BACKGROUND
MK-5172 is a once-daily, potent, next-generation NS3/4A protease inhibitor (PI)
-- Potent in vitro activity against a broad enzyme panel including all major hepatitis C virus (HCV) genotypes (G)1
-- In vitro activity against resistance-associated variants (RAVs) found in patients who failed therapy with first-generation PIs (boceprevir, telaprevir, and TMC-435)2
-- 5 log10 drop in HCV RNA levels in patients with HCV G1 following monotherapy of ≥30 mg once daily (qd) for 7 days3
AIM
To examine the safety and efficacy of MK-5172 administered with pegylated interferon alfa-2b (1.5 μg/kg/week) and ribavirin (PR) (600-1400 mg/day) in HCV G1 treatment-naive (TN) patients
