VX-135 Phase 2 TrialsVertex recently announced that it has entered into two non-exclusive agreements to conduct Phase 2 proof-of-concept studies of VX-135 in combination with simeprevir (TMC435), a protease inhibitor being jointly developed by Janssen R&D Ireland and Medivir AB, and with GSK2336805, an NS5A inhibitor in development by GlaxoSmithKline (GSK). The studies with GSK2336805 and simeprevir are expected to begin in early 2013, pending discussions with regulatory authorities. Screening is expected to begin in the coming weeks for a Phase 2 study of VX-135 and ribavirin. Vertex also plans to begin a study of VX-135 and telaprevir, the company's approved protease inhibitor marketed as INCIVEK ® (telaprevir) tablets for people with chronic genotype 1 hepatitis C, in early 2013, pending discussions with regulatory authorities. All of these Phase 2 studies will evaluate safety, tolerability and viral cure rates (SVR12; undetectable hepatitis C virus 12 weeks after the end of treatment) using 12-week combination regimens.
