Image Characteristic and Longitudinal Follow up of 18F-PMPBB3 (APN-1607) PET for Progressive Supranuclear Palsy

September 8, 2020 updated by: Chang Gung Memorial Hospital
The study will enroll 20 PSP and 8 normal subjects with complete neurological examination, 18F-PMPBB3 (APN-1607) PET and MRI assessment. To explore: (1) whether 18F-PMPBB3 (APN-1607) can detect the 4R tau protein in the brain of PSP patients; (2) whether 18F-PMPBB3 (APN-1607) can distinguish the clinical characteristics of PSP; (3) Whether the distribution of tau deposition is related to disease severity, progression, and prognosis.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Progressive supranuclear palsy (PSP), also known as Steele-Richardson-Olszewski syndrome, has a similar incidence in men and women. The pathophysiology of PSP is remaining unclear, but it is known to be related to the abnormal accumulation of 4R tau protein in the brain. Recently, new generation of novel radiotracer 18F-PMPBB3 (APN-1607), which can be labeled with 4R PHF-tau without significant off-target binding, has been successfully developed. The study will enroll 20 PSP and 8 normal subjects with complete neurological examination, 18F-PMPBB3 (APN-1607) PET and MRI assessment. To explore: (1) whether 18F-PMPBB3 (APN-1607) can detect the 4R tau protein in the brain of PSP patients; (2) whether 18F-PMPBB3 (APN-1607) can distinguish the clinical characteristics of PSP; (3) Whether the distribution of tau deposition is related to disease severity, progression, and prognosis. The research results will help to understand the potential of 18F-PMPBB3 (APN-1607) as a biomarker for diagnosis and therapeutic assessment tool for progressive nuclear paralysis as well as other tau proteinopathy.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

What is the study measuring?

Primary Outcome Measures

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
