Achillion Pharmaceuticals to present clinical study data of ACH-1625 at APASL 2011

Achillion Pharmaceuticals, Inc. (Nasdaq:ACHN) today announced that data from the Company's ongoing clinical studies of ACH-1625 has been accepted for presentation at the 21st Annual Conference of the Asian Pacific Association for the Study of the Liver (APASL 2011) to be held February 17-21, 2011 in Bangkok, Thailand.  

ACH-1625 is an inhibitor of HCV NS3 protease that was discovered and is being developed by Achillion.

The presentation, entitled "Viral Kinetics Modeling of Short-term Monotherapy Data of ACH-1625, an HCV Protease Inhibitor," will be presented by Dr. Atul Agarwal, Senior Director of Computational Chemistry of Achillion. (Abstract A-315-0024-00792.) The presentation describes a mathematical analysis of HCV RNA data collected after oral administration of ACH-1625 in HCV genotype 1 infected subjects.  This analysis shows rapid and near complete hepatitis C virus clearance following ACH-1625 administration at all dose levels tested.  In addition, mathematical modeling of HCV viral kinetics provided information that allowed for subsequent dose selection for Phase II clinical development of ACH-1625.

"These data support and further demonstrate ACH-1625's robust antiviral activity," said Dr. Agarwal. "With clinical data that demonstrated reductions in viral RNA between 3-4.25 log10, these mathematical data quantitatively show the percentage of total virus cleared after five days of ACH-1625 monotherapy.  This data also identifies specific patient population characteristics."

"We are pleased to continue to put forward a large body of scientific and clinical data on ACH-1625," commented Michael D. Kishbauch, Chief Executive Officer of Achillion. "We look forward to completing the current Phase II clinical trial of ACH-1625 to further support its profile as a potential best-in-class protease inhibitor for the treatment of HCV."
