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.

Fibroblast activation protein (FAP) is a cell surface protein that is highly expressed on the surface of cancer-associated fibroblasts (CAFs) present in the tumor microenvironment of most epithelial cancers, whereas limited expression of FAP is observed in normal tissues. In some cancers of mesenchymal origin, notably sarcoma and mesothelioma, FAP expression has also been observed on the tumor cells themselves. Given the restricted expression profile, FAP is a promising target for peptide-targeted radionuclide imaging and therapeutic agents.

Phase 1 of this study is designed to evaluate the safety and establish the recommended intravenous (IV) Phase 2 dose (RP2D) for \[177Lu\]Lu FAP 2286 monotherapy in participants with FAP expressing solid tumors.

Phase 2 is designed to evaluate the safety and efficacy of \[177Lu\]Lu FAP 2286 as monotherapy in participants with pancreatic ductal adenocarcinoma (PDAC), non-small cell lung cancer (NSCLC), and breast cancer (BC) and in combination with chemotherapy in participants with untreated PDAC or relapsed NSCLC.

Participants in both Phase 1 and 2 will be selected for treatment with \[177Lu\]Lu FAP 2286 based on \[68Ga\]Ga FAP 2286 imaging for determining tumor FAP expression.

To evaluate the feasibility and potential clinical utility of serial AI-augmented computed tomography (CT) imaging and longitudinal blood biobanking in individuals with glycemically-defined new-onset diabetes (gNOD) and elevated pancreatic cancer risk (ENDPAC score ≥3), with the aim of determining whether this approach enables earlier detection of pancreatic ductal adenocarcinoma (PDA) relative to symptom-driven diagnosis

The purpose of this study is 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. 

The purpose of this study is to assess the effectiveness of [18F]FAPI-74 in detecting FAP expressing cells in patients diagnosed with gastrointestinal cancers, including hepatocellular carcinoma, cholangiocarcinoma, gastric, pancreatic and colorectal cancer.  

The primary purpose of this study is to evaluate diagnostic performance of 68Ga-PSMA-dual contrast (gadavist and gadoxetate) PET/MRI OR PET/CT for HCC using surgical histopathology (either resection, transplant or biopsy specimens) or LI-RADS® categorization as gold standard.

The purpose of this study is to evaluate the feasibility and diagnostic performance of 68Ga PSMA-dual contrast PET/MRI for detection and staging of Hepatocellular Carcinoma (HCC), and to compare it with standard-of-care (SOC) imaging. Additionally, this study aims to identify the biologic correlates of biomarkers derived from 68Ga PSMA-dual contrast PET/MRI with histopathology features and PSMA immunostaining of HCC.

Aims, purpose, or objectives:

1. Evaluation of quantitative biomarkers derived from simultaneous time-of-flight FDG PET-MRI/MRCP for assessment of response to neoadjuvant therapy in borderline resectable PDAC.
2. Evaluate the comparative performance of blood and FDG PET-MRI/MRCP based biomarkers for assessment of response to neoadjuvant therapy in borderline resectable PDAC.

The purpose of this study is to examine the relationship of ctDNA status and FDG PET/MRI findings with other clinicopathologic variables and standard staging examinations. We will develop a multivariable model combining ctDNA and FDG PET/MRI biomarkers to predict treatment response and survival. In addition, we will define the quantitative thresholds for early chemotherapy switch in patients who do not respond to first-line chemotherapy.

The purpose of this study is to evaluate an artificial intelligence (AI) algorithm, developed for detection of pancreatic ductal adenocarcinoma (PDA), on contrast enhanced abdomen CT scans requested by referring providers as a part of clinically indicated examinations.    

Evaluation of TOF FDG PET-MRE for identification of predominantly fibrotic small bowel strictures in Crohn’s disease.

The purpose of this study is to examine the utility of 68GaFAPI-46 PET/CT imaging in adult patients with biopsy-proven Pancreatic Ductal Adenocarcinoma (PDA) who have no prior treatment for their PDA and who are expected to undergo surgical resection following NAT.
