Details and patient eligibility

About

This project will target patients with highly clinically suspected or histopathology diagnosed hepatocellular carcinoma (HCC) using targeted GPC3-specific imaging agents (e.g. , Iodine-131-aGPC3-Scfv) for integrated SPECTCT imaging, to evaluate the pharmacokinetics distribution of the targeted drug in patients with hepatocellular carcinoma (HCC) by low-dose integrated diagnosis and treatment (i.e. , Iodine-131-RRB- imaging, to determine the metabolism, safety and tolerability of the drug in vivo Secondary objective: to evaluate the targeting of GPC3-SPECIFIC imaging agents in patients with hepatocellular carcinoma to assess the feasibility of this targeted agent for future treatment.
