Abbott has announced at the European Society of Cardiology Congress the widespread availability of its next-generation XIENCE PRIME™ Everolimus Eluting Coronary Stent System for the treatment of coronary artery disease.

XIENCE PRIME, which received CE Mark (Conformité Européenne) in June, offers a novel stent design and a delivery system designed for flexibility and enhanced deliverability. XIENCE PRIME is now widely available in Europe and in select countries throughout Asia-Pacific and Latin America.

"Abbott's XIENCE PRIME is an improvement in design, deliverability and conformability, all of which can be distinctly observed during coronary stent procedures, in both everyday and complex lesions," said Antonio Bartorelli, M.D., director of the Interventional Cardiology Department of the Centro Cardiologico Monzino, University of Milan, Italy. "XIENCE PRIME is designed to be easily deliverable even in complex cases and very long lesions."

XIENCE PRIME utilizes the same well-studied drug biocompatible polymer as Abbott's XIENCE V® Everolimus Eluting Coronary Stent System. XIENCE PRIME is based upon the well-tested design used in the MULTI-LINK VISION® family of stents, which is the most widely used stent platform in the world – more than 2 million of Abbott's cobalt chromium stents have been implanted worldwide.

"XIENCE PRIME leverages the superior outcomes from the extensive body of clinical evidence from the SPIRIT family of clinical trials, and offers design and delivery system properties that make it even easier for a physician to appropriately reach and treat a lesion," said Patrick Serruys, M.D., Ph.D., professor of interventional cardiology at the Thoraxcenter, Erasmus University Hospital, Rotterdam, the Netherlands. "The XIENCE PRIME stent is designed to improve stent deliverability, minimize vessel injury and provide easy access to lesions in complex anatomy."

XIENCE PRIME uses cobalt chromium technology, and has one of the thinnest drug eluting stent struts available, while maintaining strength to support the vessel. It provides visibility under X-ray during the stent implantation procedure. XIENCE PRIME is available in a broad size matrix, including XIENCE PRIME SV for small vessels and XIENCE PRIME LL for long lesions.

"XIENCE PRIME reflects Abbott's commitment to innovation, and based on the positive physician feedback we've received from our post-market evaluations, XIENCE PRIME is poised to become the market-leading drug eluting stent across Europe," said Robert Hance, senior vice president, vascular, Abbott.

In the SPIRIT family of trials, XIENCE V demonstrated superiority to Boston Scientific's TAXUS® Paclitaxel Eluting Coronary Stent System in its primary endpoints in two separate randomized clinical trials. In the SPIRIT II* trial, XIENCE V demonstrated a statistically superior 69 percent reduction of in-stent late loss at six months compared to TAXUS.

In the SPIRIT III** trial, XIENCE V demonstrated a statistically superior 50 percent reduction of in-segment late loss at eight months compared to TAXUS.

Additionally, in the SPIRIT V (five) international, single-arm study of 2,663 patients in Europe and Asia-Pacific, XIENCE V demonstrated a very low 1.8 percent rate of target lesion revascularization (TLR), a 0.7 percent rate of definite/probable stent thrombosis and a 5.1 percent rate of MACE at one year, in a diverse, "real world" population of patients and lesion types. 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.

Data from the company's SPIRIT IV trial comparing XIENCE V to TAXUS will be presented at the Transcatheter Cardiovascular Therapeutics annual meeting in September 2009. 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. Across the SPIRIT family of trials, Abbott plans to study approximately 22,000 patients treated with an everolimus eluting stent.
