Ixemprya Uses, Dosage, Side Effects, Food Interaction and all others data.

Ixemprya is an epothilone B analog developed by Bristol-Myers Squibb as a cancer drug. It was FDA approved on October 16, 2007, for the treatment of unresponsive aggressive metastatic or locally advanced breast cancer. Ixemprya is administered through injection, and will be marketed under the trade name Ixempra. Ixemprya is a semisynthetic analogue of epothilone B. It has a lactone–lactam modification that minimizes susceptibility to esterase degradation.

Uses

Ixemprya is a microtubule inhibitor administered in combination with capecitabine or alone in the treatment of metastatic or locally advanced breast cancer that has shown inadequate response to taxanes and anthracyclines.

Investigated for use/treatment in breast cancer, head and neck cancer, melanoma, lung cancer, lymphoma (non-hodgkin's), prostate cancer, renal cell carcinoma, and cancer/tumors (unspecified).

Ixemprya is also used to associated treatment for these conditions: Locally Advanced Breast Cancer (LABC), Metastatic Breast Cancer

How Ixemprya works

Binding of Ixemprya to beta-tubulins (e.g. beta-III tubulin) stabilizes microtubules. Microtubules are essential to cell division, and epothilones therefore stop cells from properly dividing. Like taxol, Ixemprya binds to the αβ-tubulin heterodimer subunit. Once bound, the rate of αβ-tubulin dissociation decreases, thus stabilizing the microtubules.

Food Interaction

  • Avoid grapefruit products. Grapefruit inhibits the CYP3A4 metabolism of ixabepilone, which may increase its serum concentration.
  • Avoid St. John's Wort. This herb induces CYP3A metabolism and may reduce serum levels of ixabepilone.

[Moderate] GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of ixabepilone.

The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits.

MANAGEMENT: Patients treated with ixabepilone should avoid the consumption of grapefruit or grapefruit juice.
