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…
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…
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).
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…
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…
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…
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…
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…
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…
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.…
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…
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).
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).
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…
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…
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.
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. The study, also known as C-PIC, will be looking at antibody levels and how long the virus remains in the body. We are also…
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…
Our research team at Columbia University is trying to understand the impact of COVID-19 on smell and taste (chemosensory) dysfunction among adult patients from the Greater New York City area. Current areas of study include: 1) Investigation of smell and taste recovery patterns among patients with COVID-19; 2) Studies on how recovery of smell and taste after…
We are looking for individuals over 18 years old who are interested in learning more about COVID-19 prevention research studies. We will ask you to complete a brief questionnaire to find out if you may be eligible for one of our studies. We can then schedule a phone call, teleconference, or in-person education visit so you can learn about the research we do…
