About this study

Official title: Application of 18F-FDOPA PET and Magnetic Resonance Spectroscopy (MRS) in Research of the Association Between HCV Infection and Parkinson's Disease.

The objective of this study is to investigate the evidence of dopaminergic toxicity causing by HCV infection using 18F-FDOPA PET and MRS as imaging biomarkers.

Read the detailed description

Parkinson's disease (PD) is the most common neurodegenerative disorder after Alzheimer's disease. It is characterized by degeneration of the dopaminergic neurons in substantia nigra and striatum, even before the clinical symptoms develop. Although the pathogenesis is still unclear, some viruses have been shown to be associated with acute or chronic parkinsonism. Recent studies have found that Hepatitis C virus (HCV) can replicate in the central nervous system, suggesting a possible link between PD and HCV. At the population and epidemiology level, the HCV infection and PD are strongly associated. At the molecular level, both HCV and PD have in common the overexpression of inflammatory biomarkers. Neuronal toxicity induced by HCV was also demonstrated. The positive association between HCV infection and PD has clinical implications for high endemic HCV areas, including Taiwan.

18F-FDOPA, an analog to L-DOPA, has been used as a positron-emitting compound for PET examination of patients affected by PD. It has been shown that putamen 18F-FDOPA uptakes are reduced by at least 35% at onset of symptoms, making the 18F-FDOPA PET as an imaging biomarker for detecting subclinical and preclinical parkinsonism. Earlier imaging study using magnetic resonance spectroscopy (MRS) to investigate cerebral effect of HCV also showed that chronic HCV infection had elevated choline/creatine ratios, a biomarker indicating inflammatory and infective conditions, in the basal ganglia and white matter.

The objective of this study is to investigate the evidence of dopaminergic toxicity causing by HCV infection using 18F-FDOPA PET and MRS as imaging biomarkers.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 18F-DOPA PETDrug

    One hour later all patient will be injected intravenously with 185 MBq (5mCi) 18F-FDOPA. PET emission data acquisition in 3-dimensional mode will be started at 60 minutes after tracer injection for 30 minutes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. PET imaging

    Visual interpretation will be performed first by two independent readers to record if there is any abnormal 18F-FES accumulation. The presence, number, size, character, and location of suspected lesions will be filed for each patient in this study. The final results will be validated by tissue proof, correlation with other imaging, or follow-up results. Semi-quantitative analysis will be performed for each lesion suspected during visual interpretation. Standardized uptake values (SUV) will be obtained by placing regions of interest (ROIs) around the lesions that are identified on visual analysis. The maximum SUV (SUVmax) will be recorded.

    Volumetric parameters will be performed by placing volume of interests (VOIs) around the suspected lesions. VOIs will be generated using defined fix SUV thresholds or algorithm-generated isocontours. Manual adjustment of VOIs is allowed when non-tumoral tissue is incorrectly included by automatic method.

    Measured: in 3 days

Questions about this trial

What is this clinical trial studying?

A study testing 18F-DOPA PET in people with Hepatitis C and Hepatitis B, run by National Taiwan University Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 17 May 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

PET imaging (time frame: in 3 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 May 2023.
