Safety and Efficacy of Ledipasvir/Sofosbuvir (LDV/SOF) Fixed Dose Combination Tablet With Ribavirin for 12 Weeks in Treatment-naive Adults With Chronic HCV Genotype 3 Infection

This study will evaluate the antiviral efficacy, safety, and tolerability of ledipasvir/sofosbuvir (LDV/SOF) fixed dose combination (FDC) plus ribavirin (RBV) in treatment-naive adults with chronic genotype 3 hepatitis C virus (HCV) infection.

  • HCV treatment-naive
  • HCV RNA > 10,000 IU/mL at screening
  • Absence of cirrhosis or compensated cirrhosis
  • Screening laboratory values within defined thresholds
  • Use of two effective contraception methods if female of childbearing potential or sexually active male

Key Exclusion Criteria:

  • Pregnant or nursing female or male with pregnant female partner
  • Coinfection 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 the individual's treatment, assessment, or compliance with the protocol

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

Treatment and study plan

LDV/SOF

Drug

90/400 mg FDC tablet administered orally once daily

Other names: Harvoni®, GS-5885/GS-7977

RBV

Drug

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

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 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 at Weeks 1, 2, 4, 8 and 12

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

  3. Change From Baseline in HCV RNA at Weeks 1, 2, 4, 8, and 12

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

  4. 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 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.
