Title: A Phase IIa Randomized, Open-Label Study of Telaprevir (VX-950) Administered Every 12 or Every 8 Hours in Combination With Either Peg-IFN alfa2a (Pegasys) and Ribavirin (Copegus) or Peg-IFN alfa2b (PegIntron) and Ribavirin (Rebetol) in Treatment-Naive Subjects With Chronic Genotype 1 Hepatitis C Infection
Brief Summary: The purpose of this study is to explore the efficacy, safety, tolerability, pharmacokinetics (the study of the way a drug enters and leaves the blood and tissues over time), and pharmacokinetic-pharmacodynamic relationships of telaprevir administered in two different doses in combination with two standard therapies commercially available for chronic (lasting a long time) genotype 1 Hepatitis (inflammation of the liver) C virus (HCV) infection.
