About this trial
This is a Phase 2 study evaluating the positron-emitting radiopharmaceutical 18F-mFBG as an imaging agent for quantification of the effect of neurodegenerative diseases on myocardial sympathetic innervation. Effectiveness of 18F-mFBG imaging of the heart will be judged in terms of the quantitative difference between results for subjects with Lewy body and non-Lewy body neurologic disease as compared to historical data for healthy control subjects.

Treatment groups
Trial outcomes
Primary outcomes
Cohort 1: Quantify the extent and degree of global and regional reduced 18F-mFBG myocardial uptake on PET/CT (or PET/MR) of subjects with known or presumed Lewy body disease (Parkinson's disease (PD) and Lewy body dementia (LBD)).
All image data will be analyzed to develop and validate quantitative measures of global and regional myocardial uptake of 18F-mFBG at two times between injection and 60 minutes post-administration. The data from subjects without Lewy body disease will be used in comparisons with equivalent results for Lewy body disease subjects. Results for subjects imaged in this study will also be compared with historical data from imaging of healthy control subjects without heart disease.
Secondary outcomes
Cohorts 1 and 2: Quantify 18F-mFBG whole-body activity distribution in Lewy body disease subjects (voxel, regional, and global basis) at 30-minutes post-administration
Normalized uptake measurements (counts/voxel/MBq administered) determined from Lewy body disease subjects will be used for quantitative comparisons to non-Lewy body disease and historical healthy control subject scans.
Cohort 1 and 2: 18F-mFBG PET quantitative assessment at 60 minutes
18F-mFBG myocardial activity in Lewy body disease subjects (voxel, regional, and global basis) at 60-minutes post-administration compared to non-Lewy body disease subjects.
Cohorts 1 and 2: Global myocardial 18F-mFBG activity in Lewy body disease subjects compared to non-Lewy body disease subjects.
Global myocardial 18F-mFBG activity in Lewy body disease subjects at 30-minutes post-administration, as a proportion of total-body activity, compared to non-Lewy body disease subjects.
