What the trial is, and whether it could suit you
This is a first in human study that will assess the safety and diagnostic performance of \[18F\]RP-115 (fluorine-18 labeled RP115), a positron emission tomography (PET) agent. This agent has the potential to identify the early changes that occur in the brains of patients with Alzheimer's disease (AD) and frontotemporal dementia (FTD).
