Spots Global Cancer Trial Database for First-in-Human Assessment of Safety, Biodistribution and Pharmacokinetics of 18F-Fluoro-1-Naphthol (18F-4FN) for PET Imaging

Study Description

Brief 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

Detailed 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 radiopharmaceutical localized to known or clinically-suspected tissues or regions of inflammation mediated by innate immune-related adverse events (irAE). Another exploratory objective is to determine if a time point other than one-hour post injection will yield clinically meaningful improvements to imaging data.
