Heart disease is the leading cause of complications among liver transplant recipients. We know that blood pressure is a heart disease risk factor, but it is unclear how blood pressure levels affect outcomes in liver transplant recipients. We are interested in how we can better measure blood pressure levels after liver transplantation. As a participant in…
HPTN 115/Foxxy Doxy is looking at doxycycline, a well-known antibiotic that is commonly used to prevent and treat acne and some sexually transmitted infections (STIs) like gonorrhea, chlamydia, and syphilis. This study is trying to find out if taking doxycycline either after condomless sex (known as on-demand doxyPEP) or weekly doxycycline can reduce STI…
The purpose of this research study is to determine whether rosuvastatin is safe and can help people living with cirrhosis lead longer, healthier lives. The study drug, rosuvastatin, is investigational, meaning it has not yet been approved for market use for this disease condition by the United States Food and Drug Administration (FDA). Participants will…
The DROP-AKI Trial is studying whether droxidopa, an FDA-approved medication for low blood pressure, can help patients with liver cirrhosis who develop kidney problems during hospitalization.

Clostridioides difficile (C. difficile) is a bacterium (germ) that can spread from one person to another causing severe diarrhea (watery poop) that at its worst can lead to death. Pfizer has been studying an investigational vaccine to prevent diarrhea caused by C. difficile. To be part of this study you must be 65 years old or older and have one or more of…
Are you suffering from persistent symptoms that began after you were diagnosed and treated with antibiotics for Lyme Disease? This new research study aims to test a new form of treatment for people with persistent symptoms despite antibiotic treatment for Lyme disease. This treatment involves stimulating a nerve on the surface of your ear. This is called…
We are conducting a research study on the effect of high insulin levels on the buildup of excessive liver fat ("fatty liver disease") in people at risk for type 2 diabetes. We are seeking adult volunteers, ages 18-65, who have obesity with a body mass index of 30-45, and have been diagnosed with, or are at risk for, prediabetes and metabolic…
Thank you for your interest in our research! We are studying how life experiences impact brain health and memory in people with and without HIV. Your participation can help advance science and improve future care. What's involved? You'll come to the Columbia University Irving Medical Center for a one-time visit, which includes a blood draw, urine…
This study is examining how oral vancomycin, an antibiotic sometimes used to treat Primary Sclerosing Cholangitis (PSC), affects the bacteria living in the gut (the microbiome). The study is observational, meaning it does not alter medical care or prescribe treatment-participants will continue their usual therapy as decided by their doctors. The study will…
The purpose of this study is to learn about the causes of non-alcoholic fatty liver disease (NAFLD). This is the most common type of liver disease, affecting millions of people in the United States alone. The incidence of Nonalcoholic Fatty Liver Disease (NAFLD) is very similar to that of obesity, type-2 diabetes, and the metabolic syndrome, suggesting a…
This study is evaluating how well odevixibat, an approved medication for Alagille Syndrome (ALGS), works in real-world clinical practice and how safe it is for long-term use. Participants with ALGS who are receiving odevixibat as part of their usual medical care will be followed for about five years. During this time, information from routine clinic visits…
TReatment for ImmUne Mediated PathopHysiology (TRIUMPH) is a multi-center, three-arm clinical trial of immunosuppressive therapy for children with acute liver failure. This is a double-blind study, so the study doctors and participants will not know to which arm the participants are assigned. The study will determine if corticosteroids or equine anti-…
The purpose of this study is to determine whether the investigational drug (maralixibat) is safe and effective in children and participants who have cholestatic liver disease with pruritus (itch) that has been responding to other therapies, and who have no other treatment options. If you have any questions regarding this study, please contact the Transplant…
Have you been treated for Lyme Disease but continue to have brain fog or other cognitive problems? This research study will assess a non-medication non-invasive intervention to improve cognitive functioning in people with persistent cognitive problems despite prior antibiotic treatment for Lyme Disease. Participants will complete this 4 week intervention at…
This patient case registry for Lyme and other Tick-borne Diseases is a component of the Clinical Trials Network that was launched in 2021 by a grant from the Steven and Alexandra Cohen Foundation. The registry will gather general information such as demographics, medical history, and current functional status. This information will help researchers to…
The purpose of this study is to learn whether wearable technology and the biometric data (e.g. heart rate, activity level, sleep) collected from it can be useful to detect clinical changes in those with liver disease, so that in the future it may help to prevent complications. The wearable technology that will be utilized in this study is the Oura Ring.…
