Single Patient Protocol for Donor HCV-positive to Recipient HCV-negative Kidney Transplant in a Patient at Risk for Loss of Dialysis Access

This is a single patient, single center study evaluating if administration of pan-genotypic DAA therapy on day 3 (+/- 2 days) post-kidney transplant prevents the transmission of hepatitis C virus infection from an HCV-positive donor kidney to an HCV-negative recipient.

The patient selected for this study previously received a kidney transplant under protocol 2016P002051. Unfortunately, she experienced primary graft nonfunction due to a renal vein thrombus and acute thrombotic microangiopathy and the transplanted HCV+ kidney was removed. She continued glecaprevir and pibrentasvir for the full course (8 weeks of treatment) and was cured of HCV. However, she continues on dialysis requiring ongoing, albeit low dose, immunosuppression after her failed transplant. This causes increased risk of infection and other dialysis-related morbidity. Futhermore, she is at risk of access loss due to multiple failed fistula attempts and prior dialysis catheter line thrombosis. Of note, she also failed a trial of peritoneal dialysis due to development of a large pleural effusion (a known treatment-limiting complication of peritoneal dialysis). Thus, this young patient, is at risk of losing dialysis access which could lead to death. The MGH transplant team has now decided that she could be retransplanted with alterations in peri-transplant anticoagulation and immunosuppression (eculizumab) that they are confident should decrease her risk of peri-transplant thrombosis and recurrent TMA. Thus, we desire to expedite her access to re-transplant. Through this protocol, this recipient will be given the opportunity to accept a kidney that is HCV antibody positive and nucleic acid test (NAT) negative or HCV NAT positive and will be treated with oral glecaprevir (300mg)/pibrentasvir (120mg) (G/P, MavyretTM) on day 3 (+/- 2 days) post-kidney transplant to prevent the transmission of HCV infection at the time of transplant. Our goal is to provide access to kidney transplantation as soon as possible, with a donor of any genotype of infection, with elimination of the potential HCV infection by therapy used on day 3 (+/- 2 days) in the case of HCV NAT+ transplant and surveillance and reactive therapy in the case of HCV antibody positive NAT- transplant.

Glecaprevir (100mg) / pibrentasvir (40mg) (fixed dose combination) treatment for Hepatitis C virus (HCV)-naive recipients who receive a kidney transplant from a deceased, HCV-infected donor. Subject will receive first dose on day 3 (+/- 2 days) post-kideny transplantation and continue daily for 8 weeks.

The subject will begin an 8 week course of therapy with glecaprevir (100mg) / pibrentasvir (40mg) starting on day 3 (+/- 2 days) post-kidney transplantation from a hepatitis C positive donor.
