ClinConnect Summary

This clinical trial is studying a new imaging technique using a special substance called 68GaNOTA-anti-MMR-VHH2. This substance helps doctors see certain immune cells in the body using a type of scan called Positron Emission Tomography (PET). The goal is to improve how we can identify and monitor various health conditions, including cancers in the head and neck, heart issues related to atherosclerosis (narrowing of the arteries), and sarcoidosis, which is a condition that causes inflammation in different parts of the body.

To participate in this study, you need to be at least 18 years old and meet specific criteria based on your health condition. For example, if you have a confirmed cancer in your head and neck, or if you’re scheduled for surgery to remove plaque from your arteries, you might qualify. Participants will undergo imaging tests to help doctors learn more about their conditions. The trial is currently recruiting participants, and it's important to understand that those with certain serious health issues or infections may not be eligible. If you think you might qualify or have questions, it's a good idea to discuss this with your doctor.
