European Commission Grants Orphan Drug Status to Eisai's Amatuximab for the
Treatment of Malignant Mesothelioma
HATFIELD, England, January 22, 2014
HATFIELD, England, January 22, 2014 /PRNewswire/ --
The investigational monoclonal antibody amatuximab (development code:
MORAb-009), has today been granted orphan drug designation (ODD) for the
treatment of malignant mesothelioma by the European Commission.
Malignant mesothelioma is a rare form of cancer that affects an estimated 1 in
50,000 (0.2/10,000) people per year in Europe. ^[ ^1] Studies have shown
highest incidence in the UK and Ireland and lowest in Eastern Europe. ^
This aggressive form of lung cancer is caused by asbestos exposure and despite
a dramatic decrease in asbestos use since the mid-70s its incidence is
expected to increase. ^ ^, ^
Amatuximab has high affinity and specificity for mesothelin, a protein which
is overexpressed in people with malignant mesothelioma. Amatuximab was
discovered and developed through Morphotek, a subsidiary wholly owned by
"Eisai is dedicated to providing new options for people with
difficult-to-treat diseases. The ODD for amatuximab highlights the need for
new effective treatments for people with malignant mesothelioma and the
potential for this investigational drug," says Gary Hendler, President & CEO
Eisai EMEA & Russia.
Nick Nicolaides, President and Chief Executive Officer at Morphotek,
commented: "We are extremely pleased that amatuximab has received ODD for the
treatment of malignant pleural mesothelioma in Europe. This reinforces our
commitment to develop safe and effective treatment options for patients
suffering from an extremely invasive but rare disease."
ODD is for medicines developed for the diagnosis, prevention or treatment of
rare diseases that are very serious or life-threatening. In the European Union
(EU), a disease is defined as rare if it affects fewer than five in 10,000
people across the EU. ^
The development of amatuximab underscores Eisai's human health care mission,
the company's commitment to provide innovative solutions in disease
prevention, cure and care for the health and wellbeing of people worldwide.
Eisai is committed to the therapeutic area of oncology and addressing the
unmet medical needs of patients and their families.
Notes to Editors
Amatuximab is a chimeric immunoglobulin G-1-kappa (IgG1/κ) monoclonal antibody
with high affinity and specificity for mesothelin, a glycoprotein currently
considered an important target of mesothelioma treatment, due to its
overexpression on tumour cells. ^
About Malignant Mesothelioma
Mesothelioma is an aggressive and invasive form of lung cancer which
originates from mesothelial cells in the inner lining of the pleural,
peritoneal and pericardial cavities.
The primary cause of malignant mesothelioma is asbestos exposure. Symptoms of
mesothelioma are unspecific and this causes significant delay in diagnosis.
The median survival from the time of diagnosis is 9-12 months. ^
