-The Sixth Designation for Chugai Originated Drug-

TOKYO–(BUSINESS WIRE)–#biotechChugai
Pharmaceutical Co., Ltd.
(TOKYO:4519) announced today that the U.S.
Food and Drug Administration (FDA) has granted Breakthrough Therapy
Designation for its anti-coagulation factor IXa/X humanized bispecific
monoclonal antibody / coagulation factor VIII substitute, “HEMLIBRA®
[US generic name: emicizumab-kxwh] for people with hemophilia A without
factor VIII inhibitors. Development and distribution of the drug in the
US is conducted by Genentech,
a member of Roche Group.

“We are thrilled that HEMLIBRA has been granted its second Breakthrough
Therapy Designation,” said Chugai’s Executive Vice President, Co-Head of
Project & Lifecycle Management Unit, Dr. Yasushi Ito. “This will allow
us to expedite potential delivery of this new therapy we created to
people with hemophilia A without inhibitors in the US following the
previous designation for inhibitors. We continue to work closely with
Genentech to enable this line extension as soon as possible.”

This designation is based on the global phase III HAVEN 3 (NCT02847637)
study evaluating HEMLIBRA subcutaneous injection once a week and once
every two weeks in people with hemophilia A (12 years of age or older)
without inhibitors to factor VIII.

Hemophilia A is a disease presenting repeated severe bleeding symptoms.
In this disease, the blood coagulation reaction does not proceed
normally due to the deficiency or functional disorder of coagulation
factor VIII. For people with hemophilia A without inhibitors, regular
factor VIII replacement therapy has been widely used to prevent
bleeding. HEMLIBRA is a bispecific monoclonal antibody, which was
developed using Chugai’s proprietary antibody engineering technologies.
The drug is designed to bind factor IXa and factor X. In doing so,
HEMLIBRA provides the cofactor function of factor VIII in people with
hemophilia A, who either lack or have impaired coagulation function of
factor VIII1, 2). In the HAVEN 3 study, a statistically
significant reduction in the frequency of bleeding episodes was observed
with HEMLIBRA. With the convenience of subcutaneous administration and
the lower frequency of administration, it is expected to be a new
treatment option for hemophilia A.

This is the sixth Breakthrough Therapy Designation received for three
drugs created by Chugai: ALECENSA® (ALK-positive non-small
cell lung cancer with disease progression on crizotinib, and first line
treatment for ALK-positive non-small cell lung cancer), ACTEMRA®
(systemic sclerosis and giant cell arteritis), and HEMLIBRA
(prophylactic treatment for patients 12 years or older with hemophilia A
with factor VIII inhibitors).

enacted in July 2012 aiming at expediting the development and review of
drugs for the treatment of severe or life-threatening diseases or
symptoms. In order to grant Breakthrough Therapy Designation,
preliminary clinical evidence is required demonstrating that the drug
may have substantial improvement on at least one clinically significant
endpoint over existing therapies. Breakthrough Therapy Designation
includes the features of a Fast Track designation, with the addition of
intensive guidance on efficient drug development as well organizational
commitment from FDA.
