What is Cabazitaxel and explain in detail?
Cabazitaxel, sold under the brand name Jevtana, is a semi-synthetic derivative of a natural taxoid. It is a microtubule inhibitor, and the fourth taxane to be approved as a cancer therapy.Cabazitaxel was developed by Sanofi-Aventis and was approved by the U.S. Food and Drug Administration (FDA) for the treatment of hormone-refractory prostate cancer in June 2010. It is available as a generic medication.

Medical uses
Cabazitaxel is indicated in combination with prednisone for the treatment of metastatic castration-resistant prostate cancer following docetaxel-based treatment.

Mechanism of action
Taxanes enhance microtubule stabilization and inhibit cellular mitosis and division. Moreover, taxanes prevent androgen receptor (AR) signaling by binding cellular microtubules and the microtubule-associated motor protein dynein, thus averting AR nuclear translocation.

Clinical trials
In patients with metastatic castration-resistant prostate cancer (mCRPC), overall survival (OS) is markedly enhanced with cabazitaxel versus mitoxantrone after prior docetaxel treatment. FIRSTANA (ClinicalTrials.gov identifier: NCT01308567) assessed whether cabazitaxel 20 mg/m2 (C20) or 25 mg/m2 (C25) is superior to docetaxel 75 mg/m2 (D75) in terms of OS in patients with chemotherapy-naïve mCRPC
