Achillion Announces Preliminary Phase 1b Proof-of-Concept Data With ACH-2928 NS5A Inhibitor for the Treatment of Hepatitis C

Achieves 3.68 Log10 Reduction in HCV RNA After Three Days of Treatment

NEW HAVEN, Conn., Dec. 5, 2011 (GLOBE NEWSWIRE) -- Achillion Pharmaceuticals, Inc. (Nasdaq:ACHN), a leader in the discovery and development of small molecule drugs to combat the most challenging infectious diseases, today reported proof-of-concept data from its Phase 1b clinical trial of ACH-2928, a first-generation NS5A inhibitor, demonstrating that patients treated with ACH-2928 achieved a mean maximum 3.68 log10 reduction in HCV RNA after three-day monotherapy of 60 mg once daily. The compound also demonstrated good safety and tolerability both in healthy volunteers and in patients with chronic hepatitis C (HCV).

ACH-2928, Achillion's first generation inhibitor of the NS5A protein, was discovered through the Company's NS5A inhibitor program. Achillion also recently nominated a second-generation NS5A inhibitor, ACH-3102, which is currently undergoing IND-enabling studies and is expected to be advanced into clinical trials during the first half of 2012.

"We believe NS5A inhibitors have emerged as an important component for an all-oral, direct acting antiviral (DAA) regimen," commented Michael D. Kishbauch, President and Chief Executive Officer of Achillion. "Furthermore, NS5A inhibitors, when combined with a protease inhibitor, have achieved sustained viral responses in clinical trials in tough to treat genotype 1 HCV populations. We believe this highlights the potential to form a proprietary interferon-free DAA combination regimen for the treatment of HCV within Achillion's pipeline."

ACH-2928 Phase 1 Program

In July 2011, Achillion initiated dosing in a randomized, double-blind, placebo-controlled phase 1a/1b clinical trial to investigate the safety, tolerability, pharmacokinetic profile and antiviral activity of ACH-2928. The trial consists of three segments: assessment of single ascending oral doses (SAD) in healthy volunteers, evaluation of 3 days of oral repeat doses in subjects with genotype 1a or 1b HCV, and a 5-day multiple ascending doses segment in healthy volunteers.

During the oral repeat doses segment in subjects infected with HCV, a total of 10 patients were enrolled with 2 patients (genotype 1a) receiving placebo and 8 patients (7 genotype 1a and 1 genotype 1b) treated with 3 doses of 60 mg ACH-2928 administered once daily. No serious adverse events (SAE) were reported and there were no patient discontinuations during treatment. The mean maximum HCV RNA decline during therapy was 3.68 log10 compared to a 0.54 log10 decline for patients receiving placebo. There were no viral breakthroughs observed during ACH-2928 monotherapy.

Preliminary data from the SAD trial segment demonstrated ACH-2928 was well tolerated at all doses evaluated up to and including the maximum dose of 500 mg. There were no serious adverse events, no clinically significant changes in vital signs, electrocardiograms (ECGs), or laboratory evaluations. All reported adverse events were classified as mild or moderate, and were transient in nature.

Based upon these preliminary results, the ongoing Phase 1 study will continue to evaluate the pharmacokinetic, pharmacodynamic, and antiviral profile of ACH-2928. These Phase 1 results have been submitted for presentation at a medical meeting being held during the second quarter of 2012. In parallel, Achillion is advancing its second generation NS5A inhibitor ACH-3102 through IND-enabling studies and the Company expects to initiate clinical development during the first half of 2012.

"As we continue to evaluate ACH-2928 in this Phase 1 study, we are also working rapidly to advance ACH-3102, which has shown in preclinical studies to possess the same potent activity against genotype 1a HCV as ACH-2928, as well as enhanced activity against resistant HCV mutants that have been observed in this patient population," stated Milind Deshpande, PhD, President of Research and Development and Chief Scientific Officer. "We believe these results validate our NS5A development program, and look forward to developing an all-oral combination for clinical evaluation that includes one of our protease inhibitors and an NS5A inhibitor next year."

About NS5A Inhibitors

The NS5A protein is a clinically validated target that serves multiple functions at various stages of the HCV life cycle including involvement in virion production, interaction with host proteins and association with interferon-resistance. Achillion's NS5A inhibitors, including ACH-2928 and ACH-3102, possess potent in vitro activity against all HCV genotypes and demonstrate, in preclinical studies, additive to synergistic activity when combined with NS3 protease inhibitors, NS5B polymerase inhibitors, and ribavirin. In preclinical studies, ACH-2928 and ACH-3102 have demonstrated excellent potency, in the pico-molar range, against HCV RNA replication, including potent activity against genotype 1a while ACH-3102 has been shown to possess enhanced activity against recognized genotype 1 resistant variants.

About HCV

The hepatitis C virus infects the liver and is the most common cause of viral hepatitis, which is an inflammation of the liver. It is currently estimated that more than 170 million people are infected with HCV worldwide and The American Association of Liver Disease estimates that up to 80 percent of individuals become chronically infected following exposure to the virus. If left untreated, chronic hepatitis can lead to permanent liver damage, which can result in the development of liver cancer, liver failure or death. Few therapeutic options currently exist for the treatment of HCV infection. The current standard of care is limited by its specificity for certain types of HCV, significant side-effect profile, and injectable route of administration.

Hepatitis C;Phase 1 Trial of ACH-2928 has begun dosing

Achillion Announces Initiation of Phase 1 Trial of ACH-2928 for the Treatment of Hepatitis C
First-in-Human Trial to Evaluate Safety and Tolerability of First Generation NS5A Inhibitor in Both Healthy Subjects and Genotype 1 HCV-Infected Patients

NEW HAVEN, Conn., Jul 11, 2011 (GlobeNewswire via COMTEX) -- Achillion Pharmaceuticals, Inc. /quotes/zigman/100395/quotes/nls/achn ACHN -1.57% , a leader in the discovery and development of small molecule drugs to combat the most challenging infectious diseases, today announced that it has begun dosing in a Phase 1 clinical trial of ACH-2928, a NS5A inhibitor, being developed for the treatment of chronic hepatitis C virus (HCV) infection.

The Phase 1 clinical study is a randomized, double-blind, placebo-controlled trial to investigate the safety, tolerability, pharmacokinetic profile and antiviral activity of ACH-2928. The trial consists of three segments, including assessment of single ascending oral doses in healthy volunteers, a 5-day multiple ascending doses segment in healthy volunteers, and evaluation of 3 days of oral ascending repeat doses in subjects with genotype 1 hepatitis C infection. The trial will take place in the United States and is designed to enroll approximately 48 healthy volunteers and 20 HCV genotype 1 treatment naive patients.

"This clinical trial with our first NS5A inhibitor aims to provide us with a substantial amount of information regarding the safety and tolerability of ACH-2928, as well as insight into its potential activity against HCV genotypes 1a and 1b," commented Elizabeth A. Olek, D.O., Vice President and Chief Medical Officer of Achillion.

"Initiating clinical development with ACH-2928, the first compound advanced from our NS5A inhibitor program, represents an important step in our ultimate strategy of becoming a leader in the development of HCV combination therapies involving our protease and NS5A inhibitors," said Michael D. Kishbauch, President and Chief Executive Officer of Achillion. "Over the next few quarters, we plan to achieve human proof-of-concept on ACH-2928 and to advance an additional NS5A inhibitor into clinical development. Furthermore, we intend to obtain additional clinical results from our protease inhibitor programs including 12-week EVR results from the Phase 2a trial with ACH-1625 and to establish clinical proof-of-concept on ACH-2684, our pan-genotypic agent being evaluated in Phase 1."
