Company Plans Fourth-Quarter Launch for XIENCE V in China - The
Second-Largest Drug Eluting Stent Market in the Asia-Pacific Region
ABBOTT PARK, Ill., Sept. 14 /PRNewswire-FirstCall/ -- Abbott
(NYSE:ABT) announced today that the Chinese State Food and Drug
Administration (SFDA) has approved its XIENCE V Everolimus Eluting
Coronary Stent System for the treatment of coronary artery disease
(CAD) - the leading cause of death in China. XIENCE V is the only
drug eluting stent to have demonstrated superiority over the TAXUS
Paclitaxel-Eluting Coronary Stent System (TAXUS) in the primary
endpoints of two randomized, pivotal (phase III) clinical trials.
The company plans a fourth-quarter launch for XIENCE V in China,
which is the second-largest drug eluting stent market in the
Asia-Pacific region after Japan. With approval in China, XIENCE V
is now available in every Asia-Pacific market except Japan, where
approval is anticipated at the end of this year. "Since it first
became commercially available in 2006, XIENCE V has become the
market-leading drug eluting stent around the world due to its
excellent outcomes and outstanding deliverability," said Robert
Hance, senior vice president, vascular, Abbott. "As the incidence
of heart disease and the number of annual stent procedures continue
to increase in China, it is critical for physicians and patients to
have access to one of the most advanced drug eluting stent
technologies. We look forward to making XIENCE V available in
China." According to the China Chronic Heart Disease 2006 Annual
Report, nearly 50 percent of all deaths annually in China are due
to CAD, and the prevalence of coronary artery disease has steadily
increased each year. Approximately 150,000 patients annually
undergo a stent procedure for the treatment of CAD, and the number
of procedures is growing by more than 20 percent each year in
China. "Heart disease is a serious health issue in China, with more
patients being diagnosed each day, so it is critical to have access
to advanced technology, such as XIENCE V, that can help improve
patient outcomes," said Run Lin Gao, M.D., vice president, Chinese
Medical Doctor Association. "Clinical trial results show that
XIENCE V has a strong safety and efficacy profile, with
impressively low rates of major adverse cardiac events and target
vessel failure. Based on the strength of the data supporting it,
XIENCE V is a welcome addition to the heart disease treatment
options available to physicians in China," said Yong Huo, M.D.,
president-elect, Chinese Society of Cardiology. SPIRIT Body of Data
for XIENCE V The clinical program for XIENCE V includes outstanding
long-term results from the SPIRIT family of trials, including data
from more than 60 patients based in China. In October 2008 at the
Transcatheter Cardiovascular Therapeutics annual meeting, Abbott
presented two-year results from a meta-analysis of the SPIRIT II
and SPIRIT III* randomized clinical trials, which included 1,302
patients from the United States, Europe and the Asia-Pacific
region. In this meta-analysis, XIENCE V demonstrated a 45 percent
reduction in the risk of major adverse cardiac events (MACE)
compared to TAXUS at two years (7.1 percent for XIENCE V vs. 12.3
percent for TAXUS, p-value=0.001)** . MACE is an important
composite clinical measure of safety and efficacy outcomes for
patients, defined as cardiac death, heart attack (myocardial
infarction or MI), or ischemia-driven target lesion
revascularization (ID-TLR driven by lack of blood supply). XIENCE V
also demonstrated significantly lower clinical events rates than
TAXUS in the key efficacy (ID-TLR) and safety (cardiac death or
heart attack) components of MACE at two years in the SPIRIT II and
SPIRIT III meta-analysis. XIENCE V demonstrated a 41 percent
reduction in the risk of ID-TLR compared to TAXUS (4.1 percent for
XIENCE V vs. 6.8 percent for TAXUS, p-value=0.03)**, and a 41
percent reduction in the risk of cardiac death or heart attack (MI)
compared to TAXUS (3.8 percent for XIENCE V vs. 6.3 percent for
TAXUS, p-value=0.04)**. In March 2009 at the American College of
Cardiology annual meeting, Abbott presented long-term data from the
SPIRIT II clinical trial of 300 patients, which showed that
patients treated with XIENCE V continue to experience fewer heart
attacks, deaths or repeat procedures at the target lesion compared
to patients treated with TAXUS out to three years. XIENCE V
demonstrated a 57 percent reduction in the risk of MACE compared to
TAXUS at three years (6.4 percent for XIENCE V vs. 14.9 percent for
TAXUS, p-value=0.029)**. In addition, there was no occurrence of
stent thrombosis between two and three years with XIENCE V, and a
low rate of stent thrombosis from zero to three years, per Academic
Research Consortium (ARC) definition of definite/probable stent
thrombosis (0.9 percent for XIENCE V and 2.8 percent for TAXUS,
p-value=0.27)** in the SPIRIT II trial. The ARC definitions of
stent thrombosis were developed to eliminate variability in the
definitions across various drug eluting stent trials. In May 2009
at EuroPCR, Abbott presented one-year data from the SPIRIT V (five)
international, single-arm study, which evaluated XIENCE V in 2,663
patients - including more than 60 patients enrolled at two sites in
China. XIENCE V demonstrated low rates of repeat procedure (target
lesion revascularization or TLR), stent thrombosis and MACE in a
diverse, "real world" population of patients and lesion types,
including patients with diabetes, patients with multi-vessel
disease and patients with highly complex lesions. In the SPIRIT V
study, XIENCE V demonstrated a very low 1.8 percent rate of TLR, a
0.7 percent rate of definite/probable stent thrombosis and a 5.1
percent rate of MACE at one year. For the SPIRIT V trial, MACE is
defined as a composite of cardiac death, heart attack (myocardial
infarction not clearly attributed to a non-target vessel), or TLR.
In September 2009, data from the company's SPIRIT IV trial
comparing XIENCE V to TAXUS will be presented at the Transcatheter
Cardiovascular Therapeutics annual meeting. With 3,690 patients,
the SPIRIT IV trial is one of the largest head-to-head randomized
clinical trials between two drug eluting stents and includes more
than 1,000 patients with diabetes. More About XIENCE V XIENCE V is
used to treat coronary artery disease by propping open a narrowed
or blocked artery and releasing the drug, everolimus, in a
controlled manner to prevent the artery from becoming blocked again
following a stent procedure. XIENCE V is built upon Abbott's
market-leading bare metal stent, the MULTI-LINK VISION Coronary
Stent System. The VISION platform is designed to facilitate ease of
delivery, making it easier for physicians to maneuver the stent and
treat the diseased portion of the artery. The XIENCE V drug coated
stent will be available in China on the rapid exchange (RX)
delivery system. Rapid exchange is the most widely used type of
delivery system because it provides physicians additional
flexibility to work as single operators during stent procedures.
Abbott's market-leading XIENCE V drug eluting stent is marketed in
the United States, Europe and other international markets. XIENCE V
is an investigational device in Japan and is currently under review
by Japan's Ministry of Health, Labour and Welfare and the
Pharmaceuticals and Medical Devices Agency. Everolimus, developed
by Novartis Pharma AG, is a proliferation signal inhibitor, or mTOR
inhibitor, licensed to Abbott by Novartis for use on its drug
eluting stents. Everolimus has been shown to inhibit in-stent
neointimal growth in the coronary vessels following stent
implantation, due to its antiproliferative properties. XIENCE V is
indicated for improving coronary luminal diameter in patients with
symptomatic heart disease due to de novo native coronary artery
lesions (lesions less than or equal to 28 mm) with reference vessel
diameters of 2.5 mm to 4.25 mm. Additional information about XIENCE
V, including important safety information, is available online at
