  • Patients who failed\* SOC therapy with PEG-IFN and ribavirin or triple therapy with SOC and DAA agents
  • \*Treatment failure is defined by any of the following; A. Partial response (PR) Serum HCV RNA level declined by at least 2 log10 but still detected at treatment week 24 B. Non-response (NR) Serum HCV RNA level not declined by at least 2 log10 at treatment week 12 C. Relapse Serum HCV RNA undetected during treatment but detectable after end of treatment D. Treatment discontinuation due to ADR or other reason
