Investigation of Inflammation Using [18F]FZTA
Washington University School of Medicine
Summary
This study involves a Positron Emission Tomography (PET) scan using a new investigational radioactive tracer, \[18F\]-FZTA, to detect inflammation in the brain. The tracer will be tested in healthy younger adults and individuals with Multiple Sclerosis.
Description
The primary objective of this initial IND study is to evaluate the safety of \[18F\]-FZTA for PET imaging of S1P1 expression. The study will begin with whole-body PET dosimetry in healthy adult volunteers to determine the safety and safe radiation dose for a single PET scan in humans. Following this, brain and neck imaging will be conducted in both healthy adult control participants and individuals with multiple sclerosis (both male and female) to characterize \[18F\]-FZTA uptake in the brain. An analysis of the radiolabeled metabolite will also be completed as part of this study.

Inclusion Criteria: * Male or female, any race * Age ≥ 18 years * Capable of providing written informed consent for volunteering to undergo research procedures. * Healthy volunteer or volunteer with a diagnosis of MS established using the revised McDonald criteria (2017) Exclusion Criteria: * Hypersensitivity to \[18F\]FZTA or any of its excipients; * Contraindications to PET, CT, or MRI (e.g., certain incompatible electronic medical devices, inability to lie still for extended periods) that make it potentially unsafe for the individual to participate. * Severe claustrophobia * Women who ar…
Interventions
- Drug[18F] FZTA
Participants will receive a single intravenous bolus injection of 7 ± 20% milliCurie (mCi) of the investigational radiotracer \[18F\]-FZTA. A PET-certified medical professional will prepare and administer the \[18F\]-FZTA. Prior to the administration, the dosage will be assayed in a dose calibrator and diluted with 0.9% sodium chloride (normal saline) up to a total 20 mL syringe volume. Participants will receive a maximum intravenous bolus injection of 7+20% mCi of \[18F\]-FZTA followed by a 10 mL 0.9% sodium chloride (normal saline) flush.
