105PTargeted delivery of albumin-binding caspase-3 cleavable docetaxel prodrug to radiation exposed local tumor

Background: Targeted delivery of therapeutic agent meets with hurdle of finding target ligand or receptor those are expressed tumor cells in homogenous patterns but not on normal cells. Apoptosis is an event that is programmed in all cells exposed to specific stimuli and this phenotypic event does not vary in patient to patient. In attempt to overcome limitations of conventional targeted therapy, radiation-induced apoptosis-targeted chemotherapy (RIATC) was suggested in our previous study. Caspase-3 cleavable docetaxel prodrug is treated following local administration of low dose radiation in tumor site which induces apoptosis. After initial activation of the prodrug, in-situ amplification of prodrug from expressed caspase-3 boost further activation of the prodrug.
