There are 2 clinical trials
Safety and Efficacy of DAAs (Daclatasvir+Asunaprevir) in patients with chronic hepatitis C and chronic renal failure will be assessed.
Last dose in this previous HCV treatment course should have occurred at least 2 months prior to screening - No baseline mutation NS5A polymorphism including L31F/I/M/V and Y93H Exclusion Criteria: - A patient who having received Daclatasvir or Asunaprevir - Pregnant women, women who are breastfeeding or who believe they may wish to become pregnant during the course of the study - Evidence of a medical condition contributing to chronic liver disease other than HCV or seropositive for HIV - Diagnosed or suspected hepatocellular carcinoma or other malignancies - Any history of, or current evidence of, clinical hepatic decompensation (e.g., ascites, encephalopathy or variceal hemorrhage) - Received solid organ or bone marrow transplant - Current alcohol or substance abuse judged by the investigator to potentially interfere with subject compliance - Significant renal, cardiovascular, pulmonary, or neurological disease and uncontrolled diabetes or hypertension in the opinion of the investigator - Known hypersensitivity to study drugs, metabolites, or formulation excipients - Who has taken investigational drugs within 2 months. --- L31F ---
A single-arm, multi-center study of HCV-1b patients without baseline non-structure protein (NS5A) resistance-associated variants. Daclatasvir (60mg/day) and asunaprevir (100 mg twice daily) plus weight-based ribavirin (1000-1200 mg/d) for 12 weeks will be prescribed.
The existence of baseline NS5A RAV "Lycine 31 (L31F/I/M)" or "Tyrosine93 (Y93H)", by using direct-sequencing with RAV of > 20%. --- L31F ---
