Imaging Inflammation With Alcohol Use Disorder: an [18F]NOS Study

Status Recruiting

Clinical Trial Summary

Study to enroll up to 90 individuals, those with an alcohol use disorder (AUD) (up to n=60) and non-dependent healthy volunteers (HV) (up to n=30). PET/CT imaging will be used to evaluate brain and whole-body inflammation using the investigational radiotracer [18F]NOS. All participants will have one [18F]NOS positron emission tomography/ computed tomography (PET/CT) scan performed.

Clinical Trial Description

The Investigators plan to enroll up to 90 individuals in this study, which will enroll individuals with an alcohol use disorder (AUD) (up to n=60) and non-dependent healthy volunteers (HV) (up to n=30). PET/CT imaging will be used to evaluate brain and whole-body inflammation using the investigational radiotracer [18F]NOS. All participants will have one [18F]NOS positron emission tomography/computed tomography (PET/CT) scan performed, unless this has been performed as part of another study. AUD participants enrolled in a companion treatment study #851593 "A Randomized, Double-blind Placebo-Controlled Study of Ibudilast for Treating Alcohol Use Disorder" will be asked to undergo a second [18F]NOS PET scan after the initiation of the study treatment. For each PET/CT scan, patients will undergo approximately 60 minutes of dynamic scanning starting at the time of injection of [18F]NOS. PET/CT imaging sessions will include an injection of ≤ 6.5 mCi (approximate range for most studies is anticipated to be 3.5-6.5 mCi) of [18F]NOS. Data will be collected to evaluate uptake of [18F]NOS in the brain and other organs (e.g., lungs, heart, and liver), and measurements will be compared between groups. Each participant will undergo a 1-hour brain MRI to measure brain inflammatory markers using GluCEST and spectroscopic imaging, unless this has been performed as part of another study and deemed acceptable by an investigator. On the PET day, a blood sample will be collected to measure established peripheral inflammatory biomarkers to be correlated with [18F]NOS uptake. AUD participants who are enrolled in the companion treatment study will be asked to undergo a second brain MRI, PET/CT scan, and blood draw for inflammatory markers after the initiation of treatment. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
