Notes to Editors   

Halaven^® (eribulin)   

Eribulin is the first in the halichondrin class of microtubule dynamics inhibitors with a novel mechanism of action. Structurally eribulin is a simplified and synthetically produced version of halichondrin B, a natural product isolated from the marine sponge Halichondria okadai. Eribulin is believed to work by inhibiting the growth phase of microtubule dynamics which prevents cell division.

Eribulin is indicated in the European Union for the treatment of adults with locally advanced or metastatic breast cancer who have received at least one chemotherapeutic regimen for advanced disease in the European Union. Prior therapy should have included an anthracycline and a taxane in either the adjuvant or metastatic setting, unless patients were not suitable for these treatments. Eribulin is also indicated in the European Union for the treatment of adult patients with unresectable liposarcoma who have received prior anthracycline containing therapy (unless unsuitable) for advanced or metastatic disease.

Metastatic Breast Cancer  

On the continent of Africa, more than 92,600 women are diagnosed with breast cancer each year of whom around 30% subsequent develop metastatic disease.^[3],[4] At this advanced stage, the cancer spreads beyond the breast to other parts of the body.

About the EMBRACE (Eisai Metastatic Breast Cancer Study Assessing Treatment of Physician's Choice Versus Eribulin) study^[5]

EMBRACE (Eisai Metastatic Breast Cancer Study Assessing Treatment of Physician's Choice (TPC) Versus Eribulin E7389) was an open-label, randomised, global, multi-centre, parallel two-arm study designed to compare overall survival in women treated with eribulin versus a TPC arm. TPC was defined as any single-agent chemotherapy, hormonal treatment or biologic therapy approved for the treatment of cancer; or palliative treatment or radiotherapy administered according to local practice. The study included 762 participants with MBC who previously had been treated with at least two and a maximum of five prior chemotherapies, including an anthracycline and a taxane. The vast majority (96%) of participants in the TPC arm received chemotherapy.

EMBRACE showed eribulin can prolong median overall survival in people (n=508) with MBC compared to people who received an alternative treatment of physician's choice by 2.7 months (13.2 vs 10.5 HR 0.81 (95% CI 0.67, 0.96) nominal p=0.014). The most commonly reported adverse reactions in the eribulin study arm were fatigue (asthenia), a decrease in infection-fighting white blood cells (neutropenia), hair loss (alopecia), numbness and tingling in arms and legs (peripheral neuropathy), nausea and constipation.
