PET Imaging of Radiolabeled Anti-HIV-1 Envelope Monoclonal Antibody (VRC01)
University of California, San Francisco
Summary
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.
Description
This will be a single-center pilot study to determine dosimetry and tissue uptake/distribution and pharmacokinetics of 89Zr-VRC01. Up to 18 uninfected and HIV-infected subjects who are either taking or not taking ART will receive a small IV dose of 89Zr-VRC01. After administration of IV 89Zr-VRC01, subjects will undergo up to 4 whole body PET/MR imaging at 2, 6, 24 and 72-120h to determine the pharmacokinetics and radiation dose exposure. The study involves two phases with the second phase only to be performed only if a difference between PET activity in one or more region of interest can be d…
