Condition: Transplant / Kidney Transplant
Investigator: Lloyd Ratner, MD, MPH, FACS
Status: Currently Recruiting
This study is testing whether a new investigational medicine called frexalimab can safely and effectively prevent kidney transplant rejection compared to tacrolimus, a standard medication currently used after transplant. Participants will be randomly assigned to receive either frexalimab (given by injection every 4 weeks) or tacrolimus (taken as capsules…
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: Hair and Skin Disorders
Investigator: Angela Christiano, PhD
Status: Currently Recruiting
The purpose of this study is to examine the causes and pathology of alopecia areata and other hair and skin disorders. Skin biopsies and blood and/or clinical information collected in the study will be used for research aiming at developing new options for the treatment of alopecia areata and other skin and hair disorders.
Condition: Hair and Skin Disorders
Investigator: Lynn Petukhova, PhD
Status: Closed
Genetic studies help us to understand why some people develop certain diseases while others don't and also provide important clues about how best to treat the disease.
Condition: Hair and Skin Disorders
Investigator: Joshua Cook, MD, PhD
Status: Closed
We are conducting a research study on how psoriasis might be caused or worsened by high levels of the blood sugar-lowering hormone insulin. We are seeking people with plaque psoriasis, ages 18-65, who are overweight or obese with a body mass index of 25-35. Participants will have blood drawn and small skin biopsies taken from psoriasis plaques and nearby…
Condition: Transplant / Kidney Transplant
Investigator: Marcus Pereira, MD, MPH
Status: Closed
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…
Condition: Transplant / Kidney Transplant
Investigator: Joshua Weiner, MD
Status: Closed
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…
Condition: Transplant / Kidney Transplant
Investigator: Elizabeth Verna, MD
Status: Closed
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…
Condition: Transplant / Kidney Transplant
Investigator: Lloyd Ratner, MD, MPH, FACS
Status: Closed
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…
Condition: Transplant / Kidney Transplant
Investigator: Thomas Nickolas, MD, MS
Status: Closed
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…
Condition: Obstetrics & Gynecology / Fertility
Investigator: Nataki Douglas, MD, PhD
Status: Closed
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.
Condition: Obstetrics & Gynecology / Fertility
Investigator: Eric Forman, MD, HCLD
Status: Closed
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…
Condition: Transplant / Kidney Transplant
Investigator: Mark Hardy, MD
Status: Closed
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…
Condition: Transplant / Kidney Transplant
Investigator: Lloyd Ratner, MD, MPH, FACS
Status: Closed
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…
