Sofosbuvir With Peginterferon Alfa 2a and Ribavirin for 12 Weeks in Treatment-Naive Subjects With Chronic Genotype 1, 4, 5, or 6 HCV Infection

This study was to assess whether sofosbuvir in combination with ribavirin (RBV) and pegylated interferon alfa 2a (PEG) administered for 12 weeks is safe and effective in patients with hepatitis C virus (HCV) genotypes 1, 4, 5 , or 6 as assessed by the rate of sustained viral response (SVR) 12 weeks after discontinuation of therapy (SVR12).

  • Cirrhosis determination
  • Subject met the following classifications:
  • Treatment-naive
  • Screening laboratory values within defined thresholds
  • Not treated with any investigational drug or device within 30 days of screening

Treatment and study plan

Sofosbuvir

Drug

Sofosbuvir 400 mg tablet administered orally once daily

Other names: Sovaldi®, GS-7977, PSI-7977

RBV

Drug

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

Other names: Ribasphere®

PEG

Drug

Pegylated interferon alfa-2a (PEG) 180 μg administered once weekly by subcutaneous injection

Other names: PEGASYS®

Primary outcomes

  1. Percentage of Participants Achieving Sustained Virologic Response (SVR)12

    Time frame: Posttreatment Week 12

    SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ; ie, 25 IU/mL) 12 weeks after cessation of therapy.

  2. Number of Participants Experiencing Adverse Events Leading to Permanent Discontinuation of Study Drug

    Time frame: Baseline to Week 12

    The number of participants experiencing adverse events leading to permanent discontinuation of study drug was summarized. Adverse events may or may not have been related to study treatment. Participants discontinuing study drug were permitted to remain on the study for further assessments.

Secondary outcomes

  1. Percentage of Participants Achieving SVR4

    Time frame: Posttreatment Week 4

    SVR4 was defined as HCV RNA < LLOQ 4 weeks after cessation of therapy

  2. Percentage of Participants Achieving SVR24

    Time frame: Posttreatment Week 24

    SVR24 was defined as HCV RNA < LLOQ 24 weeks after cessation of therapy

  3. Percentage of Participants With Viral Breakthrough

    Time frame: Baseline to Week 12

    Viral breakthrough was defined as HCV RNA ≥ LLOQ after having previously had HCV RNA < LLOQ while receiving treatment, confirmed with 2 consecutive values (second confirmation value could be posttreatment), or last available on-treatment measurement with no subsequent follow-up values.

  4. Percentage of Participants With Viral Relapse

    Time frame: End of treatment to post-treatment Week 24

    Viral 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.
