Introduction: Fibroblast activation protein (FAP) is an ideal target for tumor imaging and therapy. To enhance tumor uptake and prolong the retention of FAP-targeting agents, we developed JH04, a novel cyclic peptide composed of a FAP-targeting ligand. The objective of this study is to evaluate the specificity, biodistribution, pharmacokinetics, and dosimetry of 68Ga/177Lu-JH04 through preclinical and preliminary clinical investigations, and to compare these findings with those of 68Ga/177Lu-FAP-2286. Methods: The FAP-positive …
