ATHENAS - Retrospective Study of Compliance in Chronic Hepatitis C With Pegylated Interferon Alfa-2b/Ribavirin in Brazil (P05632)

Study Overview
=================
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.

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 physician will be filling out the case report form with the information contained in the medical record. Any dose reduction and/or doses not taken during this period will be reported through the case report form. The collection of data for virological response after Week 12 (such as virological response at the end of treatment and sustained virological response after follow-up period) will be collected prospectively through the review of medical records after the subjects have completed their entire treatment and follow-up period.
