This is a single-center drug distribution and pharmacokinetic study of a single microdose of 18F-raltegravir given to 10 HIV-infected subjects who are either taking or not taking a raltegravir-containing ART regimen. After administration of IV 18F-raltegravir, subjects will undergo PET/MRI in order to determine the distribution of radiolabeled drug through the lymphoreticular system and other tissues throughout the entire body.

HIV-1-infection, Raltegravir Potassium, 18F-Raltegravir

  • Timothy J Henrich, MD
    My laboratory/research group specializes in immunmodulatory, cytoreductive chemotherapeutic and stem cell transplantation approaches to HIV-1 cure. We are also involved in the design and implementation of novel nano/microtechnologies and PET-based imaging approaches to characterize viral reservoirs.
