NCIt definition : A lipid microsphere (LM)-based formulation containing the poorly water soluble taxane
docetaxel, a semi-synthetic analogue of paclitaxel, with antineoplastic activity.
Docetaxel binds specifically to the beta-tubulin subunit of the microtubule, stabilizing
tubulin and inhibiting microtubule disassembly, which causes cell cycle arrest at
the G2/M phase and leads to cell death. This agent also inhibits pro-angiogenic factors
such as vascular endothelial growth factor (VEGF) and induces various mediators of
the inflammatory response. Compared to docetaxel alone, the LM formulation may enhance
stability, improve efficacy and may reduce toxicity; this formulation does not contain
toxic detergents needed to solubilize docetaxel which further improves its side effect
profile.;
