Zepatier For Treatment Of Hepatitis C-Negative Patients Who Receive Heart Transplants From Hepatitis C-Positive Donors (HCV)

Study Overview
=================
Brief Summary
-----------------
This study is being conducted to determine safety and effectiveness of transplanting hearts from Hepatitis C-positive donors into Hepatitis C-negative patients on the heart transplant waitlist, who will then be treated with Zepatier after transplantation.

Detailed Description
-----------------
Open-labelled pilot clinical trial of Zepatier (MK-5172 and MK-8742/Grazoprevir + Elbasvir) in at least 20 HCV-negative subjects receiving a heart transplant from a HCV-positive donor. Eligible subjects will receive a heart transplant from a deceased-donor with genotype 1 or 4 HCV, and then will receive 12 weeks of Zepatier after heart transplantation when infection with HCV is confirmed in these heart transplant recipients. Treatment will be complete after 12 weeks.

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 Evidence of end organ damage due to diabetes (e.g. retinopathy, nephropathy, ulcerations) and /or brittle diabetes mellitus (e.g. history of diabetic ketoacidosis) and/or uncontrolled diabetes as evidence by a HgbA1C of 7.5-8.5. Chronic bronchitis, chronic obstructive pulmonary disease, inability to stop smoking. Hematologic: Significant coagulation abnormalities, bleeding diatheses. Psychosocial: Profound neurocognitive impairment with absence of social support. Active mental illness or psychosocial instability Inadequate insurance or financial support for post-transplant care. Evidence of drug, tobacco or alcohol abuse within the past six months and completion of recommended therapy/services or meets satisfied parameters as indicated by social work staff and/or consult team. History of chronic non-compliance. Amyloidosis (restricted to cardiac only, without evidence of extra cardiac involvement) BMI ≥38 Active peptic ulcer disease. Severe malnutrition. Major chronic disabling illness (e.g. lupus, severe arthritis, neurologic diseases, previous stroke with profound residual). Pulmonary infarction within the past 6 weeks Severe pulmonary hypertension as evidenced by a fixed pulmonary vascular resistance of greater than 4 Wood units on appropriate medical therapy. Patient refusal to receive blood products or transfusions during heart transplant surgery. Severe chronic obstructive pulmonary disease Current clinical sepsis. Symptomatic or severe vascular disease. Chronic Kidney Disease Stage IV, Glomerular Filtration Rate < 30 History of Mantle radiation.

Donor Organ Selection Criteria: General criteria (although there can be exceptions on a case-by-case basis) Detectable HCV RNA Genotype 1 or 4 HCV Age <=55 years No history of coronary artery disease No congenital heart disease except a repaired atrial septal defect (ASD) provided the patient has normal right ventricular function No history of arrhythmia (atrial fibrilation, atrial flutter or VT) except during resuscitation from fatal event. No evidence of cirrhosis Echocardiographic criteria: Left ventricular ejection fraction (LVEF) >=50% Normal right ventricular function No left ventricular hypertrophy (LVH) - septal wall thickness <1 cm No left ventricular hypertrophy (LVH)- posterior wall thickness <1 cm No significant valvular heart disease - more than mild tricuspid regurgitation, more than mild mitral regurgitation, more than trace aortic regurgitation. No mitral or aortic stenosis. No congenital heart disease - transposition of the great vessels, ventricular septal defect (VSD), ASD, and/or single ventricle (Fontan) Right heart catheterization criteria: Right atrial pressure <=10mmHg Pulmonary capillary wedge pressure <=18mmHg CI >=2.1 l/min/m2 Pulmonary hypertension is allowed if the patient has normal right ventricular function and a normal tricuspid valve

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Zepatier (grazoprevir 100mg and elbasvir 50 mg)<br> | Drug: Zepatier<br>* 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.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Post-treatment Sustained Virologic Response (SVR) | The primary analysis will be based on a calculation of SVR rates (number of subjects with SVR; negative HCV RNA after completing Zepatier therapy) / (number of subjects treated with Zepatier post-heart transplantation) | Baseline to 24 weeks | 
| Number of Severe Adverse Events (SAE) Attributable to HCV Therapy Post-heart Transplant |  | Baseline to 52 weeks |
