Summary

This trial will study the brain chemistry of people with opioid use disorder and those without, using PET/CT scans.

Who is the study for?
Adults aged 18-60 with opioid use disorder (OUD) are eligible for this trial. It includes those who have had an overdose treated with naloxone in the past year, those without such a history, and healthy controls without OUD or recent opioid use. Participants must be on stable medication for OUD for at least 30 days and provide informed consent.
What is being tested?
The study is testing [18F]PI-2620 PET/CT imaging to measure tau protein uptake in the brain across three groups: individuals with OUD who've overdosed, those with OUD who haven't overdosed, and healthy controls.
What are the potential side effects?
While not explicitly listed, potential side effects may include discomfort from the injection of the tracer [18F]PI-2620, reactions to PET/CT scan contrast materials if used, and general risks associated with radiation exposure from imaging.

Trial Design

1Treatment groups
Experimental Treatment
Group I: Tau PET/CTExperimental Treatment1 Intervention
PET/CT imaging will be used to evaluate the uptake of tau in the brain using the investigational radiotracer \[18F\]PI-2620. Each subject will have one \[18F\]PI-2620 positron emission tomography/computed tomography (PET/CT) scan performed. Participants will undergo approximately 30 minutes of static PET scanning of the brain and body starting approximately 45 minutes post injection of \[18F\]PI-2620. All images will be corrected for scatter and measured photon attenuation and reconstructed using standard reconstruction techniques. Standardized uptake value ratio (SUVr), the ratio of regional to reference uptake, will be calculated with cerebellum as reference, where NFTs are generally not present in neurodegenerative disorders, hence likely not in OUD. Subjects in all three groups undergo a brain MRI including a structural MRI functional reactivity to an episodic memory task, and undergo a comprehensive neurocognitive battery.
