Enzo Biochem Reports on Potential Biomarker for Diagnosis of Non-Alcoholic Steatohepatitis (NASH)

Could Reduce Need for Highly Invasive Procedures Now Used for NASH Diagnosis Disease Estimated to Affect Over 8 million Americans--Upwards of 30 Million Thought to Have Milder Form of Fatty Liver

NEW YORK--(BUSINESS WIRE)--

Enzo Biochem, Inc. (NYSE:ENZ) announced today that its scientific collaborators will present data from a research study identifying a possible biomarker for the diagnosis of NASH, or non-alcoholic steatohepatitis. The presentation will take place on November 5th at the American Association for the Study of Liver Diseases meeting (AASLD) in Boston.

The data suggest that alterations in the levels of GM1, an important glycolipid component of the cell membrane in T cells, may serve as a biomarker for the disease, thereby potentially reducing the need for more invasive procedures, such as liver biopsy, to make a definitive diagnosis.

This study data also indicate that there may be a correlation between alterations at the cellular level and altered physiology in the progression of NASH. This research is part of Enzo's ongoing study of EGS21(TM), the Company's candidate drug for the treatment of NASH. EGS21 is currently being evaluated in a Phase II clinical trial; results are expected in 2008.

NASH is one of the most common causes of abnormal liver pathology in the U.S. It is one stage in a disease spectrum that ranges from liver steatosis, or fatty liver, to steatohepatitis, advanced fibrosis and end-stage cirrhosis. The disease is estimated to affect 19% of the adult population and almost half of morbidly obese individuals.

Biomarkers are an important part of the drug development process as they can assist in the identification and characterization of various patient populations that might be more responsive to a particular therapy. They can also be invaluable aids in assessing the particular biochemical pathways affected by a specific therapeutic modality, thereby providing insight into its mechanism of action.

In addition to this paper, the Company's scientific collaborators will make five additional presentations dealing with the potential effect of glycolipid combinations on pancreatic injury and insulin secretion, the potential effect of EGS21 on liver cell membranes and its attenuation of immune-mediated liver damage caused by T cell activators.
