BARCELONA, Spain--(BUSINESS WIRE)--Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced data from a retrospective subanalysis of the Phase 2 PROVE 2 study that showed that 100 percent (12/12) of patients with the IL28B CC genotype who were new to treatment achieved a viral cure (sustained viral response, or SVR) with a total of 12 weeks of treatment with INCIVEK™ (telaprevir) tablets, pegylated-interferon and ribavirin. These data support Vertex’s ongoing Phase 3b study that is evaluating a total treatment duration as short as 12 weeks in people with the IL28B CC genotype. Data from the PROVE 2 subanalysis and 13 other abstracts on INCIVEK and Vertex’s medicines in development for the treatment of hepatitis C will be presented at the 47th Annual Meeting of the European Association for the Study of the Liver (EASL) in Barcelona, Spain, April 18 to 22, 2012.
