Dosimetry, kinetics and test-retest properties of a novel norepinephrine transporter radiotracer [18F]NS12137
This is an early-stage research study, sometimes called a Phase I trial, involving healthy adult men. The main goal is to understand a new substance called [18F]NS12137. This substance is a 'radiotracer,' which means it's a special material that can be seen inside the body using special scanning equipment. Researchers want to find out how much of this substance to use, how it travels and is processed in the body, and if tests using it give similar results when repeated. It's the very first time this particular substance is being given to people, so the study focuses on its safety and how it works in the human body rather than treating a specific illness.
At a glance
What is this study about?
This research study is an important first step in understanding a new substance called [18F]NS12137. Think of it like a special dye or marker that doctors can use to look at how certain parts of the body are working. In this case, it's designed to help scientists trace something called the 'norepinephrine transporter' in the body.
Because this is the very first time this substance will be given to people, the study is focused on safety. Researchers will carefully check how the body handles [18F]NS12137, how much of it to use, and if it gives reliable results when tested multiple times. This kind of early study helps us learn if new substances are safe enough to be used in future research, perhaps to better understand certain health conditions.
While this study doesn't aim to treat a disease, the information gathered from healthy volunteers is crucial. It helps pave the way for future research that might use this new tracing substance to better understand conditions like depression, anxiety, or other brain disorders where the norepinephrine system might play a role. It provides the foundational knowledge needed for any potential future medical applications.
Key takeaways
- An early study testing a new 'tracer' substance for the first time in people.
- Only for healthy adult men.
- Aims to understand how the substance moves through the body and if it gives consistent results.
- Not a treatment for any condition, but important for future medical research.
Who may be eligible?
To be part of this study, you need to be an adult. Specifically, the study is looking for men aged 18 years and older. There is no upper age limit mentioned, so older men may also be able to take part.
It's important to know that this study is for healthy volunteers. This means that if you have certain ongoing health problems or are taking specific medications, you might not be able to participate. The research team will do medical checks to make sure you are healthy enough for the study.
Since this is a very early study and specifically targets men, women are not eligible to take part in this particular research.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Are you a man?
- Are you generally in good health?
- Are you able to attend appointments for medical checks and scans?
What does participation involve?
If you decide to join this study, you would first have a full health check-up to make sure you are suitable. Once confirmed, you would receive a small amount of the new substance, [18F]NS12137, usually given as an injection.
After receiving the substance, you would have special scans, likely PET scans, to see how it moves and is processed in your body. These scans are non-invasive and involve lying still while images are taken. You might need to have blood samples taken at various times to track the substance in your system.
The study also aims to check the 'test-retest' properties, meaning you might have these procedures repeated on a different day to see if the results are consistent. The total duration of your involvement could range from a few visits over a short period to a slightly longer period depending on the specific schedule, but generally, Phase I studies for healthy volunteers are not very long term.

Common questions
What is a 'radiotracer'?
A radiotracer is a special substance, like a tiny beacon, that helps doctors see what's happening inside your body using special scans.
Why is this study only for men?
Because this is the very first time this substance is being given to people, researchers often start with a specific group, like men, to learn about its safety and behaviour before potentially expanding to other groups.
Will I become radioactive?
The amount of the radioactive substance used is very small and designed to decay quickly. You will not become 'radioactive' and any traces will leave your body quickly and naturally.
What does 'Phase I' mean?
Phase I is the earliest stage of human testing. It's mainly about checking if a new substance is safe and how the body handles it, rather than testing if it treats an illness.
Will I get paid for taking part?
Sometimes studies offer payment for your time and travel, but this varies. You should ask the study team directly about any compensation.
