Eribulin for locally advanced or metastatic breast cancer third line; monotherapy Target group Breast cancer: locally advanced or metastatic third line; monotherapy. Technology description Eribulin (E7389; ER086526; Eribulin mesylate) is a synthetic analogue of halichondrin. B. Halichondrins have been isolated from a variety of marine sponges, including Halichondria okadai, Axinella sp., Phakellia carteri, and Lissodendoryx sp., and exhibit antitumour activity through the inhibition of tubulin polymerisation. The destabilisation of tubulin polymers disrupts the assembly and formation of microtubules, which in turn arrests cancer cell division. Eribulin is administered at 1.4mg/m 2 intravenously (IV) on days 1 and 8 of a 21 day cycle. Eribulin is in phase II clinical trials for non-small cell lung cancer, prostate cancer and soft tissue sarcoma. Innovation and/or advantages Eribulin is a new class of drug with a novel mechanism of action, which could improve patient outcomes. Developer Eisai Ltd.

Clinical need and burden of disease Breast cancer is the most common malignancy affecting women in the UK. There were 40,849 women newly diagnosed with breast cancer in England and Wales during 2005 12 and in 2006 there were 10,984 registered deaths 13. Between 16-20% of women (an estimated 6,536 to 8,170) presenting with breast cancer have advanced disease with distant metastases and in 2002 NICE estimated that around 50% of those presenting with early or localised breast cancer will eventually develop metastatic breast cancer 14. Existing comparators and treatments For patients with metastatic disease the aim of treatment is to ameliorate symptoms, maintain quality of life and prolong survival. Chemotherapeutic resistance in women with prior exposure to anthracyclines and taxanes is a major therapeutic challenge. Current treatment options include: First line chemotherapy: usually an anthracycline based regimen or a combination of cyclophosphamide, methotrexate and fluorouracil. Following disease progression on an anthracycline, other chemotherapy options include single-agent or combination taxanes, capecitabine, vinorelbine, lapatinib and gemcitabine.

Estimated cost and cost impact The cost of eribulin is not yet known. Potential or intended impact speculative Patients Reduced morbidity Quicker, earlier or more accurate diagnosis or identification of disease Reduced mortality or increased length of survival Other: Improved quality of life for patients and/or carers None identified Services Increased use Service reorganisation required Staff or training required Decreased use Costs Increased unit cost compared to alternative New costs: additional treatment option. Other: if used instead of oral agent, associated IV costs Increased costs: more patients coming for treatment Savings: None identified Increased costs: capital investment needed Other: 4
