09/01/2012 - "In this double-blind, placebo-controlled, dose-ranging study, treatment-naïve patients with HCV genotype 1 infection (n = 94) were randomized to receive open-label Peg-IFN-α-2a (180 μg/week) and RBV (1,000-1,200 mg/day) in combination with blinded placebo or vaniprevir (300 mg twice-daily [BID], 600 mg BID, 600 mg once-daily [QD], or 800 mg QD) for 28 days, then open-label Peg-IFN-α-2a and RBV for an additional 44 weeks. "
04/01/2016 - "Treatment-naive Japanese patients with HCV genotype 1 infection were randomly assigned to receive vaniprevir (300 mg twice daily) plus PR for 12 weeks then PR alone for 12 weeks, vaniprevir (300 mg twice daily) plus PR for 24 weeks, or PR alone for 48 weeks. "

01/01/2011 - "Limitations on current treatment for viral hepatitis C have led to research into new drugs in the form of two main product lines, some of which are soon to be available on the market: NS3/4ª serine-protease inhibitors (telaprevir, boceprevir, danoprevir and vaniprevir) and the NS5B RNA polymerase inhibitors (RG-7128, RG-7227, Filibuvir, ANA-598). "
06/15/2014 - "The direct-acting antivirals (DAAs) currently in development for treatment of hepatitis C fall into four categories: (i) NS3/4A protease inhibitors: ABT-450/r, faldaprevir, asunaprevir, GS-9256, vedroprevir (GS-9451), danoprevir, MK-5172, vaniprevir, sovaprevir, ACH-2684, narlaprevir and simeprevir, in addition to those that are already developed [telaprevir (Incivek®) and boceprevir (Victrelis®)], (ii) NS5A protein inhibitors: ABT-267, daclatasvir, ledipasvir, ACH-2928, ACH-3102, PPI-668, AZD-7295, MK-8742, and GSK 2336805; (iii) NS5B (nucleoside-type) polymerase inhibitors: sofosbuvir (now approved by the FDA since 6 December 2013), GS-0938, mericitabine, VX-135, ALS 2158 and TMC 649128; (iv) NS5B (non-nucleoside-type) polymerase inhibitors: VX-222, ABT-072, ABT-333, deleobuvir, tegobuvir, setrobuvir, VCH-916, VCH-759, BMS-791325 and TMC-647055.

06/01/2014 - "Treatment-experienced patients (88% white and 35% prior null responders) with HCV genotype 1 infection and compensated cirrhosis were assigned randomly to groups given vaniprevir (600 mg twice daily) with peginterferon and ribavirin for 24 weeks (n = 16), vaniprevir (600 mg twice daily) for 24 weeks with peginterferon and ribavirin for 48 weeks (n = 14), vaniprevir (300 mg twice daily) with peginterferon and ribavirin for 48 weeks (n = 15), vaniprevir (600 mg twice daily) with peginterferon and ribavirin for 48 weeks (n = 15), or placebo with peginterferon and ribavirin for 48 weeks (n = 14, control).
