-- Submission based on the two largest comparative phase 3 clinical trials of
a novel oral anticoagulant in patients with non-valvular atrial fibrillation
or symptomatic venous thromboembolism

TOKYO and PARSIPPANY, New Jersey, Jan. 8, 2014 /PRNewswire/ -- Daiichi Sankyo
Company, Limited (hereafter, Daiichi Sankyo) today announced that the New Drug
Application (NDA) for its investigational, oral, once-daily direct factor
Xa-inhibitor SAVAYSA™ (edoxaban) Tablets has been submitted to the U.S. Food
and Drug Administration (FDA). In the U.S., Daiichi Sankyo is seeking approval
for edoxaban for the reduction in risk of stroke and systemic embolic events
(SEE) in patients with non-valvular atrial fibrillation (NVAF), as well as for
the treatment of deep vein thrombosis (DVT) or pulmonary embolism (PE) and for
the prevention of recurrence of symptomatic venous thromboembolism (VTE).
SAVAYSA is the proposed brand name for edoxaban if approved for marketing in
the U.S.

The NDA submission is based on data from an extensive global clinical trial
program that compared treatment with once-daily edoxaban to warfarin, a
current standard of care for patients with atrial fibrillation (AF) or VTE.
The two clinical trials that formed the basis of the submission, ENGAGE
AF-TIMI 48 and Hokusai-VTE, are the largest comparative trials of a novel oral
anticoagulant in these patient populations, involving 21,105 and 8,292
patients, respectively.(1),(2)

"The NDA submission in the U.S. is an important milestone in the development
of edoxaban and reflects our long-standing commitment to addressing the needs
of patients living with cardiovascular diseases, including those living with
AF or VTE," said Glenn Gormley, MD, PhD, Senior Executive Officer and Global
Head of Research and Development, Daiichi Sankyo Co., Ltd. and President and
CEO of Daiichi Sankyo, Inc. in the United States. "If approved, edoxaban may
provide a new treatment option for physicians and their patients with these
diseases. We look forward to working with the FDA as it conducts its review of

About Edoxaban Edoxaban is an investigational, oral, once-daily anticoagulant
that specifically inhibits factor Xa, which is an important factor in the
coagulation system that leads to blood clotting.(3) The global edoxaban
clinical trial program includes two phase 3 clinical studies, Hokusai-VTE and
ENGAGE AF-TIMI 48 ( E ffective a N ticoa G ulation with Factor X A Next GE
neration in A trial F ibrillation). The results from these trials form the
basis of the NDA for edoxaban for the prevention of stroke and SEE in patients
with NVAF, as well as for the treatment of DVT or PE and for prevention of
recurrence of symptomatic VTE.

Edoxaban is currently approved only in Japan, since April 2011, for the
prevention of VTE after major orthopaedic surgery, and was launched in July
2011 under the brand name LIXIANA®. Elsewhere, including Europe and the U.S.,
edoxaban is currently in phase 3 clinical development and has not been
approved in any indication.(4)
