Eribulin is a newer drug (FDA approved for metastatic breast cancer in 2010) that is effective in individuals who have been previously treated with chemotherapy. In a study, known as the EMBRACE trial, women were assigned to receive eribulin or to the treatment chosen by their doctors as predicted to have the best effect. There was a significant survival benefit of about 2.5 months in favor of the eribulin. The drug, derived from sea sponges, works by targeting a scaffolding protein (microtubule) within a cell and interferes with the construction of the scaffolding and stops the cancer cell from dividing.
