F 18 T807 PET (Positron Emission Tomograph )Scan for HIV Infected & Uninfected

2020年9月17日 更新者:Tammie L. S. Benzinger, MD, PhD

F 18 T807 Tau PET Imaging of Older (>= 40 Years Old) HIV Infected (HIV+) and HIV Uninfected (HIV-) Individuals (IND 123119, Protocol G)

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.

详细说明

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.

研究人群

40 HIV+ and 40 HIV- participants will be enrolled.

描述

Inclusion Criteria:

  1. Male or female participants, ≥ 40 years of age.
  2. Testing for HIV status. If positive will be included in the HIV+ group and if negative will be included in the HIV- group.
  3. 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:

  1. 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).
  2. Is deemed likely unable to perform the imaging procedures for any reason.
  3. Has a high risk for Torsades de Pointes or is taking medications known to prolong QT interval.
  4. Has hypersensitivity to F 18 T807 or any of its excipients.
  5. 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.
  6. Severe claustrophobia.
  7. Currently pregnant or breast-feeding.

队列和干预

团体/队列
干预/治疗
F 18 T807
Participants will receive a single intravenous bolus injection of approximately 6.5-10mCi (240-370MBq) of F 18 T807. For those who cannot tolerate the full exam, participants will receive single intravenous bolus injection of approximately 6.5-10mCi (240-370MBq) of F 18 T807.
参与者将接受约 6.5-10mCi (240-370MBq) F 18 T807 的单次静脉推注。 对于无法耐受完整检查的人,参与者将接受单次静脉推注约 6.5-10mCi (240-370MBq) F 18 T807。

IPD 计划说明

As part of this study, we are obtaining data from the participant. We would like to use this data' for studies going on right now as well as studies that are conducted in the future. These studies may provide additional information that will be helpful in understanding cognitive impairment, or other diseases or conditions, including research to develop investigational tests, treatments, drugs or devices that are not yet approved by the U.S. Food and Drug Administration. It is unlikely that what we learn from these studies will have a direct benefit to the participant.
