Abstract
Despite significant advances in recent years, treatment of metastatic malignancies remains a significant challenge. There is an urgent need for development of novel therapeutic approaches. Virotherapy approaches have considerable potential, and among them measles virus (MV) vaccine strains have emerged as a promising oncolytic platform. Retargeted MV strains deriving from the Edmonston vaccine lineage (MV-Edm) have shown comparable antitumor efficacy to unmodified strains against receptor expressing tumor cells with improved therapeutic index. Here, we describe the construction, rescue, amplification, and titration of fully retargeted MV-Edm derivatives displaying tumor specific receptor binding ligands on the viral surface in combination with H protein CD46 and SLAM entry ablating mutations.
