About this study

Official title: The Differential Diagnosis of Parkinson's Disease and Parkinsonism by Positron-emission Tomography With Vesicular Monoamine Transporter Ligand (18F-DTBZ)

The objective of this protocol is to analyze the sensitivity and specificity of 18F-DTBZ PET to the differential diagnosis of Parkinson's disease (PD) and other parkinsonism disorders, including multiple system atrophy (MSA), corticobasal degeneration (CBD), and progressive supranuclear palsy (PSP).

Read the detailed description

40 patients with PD, 40 patients with MSA, 20 patients with CBD, and 20 patients with PSP, will be enrolled. Each evaluable subject involved in this study must fulfill all the inclusion and exclusion criteria according the subject grouping, each subject will have 3 visits in this study, as one screening visit, one imaging visit, and one safety evaluation visit.

Safety measurement will be evaluated by medical history, vital signs, physical examinations,

What participants receive

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

  • 18F-FDGDrug

    During this study, subjects will receive a single i.v. administration of approximately 10 mCi 18F-FP-(+)-DTBZ immediately prior to imaging.

    The proposed dose for this study is based on our phase I study. At the proposed human dose of 10 mCi, the whole body effective dose (ED) will be approximately 680 mrem. The estimated human ED is expected to be comparable to or below the range of other approved brain imaging agents, such as 18F-FDG.

18F-DTBZ for Parkinson's DiseaseExperimentalThis study will compare the brain uptake of 18F- DTBZ in 40 patients with PD, 40 patients with MSA, 20 patients with CBD, and 20 patients with PSP . Each evaluable subject involved in this study must fulfill all the inclusion and exclusion criteria according the subject grouping, each subject will have 3 visits in this study. Safety measurement will be evaluated by medical history, vital signs, physical examinations, laboratory examinations and collecting of adverse events.

What is being measured

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

  1. To analyze the sensitivity and specificity of 18F-DTBZ PET to the differential diagnosis of PD ,PSP,MSA,CBD.

    All subjects that received 18F-FP-(+)-DTBZ for injection.Sensitivity and specificity analysis of VMAT2 imaging will include all subjects for whom there is sufficient data to evaluate the parameter in question.Descriptive statistics will be presented to help detect changes within groups or differences between groups (PD vs. MSA, CBD, PSP). The descriptive statistics will include mean, standard deviation, median, and ranges for continuous variables, and frequency and percent frequency for categorical variables.Mann Whitney test will be used to compare the mean SUVR values between PD and other groups. ROC curve will be used to determinate the diagnostic threshold of SUVR and the sensitivity and specificity of 18F- DTBZ PET in the differentiating PD, MSA, PSP, and CBD. Statistical analysis was performed using a unpaired t test based on one contrast to test a hypothesis of regional abnormal uptakes of 18F-DTBZ in an individual MSA/PSP/CBD patient compared to a PD group.

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 18F-FDG in people with Parkinson's Disease, run by Chang Gung Memorial 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 11 inclusion and 10 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: finished, as of the sponsor's last update on 13 Nov 2013. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To analyze the sensitivity and specificity of 18F-DTBZ PET to the differential diagnosis of PD ,PSP,MSA,CBD. (time frame: 3 years). 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 13 Nov 2013.
