| Outline of Final Research Achievements |
Molecular targeted therapies, such as monoclonal antibodies, were widely used for various cancers recently, leading to improve patients’ outcomes. Photoimmunotherapy (PIT) is a new class of molecular targeted cancer theranostics, which employs monoclonal antibody conjugated to a photosensitizer, IR700, that is activated by focal near-infrared (NIR) light irradiation leading to necrotic cell death. In this study, we developed a new type of PIT agents targeting VEGFR-2 expressed on vascular endothelium in a tumor stroma and Trop2 expressed on various types of cancer cell. We also developed photoactivatable functionalized liposome that can be used for PIT. Further study is needed for clinical translation,
