Official title
Center Without Walls for Imaging Proteinopathies With PET (CW2IP2): Phase I Pilot Study of Biodistribution, Metabolism, Excretion and Brain Uptake of 18F-JSS20-183A
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The current protocol is to determine the biodistribution, metabolism, excretion and brain uptake of 18F-JSS20-183A. The goal of this radiotracer is to quantify 4Repeat Tau (4Rtau) protein that is abnormally deposited in the brain of people with a class of neurodegenerative diseases called tauopathies, such as Progressive Supranuclear Palsy (PSP), Corticobasal Syndrome (CBS), syndromes of genetic Frontotemporal Lobar Degeneration (genetic FTLD) as well as participants with Parkinson disease (PD), Alzheimer's Disease (AD) and healthy controls. This multicenter project funded by an NIH U19 grant, is centered at U Pennsylvania (Penn, Grant PI: Robert Mach) in collaboration with U Pittsburgh (Pitt), Yale U, U of California at San Francisco (UCSF) and Washington University in St. Louis (WUSTL). The University of Pennsylvania will act as the sIRB for this multi-center human subjects project and participants will be recruited from all sites.
