Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Accuumulation of [18F]SMBT-1 in the brain regions of AD and PSP patients as well as in ACs such as standardized uptake value (SUV), as well as pharmacokinetic parameters such as K1, k2, k3, k4, binding potential and distribution volume. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1) Sensitivity and specificity to discriminate AD and PSP patients goups from ACs within this study. Correlations of brain [18F]SMBT-1 accumulation to the cognitive abilities of AD and PSP patients. 2) Correlations between [18F]SMBT-1 accumulation and general cognitive abilities and [11C]PiB. 3) Changes in vital signs (blood pressure, heart rate, SPO2) and blood tests (blood cell counts and blood chemistry) | — |
