BOSTON, Nov. 2 /PRNewswire/ -- UCL Liver Failure Group presented data from two studies with OCR-002 (L-ornithine phenylacetate) that suggest the potential for this novel therapeutic agent to impact multiple aspects of liver disease and its complications. OCR-002 is licensed to Ocera Therapeutics, Inc. of San Diego, California. The data, presented at the 60th annual meeting of the American Association for the Study of Liver Diseases, is comprised of a set of studies evaluating the potential for OCR-002 treatment to reduce ammonia, down-regulate inflammation, lower oxidative stress and reduce portal hypertension in a preclinical model of cirrhosis.

"With OCR-002, for the first time, we are able to reduce circulating ammonia levels in a consistent and controlled way which gives us the ability to treat complications of liver disease as well as the ability to better understand the pathophysiology of liver disease and its complications," stated Professor Rajiv Jalan M.D. at the Institute of Hepatology, UCL. This study exploring the role of ammonia on portal hypertension and nitric oxide signaling pathway involved close collaboration with the liver hemodynamics group at UCL led by Dr. Raj Mookerjee.

These two studies, presented at AASLD, are titled, "Reduction in hyperammonemia with L-ornithine phenylacetate (OCR-002) in bile-duct-ligated (BDL) cirrhotic rats restores brain eNOS activity by modulating the DDAH-ADMA pathway" and "Treatment of hyperammonemia with L-ornithine phenylacetate (OCR-002) reduces portal pressure by modulating hepatic NFKB and hepatic eNOS activity in cirrhotic rats."
