EDWARDS LIFESCIENCES INITIATES CLINICAL TRIAL FOR THERAPY DESIGNED TO GROW NEW BLOOD VESSELS
IRVINE, Calif., August 30, 2004 — Edwards Lifesciences Corporation (NYSE: EW), a global leader in medical technologies to treat advanced cardiovascular disease, announced today that the company has initiated the Phase I/II clinical trial of EW-A-401, a new therapeutic compound designed to stimulate the natural growth of normal blood vessels for the treatment of intermittent claudication, a symptom of peripheral artery disease (PAD). Intermittent claudication is caused by poor blood flow in the legs that results in leg muscle pain during exercise, and is the most common symptom of PAD. The compound was developed by Sangamo BioSciences, Inc. (Nasdaq: SGMO) and licensed to Edwards for use in the treatment and prevention of ischemic cardiovascular and vascular disease.
EW-A-401 encodes a zinc finger DNA-binding protein transcription factor (ZFP TF) designed to uniquely activate all isoforms of the Vascular Endothelial Growth Factor A (VEGF-A) gene to stimulate angiogenesis, or new blood vessel growth. In preclinical studies, EW-A-401 was shown to be effective in stimulating growth of functionally normal vessels and increasing blood flow in ischemic limbs.
“This unique therapy turns on the patient’s own VEGF gene and induces the body to produce multiple VEGF-A proteins,” said Dr. Frank Giordano, Director of Yale University School of Medicine’s Cardiovascular Gene Therapy Program. “This approach has been used successfully to grow functionally normal blood vessels in pre-clinical

models of PAD, and may have distinct advantages over previous approaches that have attempted to stimulate blood vessel growth by using a single VEGF gene isoform. Pre-clinical studies leading to this trial have suggested that the type of blood vessels produced when the natural VEGF gene is activated may be more normal and less ‘leaky’ than those formed in response to alternative approaches.”
“While this therapy is still in the early stages of development, Edwards is excited to have entered the clinical phase, and we are motivated by the potential benefits that this compound could offer to patients worldwide,” said Michael A. Mussallem, Edwards’ chairman and CEO. “By combining our cardiovascular knowledge with Sangamo’s proprietary gene regulation technology, we have the opportunity to develop novel new treatments for patients suffering from some of the most pervasive forms of cardiovascular disease. In the future, Edwards may pursue additional indications for the therapy, including critical limb ischemia and ischemic heart disease.”
The U.S. Food and Drug Administration cleared an Investigational New Drug (IND) filing for the clinical trial in March, 2004 and the trial began earlier this month with the treatment of the first patient at the Warren Grant Magnuson Clinical Center of the National Institutes of Health in Bethesda Maryland, just outside of Washington, DC. Designed as a double blind, placebo-controlled, dose-escalation study involving 36 patients, the trial seeks primarily to measure EW-A-401’s safety in treating intermittent claudication. In addition, investigators may gain some preliminary data on the therapy’s effectiveness in improving patients’ blood flow, walking capacity, and quality of life. If successful, the trial’s design may allow Edwards to use the data to accelerate the evaluation of the compound’s effectiveness in the second phase.
It is expected that the trial will take approximately 12 to 18 months to screen and enroll patients, with an additional six months of safety follow-up. Patients interested in participating in this trial can contact Annette Stine, the study’s research coordinator, at

Peripheral Artery Disease Affects between 8 Million and 10 Million Americans
According to the American Heart Association, PAD is estimated to affect between 8 million and 10 million people in the United States, although the condition is often under-diagnosed and undertreated. PAD is caused by blockages to the arteries that supply the legs with blood. The initial sign of PAD is leg muscle pain during exercise. As the disease progresses, patients can experience leg pain even when resting. Eventually, some PAD patients have such poor blood flow that they develop leg ulcers that do not heal.
