VERTEX PHARMACEUTICALS ANNOUNCES ACCEPTANCE OF TELAPREVIR AND VCH-222 ABSTRACTS FOR PRESENTATION AT EASL ANNUAL MEETING
- PROVE 3 SVR results accepted as late-breaker oral presentation -
- First clinical results for VCH-222 in HCV patients accepted as poster presentation -
Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that three abstracts related to the hepatitis C virus (HCV) protease inhibitor telaprevir were accepted for presentation at the 44th Annual Meeting of the European Association for the Study of the Liver (EASL) in Copenhagen, Denmark, April 22-26, 2009. The accepted abstracts include a late breaker oral presentation of sustained viral response (SVR) rates from the PROVE 3 clinical trial of telaprevir in patients who failed prior HCV therapy. In addition, three abstracts related to Vertex's HCV polymerase inhibitor VCH-222 were accepted as poster presentations, including a presentation of the first clinical results for VCH-222 in HCV patients. The abstracts can be accessed through the EASL website, www.easl.ch. In accordance with the EASL embargo policy, the accepted abstract titles are provided below:

About Telaprevir and VCH-222
Telaprevir (VX-950) is an investigational oral inhibitor of HCV protease, an enzyme essential for viral replication, and is one of the most advanced investigational antiviral agents in development that specifically targets HCV. Telaprevir is in Phase 3 clinical trials in treatment-naive and treatment-failure patients.
Vertex retains commercial rights to telaprevir in North America. Vertex and Tibotec are collaborating to develop and commercialize telaprevir in Europe, South America, Australia, the Middle East and other countries. Vertex is collaborating with Mitsubishi Tanabe Pharma to develop and commercialize telaprevir in Japan and certain Far East countries.
VCH-222 is a small molecule non-nucleoside inhibitor of HCV NS5B polymerase that completed a viral kinetic study involving five treatment-naive genotype 1a and 1b HCV infected patients. In the study, VCH-222 was dosed as 750 mg twice daily. Vertex gained VCH-222 as part of its acquisition of ViroChem Pharma Inc. in March 2009. VCH-222 is in Phase 1 clinical development.
About Hepatitis C
Hepatitis C is a liver disease caused by the hepatitis C virus, which is found in the blood of people with the disease. HCV, a serious public health concern affecting 3.4 million individuals in the United States, is spread through direct contact with the blood of infected people. Though many people with HCV infection may not experience symptoms, others may have symptoms such as jaundice, abdominal pain, fatigue and fever. Chronic HCV significantly increases a person's risk for developing long-term infection, chronic liver disease, cirrhosis or death. The burden of liver disease associated with HCV infection is increasing, and current therapies typically provide sustained benefit in less than half of patients with genotype 1 HCV, the most common strain of the virus. As many as 250,000 patients in the United States have received at least one course of treatment with pegylated interferon and ribavirin but have not achieved sustained virologic response (SVR). Patients who have failed interferon-based treatment typically have few or no available treatment options, and are at risk for progressive liver disease. In a recent study, the risk of liver failure, cancer or death following unsuccessful HCV treatment was 23% after 4 years, and 43% after 8 years. (1).
