Description

Cabazitaxel is an anti-neoplastic used with the steroid medicine prednisone. Cabazitaxel is used to treat people with prostate cancer that has progressed despite treatment with docetaxel. Cabazitaxel is prepared by semi-synthesis with a precursor extracted from yew needles (10-deacetylbaccatin III). It was approved by the U.S. Food and Drug Administration (FDA) on June 17, 2010.

Pharmacodynamics

Cabaitaxel has anti-tumour properties and is effective against docetaxel-sensitive and -insensitive tumours.

Mechanism of action

Cabazitaxel is a microtubule inhibitor. Cabazitaxel binds to tubulin and promotes its assembly into microtubules while simultaneously inhibiting disassembly. This leads to the stabilization of microtubules, which results in the interference of mitotic and interphase cellular functions. The cell is then unable to progress further into the cell cycle, being stalled at metaphase, thus triggering apoptosis of the cancer cell.

Absorption

After an intravenous dose of cabazitaxel 25 mg/m2 every three weeks to a population of 170 patients with solid tumors, the mean Cmax in patients with metastatic prostate cancer was 226 ng/mL (CV 107%) and was reached at the end of the one-hour infusion (Tmax). The mean AUC in patients with metastatic prostate cancer was 991 ng.h/mL (CV 34%). Administration with prednisone or prednisolone do not effect the pharmacokinetic profile of cabazitaxel.

Volume of distribution

The volume of distribution (Vss) was 4,864 L (2,643 L/m2 for a patient with a median BSA of 1.84 m2) at steady state. Compared to other taxanes, penetrates the CNS to a greater extent.

Protein binding

Cabazitaxel is mainly bound to human serum albumin (82%) and lipoproteins (88% for HDL, 70% for LDL, and 56% for VLDL).

Metabolism

Cabazitaxel is extensively metabolized in the liver (>95%), mainly by the CYP3A4/5 isoenzyme (80% to 90%), and to a lesser extent by CYP2C8 which results in 20 different metabolites. Two of these metabolites are active demethylated derivatives of cabaxitaxel and referred to as RPR112698 and RPR123142 respectively. Docetaxel is another metabolite of cabazitaxel. Cabazitaxel is the main circulating moiety in human plasma.

Route of elimination

After a one-hour intravenous infusion [14C]-cabazitaxel 25 mg/m2, approximately 80% of the administered dose was eliminated within 2 weeks. Cabazitaxel is mainly excreted in the feces as numerous metabolites (76% of the dose); while renal excretion of cabazitaxel and metabolites account for 3.7% of the dose (2.3% as unchanged drug in urine).

Half-life

Following a one-hour intravenous infusion, plasma concentrations of cabazitaxel can be described by a three-compartment pharmacokinetic model with α-, β-, and γ- half-lives of 4 minutes, 2 hours, and 95 hours, respectively.

Clearance

Cabazitaxel has a plasma clearance of 48.5 L/h (CV 39%; 26.4 L/h/m2 for a patient with a median BSA of 1.84 m2) in patients with metastatic prostate cancer.

Toxicity

Cabazitaxel may cause serious side effects including neutropenia, hypersensitivity reactions, gastrointestinal symptoms, and renal failure. Anticipated complications of overdose include exacerbation of adverse reactions such as bone marrow suppression and gastrointestinal disorders. Cabazitaxel penetrates the blood-brain barrier.

Chemical TaxonomyProvided by Classyfire
Description
This compound belongs to the class of organic compounds known as taxanes and derivatives. These are diterpenoids with a structure based either on the taxane skeleton, or a derivative thereof. In term of phytochemistry, several derivatives of the taxane skeleton exist: 2(3->20)-abeotaxane, 3,11-cyclotaxane, 11(15->1),11(10->9)-abeotaxane, 3,8-seco-taxane, and 11(15->1)-abeotaxane, among others. More complex skeletons have been found recently, which include the taxane-derived [3.3.3] propellane ring system.
