PHILADELPHIA--(BUSINESS WIRE)--Avid Radiopharmaceuticals, Inc. (Avid), a product-focused molecular imaging company, announced today that enrollment has begun in a proof-of-concept phase I clinical trial investigating Avid’s development compound 18F-AV-133 for imaging patients with movement disorders, including Parkinson’s Disease (PD) and essential tremor, and dementias, including Dementia with Lewy Bodies (DLB) and Alzheimer’s Disease (AD). The compound, used with positron emission tomography (PET) imaging, targets vesicular monoamine transporters (VMAT2) in the brain and may enable more accurate and earlier diagnosis of neurodegenerative diseases. This new imaging compound may thus lead to improved disease management for patients and their caregivers. The study will be initially conducted at the University of Michigan and will involve 30 patients.
