18F-TPP for Membrane Potential Imaging
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to explore how the body processes a new imaging agent called 18F-TPP, which helps visualize cell membrane potential (the electrical charge difference across a cell membrane) using PET scans. The goal is to develop new imaging methods that could enhance the understanding of various health conditions. Individuals who are generally healthy and can undergo PET scans without issues might be suitable candidates for this trial. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new imaging agent.
Do I need to stop taking my current medications for the trial?
The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are taking anticoagulants (blood thinners) or if you cannot safely stop taking aspirin and other NSAIDs (non-steroidal anti-inflammatory drugs).
What prior data suggests that 18F-TPP is safe for membrane potential imaging in humans?
Research shows that 18F-TPP, a substance used for imaging, is currently being tested for safety and effectiveness in people. Although specific information about 18F-TPP remains limited, similar substances with the same base element, Fluorine-18, have been safely used in other medical imaging studies. For instance, Fluorine-18 is often used in PET scans to detect cancer and other conditions and is generally well-tolerated.
Since this study is in its early stages, not all safety aspects of 18F-TPP are known. Early trials like this one aim to identify any side effects. Researchers will closely monitor the safety of 18F-TPP during the study to ensure it is safe for participants.12345Why are researchers excited about this trial?
Researchers are excited about the trial of 18F-TPP because it offers a novel approach to imaging membrane potential in human cells. Unlike traditional imaging methods, 18F-TPP is a PET imaging agent that specifically targets and visualizes the membrane potential (ΔΨT). This could lead to better understanding and diagnostics of various conditions related to cell membrane potential changes, such as heart and neurological diseases. By capturing detailed images of how cells function at a molecular level, this method may pave the way for more precise and effective treatments in the future.
What evidence suggests that 18F-TPP is effective for imaging membrane potential?
Research shows that 18F-TPP, the investigational treatment in this trial, is a promising tool for detecting changes in cell energy levels. Studies have found that it accurately senses when mitochondria, the cell's powerhouses, aren't functioning properly. This is important because mitochondrial problems are linked to many diseases. The radiotracer 18F-TPP detects signals from the cell's energy levels. Early research suggests it could help identify issues in tissues where cells are not functioning well or are dying. This makes 18F-TPP a potential breakthrough for diagnosing certain health conditions.56789

Treatment groups
Experimental Treatment
PET imaging to study the pharmacokinetics of 18F-TPP and develop methods for imaging membrane potential (ΔΨT) in humans. Each scan may or may not have arterial blood sampling for measurement of the time course of radioactivity in the whole-blood, plasma and radiometabolite analysis on selected plasma samples.
