Transplanting Hepatitis C Lungs Into Negative Lung Recipients

Subject Selection Criteria

Inclusion Criteria

• 18-67 years of age
• Obtained agreement for participation from the lung transplant team
• No evident contraindication to lung transplantation other than the underlying lung disorder
• Able to travel to the University of Pennsylvania for routine post-transplant visits and study visits for a minimum of 12 months after transplantation
• No active illicit substance abuse
• 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 of birth control or remain abstinent following transplant due to risk of HCV transmission
• Inclusion criteria for treatment (not for entry as study patient) will include any detectable HCV RNA by week 4 post-lung transplantation
• Able to provide informed consent

Exclusion Criteria

• Hepatocellular carcinoma
• HIV positive
• HCV RNA positive
• Hepatitis B surface antigen and/or DNA positive
• Any chronic liver disease (excluding non-alcoholic fatty liver disease (NAFLD)) that is occurring in the setting of persistently elevated liver enzymes (patients with Alpha-1-antitrypsin lung disease without hepatic involvement are eligible)
• Significant fibrosis (≥F2 on the Fibroscan)-for patients with cystic fibrosis, the cutoff will be 11kPa (cutoff for F2 for patients with chronic cholestatic liver disease), whereas for all other patients the cutoff will be 8kPa (the cutoff for fatty liver disease used in the THINKER study).
• 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/Epclusa
• Pre-transplant treatment with amiodarone given the drug-drug interaction between amiodarone and Epclusa
• Waitlisted for a multi-organ transplant
• Patients with underlying liver disease with or without liver cirrhosis
• Patients with cystic fibrosis who have underlying liver disease
• Re-transplant candidate
• Use of ECMO or mechanical ventilation as a bridge to lung transplantation
• Inability to provide study consent
• Chronic kidney disease with GFR 10%.
• Severe malnutrition, BMI <18
• Major chronic disabling comorbidity (e.g. lupus, severe arthritis, neurologic diseases, previous stroke with profound residual).
• Symptomatic or severe vascular disease (History of CABG, Aorta-femoral surgery)

Donor Organ Selection Criteria

Broad goal: To include donors with confirmed HCV expected to have acceptable post-transplant graft outcomes based on large retrospective lung transplant studies.

Inclusion criteria for donors:

• Detectable HCV RNA
• Age ≤55 years
• PaO2/FiO2 ≥300 on FiO2 = 100% and PEEP=5
• Cigarette use history ≤20 pack years
• No evidence of cirrhosis
• No prior treatment of HCV with a DAA-based therapy
• Can be isolated hepatitis B Core IgG positive, but cannot have a detectable HBV Core IgM, HBSAg, and/or HBV DNA (positive HBV NAT test)

Donor Exclusion Criteria:

• Donation after circulatory death determination (DCDD)
• HIV positive
