XIENCE V USA Study to Evaluate Treatment of Coronary Artery Disease
Patients in Real-World Setting ABBOTT PARK, Ill., July 9
/PRNewswire-FirstCall/ -- Abbott today announced the start of the
XIENCE V(TM) USA post-approval study, with six hospital centers
already recruiting and enrolling patients just one week after the
U.S. Food and Drug Administration approved the XIENCE V(TM)
Everolimus Eluting Coronary Stent System. The XIENCE V USA study
will evaluate the safety and effectiveness of the XIENCE V drug
eluting stent in a real-world clinical setting out to five years.
Jack Jones, M.D., interventional cardiologist and medical director
of the Stormont-Vail Catheterization Lab in Topeka, Kan., was one
of the first physicians to enroll a patient into the study. "XIENCE
V is an important innovation that gives patients in the United
States access to a next-generation drug eluting stent that has been
shown in clinical trials to improve patient outcomes," said Dr.
Jones. "During the stent procedure, we found it easy to deliver
XIENCE V to the diseased portion of the vessel. With its
combination of clinical efficacy and deliverability, I believe that
XIENCE V will become a key advancement in the treatment of coronary
artery disease." The XIENCE V USA study is designed to evaluate at
least 5,000 coronary artery disease patients treated with the
XIENCE V drug eluting stent at approximately 250 centers across the
United States. The primary endpoint of XIENCE V USA is a measure of
stent thrombosis (formation of blood clots) every year out to five
years, as defined by the Dublin/Academic Research Consortium (ARC).
The ARC definition of late stent thrombosis was developed to
eliminate variability in the definitions across various drug
eluting stent trials. The co-primary endpoint of the study is the
composite rate of cardiac death and any heart attack (Q-wave or
non-Q-wave myocardial infarction) in patients at one year.
Secondary endpoints of the study include patient compliance with
prescribed anti-platelet medication, measures of re-treatment by
stenting or surgery, and device and procedural success.
"Post-approval studies allow physicians to follow the safety and
efficacy of new treatments in a more complex patient population
than is typically studied in pre-approval clinical trials. XIENCE V
USA will provide significant insight about the performance of
Abbott's new drug eluting stent in a variety of patients," said
Charles Simonton, M.D., FACC, FSCAI, divisional vice president,
Medical Affairs and chief medical officer, Abbott Vascular. "Our
ability to work with our physician partners to begin this
post-approval study within days of FDA approval is further evidence
of Abbott's commitment to help the interventional cardiology
community gain additional insights about the clinical benefits of
XIENCE V." 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(R) 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. Long-term results with XIENCE V in the SPIRIT III
pivotal U.S. clinical trial demonstrated a 45 percent reduction in
the risk of major adverse cardiac events (MACE) compared to the
TAXUS(R) paclitaxel-eluting coronary stent system at two years.
XIENCE V demonstrated a 32 percent reduction in target vessel
failure (TVF, cardiac events related to the stented vessel)
compared to TAXUS at two years. XIENCE V also demonstrated a low
rate of stent thrombosis between one and two years, defined as very
late stent thrombosis, per Academic Research Consortium (ARC)
definition of definite/probable stent thrombosis (0.3 percent for
XIENCE V and 1.0 percent for TAXUS). XIENCE V met its primary
endpoint in the SPIRIT III clinical trial with a statistically
significant 50 percent reduction in in-segment late loss (vessel
renarrowing) at eight months compared to TAXUS. The XIENCE V stent
is available on both over-the-wire (OTW) and rapid exchange (RX)
delivery systems. 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.
XIENCE V was approved by the U.S. Food and Drug Administration on
July 2, 2008, and was launched in Europe and other international
markets in October 2006. XIENCE V is an investigational device in
Japan and is currently under review by the Ministry of Health,
Labour and Welfare and the Pharmaceuticals and Medical Devices
Agency. Abbott also supplies a private-label version of XIENCE V to
Boston Scientific called the PROMUS(TM) Everolimus-Eluting Coronary
Stent System. PROMUS is designed and manufactured by Abbott and
supplied to Boston Scientific as part of a distribution agreement
between the two companies. 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. Additional information about XIENCE
