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…
This purpose of this study is to understand the interaction between two different medications, tacrolimus and Paxlovid (nirmatrelvir/ritonavir), in patients who have had a kidney transplant and are being treated by their doctor for COVID-19 infection. Tacrolimus is an oral medication that is used standardly in kidney transplant recipients to prevent…
This is a 60-month adaptive to evaluate three siplizumab-based treatment regimens in kidney transplant recipients. The purpose of this research study is to see if the anti-rejection medications that patients normally take after transplant can be reduced or stopped completely by using several medications including the investigational drug siplizumab in the…
Kidney transplant extends life, improves quality of life, and reduces healthcare costs. Unfortunately, there are not enough donated kidneys, so many people who need a transplant spend years on the waiting list. Kidneys from organ donors who have hepatitis C virus (HCV) are often thrown away, but these kidneys work well, and hepatitis C can be cured. The…
The purpose of this study is to determine if an investigational drug called tegoprubart (also known as AT1501) is safe and effective in preventing rejection in patients who are undergoing a kidney transplant for the first time. Participants will be randomly assigned to tegoprubart or standard treatment with tacrolimusat the time of transplant. If you have…
We are inviting patients with active Rheumatoid Arthritis (RA) to help us better understand how treatment options affect inflammation in soft tissues. With a combination of blood work, a full-body FDG PET-CT scan, questionnaires, and a soft tissue biopsy (from an area around the belly button), we hope to see how RA interacts with these multiple areas of…
Kidney transplant patients are at a higher risk for bone fractures compared to the general population. We are doing a clinical trial to examine the effects of 12-months of treatment with denosumab, a monoclonal antibody against RANKL, on bone density and strength as determined by bone imaging and by non-invasive measures of bone activity from blood and…
The purpose of this study is to survey study participants to determine their knowledge and attitudes towards fertility, and interest in understanding fertility management options. Recruited participants will be contacted via e-mail and invited to participate in online surveys and have hormone markers measured at the Columbia University Medical Center.
This clinical research study is for women between the ages of 35 and 42 years who are having difficulty becoming pregnant and who would like to receive treatment within an assisted reproductive technology (ART) program in order to become pregnant. The purpose of this research study is to test the safety and effectiveness of an investigation drug called FE…
The study aims to compare the effect two different RA treatments on cardiovascular health in patients who are considering a treatment change. The study is recruiting patients who are only taking methotrexate and are switching treatment due to a lack of improvement. The trial will randomize participants to take a TNF inhibitor (Enbrel or Humira) in addition…
We are doing a research study to learn more about why people with rheumatoid arthritis (RA) are prone to heart disease. We are recruiting patients diagnosed with Rheumatoid Arthritis without a personal history of heart disease. This study involves one initial full visit as described below, and a brief follow up visit that will take place approximately 2 or…
Subjects who undergo a kidney transplant require long term use of anti-rejection (immunosuppressive)drugs to prevent their body's immune system from attacking and damaging the newly transplanted kidney (rejection).The purpose of this study is to evaluate benefits and risks of two combinations(regimens) of immunosuppressive therapies: Thymoglobulin…
The purpose of this research study is to see if an investigational drug, BB3, is safe and effective forincreasing the amount of urine that a transplanted kidney will produce. An investigational drugis one that is not approved by the United States Food and Drug Administration (FDA). BB3 is agrowth factor-like drug, which means that it can affect cell…
