Excorp Medical's Bioartificial Liver System comprises a reusable instrument, disposable tubing set and the proprietary, disposable bioartificail reactor.Once approved by regulatory agencies, Excorp Medical expects this breakthrough Bioartificial Liver System technology to be both live-saving and cost effective.Certain drugs or machines are available to substitute temporarily or long-term for many organs in the body…  no comparable substitute has been developed for the liver.The liver is the largest organ in the body and performs a variety of tasks impacting all body systems… as a result liver disease has widespread effects on virtually all other organs.Excorp Medical is currently the only company approved to conduct bioartificial liver human trials within the U.S.Currently patients must receive a liver transplant or endure prolonged hospitalization at great expense to have a chance at survival.Excorp Medical Bioartificial Liver System treatments serve as a bridge to liver regeneration and transplantExcorp Medical has developed a Bioartificial Liver System for the metabolic support of patients with compromised liver function.

The First clinical use of the Excorp Medical Bioartificial Liver Support System (BLSS) in support of a 41-year-old African-American female with fulminant hepatic failure is described. The BLSS is currently in a Phase I/II safety evaluation at the the leading liver transplant center. Inclusion criteria for the study are patients with acute liver failure, any etiology, presenting with encephalopathy deteriorating beyond Parson's Grade 2. The BLSS consists of a blood pump; a heat exchanger to control blood temperature; an oxygenator to control oxygenation and pH; a bioreactor; and associated pressure and low alarm systems. Patient liver support is provided by 70-100g of porcine liver cells housed in the hollow fiber bioreactor. The patient exhibited transient hypotension and thrombocytopenia at initiation of perfusion. The only unanticipated safety event was a lowering of patient glucose level at the onset of perfusion with the BLSS that was treatable with intravenous glucose administration. Moderate changes in blood biochemistries pre- and post perfusion are indicative of liver support being provided by the BLSS. While the initial experience with the BLSS is encouraging, completion of the Phase I/II study is required in order to more fully understand the safety aspects of the BLSS.
