About this study
Official title: Transplantation of Kidneys of Hepatitis C (HCV) Seropositive Donors to HCV Seronegative Recipients With Subsequent Therapy With Sofosbuvir/Velpatasvir (Epclusa)
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).
Read the 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.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing sofosbuvir/velpatasvir in people with Kidney Transplantation and Hepatitis C, run by Amit D Tevar, MD at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 13 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 6 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Adverse Events (time frame: 5 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Nov 2025.
