Background
Eribulin is used in many countries to treat patients with advanced breast cancer or liposarcoma and exerts in vivo anticancer activity under monotherapy conditions against various human tumor xenograft models. Here, eribulin in combination with mechanistically different anticancer agents was evaluated. Materials and
Conclusion
Eribulin has combination activity with multiple agents from different mechanistic classes in several human cancer models, including breast, NSCLC, ovarian, and melanoma.
Methods
Eribulin was combined with cytotoxic agents (capecitabine, carboplatin, cisplatin, doxorubicin, gemcitabine) or targeted agents (bevacizumab, BKM-120, E7449, erlotinib, everolimus, lenvatinib, palbociclib) in tumor xenograft models of breast cancer, melanoma, non-small cell lung cancer (NSCLC), and ovarian cancer.
Results
Across nearly all models, eribulin with either cytotoxic or targeted agents demonstrated combination activity, defined as the activity demonstrably greater than that of either agent alone. Combination activity was absent only with doxorubicin (MDA-MB-435 model) and with lenvatinib (NCI-H1975 model), both of which responded to the agents as monotherapy.
