Abstract 766
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
