Condition: Obesity
Investigator: Ilene Fennoy, MD
Status: Currently Recruiting
Bariatric surgery and a once-weekly glucagon-like peptide-1 medicine both cause major weight loss in teens, but their effects on mouth and gut bacteria and on damaged blood fats tied to metabolism are still unknown. This study will collect saliva, stool, and routine blood samples from adolescents before treatment and six months later to see how these…
Condition: Obesity
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, prediabetes and metabolic…
Condition: Obesity
Investigator: Daphna Shohamy, PhD
Status: Currently Recruiting
We are researchers at Columbia studying the learning and decision making. We are looking for participants over the age of 18, who have been prescribed Trizepatide for weight loss. Participants will be asked to complete an MRI scan and play computer games. Participants earn $25 per hour. Help us understand how the GLP-1 agonists affect brain and cognition!
Condition: Obesity
Investigator: Faris Zuraikat, PhD
Status: Currently Recruiting
The purpose of this study is to assess energy balance during two different diet periods.
Condition: Obesity
Investigator: Rudolph Leibel, MD
Status: Currently Recruiting
The Physiology of the Weight Reduced State (POWERS) is a national research study designed to discover and learn what happens to the human body after weight loss and to learn why some people regain their lost weight. Understanding why this happens could help health professionals improve strategies for successful weight loss maintenance after weight loss.…
Condition: Obesity
Investigator: Judith Korner, MD
Status: Currently Recruiting
The purpose of this study is to evaluate if genetic variations are associated with the amount of weight loss with diet and while taking an FDA-approved medication for weight loss. The participation lasts ten months and includes six in-person visits at CUIMC with blood sampling and questionnaires, virtual nutritional counseling, and taking an oral weight…
Condition: Pediatrics / Child and Adolescent Health
Investigator: Ilene Fennoy, MD
Status: Currently Recruiting
We know that puberty is a major time of change! Adolescents develop new decision-making skills and independence. It is possible that some of these changes are due to the hormonal changes during puberty. One of the ways we treat transgender and gender non-conforming teens is to suppress or "block" puberty. We know that this is a safe thing to do…
Condition: Pediatrics / Child and Adolescent Health
Investigator: Lisa Eisler, MD
Status: Currently Recruiting
We are studying the effects of iron supplementation in patients undergoing surgery for scoliosis. If you are scheduled or are planning to schedule a scoliosis surgery in greater than 3 months, please contact us to determine eligibility.
Condition: Cancer / Pancreatic Cancer
Investigator: Fay Kastrinos, MD
Status: Currently Recruiting
Pancreatic cancer is a deadly disease and the best hope for improving the chances of survival is to find it early. Some patients, called "high risk", have an inherited predisposition to pancreatic cancer. Certain medical centers have started programs where "high risk patients" undergo testing, such as receiving imaging scans, to look for…
Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are conducting a research study on how insulin controls blood sugar in both healthy people and those at risk of type 2 diabetes. We are seeking adult volunteers, aged 18-65, who have body mass indices either in the lean range (18-25 kg/m2) or in the obesity range (30-45 kg/m2) but who do not have prediabetes or diabetes. Participants will undergo a…
Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are recruiting volunteers, aged 18-70, for a research study on the buildup of excessive liver fat ("fatty liver disease") in people with or at risk for type 2 diabetes because their bodies are resistant to the actions of the blood sugar-lowering hormone, insulin. To do this, we seek to temporarily induce or accentuate insulin resistance in 14…
Condition: Obesity
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 as glucose (sugar), certain fats, and other molecules related…
Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Closed
We're conducting a research study on how much insulin is needed to control blood sugar in people who are made temporarily resistant to insulin's effects. Insulin is the main hormone (chemical signal) that the body uses to lower the levels of sugar in the blood. We are interested in looking at insulin levels because we think that lowering insulin…
Condition: Cancer / Pancreatic Cancer
Investigator: Michael Kluger, MD, MPH
Status: Closed
The purpose of this study is to evaluate how safe and effective the NanoKnife System is at treating Stage 3 pancreatic adenocarcinoma. This is registry study and therefore, the NanoKnife System is not being used for study purposes. The safety and efficacy of this system will be evaluated by comparing survival rates, pain ratings, and number of adverse…
Condition: Pediatrics / Child and Adolescent Health
Investigator: Maria Kwok, MD, MPH
Status: Closed
The purpose of this study is to evaluate the effectiveness and adverse reactions of the various types of noninvasive positive pressure supportive use in the management of children with moderate to severe acute asthma exacerbation.
Condition: Cancer / Pancreatic Cancer
Investigator: Gulam Manji, MD, PhD
Status: Closed
The purpose of this study is to learn which treatment works best in patients with pancreatic cancer. The study explores multiple treatment combinations. A study drug called atezolizumab may be combined with other drugs such as cobimetinib, PEGPH20, and BL-8040. Patients may also be assigned to receive standard chemotherapy treatment.
Condition: Cancer / Pancreatic Cancer
Investigator: Karie D. Runcie, MD
Status: Closed
The purpose of this study is to find out which doses of talimogene laherparepvec (T-Vec) can be given safely to patients with pancreatic cancer that is either too big to be taken out by surgery or has spread to other parts of the body. The study will also see if T-Vec can cause tumor shrinkage or prevent its growth. To find out which doses are safe, all…
Condition: Cancer / Pancreatic Cancer
Investigator: Paul Oberstein, MD
Status: Closed
This research study is being conducted to see if a new treatment using a study drug called Olaparib given after platinum based chemotherapy treatments can reduce the risk of pancreatic cancer from growing back. Participants will receive either Olaparib or placebo (no contains active medication) and will stay on the research study for as long as they are not…
Condition: Cancer / Pancreatic Cancer
Investigator: Paul Oberstein, MD
Status: Closed
The purpose of this study is to test whether GVAX pancreas vaccine and CRS-207 together are safe and work better than chemotherapy to treat individuals with advanced pancreatic cancer who have received at least one prior chemotherapy treatment for metastatic cancer. This study will also look at whether CRS-207 alone is safe and works better than…
