Cabazitaxel (previously XRP-6258, trade name Jevtana) is a semi-synthetic derivative of a natural taxoid.[1] 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.[2][unreliable source?]

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

Mechanism of action[edit]

Taxanes enhance the microtubules stabilization and inhibit the cellular mitosis and division.[3] Moreover, taxanes prevent androgen receptor (AR) signaling by binding cellular microtubules and the microtubule-associated motor protein dynein, thus averting AR nuclear translocation.[4]

Clinical trials[edit]

In patients with metastatic castration-resistant prostate cancer (mCRPC), overall survival (OS) is markedly enhanced with cabazitaxel versus mitoxantrone after prior docetaxel treatment. FIRSTANA ( 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. However, C20 and C25 did not demonstrate superiority for OS versus D75 in patients with chemotherapy-naïve mCRPC. Cabazitaxel and docetaxel demonstrated different toxicity profiles, and C20 showed the overall lowest toxicity.[5] In a phase III trial with 755 men for the treatment of castration-resistant prostate cancer, median survival was 15.1 months for patients receiving cabazitaxel versus 12.7 months for patients receiving mitoxantrone. Cabazitaxel was associated with more grade 3–4 neutropenia (81.7%) than mitoxantrone (58%).[6] Common adverse effects with cabazitaxel include neutropenia (including febrile neutropenia) and GIT side effects appeared mainly in diarrhea, whereas, neuropathy was rarely detected.[7]


Cabazitaxel administration causes a decrease in plasma concentrations showing triphasic kinetics: a mean half life (t1/2) of 2.6 min in the first phase, a mean t1/2 of 1.3 h in the second phase, and a mean t1/2 of 77.3 h in the third phase.[8]


Cabazitaxel is basically metabolized in the liver by [cytochrome P450 (CYP)3A4/5 > CYP2C8], which result in seven plasma metabolites and excreted 20 metabolites. During 14 days after administration, 80% of cabazitaxel is excreted: 76% in the feces and 3.7% as a renal excretion.[9]

Dosing of Cabazitaxel[edit]

There are many questions about the optimal use of Cabazitaxel after the approval of using it in the treatment of docetaxel-refractory mCRPC. One question is about the optimal use. Concerning the significant myelosuppression during cabazitaxel administration at 25 mg/m2, a randomized phase III study will appraise the safety and efficacy of cabazitaxel at 20 mg/m2.  One more question is about the effectiveness and tolerability of cabazitaxel when it is administered with other therapies. A phase I/II trials are testing the co-administration of cabazitaxel with other therapies (e.g. abiraterone) and investigational agents (e.g. custirsen)[9]
