  • "In addition to being imaged with the standard Positron Emission Tomography (PET) camera after the \[18F\]AV133 injection in the PPMI 015 sub study, participants agreeing to a second scan will be imaged with the NeuroEXPLORER (NX) PET camera per this protocol."
  • "The dual PET scans will be completed at baseline, 1-and 2- years follow up."

  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.

About this study

In plain language

This study compares brain scans from a standard PET camera and a higher-resolution PET camera after an injection of the imaging drug [18F] AV-133. It is for people in the PPMI 015 study who may have early signs of Parkinson’s disease. Scans will take place in New Haven, CT, at the start and after 1 and 2 years, with possible extra scans later.

This study is a single-center, longitudinal study and will be conducted at the Institute for Neurodegenerative (INDD) Site in New Haven, CT. This study aims to recruit participants from the ongoing Parkinson's Progression Markers Initiative AV-133 Prodromal Imaging sub study \[PPMI 015\] to obtain a second comparison imaging scan. In addition to being imaged with the standard Positron Emission Tomography (PET) camera after the \[18F\]AV133 injection in the PPMI 015 sub study, participants agreeing to a second scan will be imaged with the NeuroEXPLORER (NX) PET camera per this protocol. This study will enroll approximately 25 participants at the INDD site. The dual PET scans will be completed at baseline, 1-and 2- years follow up. Participants may be asked to undergo further longitudinal scans based on the acquired study data. All participants will have longitudinal clinical, biomarker, and genetic data for correlation analyses to imaging data from the PPMI Clinical study.

Compensation is read from the study's own description and may be missing — always confirm with the study team.
