Eribulin effective in metastatic breast cancer, researchers find

“Additionally, it is of great interest that subset analysis suggests that eribulin may be particularly active and effective in triple negative MBC, which is known to be an aggressive subset of breast cancer, and one associated unfortunately with a particularly poor prognosis overall,” said Kaufman.

“Additionally, it is of great interest that subset analysis suggests that eribulin may be particularly active and effective in triple negative MBC, which is known to be an aggressive subset of breast cancer, and one associated unfortunately with a particularly poor prognosis overall,” said Kaufman.

Eribulin has been approved in numerous countries in the third line or latter setting for the treatment of MBC, and is increasingly widely used. It is the only chemotherapeutic agent shown to have a survival benefit for patients with MBC in the third line or latter chemotherapeutic setting. Given previous research findings, and now findings from this large international trial, there has been great interest from oncologists and other clinicians in the potential impact that eribulin might have earlier in the course of MBC.

This phase III randomized trial assigned 1,099 women who had previously been treated with an anthracycline or a taxane to either eribulin or capecitabine as their first, second, or third line chemotherapy for advanced MBC. Stratification factors were human epidermal growth factor receptor-2 (HER2) status and geographic region. Coprimary endpoints were overall survival and progression-free survival.

“While there is not a statistically significant difference in overall survival with eribulin in comparison to capecitabine, the median overall survival seen with eribulin is in fact numerically slightly superior to that of capecitabine,” explained Kaufman.

This work supports, and has in part led to, a number of further studies of eribulin in breast cancer. Plans are underway to proceed with pilot adjuvant and neoadjuvant studies, and further studies in MBC. “We are currently developing further studies evaluating the utility of eribulin in treating women with triple negative disease, either alone, or in combination regimens with other therapies,” Kaufman commented. “We are additionally planning further research evaluating the role of eribulin in other subtypes of breast cancer, particularly in early stage breast cancer, where this therapy may in fact have a great impact, and improve the cure rate for early stage disease.”
