HATFIELD, England, September 4, 2013 /PRNewswire/ --

 Reimbursement granted for Halaven ^®  (eribulin) for patients with locally
                     advanced or metastatic breast cancer

Halaven ^® (eribulin), has today received reimbursement approval from The
Spanish Directorate General of Pharmacy and Health Products, belonging to the
Spanish Ministry of Health as a novel treatment for 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 two common types of chemotherapy, an anthracycline and a taxane,
unless patients were not suitable for these treatments. ^[1] Eribulin is the
first, single-agent chemotherapy to demonstrate a prolonged overall survival
in patients with heavily pre-treated advanced breast cancer. ^[2]

In Spain, breast cancer is now the second most common cause of female cancer
death ^[ ^3] and approximately 22,000 cases of breast cancer are diagnosed
annually. ^[3] Spain has one of the lowest breast cancer mortality ^[4] and
incidence ^[5] rates in Europe which is attributable to Spain's significant
investment in breast cancer screening programmes. ^[6] In addition, the
Spanish Cancer Strategy's goal is to promote an integrated multidisciplinary
approach to cancer care, with prompt access to diagnosis and therapy. ^[7] The
reimbursement of eribulin illustrates Spain's commitment to its strategy. 

"As a scientific non profit foundation that supports patients living with
metastatic breast cancer, we believe that the approval of eribulin is a step
towards a new treatment option for these patients," commented Dr Ana Lluch,
member of the Board of GEICAM (Spanish Breast Cancer Research Group).

"Eribulin addresses an urgent need for new treatment options for women in
Spain with advanced breast cancer who have previously received multiple
treatments," commented Dr Javier Cortes, Head of the Breast Cancer Programme,
Vall d'Hebron Institute of Oncology and University Hospital, Barcelona, Spain.
"Now that Halaven is approved for reimbursement in Spain it provides an
important addition to the present therapy armamentarium for patients with
advanced breast cancer. Women in Spain can now benefit from a treatment that
has a proven overall survival benefit." 

Principal Investigator Dr Javier Cortes was involved in the study design, data
analysis and interpretation of the pivotal Phase III EMBRACE clinical trial
for eribulin. Spain recruited the largest number of patients from any one
country to the trial and over 50 patients were recruited by the Vall d'Hebron
University Hospital alone. This contributed to valuable physician and patient
experience data that led to the EMA marketing approval of eribulin in March
2011.

"We are very proud that eribulin is now accessible to women with metastatic
breast cancer in Spain. We have worked very hard to ensure that the cost of
eribulin remains economically viable, especially in this tough economic
climate. Eribulin will play a valuable role in improving metastatic breast
cancer treatment options for women in Spain," commented Miguel Marcão Managing
Director for Spain, Eisai Europe Ltd. "Eisai is working closely with regional
health authorities to ensure life-extending eribulin reaches the patients that
need it, as soon as possible."

In the Phase III EMBRACE (Eisai Metastatic Breast Cancer Study Assessing
Treatment of Physician's Choice (TPC) Versus Eribulin E7389) study population
(n=762), eribulin was shown to prolong overall survival in heavily pre-treated
patients with metastatic breast cancer by 2.5 months compared to patients
receiving Treatment of Physicians Choice (TPC), representing a mix of
real-life treatment choices (eribulin 13.1 months vs. TPC 10.6 months, HR 0.81
(95% CI 0.66, 0.99) p=0.041). ^[ ^1] ^, ^[ ^2] Updated data from the pivotal
Phase III EMBRACE trial confirmed these results, showing that patients treated
with eribulin survived a median of 2.7 months longer than patients who
received treatment of physician's choice (overall survival of 13.2 months
versus 10.5 months, respectively, HR 0.81 (95% CI 0.067, 0.96), nominal
p=0.014). ^[ ^1] ^, ^[ ^2] A pre-planned analysis of patients from Region 1 of
the study (North America/Western Europe/Australia) showed a significant
overall survival benefit of eribulin over TPC of 3.0 months (p=0.009). ^[ ^2]

The most commonly reported adverse reactions among patients treated with
eribulin were asthenia (fatigue), neutropenia, alopecia (hair loss),
peripheral neuropathy (numbness and tingling in arms and legs), nausea and
constipation. ^[ ^2]

Eribulin received European Commission approval on 17 March 2011 based on the
results of the Phase III EMBRACE study. Eribulin is approved in 50 countries
across the world including the European Union, USA, Russia, Switzerland, South
Korea Japan, and Singapore. Halaven has received pricing authorisation and has
launched in Canada, Denmark, Finland, France, Iceland, Italy, Norway, Sweden,
Switzerland, Slovenia, and the UK. In addition, Halaven is available in
Austria and Germany.

Eisai is dedicated to discovering, developing and producing innovative
oncology therapies that can make a difference and impact the lives of women
and their families. This passion for people is part of Eisai's human health
care (hhc) mission, which strives for better understanding of the needs of
patients and their families to increase the benefits health care provides.

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. ^[1 ^] Eribulin belongs to
a class of antineoplastic agents, the halichondrins, which are natural
products, isolated from the marine sponge Halichondria okadai. ^[ ^8] 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.

Global Phase III Clinical Study 305 (EMBRACE) ^[2]

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 patients treated with eribulin versus a Treatment of Physician's
Choice (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 patients with metastatic breast cancer 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 patients
in the TPC arm received chemotherapy.

The most commonly reported adverse reactions among patients treated with
eribulin in the EMBRACE study were fatigue (asthenia), a decrease in
infection-fighting white blood cells (neutropaenia), hair loss (alopecia),
numbness and tingling in arms and legs (peripheral neuropathy), nausea and
constipation. Peripheral neuropathy was the most common adverse event leading
to discontinuation from eribulin, occurring in less than 5% of the patients
involved in the EMBRACE trial. Neutropaenia only led to eribulin
discontinuation for 0.6% patients. Death due to serious side effects,
discontinuation and dose interruptions to treatment were lower in the eribulin
arm of the trial compared with the TPC arm.

Metastatic Breast Cancer

Over 300,000 women are diagnosed with breast cancer in Europe every year, of
whom about one third subsequently develop metastatic disease. ^[9] ^, ^[10]
Metastatic disease is an advanced stage of the disease that occurs when cancer
spreads beyond the breast to other parts of the body.
