Cabazitaxel improves survival in patients with metastatic hormone-refractory prostate cancer....

Cabazitaxel (see structure), is an orally bioavailable 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).


Sanofi-aventis recently announced results from a Phase 3 trial which demonstrated cabazitaxel plus prednisone/prednisolone significantly improved overall survival and progression-free survival in patients with metastatic (advanced) hormone-refractory prostate cancer whose disease progressed following treatment with docetaxel-based chemotherapy. 

TROPIC (trial) was designed to assess patients with metastatic hormone-refractory prostate cancer whose disease had progressed following treatment with docetaxel-based chemotherapy. Results showed that the combination of cabazitaxel and prednisone/prednisolone significantly reduced the risk of death by 30%.

Researchers are  happy with these compelling results  and  hope that these results will provide new options and hope for patients with serious diseases, such as metastatic hormone-refractory prostate cancer.....
