NCIt definition : An enteric-coated formulation of ixabepilone, a semisynthetic analogue of epothilone
B and a non-taxane tubulin inhibitor, with antineoplastic activity. Ixabepilone binds
to and stabilizes tubulin molecules, thereby interfering with the dynamics of microtubule
assembly/disassembly. This results in cell cycle arrest at the G2-M phase and leads
to apoptosis within fast growing tumor cells. This agent demonstrates antineoplastic
activity against taxane-resistant cell lines. Compared to intravenously administered
ixabepilone, the oral formulation provides a more manageable way to administer this
agent.;
