Brief Summary

Despite many efforts to increase the size of the donor pool, there is a large and growing disparity between the number of donor kidneys and livers available for transplantation and the number of patients on the transplant waiting list. New donor pools are needed to satisfy the lack of available donor organs, along with expanded criteria for the existing donor pools.

A new standard of care now exists at most local and regional transplant centers. This new standard of care is based on the use of multiple direct-acting antiviral agents (DAAs) for treatment of hepatitis C virus (HCV) that have been approved by the Food and Drug Administration (FDA) for the treatment of hepatitis C and are associated with high HCV cure rates and minimal side effect profiles. The efficacy and tolerability of these medications has allowed the expansion of the available donor pool by making HCV antibody positive non viremic organs and HCV-viremic organs (when HCV is detectable in the blood) available to HCV-naive recipients on the organ transplantation waiting list. Expansion of this donor pool may decrease time on the waiting list and improve quality of life and survival while waiting for organ transplantation.

Study Aim:

We propose a clinical protocol to utilize solid organs from exposed and/or HCV-viremic organ donors for transplantation into HCV negative recipients.

The primary purpose of the clinical protocol is to:

Collect prospective standard of care laboratory data on the results of these interventions

Detailed Description

Once the donor is accepted for transplantation and the recipient enrolled in the innovative clinical practice, donor HCV Ab status will be requested to initiate HCV RNA viral load testing.

Donor data will be recorded as per our standard practice and as mandated by UNOS. Our University of Maryland Medical Center team will be responsible for the donor operation as per standard of care.

Hep C Ab + NAT - Donor to Naïve Recipient This group will be monitored as illustrated in figure 1. Hep C Ab+ NAT+ Donor to Naïve Recipient HCV RNA levels, liver biochemistries, and renal function will be measured 3 days after transplant. HCV Genotype will be determined after HCV RNA is >1,000 IU/mL. HCV RNA levels will be measured weekly after transplant until HCV treatment is initiated.

Due to risk of HBV reactivation with DAA therapy, Hepatitis B surface antigen, surface antibody and core antibody status will be determined prior to HCV therapy. In patients with a prior exposure to HBV (i.e. positive HBV core antibody), Hepatitis B surface antigen levels will be monitored throughout therapy.

All patients will be seen in the Hepatology clinic within 4 weeks of transplant to establish care and follow-up.

HCV Therapy DAA therapy will be prescribed to all patients according to AASLD and IDSA joint guidelines, after giving consideration to the transplanted organ, renal function, and HCV genotype. All regimens exclude administration of ribavirin.

Therapy will be initiated as soon as possible (pending initiation of oral intake and insurance approval) following organ transplantation.

DAAs will be prescribed, after which medications will then be delivered to the patient's home or to the bedside.

If therapy is delayed beyond the 4-week appointment with Hepatology post-transplant, a protocol to monitor for infection, new-onset diabetes mellitus, glomerulonephritis and severe cholestatic hepatitis will be implemented. This protocol will include weekly blood work to include: CBC with differential, hepatic function panel, basic metabolic panel, and coagulation studies.

Liver Transplant:

• Combinations of choice:

• Mavyret (glecaprevir/pibrentasvir) - Genotype 1-6
• Harvoni (ledipasvir/sofosbuvir) + Ribavirin - Genotypes 1, 4, 5, 6; GFR>30
• Epclusa (sofosbuvir/velpatasvir) + Ribavirin - Genotypes 1-6; GFR>30

Kidney Transplant:

• Combinations of choice:

• Mavyret (glecaprevir/pibrentasvir) - genotype 1-6
• Harvoni (sofosbuvir/ledipasvir) - genotype 1, 4; GFR>30 HCV Follow-Up HCV RNA, complete blood count (CBC) and liver biochemistries will be checked 4 weeks, 8 weeks, and 12 weeks after starting therapy. In patients previously exposed to HBV, HBV surface antigen will be followed qualitatively at the same intervals.

HCV RNA will also be checked 12 weeks after completion of therapy to define cure, or sustained virologic response. As part of long-term follow-up, HCV RNA will be checked annually at routine post-transplant visits.

If SVR is not achieved, a second, and if needed, third antiviral regimen will be provided to the participant at no cost.

Transplant, Post-Operative, Immunosuppression Follow Up All will be as per UMMC standard of care. Unless otherwise contraindicated, tacrolimus immune suppression will be favored, due to drug-drug interactions associated with DATs and cyclosporine.
