Brief Summary
Primary Efficacy Objective
- To assess whether a 12-week treatment course with oral 50 mg elbasvir plus 100 mg grazoprevir given in a single daily dose to treatment-naïve patients with end-stage renal disease (ESRD) and infected with genotype 4 (GT4) chronic HCV (CHC) infection can produce a sustained viral response (SVR), i.e. HCV RNA below the lower limit of quantification \[LLOQ\] for 12 weeks (SVR12) after completion of the study treatment course Secondary Objectives
- To assess the efficacy of elbasvir/grazoprevir in suppressing HCV viremia in treatment-naïve GT4 CHC patients at each scheduled visit and clinically meaningful endpoints (Week 2, 8 and 12 \[End of Treatment - EOT\]) and 24 (SVR12)
- To assess the safety and tolerability of a 12-week treatment course with elbasvir/grazoprevir in treatment-naïve patients with ESRD and infected with GT4 CHC.
- To assess liver fibrosis by non-invasive evaluation of liver stiffness (Fibroscan®) in the same patients before treatment and EOT and SVR12 Clinical hypotheses. Primary Efficacy Hypothesis \- A 12-week treatment course with elbasvir/grazoprevir in treatment-naïve patients with ESRD and infected with GT4 CHC infection will result in an HCV RNA below the LLOQ in 95% of patients within 2 weeks of treatment, and at least 95% will have an SVR12. Secondary hypotheses
- A 12-week treatment course with elbasvir/grazoprevir in ESRD GT4 treatment-naïve patients will result in undetectable viremia in 95% patients at Week 2, 4, 8 and 12 (EOT) and 24 (SVR12)
- Treatment will be safe and well-tolerated in these patients, as determined by the type and number of adverse events identified through laboratory testing, vital signs and physical examinations.
- In these patients with liver fibrosis before treatment, the liver fibrosis as assessed by non-invasive evaluation of liver stiffness (Fibroscan®) will improve by EOT and SVR12
