Detailed Description
Hepatitis C (HCV) remains the most common chronic infection in the United States with about 3 million people chronically infected. The majority of these patients in the U.S. have genotype 1 HCV infection, which has been the most difficult genotype to treat with the traditional regimen of pegylated-interferon (P-IFN) and ribavirin, leading to sustained virologic response (SVR) in less than 50% of cases. HCV is also an established risk factor for chronic kidney disease (CKD) and end-stage renal disease (ESRD) and unfortunately the treatment is even less successful in these patients mainly limited by increased medication toxicity.
In spring of 2011, the FDA approved two new direct acting antivirals (DAA) for the treatment of chronic genotype 1 HCV, boceprevir and telaprevir, to be used in combination with Peg-IFN and ribavirin. This 'triple therapy' approach has significantly increased the response rate (increased SVR rates to about 80% in those patients who had never been previously treated) representing a significant advance in the field. In addition, several response-guided therapy approaches were tested to determine if treatment duration could be shortened based upon the virologic response on treatment.
To date, there have been no studies evaluating the safety and efficacy of triple therapy in patients with ESRD. However, a single dose pharmacokinetic study of boceprevir in subjects with ESRD on hemodialysis demonstrated that the mean maximum concentration achieved by boceprevir (Cmax) and bioavailability (AUC) were comparable in patients with ESRD and in healthy subjects. Mean t½, median Tmax and mean apparent oral total clearance (CL/F) values were also similar in healthy subjects and patients with ESRD. Boceprevir exposure was also similar on dialysis and non-dialysis days. These data suggest that boceprevir does not need to be adjusted in patients with ESRD on dialysis, and that it is not removed by hemodialysis. To date, there are no studies of telaprevir in ESRD patients.
The investigators therefore aim to study the safety and efficacy of triple therapy using boceprevir in combination with P-IFN and ribavirin in patients with stage 5 CKD (defined as glomerular filtration rate (GFR) < 15 mL.min.1.73m2 on permanent hemodialysis for stage 5). In addition, given the significant toxicity of treatment in this particular patient population, the investigators aim to study the efficacy of response guided therapy in those patients who are eligible for response-guided therapy based on prior studies (treatment naïve patients, and well documented history of relapse with prior treatment with P-IFN and ribavirin).

Partial/Null Responders /Undefined Previous Response, Compensated cirrhosis: Subjects who have compensated cirrhosis, and/or were previously treated with P-IFN +/- ribavirin without SVR (including partial responders, null responders, and those previously treated without adequate documentation of response). Subjects in Group 2 will all be assigned to fixed duration therapy.Patients will be treated with P-IFN alfa 2a or P-IFN alfa 2b and ribavirin for a 4 week lead-in followed by the addition of boceprevir for a total of 48 weeks of therapy.
