Safety and Efficacy of Ledipasvir/Sofosbuvir Fixed-Dose Combination (FDC) With and Without Ribavirin for the Treatment of HCV

The purpose of this study is to evaluate the safety, tolerability, and antiviral efficacy of ledipasvir (LDV)/sofosbuvir (SOF) fixed-dose combination (FDC) tablets with or without ribavirin (RBV) administered for 12 and 24 weeks in treatment-naive subjects with chronic genotype 1 HCV infection.

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

Inclusion criteria

  • Age ≥ 18, with chronic genotype 1 HCV infection
  • HCV treatment-naive
  • HCV RNA > 10,000 IU/mL at screening
  • Cirrhosis determination; a liver biopsy may be required
  • Screening laboratory values within defined thresholds

Exclusion criteria

  • Pregnant or nursing female or male with pregnant female partner
  • Co-infection with HIV or hepatitis B virus (HBV)
  • Current or prior history of clinical hepatic decompensation
  • Hepatocellular carcinoma (HCC) or other malignancy (with exception of certain resolved skin cancers)

Treatment and study plan

LDV/SOF

Drug

LDV/SOF 90/400 mg FDC tablet administered orally once daily

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

RBV

Drug

RBV 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 Study Drug (SVR12)

    Time frame: Posttreatment Week 12

    SVR12 was defined as HCV RNA level < the lower limit of quantification (LLOQ, ie, < 25 copies/mL) 12 weeks after last dose of study drug.

  2. Incidence of Adverse Events Leading to Permanent Discontinuation From Any Study Drug

    Time frame: Up to 24 weeks

    The percentage of participants who experienced an adverse event leading to permanent discontinuation from any study drug was summarized.

Secondary outcomes

  1. Percentage of Participants With SVR at 4 and 24 Weeks After Discontinuation of Study Drug

    Time frame: Posttreatment Weeks 4 and 24

    SVR4 and SVR24 were defined as HCV RNA level < LLOQ at 4 and 24 weeks after discontinuation of study drug, respectively.

  2. Percentage of Participants With HCV RNA < LLOQ at Week 2

    Time frame: Week 2

  3. Percentage of Participants With HCV RNA < LLOQ at Week 4

    Time frame: Week 4

  4. Percentage of Participants With HCV RNA < LLOQ at Week 8

    Time frame: Week 8

  5. Change From Baseline in HCV RNA at Week 2

    Time frame: Baseline; Week 2

  6. Change From Baseline in HCV RNA at Week 4

    Time frame: Baseline; Week 4

  7. Change From Baseline in HCV RNA at Week 8

    Time frame: Baseline; Week 8

  8. Percentage of Participants With Virologic Failure

    Time frame: Baseline to posttreatment Week 24

    On-treatment virologic failure was defined as:

    • Breakthrough: HCV RNA ≥ LLOQ after having previously had HCV RNA < LLOQ, while on treatment, confirmed with 2 consecutive values (second confirmation value could have been posttreatment), or last available on-treatment measurement with no subsequent follow- up values, OR
    • Rebound: > 1 log10 IU/mL increase in HCV RNA from nadir while on treatment, confirmed with 2 consecutive values (second confirmation value could have been posttreatment), or last available on-treatment measurement with no subsequent follow-up values, OR
    • Nonresponse: HCV RNA persistently ≥ LLOQ through 8 weeks of treatment

    Virologic relapse was defined as HCV RNA ≥ LLOQ during the posttreatment period having achieved HCV RNA < LLOQ at end of treatment, confirmed with 2 consecutive values or last available posttreatment measurement
