Trial Outcomes & Findings for PET Imaging in MCI Following ADT for PCa (NCT NCT02061345)

NCT ID: NCT02061345

Last Updated: 2023-12-07

Results Overview

The outcome measure is the increased uptake of 11-Carbon Peripheral Benzodiazepine Receptor-28 (\[11C\]PBR28) biomarker by activated microglia of patients demonstrating significant MCI with the primary endpoint of \[11C\]PBR28 uptake measured as a standardized uptake value (SUV)
