About this study
Official title: 18F-DTBZ PET and Multi-modal MRI in the Patients With Vascular Parkinsonism: Investigating the Correlation Between Cerebral Structural and Functional Changes, and Clinical Manifestation
Forty patients with clinically diagnosed VP and 20 healthy subjects will be enrolled in the study. Each evaluable subject involved in this study must fulfill all the inclusion and exclusion criteria and each subject will have 3 visits in the study, as one screening visit, one imaging visit, and one safety evaluation visit.
Read the detailed description
Study duration is expected to be completed in a period of 3 year. The study will enroll 40 patients with VP and 20 healthy subjects.
This neuroimaging study includes the 18F-FP-(+)-DTBZ PET, MRI structure images, diffusion tensor imaging, susceptibility weighted imaging, resting state and gait-related imagery task functional MRI. Each evaluable subject involved in this study must fulfill all the inclusion and exclusion criteria according the subject group, each subject will have 3 visits in this study. Safety measurement for 18F-FP-(+)-DTBZ will be evaluated by medical history, vital signs, physical examinations, laboratory examinations and collecting of adverse events.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
18F-DTBZDrug
During this study, subjects will receive a single i.v. administration of approximately 10 mCi 18F-FP-(+)-DTBZ immediately prior to imaging. The compound is labeled with fluorine 18F that decays by positron (β+) emission and has a half life of 109.7 min. The principal photons useful for diagnostic imaging are the 511 keV gamma photons, resulting from the interaction of the emitted positron with an electron.
The proposed dose for this study is based on the 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
The difference of specific uptake ratio (SUR) of 18F-DTBZ between disease and control group
Measured: 3 years
Secondary outcomes (1)
The correlation between parameters from different imaging modalities and the severity of motor symptoms or cognition in disease group.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing 18F-DTBZ in people with Vascular Parkinsonism, 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 3 inclusion and 12 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 31 Jan 2018. 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?
The difference of specific uptake ratio (SUR) of 18F-DTBZ between disease and control group (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 31 Jan 2018.
