Condition: Healthy Volunteers
Investigator: Eldad Hod, MD
Status: Currently Recruiting
We are studying the effects of blood donation. If you are considering donating blood at the next school blood drive, please contact us to determine eligibility. You may qualify for participation whether or not you successfully donate blood…
Condition: Healthy Volunteers
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are seeking adult volunteers with body mass index in the obesity range (30-45 kg/m2) to come in for a single study visit where they answer some health questions and have a small volume of blood drawn (25 cc/1.7 tbsp). We will measure levels of the blood sugar-lowering hormone insulin as well…
Condition: Healthy Volunteers
Investigator: Daichi Shimbo, MD
Status: Closed
The purpose of this clinical trial is to study the relationship of stress, salt excretion, and nighttime blood pressure. Blood pressure normally has a diurnal pattern: it is highest during the day and dips during the night. The effects of psychological stress can…
Condition: Endocrine & Metabolic Disease / Cushing's Disease
Investigator: Amanda Tsang
Status: Closed
The purpose of this study is to determine if measuring blood levels of proteins called POMC, AgRP, and chromogrannin A (CGA) can be used to diagnose and track tumor growth and recurrence in patients that have ACTH-dependent Cushing's syndrome, non-secreting pituitary tumors, and other neuroendocrine tumors. We invite you to…
Condition: Healthy Volunteers
Investigator: Daichi Shimbo, MD
Status: Closed
The measurement of blood pressure used to determine if a person has high blood pressure (also known as hypertension) and whether their blood pressure is controlled while taking medications that lower blood…
Condition: Endocrine & Metabolic Disease
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
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,…
Purpose 365: Study of Lenacapavir as a Once-Yearly Injection for HIV Pre-exposure Prophylaxis (PrEP)
Condition: Healthy Volunteers
Investigator: Ellen Morrison, MD, MPH
Status: Closed
PrEP (Pre-Exposure Prophylaxis) is medication that is taken to help prevent HIV infection even if they are exposed to HIV. Research is continuing to find other, more convenient types of PrEP. This study is important because people in many areas of New York City have high rates of HIV acquisition, but use of prevention…
Condition: Healthy Volunteers
Investigator: Marcella Walker, MD
Status: Closed
Celiac disease is associated with an increased risk of osteoporosis and fractures. Men with celiac disease were found to be at higher risk for metabolic bone disease compared to women with celiac disease. The mechanisms underlying metabolic bone disease in celiac disease remain incompletely understood. The goal of this study…
Condition: Endocrine & Metabolic Disease
Investigator: Aviva Sopher, MD, MS
Status: Closed
Polycystic ovary syndrome (PCOS) is a common disorder. Young women with PCOS have irregular or absence of menstruation and excessive acne and or hair on their bodies. They may have multiple cysts on their ovaries. Adolescents and women affected with PCOS are at risk of developing abnormalities in their blood including…
Condition: Healthy Volunteers
Investigator: Magdalena Sobieszczyk, Md
Status: Closed
This clinical research study is seeking healthy individuals ages 18 to 65 who do not have HIV to help researchers understand how the body's immune system responds to three investigational antibodies (VRC07-523LS, PGT121.414.LS, and PGDM1400LS) against HIV when given in different combinations and doses. This is a Phase 2 study, which means that the…
Condition: Healthy Volunteers
Investigator: Julia Wynn
Status: Closed
This study is evaluating genomic screening in Ashkenazi Jewish and Hispanic communities. Genomic screening is done by collecting a blood sample and looking at a person's genes to learn if they are at high risk for certain health problems like cancer or heart disease or are at risk to have a child…
Condition: Healthy Volunteers
Investigator: Magdalena Sobieszczyk, Md
Status: Closed
The HIV Vaccine Trials Network, Division of AIDS, and Columbia University Irving Medical Center are conducting a trial to learn about the safety and effectiveness of 3 experimental HIV vaccines. This is a first-in-human phase 1 clinical trial of experimental HIV vaccines utilizing the mRNA vaccine platform. The 3 different experimental vaccines being tested…
Condition: Healthy Volunteers
Investigator: Marc Richmond, MD
Status: Closed
Patients with hypoplastic left heart syndrome and other single right ventricle lesions who have undergone the Fontan procedure have a high risk of neurodevelopmental disorders that affect quality of life and adulthood employment. This study will leverage the ongoing National Heart, Lung, and Blood…
Condition: Healthy Volunteers
Investigator: Adam Brickman, PhD
Status: Closed
This study is associated with the Alzheimer's Disease Research Center (ADRC) at Columbia University. The study seeks to understand changes in the way the brain's structure and function are related to age, and the risk of developing memory problems, Alzheimer's disease (AD), and dementia. The study will use magnetic resonance imaging (MRI) to examine these…
Condition: Healthy Volunteers
Investigator: Ellen Morrison, MD, MPH
Status: Closed
PrEP (Pre-Exposure Prophylaxis) is medication that is taken to prevent HIV if a person is exposed to HIV. Research is ongoing to identify PrEP medications that are both convenient and effective. This study is important because women in many areas of New York City have high rates of HIV coupled with low utilization of PrEP. The…
