NCT00724854

Brief Summary

The objective of the study is to evaluate, in each group, the number of participants who achieve rapid virological response (RVR) after 4 weeks treatment with PegIntron and Rebetol. The study will also assess whether RVR is a reliable predictor of sustained virologic response (defined as undetectable viral load at 24 weeks post-treatment).

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Rapid Virologic Response After 4 Weeks of Treatment

    Rapid virologic response (RVR) was defined as Hepatitis C Virus Ribonucleic acid (HCV RNA) negative after 4 weeks of treatment.

    Assessed at Treatment Week 4

Secondary Outcomes (4)

  • Number of Participants Who Achieved Sustained Virologic Response (SVR)

    Assessed at 24 weeks post-treatment

  • Number of Participants With RVR Who Also Achieved SVR

    Assessed at Treatment Week 4 (RVR) and 24 weeks post-treatment (SVR)

  • Assessment of Response at Treatment Week 48 for Genotypes 2 and 3, and Treatment Week 72 for Genotypes 1, 4, and 5, in Participants With RVR

    Treatment Week 48 and Treatment Week 72

  • Assessment of Baseline Characteristics in Participants With SVR

    24 Weeks post-treatment

Study Population

Participants infected with Hepatitis C Virus (HCV) who are undergoing treatment with PegIntron and Rebetol in accordance with approved labeling at approximately 60 sites in Brazil. Participants could be treatment-naïve, undergoing re-treatment, or co-infected with Human Immunodeficiency Virus (HIV).

You may qualify if:

  • Willing to participate in the study and sign the Informed Consent Form
  • Established HCV infection, confirmed by molecular biology test (positive qualitative polymerase chain reaction \[PCR\] test)
  • Can be treatment-naïve, have retreatment, or co-infected with HIV
  • Be under treatment with PegIntron in combination with ribavirin, starting up to 14 days before the screening visit

You may not qualify if:

  • Participants who have not confirmed their willingness to participate in the study or have refused to sign the Free and Informed Consent Form
  • Prior treatment with PegIntron (combined with ribavirin or not)
  • History of alcohol abuse in the past 6 months
  • Decompensated liver disease
  • Severe heart disease
  • Decompensated thyroid disorder
  • Neoplasia
  • Type 1 diabetes mellitus - uncontrolled or hardly controlled
  • Seizures - uncontrolled
  • Primary immune deficiency
  • Men and women not using appropriate contraceptive methods
  • Pregnancy or lactation
  • For participants co-infected with HIV: HIV-related opportunistic disease in the past 6 months or CD4 count lower than 200 cells/mm\^3
