Mechanism

Ixabepilone binds to a β-tubulin pocket located on the luminal side of microtubules (the taxane site) and can trigger microtubule nucleation at multiple sites away from the centriole. This dysfunctional microtubule stabilization triggers cell-cycle arrest at the G2-M interface and apoptosis.

Indications

Metastatic breast cancer (resistant to or pretreated with anthracyclines and resistant to taxanes)Metastatic breast cancer (monotherapy in patients who have previously progressed through treatment with anthracyclines, taxanes, and capecitabine)

Dosing

Adult
Approximately 40 mg/m2 administered as monotherapy or in combination with capecitabine over 3 h every 3 weeks. Patients should be premedicated with both an H1 and an H2 antagonist before receiving ixabepilone to minimize hypersensitivity reactions.…

Pharmacokinetics

Half-life
52 h (plasma t1/2)
Protein binding
Delivered in cremophor (polyoxyethylated castor oil/ethanol) due to minimal aqueous solubility.
Excretion
Cleared by hepatic CYPs.

Side effects
