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

October 19, 2018 updated by: Gilead Sciences

A Phase 2, Multicenter, Randomized, Open-Label Study to Investigate the Safety and Efficacy of Sofosbuvir + GS-5816 for 12 Weeks in Treatment-Naive Subjects 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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Posttreatment Week 12
Percentage of Participants Who Permanently Discontinued Any Study Drug Due to an Adverse Event
Time Frame: Up to 12 weeks
Up to 12 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Posttreatment Weeks 4 and 24
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.
Up to Posttreatment Week 24
