Angiotech Pharmaceuticals Announces Vascular Wrap(TM)/Lifespan(R) Vascular Graft Combination Product Receives Designation Of “Device” For U.S. Pivotal Study

VANCOUVER, Dec. 20 /PRNewswire-FirstCall/ - Angiotech Pharmaceuticals, Inc. today announced that its Vascular Wrap(TM) Paclitaxel-Eluting Mesh/Lifespan(R) Vascular Graft has received a designation of “device” from the Office of Combination Products at the U.S. Food and Drug Administration (FDA). This designation of “device” has historically indicated a faster regulatory and commercial timeline for a product as compared to when the FDA considers a combination product to be a “drug”.

Angiotech plans to initiate the PREVAIL (Paclitaxel Releasing Extra- Vascular Anastomosis Implant & Lifespan(R) Graft) clinical trial in the first half of 2006. PREVAIL will be designed to assess the efficacy and safety of Angiotech’s pioneering Vascular Wrap(TM) Paclitaxel-Eluting Mesh/Lifespan(R) Vascular Graft combination product in patients with end-stage renal disease who are undergoing hemodialysis.

As a combination product, the graft serves as an access port for hemodialysis and the intent of the drug-eluting mesh is to prevent the scar formation that often leads to graft failure. Currently, approximately 50 percent of these grafts require replacement or revision within one year as a result of scar formation. The cost of these graft failures is significant, estimated to be an additional US $55,000 per failure.

“We consider this decision by the Office of Combination Products as an incremental, positive step forward for our Vascular Wrap paclitaxel-eluting mesh program”, said Rui Avelar, MD, Chief Medical Officer at Angiotech. “With a ‘device’ designation for this combination ‘Graft and Vascular Wrap’ product, we expect to submit the PREVAIL data in accordance with our timelines as outlined at our Vascular Program Update meeting in New York last month.”

About Hemodialysis:

The lives of patients with end-stage renal disease are highly dependent on access to their circulatory system in order to have their blood cleaned by hemodialysis, a method of filtering out toxins in the blood by a special machine called a dialyzer. Blood must be drawn from the body, brought to the dialyzer, and then retuned. The blood is often accessed from a special port which is a synthetic graft implanted under the skin. Today there are an estimated 4.4 million people in the U.S. with end-stage renal disease. Of these patients, 250,000 undergo hemodialysis treatment and roughly half of these patients have synthetic grafts for hemodialysis access.

About the Vascular Wrap(TM) Paclitaxel-Eluting Mesh/Lifespan(R) Vascular

Graft Combination Product:

Angiotech’s Vascular Wrap(TM) Paclitaxel-Eluting Mesh/Lifespan(R) Vascular Graft combination product technology is designed to be used as a port for hemodialysis access or as a bypass for a blocked artery. It is a combination product consisting of both the Lifespan(R) Vascular Graft and the Vascular Wrap(TM) Paclitaxel-Eluting Mesh. The Lifespan(R) Vascular Graft product line component was acquired from Edwards Lifesciences in November, 2005 and is meant to serve as one of the key components for Angiotech’s initiatives in the interventional vascular field. The Vascular Wrap(TM) component is a biodegradable mesh implant incorporating Angiotech’s paclitaxel technology in a novel biomaterial with the goal of mitigating scar formation caused by graft implantation and thereby potentially enhancing graft patency rates in AV-access patients as well as in peripheral bypass procedures.

About Combination Products:

According to the FDA, a “combination product” is defined as either 1) a product comprised of two or more regulated components that are physically, chemically or otherwise combined or mixed as a single entity; 2) two or more separate products packaged together (e.g., drug and device products); or 3) provided separately but intended for use together where both are required to achieve the intended use, indication, or effect and where mutually conforming labeling is needed. The assignment of the combination product to either a “device” or “drug” designation is determined by what about the combination product is considered to be the “primary mode of action”.
