The Use of Hepatitis C Positive Kidneys in Hepatitis C Negative Kidney Transplant Recipients

Study Description
Brief Summary:
This is an open-label, pilot trial to test the safety and efficacy of transplantation of kidneys from hepatitis C seropositive non-viremic (HCV Ab+/NAT-) and HCV seropositive viremic (HCV Ab+/NAT+) donors to HCV seronegative recipients on the kidney transplant waitlist. Treatment and prophylaxis will be administered using a transmission-triggered approach for the first scenario (HCV Ab+/NAT- donors, arm 1) and a prophylaxis approach for the later scenario (HCV Ab+/NAT+ donors, arm 2).

Condition or disease Intervention/treatment Phase
Kidney Transplantation Hepatitis C Drug: sofosbuvir/velpatasvir Phase 2

Detailed Description:

This is a prospective, single center, pilot, open-label study of transplantation of kidneys of HCVAb+ donors to HCVAb- recipients with subsequent therapy with sofosbuvir/velpatasvir (Epclusa®). Recipients of a kidney from HCVAb+/NAT- donors will be in arm 1 (the transmission-triggered arm) of the study. In this arm, the study will monitor HCV by measuring HCV RNA in renal transplant recipients. If HCV RNA is detected, indicating transmission of HCV, recipients will be treated with sofosbuvir/velpatasvir (Epclusa®) for 12 weeks. Virological response will be assessed at 4 weeks, end of treatment and 12 weeks after completion of therapy.

Recipients of a kidney from HCVAb+/NAT+ donors will be in arm 2 (the prophylaxis arm) of the study. In this arm, patients will be started on a 12-week course of sofosbuvir/velpatasvir (Epclusa®) immediately post-operatively and will undergo close monitoring of HCV RNA for evidence of transmission.

To be eligible for the study, subjects need to be listed for renal transplantation, be not infected with HCV, HBV or HIV, and sign informed consent.
