Eligibility Criteria

18 Years - 69 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Male and female subjects 18 through 69 years of age, inclusive
  • Chronic hepatitis C genotype 1
  • HCV ribonucleic acid (RNA) level > 10,000 IU/mL (by RT-PCR) at screening

  • Female subjects of child-bearing potential agreeing to use dual methods for contraception
  • Male subjects with female sexual partners agreeing to use effective birth control methods

Exclusion Criteria:

  • Prior antiviral treatment for hepatitis C
  • Co-infection with HIV or hepatitis B virus
  • Subjects with a body mass index (BMI) above 32 kg/m2
  • Current or prior history of clinical hepatic decompensation
  • Evidence of HCC
  • Uncontrolled diabetes mellitus as evidenced by HbA1C ≥ 8.5% at screening
  • Known hypersensitivity to interferon alfa or ribavirin

  • History of significant central nervous system (including CNS trauma) or seizure disorders
  • Cancer within the last 5 years, or previous cancer with a high risk of recurrence, including metastatic breast cancer; non-melanoma skin cancer is not an exclusion criterion
  • History of solid organ or bone marrow transplantation
  • Clinical or laboratory evidence of uncontrolled thyroid disease, e.g., by thyroid stimulating hormone (TSH) level > 1.2 X upper limit of normal
  • Clinically significant retinopathy; this needs to have been excluded by an eye exam performed by an ophthalmologist within the last 6 months prior to screening for subjects with hypertension or diabetes mellitus
  • Drug abuse or alcohol consumption within the last 6 months which, in the opinion of the investigator, may affect study participation or outcome. Subjects in a supervised methadone treatment program on a stable regimen for > 6 months may be considered

5. Study Description

Brief Summary
The purpose of the study was to assess in subjects with chronic hepatitis C (treatment-naïve, genotype 1) receiving weight-based doses of ribavirin the virologic response to 3 dose levels of Locteron™, dosed every 2 weeks, in comparison with PEG-Intron™ dosed weekly.
Detailed Description
The aim of SELECT-2 study was to compare the safety and efficacy of Locteron to PegIntron. SELECT-2 was a 72-week Phase 2b, multicenter, international trial of treatment-naïve genotype-1 chronic HCV subjects who were randomized 1:1:1:1 and dosed with one of three doses [640ug (n=29), 480ug (n=29), 320ug (n=28)] of q2week Locteron or weekly doses of 1.5ug/kg PEG2b (n=30). Subjects received these regimens in combination with weight-based ribavirin (800-1400 mg) for up to 48 weeks. Subjects and staff were blinded to Locteron dose for the first 12 weeks. Subjects without early virologic response by 12 weeks, and without viral negativity by 24 weeks, discontinued treatment for lack of efficacy. Adverse events including flu symptoms and depression, Beck Depression Inventory (BDI), Short Form-36, HCV RNA and safety labs were measured at standard intervals at clinic visits through Week 72. In addition, daily subject self-reports of flu symptoms using an electronic subject reporting tool (ePRO) were collected for the first 12 weeks.
