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…

Investigator: Amy Rapp, PhD
Status: Closed
The goal of the project is to identify differences in learning in obsessive-compulsive disorder (OCD) by measuring the activity of the brain while participants complete computer tasks. Eligible participants will be asked questions about their medical and psychiatric history and perform tasks on a computer while an electroencephalogram (EEG) is recorded.…
Condition: Heart Disease / Heart Failure
Investigator: Nir Uriel, MD, MSc
Status: Closed
The purpose of this research study is to understand if aspirin is needed in patients heart failure implanted with the HeartMate 3. Patients with devices like the HeartMate 3 take two blood thinner medicines, specifically warfarin and aspirin. Patients implanted with devices like the HeartMate 3 experience both clotting and bleeding complications. Data…
Condition: Heart Disease / Heart Failure
Investigator: Susheel Kodali, MD
Status: Closed
This study is for patients who require an aortic valve replacement due to severe aortic stenosis.
Condition: Heart Disease / Heart Failure
Investigator: Meghan Reading Turchioe, PhD, MPH, RN
Status: Closed
We are seeking adults with cardiovascular disease who identify as Black/African American or LatinX, and/or their caregivers, as well as community health workers working in primarily Black/African American or LatinX neighborhoods of NYC, to participate in a brief (30-minute) interviews over the phone or Zoom to discuss attitudes and perceptions related to…
Condition: Heart Disease / Heart Failure
Investigator: Gabriel Sayer, MD
Status: Closed
The purpose of this trial is to evaluate the feasibility of the Doraya Catheter and measure clinical performance and safety endpoints.
Condition: Heart Disease / Heart Failure
Investigator: Justin Fried, MD
Status: Closed
The purpose of this research is to evaluate the safety and performance of an experimental system called the Aortix System. The system is being designed for use in patients hospitalized for a worsening of their heart failure symptoms and who also show signs of strain on their kidneys. The Aortix System includes a pump, which we hope may help the heart and…
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…
