Safety and Efficacy of Sofosbuvir + Velpatasvir With or Without Ribavirin in Treatment-Naive Adults With Chronic HCV Infection

The primary objectives of this study are to evaluate the antiviral efficacy, safety, and tolerability of sofosbuvir (SOF) + velpatasvir (VEL; GS-5816) with or without ribavirin (RBV) in treatment-naive adults with chronic genotype (GT) 1, 2, 3, 4, 5, or 6 hepatitis C virus (HCV) infection.

Treatment and study plan

SOF

Drug

400 mg tablet administered orally once daily

Other names: GS-7977, PSI-7977, Sovaldi®

VEL

Drug

Tablet administered orally once daily

Other names: GS-5816

RBV

Primary outcomes

  1. Percentage of Participants With Sustained Virologic Response (SVR) 12 Weeks After Discontinuation of Therapy (SVR12)

    Time frame: Posttreatment Week 12

    SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ; ie, 15 IU/mL) at 12 weeks after stopping study treatment.

  2. Percentage of Participants Who Permanently Discontinued Any Study Drug Due to an Adverse Event

    Time frame: Up to 12 weeks

Secondary outcomes

  1. Percentage of Participants With SVR at 4 and 24 Weeks After Discontinuation of Therapy (SVR4 and SVR24)

    Time frame: Posttreatment Weeks 4 and 24

    SVR4 and SVR 24 were defined as HCV RNA < LLOQ at 4 and 24 weeks after stopping study treatment, respectively.

  2. Percentage of Participants With Virologic Failure

    Time frame: Up to Posttreatment Week 24

    Virologic failure was defined as:

    • On-treatment virologic failure:
    • Breakthrough (confirmed HCV RNA ≥ LLOQ after having previously had HCV RNA < LLOQ while on treatment), or
    • Rebound (confirmed > 1 log10 IU/mL increase in HCV RNA from nadir while on treatment), or
    • Non-response (HCV RNA persistently ≥ LLOQ through 8 weeks of treatment)
    • Virologic relapse:
    • Confirmed HCV RNA ≥ LLOQ during the posttreatment period having achieved HCV RNA < LLOQ at last on-treatment visit.
