Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an open-label study to evaluate the performance of a novel tau imaging ligand in up to 36 subjects (12 AD, 3 FTD, 3 PSP, 3 CBS, 3 VCI and 12 HV). Subjects will be recruited from the patient population and healthy volunteers of Taiwan residents. This study protocol requires each subject to complete the following components: screening evaluation, brain MRI and 18F-PM-PBB3 PET imaging up to two sessions. The screening procedures will include neuropsychological assessments, vital signs, ECG, physical examinations and laboratory tests. In addition, 18F-AV-45 PET imaging result will be as a part of inclusion criteria to confirm presence of amyloid deposition in patients with clinically diagnosed probable AD or absence of amyloid deposition in FTD, VCI and HV subjects. Furthermore, 18F-AV-133 PET imaging data will also be as a part of inclusion criteria to confirm the diagnosis of PSP and CBS. All subjects will complete clinical assessments and clinical safety tests to ensure the subject is medically stable to complete the study protocol. The screening procedures will occur within 30 days prior to 18F-PMPBB3 PET imaging.
