Experimental: Direct-acting antiviral treatment for HCV |
Drug: Zepatier
Zepatier (grazoprevir 100mg and elbasvir 50 mg once daily) is taken by mouth for 12 weeks unless a genetic variation is detected. In this case treatment with Zepatier will be extended to 16 weeks. Study subjects with treatment failure will be provided open-label Zepatier + sofosbuvir (sovaldi) 400mg + Ribavirin (generic), renally dosed based on creatinine clearance per the manufacturer guidelines. Drug: Mavyret Mavyret (glecaprevir 100 mg and pibrentasvir 40 mg) is taken by mouth for 8 weeks. Study subjects with treatment failure will be provided an alternative DAA + sofosbuvir (sovaldi) 400mg + Ribavirin (generic), renally dosed based on creatinine clearance per the manufacturer guidelines. |
- Post-treatment sustained virologic response (SVR) [ Time Frame: Baseline to 24 weeks ]The primary analysis will be based on a calculation of SVR rates (number of subjects with SVR-12; negative HCV RNA 12 weeks after completing therapy) / (number of subjects treated post-kidney transplantation)
- Major adverse events attributable to HCV therapy in post-kidney transplant patients post-kidney transplant patients. [ Time Frame: Baseline to 52 weeks ]

Ages Eligible for Study: | 30 Years to 70 Years (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Subject:
Inclusion criteria
- Must be waitlisted for a kidney transplant (dialysis is not a requirement if a patient is waitlisted)
- Listed for an isolated kidney transplant with ≤2555 days of accrued transplant waiting time and/or ≤2555 days of dialysis time for blood group A, B, or O, by enrollment
- Listed for an isolated kidney transplant with ≤1825 days of accrued transplant waiting time and/or ≤1825 days of dialysis time for blood group AB, by enrollment
- No available living kidney donor
- Between 30-70 years of age, by enrollment
- Have a panel reactive antibody level ≤97%
- eGFR <15ml/min/1.73m2 as calculated using the 4 variable MDRD equation
- Obtained agreement for participation from the patient's treating transplant nephrologist
- Able to travel to the University of Pennsylvania for routine post-transplant visits and study visits for a minimum of 6 months after transplantation
- No active illicit substance abuse
- Weigh at least 50kg
- Women must agree to use birth control in accordance with Mycophenolate Risk Evaluation and Mitigation Strategy (REMS) following transplant due to the increased risk of birth defects and/or miscarriage
- Both men and women must agree to use at least one barrier method to prevent any secretion exchange
- Inclusion criteria for treatment (not for entry as study patient) will include any detectable HCV RNA
- Able to provide informed consent
Exclusion criteria
- Hepatocellular carcinoma
- Patients with primary focal segmental glomerulosclerosis (FSGS), FSGS recurring after previous transplant, or disease process with increased risk of causing early graft failure as per the treating nephrologist
- HIV positive
- HCV RNA positive (can be isolated HCV antibody positive provided the subject has no history of previously treated HCV)
- Hepatitis B surface antigen positive
- Any other chronic liver disease (excluding non-alcoholic fatty liver disease (NAFLD) with abnormal liver enzymes
- Persistently elevated liver transaminases
- Significant hepatic fibrosis on screening elastography (≥f2 fibrosis)
- Pregnant or nursing (lactating) women
- Known allergy or intolerance to tacrolimus that would require post-transplant administration of cyclosporine, rather than tacrolimus given the drug-drug interaction between cyclosporine and Zepatier
- Waitlisted for a multi-organ transplant (e.g., pancreas-kidney, heart-kidney, etc.)
-
Significant cardiomyopathy defined as either:
- Left ventricular ejection fraction <40% on most recent echocardiogram
- Left ventricular ejection fraction ≥40% but <50% on most recent echocardiogram with an <5 METS of exercise tolerance
- Reversible ischemia on stress testing without revascularization
Donor Organ Selection:
Inclusion Criteria
- Detectable HCV RNA
- Age ≤60 years
- Study modified Kidney donor profile index (KDPI) score ≤0.856 - calculated as if the kidney were HCV-negative (https://optn.transplant.hrsa.gov/resources/allocation-calculators/kdpi-calculator/)
Exclusion Criteria
- Anatomical issues in the kidney allograft that raise the risk of post-transplant complications (e.g., number or length of renal arteries or veins)
- Confirmed HIV positive
- Confirmed HBV positive (positive Hepatitis B surface antigen and/or HBV DNA)
- Known previously failed treatment for HCV using a regimen with a direct-acting antiviral (can have received interferon monotherapy and/or interferon + ribavirin combination therapy)
