCT07217704
- Lead Sponsor
- SOFIE
- Brief Summary
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.

- Primary Outcome Measures
Name Time Method Sensitivity and specificity for detection of distant metastatic disease (M1) using a composite SOT as reference From enrollment to the end of treatment after 3 month follow up To evaluate the diagnostic performance of \[¹⁸F\]FAPI-74 in determining the presence or absence of metastatic disease (M1) in individuals with pathologically confirmed gastric, gastroesophageal junction or esophageal cancers, compared to a composite SOT
- Secondary Outcome Measures
Name Time Method Incidence and severity of adverse events using CTCAE v5. 24-72 hours post-injection To assess the safety profile of \[¹⁸F\]FAPI-74.
Sensitivity and specificity for the localized detection of peritoneal metastases From enrollment to the end of treatment after 3 month follow up To evaluate the diagnostic performance of \[18F\]FAPI-74 PET/CT for detecting peritoneal metastatic disease
Comparative sensitivity and specificity between [18F]FAPI-74 and [¹⁸F]FDG PET/CT for detection of M1 disease using a composite SOT as reference From enrollment to the end of treatment after 3 month follow up To compare clinical accuracy of \[18F\]FAPI-74 PET/CT imaging to that of \[¹⁸F\]FDG PET/CT, for participants who have had this performed, for detection of metastatic disease.
Cohen's kappa for pairwise evaluation of inter- and intra-reader agreement From enrollment to the end of treatment after 3 month follow up To assess inter-and intra-reader variability in image interpretation of the presence of metastatic disease
