UAB Neuroinflammation in Parkinson's Disease - TSPO-PET Substudy

The primary objective of this substudy is to measure the concentration and the regional brain distribution of activated brain microglia/macrophages using the PET ligand [18F]DPA-714 in participants enrolled in the UAB Neuroinflammation in PD study. The PET tracer [18F]DPA-714 binds to the 18 kDa translocator protein (TSPO, also known as the peripheral benzodiazepine receptor) in the mitochondria of activated microglia/macrophages and provides a non-invasive measure of neuroinflammation. The amount and distribution of [18F]DPA-714 in the brain will be correlated to clinical data acquired through the separate ongoing Neuroinflammation in PD study. The primary objective of this study is to determine if patients with PD have higher levels of neuroinflammation than healthy controls as measured with [18F]DPA-714-PET/MRI.

NCT03457493 Parkinson Disease
MeSH: Parkinson Disease

1 Interventions

Name: DPA-714-PET/MRI

Description: DPA-714-PET/MRI

Type: Drug

Early Parkinson's Disease, DPA-714-PET/MRI Healthy Controls, DPA-714-PET/MRI


Primary Outcomes

Description: Estimates of brain TSPO concentrations measured with PET will serve as a marker for neuroinflammation. TSPO-PET measures will be compared between PD patients and healthy controls. We expect the PD patients to have higher measures of neuroinflammation than healthy controls.

Measure: Comparison of TSPO-PET measures of neuroinflammation between PD patients and healthy controls.

Time: 2 years

Description: The estimates of neuroinflammation measured with TSPO-PET will be correlated with clinical assessments of PD severity and biospecimens collected through the UAB Neuroinflammation in PD study.

Measure: Correlation of DPA-714-PET/MRI with demographics, clinical and biospecimen assessments from Neuroinflammation in PD study

Time: 2 years

Purpose: Diagnostic

Allocation: Non-Randomized
