Fig. 2From: HERMIONE: a randomized Phase 2 trial of MM-302 plus trastuzumab versus chemotherapy of physician’s choice plus trastuzumab in patients with previously treated, anthracycline-naïve, HER2-positive, locally advanced/metastatic breast cancerSchematic 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 cellsBack to article page
