Vertex announces abstracts from hepatitis C program to be presented at The Liver Meeting

Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that abstracts from its hepatitis C program, including two late-breaking posters from studies of INCIVEK™ (telaprevir) tablets and VX-222, were accepted for presentation at The Liver Meeting®, the 62nd Annual Meeting of the American Association for the Study of Liver Diseases (AASLD) in San Francisco, November 4-8, 2011.

New data, including sustained viral response (SVR, or viral cure) results, from a Phase 2 study evaluating short durations of 12- and 24-week regimens of VX-222 in combination with INCIVEK (in-SEE-veck), pegylated-interferon and ribavirin in people with genotype 1 chronic hepatitis C who were new to treatment will be presented for the first time. Additionally, new data from a Phase 2 study evaluating INCIVEK combination treatment in people co-infected with genotype 1 chronic hepatitis C and human immunodeficiency virus (HIV) will be presented at the meeting. All people in this study were new to hepatitis C treatment.

"INCIVEK combination therapy has successfully increased viral cure rates and shortened total treatment time for the majority of people with hepatitis C who are being treated for the first time, but we have more to do," said Peter Mueller, Ph.D., Chief Scientific Officer and Executive Vice President of Global Research and Development at Vertex. "Our ongoing research is aimed at further improving treatment for hepatitis C by exploring the use of INCIVEK among those in critical need of more effective medicines and evaluating combinations, including some without interferon, that may offer higher cure rates and shorter treatment times."
