F 18 T807 PET (Positron Emission Tomograph )Scan for HIV Infected & Uninfected
Completed
Conditions studied: Alzheimer Disease, HIV
In brief
This project will collect quantitative pilot data that will allow the characterization of uptake and binding of 18F-AV-1451 (also known as F 18 T807, also known as T807, also known as 7-(6-fluoropyridin-3-yl)-5H-pyrido\[4,3-b\]indole), a novel tau imaging compound, in older HIV+ individuals with and without HAND and matched HIV uninfected (HIV-) controls. The primary goal is to develop this highly promising tau imaging technique as an biomarker of cognitive decline in HIV+ individuals. The investigators will obtain preliminary data that will support the possibility of detecting early brain pathological changes due to HIV. Data generated from this study will be used for submission of National Institutes of Health (NIH) grants comparing tau deposition in HAND compared to other neurodegenerative disorders. It is hypothesized that specific topographies will help distinguish these neurodegenerative disorders in older individuals.

Who can join
Age: 40 and older. Sex: any. Healthy volunteers: accepted.
You may qualify if…
- Male or female participants, ≥ 40 years of age.
- Testing for HIV status. If positive will be included in the HIV+ group and if negative will be included in the HIV- group.
- Females without documented history of menopause or hysterectomy will undergo a urine pregnancy test 24 hours prior to F 18 T807 drug administration.
You may not qualify if…
- Has any condition that, in the Investigator's opinion, could increase risk to the participant, limit the participant's ability to tolerate the experimental procedures, or interfere with the collection/analysis of the data (for example, participants with severe chronic back pain might not be able to lie still during the scanning procedures).
- Is deemed likely unable to perform the imaging procedures for any reason.
- Has a high risk for Torsades de Pointes or is taking medications known to prolong QT interval.
- Has hypersensitivity to F 18 T807 or any of its excipients.
- Contraindications to PET, PET-CT or MR (e.g. electronic medical devices, inability to lie still for long periods) that make it unsafe for the individual to participate.
- Severe claustrophobia.
- Currently pregnant or breast-feeding.
