Vertex to present telaprevir and VX-222 study results against hepatitis C at EASL annual meeting

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.

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.

"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.
