PET Imaging of Radiolabeled Anti-HIV-1 Envelope Monoclonal Antibody (VRC01)

Description

This is a single center exploratory imaging study involving one intravenous microdose of 89Zr-DFO-VRC01 followed by whole-body PET-MR imaging in HIV infected individuals and healthy volunteers. Imaging data will be obtained from up to four static PE-MR images in order to determine dosimetry and temporal tissue uptake/tissue distribution of 89Zr-DFO-VRC01. This is not a treatment study of the biological activity of 89Zr-DFO-VRC01 to impact HIV persistence.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • 1. Age ≥18 years, and
  • 2. HIV uninfected, or
  • 3. HIV infection, and
  • 4. has an HIV viral load measurement within 12 months of study entry of \>40 copies/mL, and
  • 5. HIV-1 envelope RNA or DNA consensus sequence from peripheral blood suggestive of VRC01 binding activity (HIV infected participants only)
  • 1. Age ≥18 years, and
  • 2. HIV infection, and
  • 3. Initiated a combination ART regimen and has HIV viral load measurements below the detection limit of a clinically approved PCR-based assay (e.g. \<40 HIV-1 RNA copies/mL of blood), or
  • 4. HIV infection, and
  • 5. has an HIV viral load measurement within 12 months of study entry of \>40 copies/mL, and
  • 6. HIV-1 envelope RNA or DNA consensus sequence from peripheral blood suggestive of VRC01 binding activity, or
  • 7. HIV uninfected
  • 1. For patients planning to be imaged on PET-MR scanner, exclusion criteria will include any contra-indication to MRI, including permanent pacemaker, implantable metallic device/ prosthetic, aneurysm clip, non-removable piercing, or severe claustrophobia
  • 2. Any medical condition that would compromise the imaging acquisition, in the opinion of the investigator
  • 3. Patients who have had a study involving radiation within six months of enrolling in this study
  • 4. Patients who are pregnant (female patients of childbearing age will be tested prior to injection of imaging agent - positive test will exclude from participating in the study)
