F 18 T807 PET (Positron Emission Tomograph )Scan for HIV Infected & Uninfected
F 18 T807 Tau PET Imaging of Older (>= 40 Years Old) HIV Infected (HIV+) and HIV Uninfected (HIV-) Individuals (IND 123119, Protocol G)
Study Overview
Detailed Description
This protocol will demonstrate the presence of tau fibrils in older HIV+ patients with HIV associated neurocognitive disorders (HAND) compared to cognitively normal HIV+ individuals and HIV- controls.
It will also demonstrate that the phenoconversion from cognitively normal (CN) status to HAND will be closely correlated with neocortical F 18 T807 uptake. In particular, HIV+ patients with MND will have greater tau cortical deposition compared to ANI individuals.
The investigtors hypothesize that in vivo tau imaging will ultimately:
- Demonstrate the presence of tau fibrils in older HIV+ patients with HIV associated neurocognitive disorders (HAND) compared to cognitively normal HIV+ individuals and HIV- controls.
- Demonstrate that the phenoconversion from cognitively normal (CN) status to HAND will be closely correlated with neocortical F 18 T807 uptake. In particular, HIV+ patients with MND will have greater tau cortical deposition compared to ANI individuals.

Sampling Method
Study Population
Description
Inclusion Criteria:
- 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.
Exclusion Criteria:
- 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.
