The information discussed in this release is about investigational uses for
eribulin. In Europe, eribulin is indicated for the treatment of patients with
locally advanced or metastatic breast cancer who have progressed after at
least two chemotherapeutic regimens for advanced disease. Prior therapy should
have included an anthracycline and a taxane unless patients were not suitable
for these treatments. ^[1] It is not intended to convey conclusions of
efficacy and safety.

Notes to Editors

Halaven ^®  (eribulin)

Eribulin is a non-taxane, microtubule dynamics inhibitor indicated for the
treatment of patients with breast cancer who have previously received at least
two chemotherapeutic regimens for metastatic disease and whose prior therapy
should have included an anthracycline and a taxane. Eribulin belongs to a
class of antineoplastic agents, the halichondrins, which are natural products,
isolated from the marine sponge Halichondria okadai. It is believed to work by
inhibiting the growth phase of microtubule dynamics without affecting the
shortening phase and sequesters tubulin into non-productive aggregates.

Halaven is approved in the European Union, USA, Switzerland, Japan, and
Singapore. Halaven has received pricing authorisation and been launched in
Austria, Canada, Denmark, Finland, Germany, Iceland, Italy, Norway, Russia,
South Korea, Sweden, Switzerland, Slovenia, and the UK.

Metastatic Breast Cancer

Metastatic breast cancer is an advanced stage of the disease that occurs when
cancer spreads beyond the breast to other parts of the body. In Europe,
approximately 6% of breast cancers are metastatic at diagnosis with a
five-year survival rate of 21%. ^[2]
