Condition: Transplant / Kidney Transplant
Investigator: Lloyd Ratner, MD, MPH, FACS
Status: Currently Recruiting
The main goal of this clinical trial is to determine if an investigational medication called VEL101 is safe, well tolerated, and effective in people receiving a new kidney transplant. Participants will be randomly assigned to 2 different doses of VEL-101 or to tacrolimus, which is standardly used post-transplant to prevent rejection. Participants will be…
Condition: COVID-19 (Coronavirus)
Investigator: Andrew Einstein, MD
Status: Currently Recruiting
We are seeking patients that have had a pre-COVID heart CT scan (Coronary Computed Tomography Angiography) that was performed at Columbia University Irving Medical Center/NewYork-Presbyterian Hospital before March of 2020. For this study, half of patients will be required to have had COVID-19 symptoms (e.g., fever, cough, shortness of breath) and would have…
Condition: Transplant / Liver Transplant
Investigator: Marcus Pereira, MD, MPH
Status: Currently Recruiting
This research is being done to better understand rejection in transplant recipients with HIV who receive kidneys 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: COVID-19 (Coronavirus)
Investigator: Melissa Stockwell, MD, MPH
Status: Currently Recruiting
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 to help us understand more about it and treat it. Even if you or your child has never had COVID, you might be able to help. We are seeking volunteers who are under 25 to join the NIH RECOVER…
Condition: Transplant / Liver Transplant
Investigator: Sloane Heller, Md
Status: Currently Recruiting
The purpose of this study is to understand how liver disease affects thinking and memory, both before and after transplant. Participants will take a cognitive test, which will be a series of tasks and questions similar to a video game, at home on their own computers, tablets, or phones. This will take approximately 45 minutes, and participants will do this…
Condition: Transplant / Liver Transplant
Investigator: Yael Nobel, MD, MS
Status: Currently Recruiting
A complication that can occur after liver transplant (LT) is rejection, in which the patient's immune system damages the transplanted liver. This complication can be prevented with immunosuppressant medications, which are routinely used after LT. The main purpose of this study is to determine if bacteria in the intestine (gut microbiome) may affect the…
Condition: COVID-19 (Coronavirus)
Investigator: Magdalena Sobieszczyk, Md
Status: Currently Recruiting
We want to assess the baseline and cumulative seroprevalence of SARS-CoV-2 using serological and molecular assays. We will also administer a survey. Findings from this study will inform; 1) our understanding of changing epidemiology of COVID-19; 2) use of serological assays and testing algorithms, and 3) approaches to managing psychosocial stress in the…
Condition: Transplant / Liver Transplant
Investigator: Elizabeth Verna, MD
Status: Currently Recruiting
The purpose of this observational research study is to identify things that contribute to outcomes in patients with alcohol-associated liver disease who are being considered for liver transplant and who have less than 6 months of sobriety. We will look at many things including images of the liver and heart, blood tests, urine tests, stool tests and liver…
Condition: Transplant / Liver Transplant
Investigator: Elizabeth Verna, MD
Status: Currently Recruiting
The main purpose of this study is to deeply characterize cognitive function in liver transplant recipients, differentiate among different causes of cognitive impairment, and identify contributors to cognitive impairment. Participants will receive a comprehensive neurological exam, cognitive assessment, neuropsychological testing, MRI of the brain, and blood…
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
Investigator: Elizabeth Verna, MD
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 / 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 bone marrow 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: 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. If you have any questions regarding this study, please contact the…
Condition: COVID-19 (Coronavirus)
Investigator: Deborah Theodore, MD
Status: Currently Recruiting
This is a study for people with symptoms of long COVID. We are looking for people over the age of 18 who are interested in participating in a study to understand whether a mindfulness meditation intervention can help improve symptoms of long COVID. Study participation lasts 6 months and is fully remote.
Condition: COVID-19 (Coronavirus)
Investigator: Michael Yin, MD
Status: Currently Recruiting
We are seeking volunteers who have been diagnosed with COVID-19 by a healthcare provider or by lab testing. We are also looking for volunteers who have never tested positive for COVID-19 and have not received a COVID-19 vaccine.

Condition: COVID-19 (Coronavirus)
Investigator: Bernard Chang, MD, PhD
Status: Currently Recruiting
The purpose of this study to examine the long-term general psychological symptoms, and identify the predictors of these psychological symptoms. The sustained psychological toll of working in a high-stress environment can have downstream impacts on health. It is therefore important to also consider how psychological factors influence physical health, for…
