Dr. James Young Appointed Principal Investigator for Vasogen’s Confirmatory Study in NYHA Class II Heart Failure

MISSISSAUGA, ON, Sept. 19 /PRNewswire-FirstCall/ - Vasogen Inc. , today announced that James B. Young, MD, Chairman, Division of Medicine at the Cleveland Clinic Foundation and Medical Director, Kaufman Center for Heart Failure, has agreed to be the Global Principal Investigator and Chairman of the Steering Committee for its planned confirmatory study of Celacade(TM) in patients with NYHA Class II chronic heart failure. Dr. Young, who has played a leading role in numerous multi-center clinical trials focusing on heart failure and transplantation, led Vasogen's 2,400-patient ACCLAIM study which was completed last year and demonstrated a 39% reduction (p equals 0.0003) in the risk of death or cardiovascular hospitalizations for the large pre-defined subgroup of 689 patients with NYHA class II heart failure.

"I am extremely pleased to be participating in this important study for the purpose of confirming the impressive result seen with the pre-specified subgroup of nearly 700 patients with NYHA Class II heart failure in the ACCLAIM study," said Dr. Young. "There is clearly a need for more options to treat patients with Class II heart failure and Celacade has the potential to become a safe and effective first-in-class therapy in this progressive and devastating condition."

Vasogen recently announced plans for a confirmatory study that would support an application for regulatory approval in the United States of its Celacade technology for the treatment of patients with NYHA Class II heart failure. The planned study involves an adaptive trial design utilizing a Bayesian statistical approach; as few as 300 patients could provide sufficient data to confirm the finding in the pre-specified sub-group of ACCLAIM patients with NYHA Class II heart failure. Furthermore, the use of an adaptive clinical trial design also provides the flexibility to increase the sample size up to 600 patients, should additional data be required.

About Dr. James Young

Dr. Young's clinical research activities began during his residency and fellowship training when he was a Lipid Research Clinic (LRC) physician. He subsequently focused his efforts on heart failure and cardiac transplant therapeutics which included early experiences with dopamine receptor agonists, angiotensin-converting enzyme inhibitors, beta blockers, calcium channel blockers, angiotensin receptor blockers, many new immunosuppressants, and a variety of parenteral inotropes and vasodilators. He has collaborated extensively with his basic science research associates at the Kaufman Center for Heart Failure and the Multi-organ Transplant Center on 'bridging' and 'translational' research focused primarily on the molecular biology of cardiac remodeling, allograft arteriopathy, and transplanted heart rejection. Dr. Young has also served as the United States Principal Investigator or Co-Principal Investigator for the HOPE, RESOLVED, SPICE, VMAC, MIRACLE-ICD, ONTARGET, TRENSCEND, and CHARM multi-center clinical trials. He has published nearly 500 manuscripts and abstracts and several textbooks. Professionally, Dr. Young is most proud of his contributions to the development and administration of organ procurement programs, his efforts to secure recognition for the newly emerging cardiology subspecialty of "Heart Failure and Cardiac Transplant Medicine", and his collaborations with basic and clinical scientists.

About Heart Failure

Heart failure, most frequently resulting from coronary artery disease or hypertension, is a debilitating syndrome in which the heart's ability to function as a pump is impaired. Patients with heart failure experience a continuing decline in their health, resulting in an increased frequency of hospitalization and premature death. According to the Heart Failure Society of America, heart failure is the only major cardiovascular disease with prevalence and incidence on the rise. Heart failure, which is now often referred to as an epidemic, is estimated to affect 12 million individuals in North America and Europe and an estimated 4.4 million have NYHA Class II symptomatic impairment.

About Vasogen

Vasogen is a biotechnology company engaged in the research and commercial development of therapies designed to target the destructive inflammatory process associated with the development and progression of cardiovascular and neurodegenerative disorders. The Company's lead product, the Celacade(TM) technology, is designed to activate the immune response to apoptosis - an important physiological process that regulates inflammation. Celacade(TM) is in late-stage development for the treatment of chronic heart failure and has received European regulatory approval under the CE Mark for this indication. Vasogen is also developing a new class of drugs for the treatment of certain neuro-inflammatory disorders and is preparing to advance VP025, the lead drug candidate from this new class, into phase II development.
