Condition: Transplant / Liver Transplant
Investigator: Elizabeth Verna, MD
Status: Currently Recruiting
The purpose of this study is to evaluate the safety of siplizumab when used as induction immunosuppression in patients with primary sclerosing cholangitis or autoimmune hepatitis undergoing liver transplantation. Induction immunosuppression drugs are very potent anti-rejection drugs that are given immediately after transplantation to prevent rejection.…
Condition: Transplant / Liver Transplant

Status: Currently Recruiting
The purpose of this study is to learn more about the effects of functional status (also known as "frailty") using a physical test in patients with liver disease on their health outcomes. We are enrolling patients prior to liver transplantation, and will continue to assess their functional status post transplant. If you have any questions regarding…
Condition: Transplant / Stem Cell Transplant
Investigator: Pawel Muranski, MD
Status: Currently Recruiting
The purpose of this study is to test whether giving an experimental cell product can treat viral infection in patients who have conditions that cause the poor function of their immune system. The patients with infections caused by viruses such as cytomegalovirus (CMV), Epstein-Barr virus (EBV), adenovirus (ADV), BK and JC polyomaviruses (PyVs) virus may…
Condition: COVID-19 (Coronavirus)
Investigator: Melissa Stockwell, MD, MPH
Status: Currently Recruiting
We are doing this study to understand how COVID, the infection caused by a virus called SARS-CoV-2 affects the body, and why some people who got COVID are still sick many months after being infected. Help us to better understand the long-term effects of COVID. If you or your child has had COVID or is feeling the long-term effects of COVID, you might be able…
Condition: Transplant / Liver Transplant
Investigator: Marcus Pereira, MD, MPH
Status: Currently Recruiting
The primary objective is to evaluate long-term outcomes in transplant recipients with HIV who receive livers from donors with HIV compared to donors without HIV. If you have any questions regarding this study, please contact the Transplant Clinical Research Center (TCRC).
Condition: Transplant
Investigator: Marcus Pereira, MD, MPH
Status: Currently Recruiting
The primary objective is to determine whether using hearts from HIV+ donors for HIV+ recipients is safe with regard to major transplant-related and HIV-related complications. The primary outcome is patient survival at one year. If you have any questions regarding this study, please contact the Transplant Clinical Research Center (TCRC).
Condition: Transplant
Investigator: Tomoaki Kato, MD
Status: Currently Recruiting
The purpose of this study is to study the safety and feasibility of giving intestinal transplant patients CD34+ stem cells (the cells that make all the types of blood cells) obtained from their organ donor's bonemarrow as an IV infusion post-transplant. Researchers will be looking to see whether this CD34+ cell infusion might help control rejection of…
Condition: Transplant / Liver Transplant
Investigator: Steven Lobritto, MD
Status: Currently Recruiting
In this study, we will collect information from the medical record of pediatric liver transplant recipients who received live vaccines as part of their routine post-transplant care. This data will be combined with data from other centers across the United States and Canada to help give us a better understanding of the safety and efficacy of live vaccines in…
Condition: Transplant / Liver Transplant
Investigator: Tomoaki Kato, MD
Status: Currently Recruiting
The purpose of this sponsor-initiated multi-center registry is to collect additional data on the performance of the FDA Approved OCS Liver System and post-transplant clinical outcomes for patients who are transplanted with an OCS Liver perfused donor liver in the real-world setting.
