Safety and Efficacy of Sofosbuvir/Velpatasvir/Voxilaprevir Fixed-Dose Combination With or Without Ribavirin in Participants With Chronic Genotype 1 HCV Infection Previously Treated With a Direct Acting Antiviral Regimen

The primary objective of this study is to evaluate the efficacy, safety, and tolerability of the treatment with sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) fixed dose combination (FDC) ± ribavirin (RBV) in participants with chronic genotype 1 hepatitis C virus (HCV) infection and prior treatment experience with a direct acting antiviral (DAA).

Who can participate

Healthy volunteers accepted: No

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

Key Inclusion Criteria:

  • Individuals with chronic HCV genotype 1 infection
  • Documented as treatment experienced with a direct acting antiviral-containing regimen without achieving sustained viral response
  • Absence of cirrhosis or presence of compensated cirrhosis
  • Screening laboratory values within defined thresholds
  • Must use specific contraceptive methods if female of childbearing potential or sexually active male

Key Exclusion Criteria:

  • Co-infection with HIV or hepatitis B virus (HBV)
  • Current or prior history of clinical hepatic decompensation
  • Chronic use of systemic immunosuppressive agents
  • History of clinically significant illness or any other medical disorder that may interfere with individual's treatment, assessment or compliance with the protocol
  • Pregnant or a nursing female

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-7977/GS-5816/GS-9857, Vosevi®

RBV

Drug

Tablets administered orally in a divided daily dose according to package insert weight-based dosing recommendations (< 75kg = 1000 mg and ≥ 75 kg = 1200 mg)

Primary outcomes

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

    Time frame: Posttreatment Week 12

    SVR12 is 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 SOF/VEL/VOX 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 are defined as HCV RNA < LLOQ at 4 and 24 weeks after stopping study treatment, respectively.

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

    Time frame: Weeks 1, 2, 4, 8 and 12

  3. HCV RNA Change From Baseline/Day 1 Through Week 12

    Time frame: Weeks 1, 2, 4, 8, and 12

  4. Percentage of Participants With Virologic Failure

    Time frame: Up to Posttreatment Week 24

    Virologic failure is 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.
