CAMBRIDGE, Mass.--(BUSINESS WIRE)--Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) announced today that 15 abstracts on the company’s medicines in development for hepatitis C, including its protease inhibitor, telaprevir, and polymerase inhibitor, VX-222, were accepted for presentation at the 46th Annual Meeting of the European Association for the Study of the Liver (EASL) in Berlin, Germany, March 30 to April 3, 2011.
“Telaprevir in Combination with Peginterferon Alfa-2a and Ribavirin Increased Sustained
Virologic Response Rates in Treatment-Naïve Patients Regardless of Race or Ethnicity”
Highlights of data presentations include:
Complete results from the pivotal Phase 3 REALIZE study will be presented for the first time. Topline results from this study, which evaluated telaprevir in combination with pegylated-interferon and ribavirin in people who had not achieved a viral cure (SVR) with currently available medicines, were announced in September 2010.
The first data from an ongoing Phase 2 study evaluating 12- and 24-week response-guided regimens of telaprevir and VX-222 in combination with pegylated-interferon and ribavirin will be presented during a late-breaker session (Abstract #1363).
Retrospective analyses of the relationship between IL28B genotype status and rates of viral cure with telaprevir-based combination therapy from the pivotal Phase 3 studies of REALIZE and ADVANCE will also be presented.
The titles of the abstracts related to Vertex’s medicines in development for hepatitis C are included below and the complete abstracts are now available through the EASL website at http://www.easl.eu/.
“This is an exciting time for the treatment of hepatitis C and for Vertex,” said Robert Kauffman, M.D., Ph.D., Senior Vice President and Chief Medical Officer for Vertex. “At EASL, we will present, for the first time, complete results from the Phase 3 REALIZE study and early findings of a new study evaluating both of our oral medicines in development for hepatitis C, telaprevir and VX-222 in combination with available medicines.”
The regulatory applications for the approval of telaprevir have been granted Priority Review by the U.S. Food and Drug Administration (FDA) and Health Canada and accelerated assessment by the European Medicines Agency for the treatment of people chronically infected with genotype 1 hepatitis C virus (HCV). The applications include data from three registrational studies, ADVANCE, ILLUMINATE and REALIZE, which evaluated telaprevir in people with hepatitis C who were new to treatment as well as those who did not achieve a viral cure after treatment with currently available medicines.

About Telaprevir and VX-222
Vertex has two oral medicines in late-stage development for the treatment of hepatitis C: telaprevir and VX-222. Telaprevir is an investigational, oral inhibitor that acts directly on the HCV protease, an enzyme essential for viral replication. To date, more than 2,500 people with genotype 1 hepatitis C have received telaprevir in Phase 2 and Phase 3 studies. Vertex has received priority review for its applications for the approval of telaprevir by the U.S. FDA and Health Canada.
Vertex is developing telaprevir in collaboration with Tibotec BVBA and Mitsubishi Tanabe Pharma. Vertex has rights to commercialize telaprevir in North America. Through its affiliate, Janssen, Tibotec has rights to commercialize telaprevir in Europe, South America, Australia, the Middle East and certain other countries. Mitsubishi Tanabe Pharma has rights to commercialize telaprevir in Japan and certain Far East countries.
VX-222 is an investigational, oral, non-nucleoside inhibitor of HCV NS5B polymerase. VX-222 is currently being evaluated in combination with telaprevir, pegylated-interferon and ribavirin in a Phase 2 study. Vertex has worldwide commercial rights for VX-222.
About Hepatitis C
Hepatitis C is a serious liver disease caused by the hepatitis C virus, which is spread through direct contact with the blood of infected people and ultimately affects the liver.1 Chronic hepatitis C can lead to serious and life-threatening liver problems, including liver damage, cirrhosis, liver failure or liver cancer.1 Though many people with hepatitis C may not experience symptoms, others may have symptoms such as fatigue, fever, jaundice and abdominal pain.1 Approximately 60 percent of genotype 1 hepatitis C patients who undergo treatment with an initial 48-week regimen with pegylated-interferon and ribavirin, the currently approved medicines, do not achieve SVR,2,3,4 or viral cure.5 If treatment is not successful and a person does not achieve a viral cure, they remain at an increased risk for progressive liver disease.6,7,8.9,10
More than 170 million people worldwide are chronically infected with hepatitis C. In the United States, up to 3.9 million people have chronic hepatitis C and of those, 75 percent are unaware of their infection.11 The majority of people with hepatitis C in the United States were born between 1946 and 1964, accounting for two of every three people with chronic hepatitis C.10 Hepatitis C is the leading cause of liver transplantations in the United States and is reported to contribute to 4,600 to 12,000 deaths annually.7 By 2029, total annual medical costs in the United States for people with hepatitis C are expected to more than double, from $30 billion in 2009 to approximately $85 billion.10
