– Advancement of ACH-3422 Complements Achillion's Portfolio of 2 nd Generation Protease and NS5A Inhibitors Providing the Opportunity to Optimize Treatment Duration and Outcomes for All HCV Patients – – Conference Call and Webcast to be Hosted Today at 12:00pm EDT – NEW HAVEN, Conn., May 30, 2013 (GLOBE NEWSWIRE) -- Achillion Pharmaceuticals, Inc. (Nasdaq:ACHN) today announced the nomination of the preclinical compound, ACH-3422, a novel small molecule nucleotide prodrug of a uridine analog designed to inhibit HCV NS5B polymerase. This compound will be advanced as a development candidate for the treatment of chronic hepatitis C (HCV) viral infection. Achillion plans to complete regulatory submissions during the first quarter of 2014, with first-in-human studies anticipated in the first half of 2014, followed by combination development in the second half of 2014. "Our research and discovery team has always maintained the highest standards for developing proprietary best-in-class compounds, and this has led to the nomination of ACH-3422, which we are now advancing toward the clinic," commented Milind Deshpande, Ph.D., President and Chief Executive Officer. "The addition of ACH-3422 gives Achillion a portfolio of assets that also includes a 2 nd generation protease inhibitor, sovaprevir, and a 2 nd generation NS5A inhibitor, ACH-3102, which together provide Achillion the opportunity to potentially optimize treatment outcomes and duration of therapy across all HCV patients." Dr. Deshpande further commented, "Along with the nomination of this candidate, we continue our efforts to accelerate the development time-lines for our all-oral, interferon-free combination of sovaprevir and ACH-3102, our protease and NS5A inhibitors, as a regimen for the treatment of HCV. Beginning in the third quarter of 2013, we expect to begin to report interim results from the ongoing -007 clinical trial of these agents for the treatment of HCV genotype 1 treatment-naïve patients."
