NCT00856024

Brief Summary

This is a Phase 4, retrospective and observational, multicenter, national (Brazil), open, noncomparative, and nonrandomized study, which does not have visits. This study will be conducted in accordance to Good Clinical Practices. The procedure will be the review of medical records of patients who have already completed 12 weeks of treatment of chronic hepatitis C with peginterferon alfa-2b and ribavirin. This review will take place after the subjects have signed the informed consent form authorizing collection of these data. The collection of data for virological response after Week 12 will be collected prospectively through the review of medical records after the subjects have completed their entire treatment and follow-up period.

Outcome Measures

Primary Outcomes (1)

  • Percent of Participants Who Were Compliant to Treatment in the First 12 Weeks

    The participant was considered compliant if he/she had administered 80% of the doses of pegylated interferon alpha 2b and 80% of the doses of ribavirin that were prescribed by the physician in the first 12 weeks of treatment.

    Week 4

  • Percent of Participants Who Achieved Early Virologic Response (EVR)

    Week 12

Study Arms (3)

Group 1: Naïve patients

Patients, from Brazil, with confirmed chronic hepatitis C and who completed 12 weeks of treatment with peginterferon alfa-2b and ribavirin and who previous to this treatment had not been treated with peginterferon alfa-2b.

Biological: Peginterferon alfa-2bDrug: Ribavirin

Group 2: Re-treatment

Patients, from Brazil, with confirmed chronic hepatitis C and who completed 12 weeks of treatment with peginterferon alfa-2b and ribavirin and who previous to this treatment had been considered nonresponders or relapsing to prior treatment for chronic hepatitis C.

Biological: Peginterferon alfa-2bDrug: Ribavirin

Group 3: HIV/HCV co-infected patients

Patients, from Brazil, with confirmed chronic hepatitis C and infected with Humman Immunodeficiency Virus (HIV) who completed 12 weeks of treatment with peginterferon alfa-2b and ribavirin.

Biological: Peginterferon alfa-2bDrug: Ribavirin

Interventions

PegIntron 80 μg, PegIntron 100 μg, or PegIntron 120 μg. The duration of the complete treatment and the doses of pegylated interferon alfa 2b should have been prescribed according to local guidelines, and according to the investigating physician's orientation.
