US Brand Name: Jevtana

A semi-synthetic derivative of the natural taxoid 10-deacetylbaccatin III with potential antineoplastic activity. Cabazitaxel binds to and stabilizes tubulin, resulting in the inhibition of microtubule depolymerization and cell division, cell cycle arrest in the G2/M phase, and the inhibition of tumor cell proliferation. Unlike other taxane compounds, this agent is a poor substrate for the membrane-associated, multidrug resistance (MDR), P-glycoprotein (P-gp) efflux pump and may be useful for treating multidrug-resistant tumors. In addition, cabazitaxel penetrates the blood-brain barrier (BBB).

Why is this medication prescribed?

Cabazitaxel injection is used along with prednisone to treat prostate cancer (cancer of a male reproductive organ) that has already been treated with other medications. Cabazitaxel injection is in a class of medications called microtubule inhibitors. It works by slowing or stopping the growth of cancer cells.
