简要总结
This study will compare the brain uptake of 18F- DTBZ in 20 patients with PD, 20 patients with MSA, 20 patients with PSP, 20 patients with CBS, and 20 patients with VaP, 20 patients with ET, and 10 patients with DT.
详细描述
Study duration is expected to be completed in a period of 4 year. This study is a uncontrolled, open-label, non-randomized, parallel, and cross-sectional study. Total 130 subjects, including 20 patients with PD, 20 patients with MSA, 20 patients with PSP, 20 patients with CBS, 20 patients with VaP, 20 patients with ET, and 10 patients with DT, 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, laboratory examinations and collecting of adverse events.

18F-DTBZ for Parkinson's Disease and parkinsonism
This study will compare the brain uptake of 18F- DTBZ in 20 patients with PD, 20 patients with MSA, 20 patients with PSP, 20 patients with CBS, and 20 patients with VaP, 20 patients with ET, and 10 patients with DT.
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.
干预措施: 18F-DTBZ (Drug)
结局指标
主要结局
Analyzing the differences of monoaminergic degeneration between each group by comparing the SUVR of 18F- DTBZ measured by the VOIs methods in each brain region.
时间窗: 4 years
During this study, subjects will receive a single i.v. administration of approximately 10 mCi 18F-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.
次要结局
- Statistical parametrical mapping will be performed to compare the early-phase and delayed-phase imaging of 18F- DTBZ PET in each group.(4 years)
