Balancing the efficacy and safety of ixabepilone: Optimizing treatment in metastatic breast cancer

Ixabepilone has been studied in the neoadjuvant setting, as first-line treatment of metastatic disease and in combination with other agents. The efficacy of ixabepilone in triple-negative breast cancer has been the focus of much research. Dose reduction is an effective strategy to manage adverse events associated with ixabepilone and does not result in diminished clinical outcomes. In addition, weekly administration of ixabepilone may decrease toxicity; however, this may come at the expense of lower progression-free survival but not overall survival. The optimal schedule and dosing of this agent will be clarified with the results of upcoming trials.
