Brief Summary

This is an open-label, pilot trial to test the safety and efficacy of transplantation of hearts from HCV seropositive non-viremic (HCV Ab+/NAT-) and HCV seropositive viremic (HCV Ab+/NAT+) donors to HCV seronegative recipients on the heart 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).

Detailed Description

This is a prospective, single center, pilot, open-label study of transplantation of hearts of HCVAb+ donors to HCVAb- recipients with subsequent therapy with sofosbuvir/velpatasvir (Epclusa®). Recipients of a heart from HCVAb+/NAT- donors is ARM 1 or the transmission-triggered arm of the study. In this arm, the study will monitor transmission of HCV by measuring HCV RNA in heart 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 heart from HCVAb+/NAT+ donors will be in ARM 2 or the prophylaxis arm of the study. In this arm, patients will be started on a 12-week course of sofosbuvir/velpatasvir (Epclusa®) on post-operative day 1 and will undergo close monitoring of HCV RNA for evidence of transmission as well as monitoring of adverse events from therapy.

Study Groups

HCV seropositive non-viremic (HCV Ab+/NAT-) donor

HCV seropositive non-viremic (HCV Ab+/NAT-) donor hearts to HCV seronegative recipients.

Heart recipients will be monitored for HCV for one year following transplant. When HCV RNA is detected, the transmission-triggered treatment phase will be initiated.

Recipients will be treated with 12-week oral course of sofosbuvir/velpatasvir (Epclusa®), a fixed-dose combination of a nucleotide analogue HCV NS5B polymerase inhibitor (sofosbuvir - 400mg) and a NS5A inhibitor (velpatasvir - 100mg).

Intervention: Drug: sofosbuvir/velpatasvir

HCV seropositive viremic (HCV Ab+/NAT+) donor

HCV seropositive viremic (HCV Ab+/NAT+) donor hearts to HCV seronegative recipients.

Starting post-operative day 1, heart recipients will be treated with 12-week oral course of sofosbuvir/velpatasvir (Epclusa®), a fixed-dose combination of a nucleotide analogue HCV NS5B polymerase inhibitor (sofosbuvir - 400mg) and a NS5A inhibitor (velpatasvir - 100mg).
