We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Interventional
Description of intervention(s) / exposure
New PET radiotracer, PI-2620, 185MBq, intravenous. Single administration by certified nuclear medicine technologist. Potential new diagnostic tool. Patients will undergo a single PET scan (duration 60 minutes), the scan will start concurrently with injection of the radiotracer.

Secondary outcome [2] 387898 0
Relationship between PET measures and disease severity.

PET measures (SUV and binding potential) in the basal ganglia will be correlated with disease severity (measured by the PSPRS).
The PSPRS is a clinician administered scale of presence and severity of PSP symptoms
Timepoint [2] 387898 0
Day of scan (PSPRS will be measured approx 1-2 hours prior to PET scan.

Statistical methods / analysis
Image derived measures of uptake and binding in specific brain regions will be collated for different brain regions. Paired, non-parametric statistics will be used to determine differences in PET measures between brain regions.
Correlation analyses will be performed to investigate relationships between PET measurements and disease severity (measured by the PSP rating scale)

Summary
Brief summary
The study will investigate a new PET radiotracer PI-2620 to see if it can visual the tau protein which is observed in the brains of patients with progressive supranuclear palsy (PSP). The tau protein builds up in certain brain areas in patients with PSP, such as the basal ganglia. We hypothesise that PI-2620 will show high levels of uptake in the basal ganglia, indicating the presence of tau.
Patients will undergo a single PET scan, whereby we inject a small amount of the radiotracer. The patient will then be scanned for 60 minutes. The resulting image will then show whether or not the radiotracer binds in the basal ganglia (indicating tau accumulation). The amount of tau in the basal ganglia can be measured from these images and we will then establish whether the levels of tau increase with increasing severity of PSP symptoms.
If successful this radiotracer could be used in the future to help diagnose PSP.
