Arbios Commences Process to Seek European Marketing Approval for SEPET(TM)

WALTHAM, Mass., April 15 /PRNewswire-FirstCall/ -- Arbios Systems, Inc. (OTC Bulletin Board: ABOS) today announced that it has commenced the marketing authorization process in the European Union to pursue CE Marking the SEPET(TM) Liver Assist Device. The Company has engaged the British Standards Institute (BSI), one of the leading notified bodies in Europe, to assist the Company in its effort to obtain a CE Mark for SEPET, which is a sterile, disposable cartridge with proprietary membrane permeability characteristics for use in treating patients with chronic liver failure. CE Marking indicates that the product complies with the essential requirements of the relevant European health, safety and environmental protection legislation and allows sale of the product within the European Union (28 countries) and the European Free Trade Association (3 countries).

"We are pleased to announce this arrangement with BSI, and look forward to advancing our market approval and product acceptance strategy for SEPET in Europe," commented Shawn Cain, President and Chief Executive Officer of Arbios. "Importantly, based on guidance from BSI, we will seek approval of SEPET using data from our recently completed feasibility trial. If no additional clinical data are necessary, and if we meet all the requirements for CE Marking, we believe that our CE Mark filing for SEPET will be completed by the beginning of 2009. We are also seeking a European distribution, marketing, and sales partner to assist us in introducing SEPET into the European market," Mr. Cain added.

About Arbios' SEPET(TM) Liver Assist Device

The SEPET(TM) Liver Assist Device is a sterile, disposable cartridge containing microporous hollow fibers with proprietary permeability characteristics. When a patient's blood is passed through these fibers, blood plasma components of specific molecular weights are expressed through the micropores, thereby cleansing the blood of harmful impurities (e.g., hepatic failure toxins as well as various mediators of inflammation and inhibitors of liver regeneration). These substances would otherwise progressively accumulate in the patient's bloodstream during liver failure, causing hypotension, increasing risk of sepsis development and accelerating damage to the liver, lungs and other organs, including the brain and kidneys, and suppressing the function and regeneration of the liver. SEPET is designed for use with standard blood dialysis systems available in hospital intensive care units.

According to the American Liver Foundation, liver disease is among the top seven causes of death in adults in the United States between the ages of 25 and 64. In fact, one out of every 10 Americans has some form of liver disease. There is currently no satisfactory therapy available to treat patients in liver failure, other than maintenance and monitoring of vital functions and keeping patients stable through provision of intravenous fluids and blood products, administration of antibiotics and support of vital functions, such as respiration.
