The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment 68Ga-FAPI-46 PET/CT Scan for Pancreatic Cancer?

Research shows that 68Ga-FAPI PET/CT scans can improve tumor detection and staging in pancreatic cancer compared to traditional methods, potentially identifying cancers at an earlier stage.12345

Is the 68Ga-FAPI-46 PET/CT scan safe for humans?

The 68Ga-FAPI PET/CT scan has been used in various studies for imaging tumors and other conditions, and while it shows promise in diagnosing cancers, the safety data specifically for humans is not detailed in the available research. However, it is widely used in clinical settings, suggesting a general acceptance of its safety.36789

How does the 68Ga-FAPI-46 PET/CT scan treatment differ from other treatments for pancreatic cancer?

The 68Ga-FAPI-46 PET/CT scan is unique because it uses a special tracer that targets fibroblast activation protein, which can improve the detection and staging of pancreatic cancer compared to the more commonly used 18F-FDG PET/CT scans. This can lead to better identification of both primary tumors and metastatic lesions, potentially improving treatment planning.123410

What is the purpose of this trial?

This phase II trial tests whether 68Ga-FAPI-46 positron emission tomography (PET)/computed tomography (CT) scan works to image cancer-associated fibroblasts (CAFs) in patients with pancreatic ductal adenocarcinoma (PDA) that has not spread to other parts of the body (localized). CAFs are a type of connective tissue cell that are found within or near cancerous tissue. Many CAFs express a protein called fibroblast activation protein (FAP) that are not found on healthy cells in large amounts. 68Ga-FAPI-46 is a radioactive chemical compound designed to circulate through the body and attach itself to FAP on PDA cells. A PET/CT scan is then used to detect the location of FAP lesions. PET scan is a procedure in which a small amount of radioactive glucose (sugar) is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where the glucose is taken up. Because cancer cells often take up more glucose than normal cells, the pictures can be used to find cancer cells in the body. CT scan is a procedure that uses a computer linked to an x-ray machine to make a series of detailed pictures of areas inside the body. The pictures are taken from different angles and are used to create 3-dimensional (3-D) views of tissues and organs. Combining a PET scan with a CT scan can help make the image easier to interpret. PET/CT scans are hybrid scanners that combine both modalities into a single scan during the same examination. Giving 68Ga-FAPI-46 PET/CT may help doctors improve upon the diagnosis and management of PDA.

Eligibility Criteria

This trial is for adults over 18 with localized pancreatic ductal adenocarcinoma (PDA) who haven't started treatment yet. They should be fit enough for surgery after initial therapy and have an ECOG performance status of 0-2, meaning they can care for themselves. Pregnant women, those allergic to ingredients in the scan compound, or patients needing emergency surgery cannot participate.

Inclusion Criteria

My cancer is localized and planned for surgery after initial treatment.
I can take care of myself and am up and about more than half of the day.
Ability to provide informed consent

Exclusion Criteria

Pregnant or lactating women
I need emergency surgery.
My cancer is confirmed to be metastatic pancreatic ductal adenocarcinoma.

Treatment Details

Interventions

  • Computed Tomography
  • Gallium Ga 68 FAPi-46
  • Positron Emission Tomography
Trial Overview The trial is testing a new type of PET/CT scan using a radioactive compound called 68Ga-FAPI-46 that targets cancer-associated fibroblasts in PDA. The goal is to see if this method improves diagnosis and management by providing clearer images of where the cancer cells are located.

Experimental Treatment
Group I: Diagnostic (gallium GA 68 FAPi-46, PET/CT)Experimental Treatment3 Interventions
Patients receive 68Ga-FAP-46 IV, then allow 60 minutes for 68Ga-FAPI-46 uptake. Patients then undergo PET/CT scans over 30 minutes at baseline (before SOC therapy), up to 2 scans approximately 8 weeks apart (at SOC re-staging visits), and a then a scan within 4 weeks of SOC surgical resection, if applicable.

Findings from Research

In a study of 51 pancreatic cancer patients, [68Ga]Ga-DOTA-FAPI-04 PET/CT demonstrated superior sensitivity compared to [18F]FDG PET/CT for detecting primary tumors (100% vs. 95%), metastatic lymph nodes (96.2% vs. 61.5%), and distant metastases (100% vs. 84%), indicating it may be a more effective diagnostic tool.
The study found that a SUVmax greater than 14.9 on [68Ga]Ga-DOTA-FAPI-04 PET/CT was significantly associated with better progression-free survival rates, suggesting it could serve as an independent prognostic factor for patients with pancreatic cancer.

In a study of 36 patients with suspected pancreatic malignancies, [68Ga]Ga-FAPI PET/CT demonstrated significantly higher sensitivity and radiotracer uptake compared to [18F]FDG PET/CT for detecting primary tumors, lymph node involvement, and metastases.
[68Ga]Ga-FAPI PET/CT also improved TNM staging in 26.1% of cases compared to [18F]FDG, indicating its potential to enhance clinical management decisions in pancreatic cancer.

In a study of 33 patients suspected of having pancreatic cancer, 68 Ga-FAPI-04 PET/MR showed equivalent detection rates for primary tumors compared to 18F-FDG PET/CT, but with significantly higher uptake values, indicating its potential for better tumor characterization.
68 Ga-FAPI-04 PET/MR was more effective in detecting suspicious lymph node metastases compared to 18F-FDG PET, while the latter was better at identifying liver metastases, suggesting that combining these imaging techniques could enhance overall diagnostic accuracy.
