Safety And Efficacy of Sofosbuvir/Velpatasvir/Voxilaprevir Fixed-Dose Combination for 12 Weeks in Adults Who Participated in a Prior Gilead-Sponsored HCV Treatment Study

The primary objectives of this study are to determine the efficacy, safety, and tolerability of treatment with sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) fixed-dose combination (FDC) for 12 weeks in participants with chronic hepatitis C virus (HCV) infection with or without cirrhosis, who did not achieve sustained viral response (SVR) after receiving prior treatment in a Gilead-sponsored HCV treatment study of direct-acting antiviral (DAA)-containing regimens.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Key Inclusion Criteria:

  • Chronically HCV-infected males and non-pregnant/non-lactating females aged 18 years or older who did not achieve sustained virologic response (SVR) in a prior Gilead-sponsored HCV treatment study

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Treatment and study plan

SOF/VEL/VOX

Drug

400/100/100 mg FDC tablet administered orally once daily with food

Other names: GS-7997/GS-5816/GS-9857, Vosevi®

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 Week 12

Secondary outcomes

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

    Time frame: Posttreatment Week 4

    SVR4 was defined as HCV RNA < LLOQ at 4 weeks after stopping study treatment.

  2. Percentage of Participants With HCV RNA < LLOQ On Treatment

    Time frame: Weeks 2, 4, 8, and 12

  3. Percentage of Participants With Virologic Failure

    Time frame: Up to Posttreatment Week 12

    Virologic failure was defined as:

    • On-treatment virologic failure:
    • Breakthrough (confirmed HCV RNA ≥ LLOQ after 2 consecutive HCV RNA < LLOQ), 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

  4. Change From Baseline in HCV RNA

    Time frame: Baseline; Weeks 2, 4, 8, and 12
