A Phase 2 interventional study of [18F]AV-133 in Parkinson's Disease (PD) and Healthy Control Subjects, sponsored by Michael J. Fox Foundation for Parkinson's Research. Recruiting at 1 site in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-21.

The study is a longitudinal, single-center study to assess progression of [18F]AV-133 imaging in PD participants. Participants will be followed for up to 12 months. Approximately 45 PD participants and 5 healthy control participants will be recruited from the ongoing PPMI Clinical 002 study. Participants will be comprehensively assessed at Baseline and follow up according to the Schedule of Activities. Participants will undergo PET imaging assessments with [18F]AV-133. After tracer injection, participants will be imaged on PET cameras at each imaging timepoint-one with the NX camera and one with a standard PET camera-in accordance with the Image Acquisition Protocol (IAP).
4,573 studies on the registry are indexed under Parkinson Disease; 1,086 are open to participants now.
This study's planned enrollment of 50 is above the median of 40 across 3,353 interventional studies indexed under Parkinson Disease.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Male or Female (females must meet additional criteria specified below as applicable)
Females must be of non- or using a highly effective method of 14 days prior to until at least 24 hours after injection of [18F]AV-133
Females of childbearing potential must not be pregnant, breastfeeding or lactating.
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Drug: [18F]AV-133
This protocol is a sub-study under the PPMI Program. It is a longitudinal, single-center study to assess the performance of \[18F\]AV-133 imaging using high and standard resolution PET in individuals enrolled with Parkinson's disease (PD) for up to 12 months.
Comparison of tracer uptake between two cameras using Standardized Uptake Value Ratio (SUVR)
To compare longitudinal change in \[18F\]AV-133 PET SUVR in the striatum and other brain regions acquired with NeuroEXPLORER (NX) camera to that acquired with Siemens Biograph camera.
Time frame: 12 months
