简要总结
The purpose of this study is to investigate durability of SVR in chronic HCV patients who achieved SVR in the previous study with TMC435-containing regimen and time for resistance associated mutations to return to baseline in chronic HCV patients who did not achieve SVR in the previous study with TMC435-containing regimen.
详细描述
This is a 3-year follow-up study in patients who completed the last post-therapy follow-up visit of the previous Phase IIb [NCT00882908, NCT00980330] or Phase III [NCT01289782, NCT01290679, NCT01281839] study in which they received TMC435, in combination with pegylated interferon and ribavirin, for the treatment of hepatitis C infection. The entire study duration for each patients will be approximately 36 months. The medical follow-up of the patients will be performed according to the local standard of care. This study will evaluate the levels of hepatitis C virus in the blood circulation, as well as safety and alpha-fetoprotein testing and the change in sequence of HCV NS3/4A region over time in patients with confirmed detectable HCV RNA at last post-therapy follow-up visit of the previous TMC435 study. In this study the development of liver disease progression will also be assessed. No medication will be administered in this study.

研究组 & 干预措施
Group 1: TMC 435 - Patients With SVR at LPVPS
Patients with sustained virologic response (SVR) who completed last post-therapy follow-up visit of the previous study (LPVPS) [Phase IIb or Phase III] in which they received a TMC435-containing regimen for the treatment of HCV infection.
干预措施: No treatment (Drug)
Group 2: TMC 435 - Patients With No SVR at LPVPS
Patients with no sustained virologic response (SVR) who completed last post-therapy follow-up visit of the previous study (LPVPS) [Phase IIb or Phase III] in which they received a TMC435-containing regimen for the treatment of HCV infection.
干预措施: No treatment (Drug)
结局指标
主要结局
Percentage of Participants With Change in Sequence of HCV NS3/4A Region Over Time in Participants With Confirmed Detectable HCV RNA (Without Q80K at Baseline) at the Last Visit of the Previous Study
时间窗: Baseline and Month 36
Sequencing was performed to assess changes in the sequence of the HCV NS3/4A protein region over time in participants with no SVR at LPVPS (ie confirmed detectable HCV RNA at the last visit of the previous study). EOS defined as last available sequencing sample. AEM and NEM represents any emerging mutation and no emerging mutation at time of failure of the previous study.
Percentage of Participants Maintaining SVR at the Last Available Visit
时间窗: Last Available Visit (Month 36 for subjects completing the study)
The SVR rate is the proportion (%) of participants with HCV RNA less than (\<) 25 International Units/milliliter (IU/mL).
Overall Percentage of Participants With Change in Sequence of HCV NS3/4A Region Over Time in Participants With Confirmed Detectable HCV RNA at the Last Visit of the Previous Study
