Arbios Receives Conditional Approval From The FDA To Initiate Pivotal Clinical Trial For SEPET(TM)

Arbios Systems, Inc. (OTC Bulletin Board: ABOS) announced that the Company has received conditional approval from the U.S. Food and Drug Administration ("FDA") of an Investigational Device Exemption ("IDE") to begin the pivotal clinical trial for SEPET(TM), Arbios' extracorporeal (outside the body) artificial liver assist device for blood purification of chronically ill patients suffering from acute liver failure. Permission was granted to initiate the trial while the Company responds to the FDA's conditions and request for additional information. In particular, FDA has requested a survival primary endpoint, which could potentially increase the total number of patients required for the trial. The trial design proposed by the Company has a primary endpoint of a two-stage drop in hepatic encephalopathy and its secondary endpoints include several survival based endpoints. The Company is refining its position that a two-stage drop in hepatic encephalopathy is clinically meaningful and an appropriate primary endpoint for the trial. The Company is requesting a meeting with FDA to discuss this issue and to confirm the overall design of the trial.

"While we are pleased to have received FDA permission to start the SEPET pivotal trial, we will work diligently with FDA with the hope of identifying a mutually acceptable primary endpoint," commented CEO and President Shawn Cain. "We currently do not have the financial resources to fund the pivotal trial and our ability to finance the Company is contingent upon, among other issues, agreement on a primary endpoint with a reasonable number of patients required for the trial."

"Hepatic encephalopathy ("HE") represents one of the most frequent complications of cirrhosis mandating hospitalization and a two-stage improvement of HE has significant clinical benefits to patients," noted Dr. John Vierling, M.D. FACP Chairman of Arbios and Professor of Medicine and Surgery and Chief of Hepatology at the Baylor College of Medicine. "Specifically, patients with grade 3 or 4 HE are intubated in the intensive care unit ("ICU") to prevent lethal aspiration pneumonia and can be transferred out of the ICU after a reduction of 2 grades of HE, unless other complications require continued ICU care. Similarly, reduction of HE to grade 0, 1 usually permits discharge from the hospital and management as an outpatient, reducing exposure to antibiotic-resistant organisms in hospitals and eliminating risks associated with medical errors," further commented Dr. Vierling.

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(TM) 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 -- 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.
