Safety Study of ²¹²Pb-TCMC-Trastuzumab Radio Immunotherapy

Summary

Monoclonal antibodies can transport and deliver radioactive elements capable of releasing sufficient amounts of energy to destroy tumor cells. In this clinical trial, we will study alpha particle radio immunotherapy using lead-212 (²¹²Pb), an isotope with a short path length targeted to malignant cells by the trastuzumab antibody, as a potential treatment for metastatic diseases. This Phase I trial is designed to determine the toxicity profile of ²¹²Pb-TCMC-Trastuzumab, its dose-limiting toxicities, and its anti-tumor effects in patients with HER-2 positive intraperitoneal cancers.
