First-in-Human Assessment of Safety, Biodistribution and Pharmacokinetics of 18F-Fluoro-1-Naphthol (18F-4FN) for PET Imaging
M.D. Anderson Cancer Center
Summary
18F-4FN represents a novel PET agent for imaging inflammation. Acute inflammatory signaling through the TLR axis recruits neutrophils and macrophages to inflammatory sites. Both cells activate the production of high energy reactive oxygen species/reactive nitrogen species (RONS), setting off a cascade that can be leveraged to detect the presence of these inflammatory cells by molecular imaging. 18F-4FN is efficiently oxidized by high energy RONS, leading to retention and accumulation in human neutrophil-like cells in vitro, and at the sites of acute inflammation in vivo. Like 18F-FDG, 18F-4FN clears rapidly through the kidney at 1 hr following i.v. injection
Description
OBJECTIVES: Primary Objective: The primary objective of this first-in-human (FIH) study is to determine the safety, biodistribution, and dosimetry profile of a novel positron emission tomography (PET) imaging tracer, 4-\[18F\]fluoro-1-naphthol (\[18F\]4FN), which specifically targets reactive oxygen species (ROS). A currently proposed indication for this radiopharmaceutical (RP) is to non-invasively quantify inflammation by PET/CT imaging. Exploratory Objectives: One exploratory objective is to identify preliminary efficacy signals from PET/CT images indicating that the new radiopharmaceut…
