Phase II study to assess in vivo imaging of MMR-expressing macrophages in cardiac sarcoidosis using 68Ga-NOTA-Anti-MMR-VHH2 Positron Emission Tomography (PET).
This study is looking into a new type of scan for people with heart sarcoidosis. Heart sarcoidosis is a condition where tiny clumps of inflammatory cells, called granulomas, grow in the heart, which can affect its function. The new scan uses a special substance, called 68Ga-NOTA-Anti-MMR-VHH2, which is designed to light up specific cells involved in inflammation. By doing this, doctors hope to get a clearer picture of where the sarcoidosis is active in the heart. This research aims to see how well this new scan works compared to current methods, if it's safe, and if it can help monitor how well treatments are working. The ultimate goal is to improve how heart sarcoidosis is diagnosed and managed.
At a glance
What is this study about?
This research is looking at a new way to get detailed pictures of the heart in people who have a condition called cardiac sarcoidosis. Cardiac sarcoidosis is when little collections of inflammatory cells, known as granulomas, build up in the heart muscle. These granulomas can disrupt the heart's normal function.
The study uses a special type of scan called a PET scan. For this scan, a new ‘tracer’ substance, called 68Ga-NOTA-Anti-MMR-VHH2, is given. This tracer is designed to specifically attach to and highlight certain inflammatory cells that are thought to be involved in cardiac sarcoidosis. By doing this, doctors hope to see exactly where the sarcoidosis is active in the heart. This could potentially help in diagnosing the condition more accurately and tracking how it responds to treatment.
Throughout the study, doctors will be checking several things. They want to see how many people with known or suspected cardiac sarcoidosis have these specific areas light up on the new scan. They will also look at how this new scan compares to other scans or tests that are currently used, such as different types of PET scans or MRI scans of the heart. Safety is also very important, so researchers will carefully monitor for any unexpected effects, often called side effects, from the new tracer and the scan itself. The overall aim is to explore if this new imaging technique could become a valuable tool for patients with cardiac sarcoidosis.
Key takeaways
- This study uses a new type of scan to find active inflammation in heart sarcoidosis.
- It aims to improve how doctors diagnose and track the condition.
- The scan uses a special substance that highlights specific inflammatory cells.
- Researchers will compare this new scan with current methods.
- Safety and potential side effects will be carefully monitored.
- Participation is voluntary, and your current treatment won't change due to the study.
Who may be eligible?
This study is open to adults aged 18 and over who have been diagnosed with cardiac sarcoidosis. This diagnosis could have been made either by looking at a tissue sample under a microscope (histology) or by a doctor using generally accepted medical guidelines, which suggest it's highly likely to be cardiac sarcoidosis, even without a tissue sample.
Both men and women can take part in this study. The most important thing is that participants have a confirmed or highly probable diagnosis of cardiac sarcoidosis affecting their heart. Your doctor will be able to explain if your specific situation fits these requirements.
- Are you 18 years old or older?
- Have you been diagnosed with cardiac sarcoidosis, either by a tissue sample or by a doctor following specific guidelines?
- Are you able to attend appointments for imaging scans and other study procedures?
- Are you willing to potentially receive an experimental tracer for a scan?
This is a guide only — the research team will confirm whether you can take part.
What does participation involve?
Taking part in this study means you would undergo a special PET scan using the new tracer, 68Ga-NOTA-Anti-MMR-VHH2. This scan will involve receiving a small, safe amount of the tracer, which will then allow images of your heart to be taken. You would also likely have some blood tests and other routine checks to make sure you are suitable for the study and to monitor your health. If you are already having treatment for sarcoidosis, this would continue as normal during the study, and doctors might compare the new scan results with scans you've had before or will have in the future. The total duration of your involvement would depend on the specific procedures and follow-up required.

Common questions
What is cardiac sarcoidosis?
Cardiac sarcoidosis is a condition where small clumps of inflammatory cells, called granulomas, grow in your heart muscle, which can affect how well your heart works.
What is a PET scan?
A PET scan is a type of imaging test that uses a special substance to show how your organs and tissues are working. In this study, it helps find active inflammation in the heart.
What is the new tracer being tested?
The new tracer is called 68Ga-NOTA-Anti-MMR-VHH2. It's a special substance designed to attach to certain inflammatory cells in your heart, helping them show up on the PET scan.
Will being in the study change my current treatment?
No, this study is designed to see how well the new scan works. Your usual treatment for cardiac sarcoidosis would continue as normal unless your doctors decide otherwise for your health.
Is the new tracer safe?
The safety of the tracer is an important part of the study. Researchers will carefully check for any side effects, but like all medical substances, there's always a chance of unexpected reactions.
