Overview

LNTH-1363S is a fibroblast activation protein (FAP) inhibitor radiodiagnostic agent developed for positron emission tomography (PET) imaging. It is a trifunctional small molecule that binds with high affinity to FAP and is radiolabeled with copper-64 (^64Cu), enabling PET imaging of tumors and fibrotic tissues where FAP is overexpressed. The compound has demonstrated favorable safety and biodistribution in first-in-human studies, with primary excretion via the kidneys and minimal off-target uptake. Its main application is in oncology for imaging various cancers including sarcoma and gastrointestinal tract cancers[1][2][5].
