64Cu-FBP8 PET-CT Imaging for Blood Clots
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new imaging method to detect fresh blood clots in the lungs, known as pulmonary embolism (PE), and in the deep veins, called deep venous thrombosis (DVT). The process uses a special PET-CT scan with a new tracer, 64Cu-FBP8 (a fibrin binding probe), to help spot these clots more clearly. Individuals recently diagnosed with a significant pulmonary embolism confirmed by a CT scan, and who can receive the tracer injection within 72 hours, might be suitable for this study. As a Phase 1 trial, this research aims to understand how this new imaging method works in people, offering participants the opportunity to be among the first to experience this innovative approach.
Do I need to stop my current medications for the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, if you are using medications like vasopressors or tPA, you may be excluded from the study, so it's best to discuss your medications with the trial team.
What prior data suggests that this PET-probe is safe for imaging blood clots?
Research has shown that the 64Cu-FBP8 PET-CT scan is generally easy for people to handle. In earlier studies, researchers closely monitored the safety of this new imaging tool. Participants did not report any major side effects. Important health signs, such as heart rate and breathing, were checked before and after the scans, and no significant changes were found.
Additionally, early studies in humans have shown that this scan has low radiation exposure and exits the body quickly through the kidneys. This rapid clearance is a positive indicator for safety. Overall, the findings suggest that 64Cu-FBP8 is safe for detecting blood clots in conditions like pulmonary embolism and deep vein thrombosis.12345Why are researchers excited about this study treatment?
Most treatments for acute pulmonary embolism, like anticoagulants, work by preventing further clotting. But 64Cu-FBP8 is different because it uses a special PET-CT imaging technique to directly visualize and characterize blood clots. This radiotracer binds specifically to fibrin, a protein found in blood clots, allowing doctors to see clots clearly and assess their size and severity. Researchers are excited about this approach because it could lead to more accurate diagnosis and personalized treatment planning, potentially improving patient outcomes by tailoring therapies to the individual's specific condition.
What evidence suggests that 64Cu-FBP8 PET-CT Imaging is effective for detecting blood clots in pulmonary embolism and deep venous thrombosis?
Research has shown that the 64Cu-FBP8 probe is a promising tool for detecting blood clots. In this trial, participants with acute pulmonary embolism will receive the 64Cu-FBP8 probe and undergo PET-CT imaging. The probe targets fibrin, a key protein in clots, enhancing visibility in PET-CT scans. Studies have demonstrated its effectiveness in identifying clots in conditions such as pulmonary embolism (PE) and deep vein thrombosis (DVT). The probe has successfully located these clots in imaging, aiding in more accurate diagnosis and potential treatment of these conditions.16789

Are You a Good Fit for This Trial?
This trial is for adults over 18 with a recent diagnosis of pulmonary embolism or deep vein thrombosis confirmed by CT scans. Participants must be able to lie flat for 45 minutes and have adequate kidney function. Pregnant women, those exceeding weight limits for PET imaging, or individuals exposed to high levels of radiation in the past year are excluded.Inclusion Criteria
