Investigating How Weight-Loss Surgery Affects Mouth and Gut Bacteria in Children

Condition: Obesity
Investigator: Ilene Fennoy, MD
Status: Currently Recruiting
This study is being done to learn more about how weight-loss surgery or a medicine called glucagon-like peptide-1 receptor agonist (GLP-1RA) affects the bacteria in your mouth and stool. We are also trying to understand how these changes might be connected to your liver health and cholesterol levels. This information could help doctors take better care of…

Kids MoD PAH Trial

Condition: Lung Disease / Pulmonary Hypertension
Investigator: Usha Krishnan, MD
Status: Currently Recruiting
This study is being done to determine whether early combination therapy with two study drugs called sildenafil (REVATIO) and bosentan (TRACLEER) can improve pulmonary hypertension when compared to using sildenafil alone. Pediatric pulmonary arterial hypertension (PAH) is a severe medical problem that often worsens with time. It is caused by problems with…

Weight Loss Study: Genetic Variations and Response to Naltrexone/Bupropion

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…

POWERS - Understanding Body Changes After Weight Loss

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.…

Effect of lowering insulin levels on blood sugar

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…

Temporary Insulin Resistance

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…

Biobank of Blood Samples from Overweight or Obese Patients

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…

Lowering Insulin Levels in Fatty Liver Disease

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, aged 18-70, who are overweight or obese with a body mass index of 27-50, and have been diagnosed with, or are at risk for, prediabetes.…

CLASP II TR: Edwards PASCAL Transcatheter Valve Repair System Pivotal Clinical Trial in Patients with Tricuspid Regurgitation

Condition: Valve Disease / Tricuspid Valve Disease
Investigator: Susheel Kodali, MD
Status: Currently Recruiting
The goal of this early feasibility study is to gain initial insight into the basic safety and performance of transluminal (through the blood vessels) implantation of the PASCAL System's implant (composed of man-made materials). We are trying to evaluate the safety and performance of the PASCAL System with Optimal Medical Therapy (OMT) (also known as…

TTVR Early Feasibility Study in Patients with Symptomatic Severe Tricuspid Regurgitation - Medtronic

Condition: Valve Disease / Tricuspid Valve Disease
Investigator: Susheel Kodali, MD
Status: Currently Recruiting
This is a research study for patients who have Tricuspid Regurgitation (TR), a condition that occurs when the three leaflets of the heart's tricuspid valve do not close properly causing blood to leak backward with each heartbeat. Since some of the blood leaks backward, the heart has to pump more blood with each beat to push the same amount of blood…

TRISCEND ll PIVOTAL Study of the Edwards EVOQUE Tricuspid Valve Replacement System

Condition: Valve Disease / Tricuspid Valve Disease
Investigator: Susheel Kodali, MD
Status: Closed
This is a prospective, single-arm, multi-center, early feasibility study. This research study is for patients who have Tricuspid Regurgitation (TR), a condition that occurs when the three leaflets of the heart's tricuspid valve do not close properly causing blood to leak backward with each heartbeat. Since some of the blood leaks backward, the heart…

Pancreatic Clamp Study: Lowering Insulin Levels During Temporary Insulin Resistance

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: Valve Disease / Tricuspid Valve Disease
Investigator: Susheel Kodali, MD
Status: Closed
This is a research study for patients who have Tricuspid Regurgitation (TR), a condition that occurs when the three leaflets of the hearts tricuspid valve do not close properly causing blood to leak backward with each heartbeat. Since some of the blood leaks backward, the heart has to pump more blood with each beat to push the same amount of blood forward.…

Effect of Lowering Insulin Levels on Blood Sugar

Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Closed
We are conducting a research study on how much insulin is needed to control blood sugar in people at risk for type 2 diabetes. We are seeking adult volunteers, aged 18-65, who are overweight or obese with a body mass index of 25-45 and have been diagnosed with or are at risk for prediabetes. Participants will undergo two pancreatic clamp procedures…

Investigation of an ultrasound device for pulmonary artery denervation in patients with pulmonary hypertension.

Condition: Lung Disease / Pulmonary Hypertension
Investigator: Erika Berman-Rosenzweig, MD
Status: Closed
This is a clinical research study designed to determine the safety and effectiveness of the TIVUS system, an investigational device used in the treatment of PAH. The TIVUS System is intended to treat patients with pulmonary artery hypertension by injuring the sympathetic nerves surrounding the pulmonary vasculature (denervation) using ultrasonic energy. The…
