    Participants infected with HCV GT3 received 800 mg MK-8876 q.d. by mouth for 7 days.

    Participants infected with HCV GT1a received 800 mg MK-8876 q.d. by mouth for 7 days.

    Outcomes

    Primary Outcome Measures

    Mean Change From Baseline in HCV Viral Load
    The mean change (log10) in HCV ribonucleic acid (RNA) from baseline to Day 7 was determined for each panel of participants.

    Secondary Outcome Measures

    Area Under the Plasma Concentration-time Curve From Time Zero to 24 Hours (hr) Post-dose (AUC0-24 hr) of MK-8876
    AUC0-24hr is a measure of the mean concentration of drug in plasma after dosing to 24 hr post-dose. Plasma AUC0-24hr was calculated on Day 1 and Day 7 of MK-8876 dosing.
    Maximum Plasma Concentration (Cmax) of MK-8876
    Cmax is a measure of the maximum plasma concentration of drug post-dose. Plasma Cmax was determined on Day 1 and Day 7 of MK-8876 dosing.
    Trough Plasma Concentration (C24hr) of MK-8876
    C24hr is a measure of the plasma drug concentration 24 hours post-dose (i.e., trough concentration). Plasma C24hr was determined on Day 1 and Day 7 of MK-8876 dosing.
    Time to Maximum Plasma Concentration (Tmax) of MK-8876
    Tmax is a measure of time required to reach the maximum plasma drug concentration post-dose. Plasma Tmax was calculated on Day 1 and Day 7 of MK-8876 dosing.
    Apparent Terminal Plasma Half-life (t½) of MK-8876
    t½ is the time required for the maximum plasma drug concentration to reduce by 50% post-dose. Plasma t½ was determined on Day 7 of MK-8876 dosing.

    5. Study Description

    Brief Summary
    This adaptive design study will evaluate the safety, pharmacokinetics, and effect on hepatitis C virus (HCV) RNA levels of multiple doses of MK-8876 in participants with HCV infection. The study will consist of 4 parts evaluating participants infected with specific hepatitis C virus genotypes and up to 10 panels allowing for additional participants to enroll in each panel as specified in the study analysis. The hypothesis evaluated in the study is that a ≥2.5 log IU/mL reduction in HCV RNA from Baseline will accompany multiple dose administration of MK-8876 in participants with HCV infection.
