Eribulin mesylate (eribulin) is a synthetic analogue of the marine-sponge natural product halichondrin B. Eribulin exhibits potent antiproliferative activities against a variety of human cancer cell types in vitro and in vivo, and is used for the treatment of certain patients with advanced breast cancer or liposarcoma who are refractory to other treatments. The antiproliferative effects of eribulin have long been attributed to its anti mitotic activities. Unlike other microtubule-targeting agents, eribulin inhibits microtubule polymerization through specific plus end binding, thus interfering with microtubule dynamic instability. Non-mitotic effects of eribulin on tumor biology have also been established in laboratory settings including: tumor vasculature remodeling, increased vascular perfusion, reduced hypoxia, and phenotypic changes involving reversal of epithelial-to-mesenchymal transition (EMT), resulting in reduced capacities for migration, invasion, and seeding lung metastases in experimental models. Preclinical data suggest that increased perfusion following eribulin treatment improves delivery of subsequent drugs. Supporting evidence for eribulin's non-mitotic effects in the clinical setting include increased tumor oxygen saturation, reduced hypoxia, phenotype changes consistent with EMT reversal, and genotype changes consistent with shifts from nonendocrine-responsive, luminal B, to endocrine-responsive, luminal A, breast cancer subtypes. Finally, potential biomarkers for eribulin response have been established based on tumor-phenotype and gene-expression profiles. Overall, preclinical and clinical data support both antimitotic and non-mitotic mechanisms of eribulin that may underlie the survival benefit observed in various clinical trials.
