MIGENIX Inc. To Initiate MX-3253 HCV Viral Kinetics Study In Treatment Naive Patients; CEO Message No. 17 Released

VANCOUVER, BC and SAN DIEGO, CA, Jan. 23 /PRNewswire-FirstCall/ - MIGENIX Inc. , a clinical-stage developer of drugs for infectious and degenerative diseases, released the Company’s 17th CEO Message today. The CEO Message provides an overview of the MX-3253 and CPI-226 clinical programs for 2006 and the first half of 2007, including the Company’s plan to initiate a combination therapy viral kinetics clinical trial of celgosivir (MX-3253) in Hepatitis C virus (HCV) patients. Celgosivir is an orally administered, first- in-class alpha glucosidase 1 inhibitor, in development for the treatment of chronic HCV infections. The viral kinetics study is intended to demonstrate improved viral load kinetics (antiviral activity) in treatment-naive HCV patients when celgosivir is used in combination with interferon over a treatment period of up to 28 days. The study is expected to start early in the second quarter of calendar 2006, with results in the second half of calendar 2006.

Jim DeMesa, M.D., President and CEO of MIGENIX stated, “This viral kinetics study provides us another significant clinical result in HCV patients in 2006. In mid-year 2006 we will have results from our MX-3253 Phase IIb study in HCV ‘non-responder’ patients initiated in November 2005 with support from Schering-Plough. These results, along with the CPI-226 Phase III clinical results expected in the first half of 2007 provide us several near-term value driving opportunities”.
