Cabazitaxel (previously XRP-6258) is a semi-synthetic derivative of a natural taxoid. It was developed by Sanofi-Aventis and was approved by the U.S. FDA for the treatment of hormone-refractory prostate cancer on June 17, 2010. It is a microtubule inhibitor, and the fourth taxane to be approved as a cancer therapy.

Cabazitaxel in combination is a treatment option for hormone-refractory prostate cancer following docetaxel-based treatment.

Cabazitaxel anticancer mechanism and characteristics similar with docetaxel, belongs to anti-microtubule drugs. Cabazitaxel through binding to tubulin, promoting their assembly into microtubules, and can prevent these have assembled a microtubule disintegration of the stabilization of microtubules, thereby inhibiting cell mitosis, and interphase cellular functions (interphasecellularfunctions) of play.
