Schematic of MM-302, a novel HER2-targeted antibody–liposomal doxorubicin conjugate. MM-302 consists of doxorubicin encapsulated by a liposome that is conjugated to an anti-HER2 scFv antibody via a polyethylene glycol spacer (PEG-DSPE). MM-302 thus directly targets PEGylated liposomal doxorubicin to HER2-overexpressing tumor cells
