Last verified: December 2013
The purpose of this study is to determine if 48 weeks of therapy with Peginterferon Lambda plus Ribavirin is effective and safe for a treatment of chronic hepatitis C (CHC) compared to therapy with Peginterferon alfa-2a plus Ribavirin.

Condition Intervention Phase
Hepatitis C Virus (HCV)
Biological: Peginterferon Lambda-1a
Drug: Ribavirin
Biological: Peginterferon alfa-2a
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Double-Blinded, Randomized Control Study Evaluating the Efficacy and Safety of Peginterferon Lambda-1a Compared to Peginterferon Alfa-2a, Each in Combination With Ribavirin, in the Treatment of Naive Genotype 1 Chronic Hepatitis C Subjects

Further study details as provided by Bristol-Myers Squibb:

Primary Outcome Measures:
  • Proportion of subjects who develop treatment emergent cytopenic abnormalities (anemia as defined by Hb < 10 g/dL, and/or neutropenia as defined by ANC < 750 mm3 and/or thrombocytopenia as defined by platelets < 50,000 mm3) in treatment-naive subjects [ Time Frame: Up to 48 weeks of treatment ]
    • ANC = Absolute Neutrophil Count
    • Hb = Hemoglobin

Secondary Outcome Measures:
  • Proportion of subjects with Sustained Virologic Response at Post-Treatment Follow-up Week 24 (SVR24), defined as Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) < Lower Limit of Quantitation of Assay (LLOQ) [ Time Frame: At Post-Treatment Follow-up Week 24 ]
  • Proportion of subjects with Rapid Virologic Response (RVR) (HCV RNA not detected) [ Time Frame: On treatment Week 4 (of an up to 48-week treatment period) ]
  • Proportion of subjects with on-treatment Serious Adverse Events (SAEs) through end of treatment [ Time Frame: Up to 48 weeks of treatment ]
  • Proportion of subjects with dose reductions through end of treatment [ Time Frame: Up to 48 weeks of treatment ]
  • Proportion of subjects who discontinue due to Adverse Events (AEs) through end of treatment [ Time Frame: Up to 48 weeks of treatment ]
  • Proportion of subjects with on-treatment Interferon (IFN)-associated symptoms as determined by adverse event reporting [ Time Frame: Up to 48 weeks of treatment ]

    On-treatment IFN-associated symptoms are:

    • Flu-like symptoms (as defined by pyrexia or chills or pain)
    • Musculoskeletal symptoms (as defined by arthralgia or myalgia or back pain)
    • Neurological symptoms (headache or dizziness)
    • Constitutional symptoms (fatigue or asthenia)
    • Psychiatric symptoms (depression or irritability or insomnia)

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Chronic hepatitis C, Genotype 1

  • Active substance abuse
  • Use of hematologic growth factors within 90 days prior to study randomization
  • Evidence of history of cirrhosis based on radiologic criteria or biopsy results and clinical criteria
