Lowering Insulin to Decrease Liver Fat Production

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…

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.…

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…

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…

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…

Investigating Problem Solving in Health Management

Condition: Nutrition
Investigator: Lena Mamykina, PhD
Status: Closed
We are conducting an academic study to understand how people solve problems related to health. In the study, participants will be presented with a hypothetical problem related to diabetes self-management and asked to use an online health application to explore information and propose a solution. We invite all participants between 18 and 65 years old, who…

Study of BMS-986218 Alone or in Combination with Nivolumab for Male Patients with Metastatic Castration-Resistant Prostate Cancer (mCRPC)

Condition: Cancer / Prostate Cancer
Investigator: Karie D. Runcie, MD
Status: Closed
The purpose of this study is to assess the effectiveness and safety of combining an investigational drug called BMS-986218 (also known as Anti-CTLA4-NF monoclonal antibody), or BMS-986218 plus nivolumab, with standard of care docetaxel (chemotherapy), in men who have metastatic castration-resistant prostate cancer (mCRPC) that progressed after a second-…

A study for patients with Metastatic Castration-resistant Prostate Cancer (mCRPC) using study drug JNJ-56021927

Condition: Cancer / Prostate Cancer
Investigator: Edward Gelmann, MD
Status: Closed
The purpose of this study is to compare the clinical benefit (i.e., does it help to improve or slow down the cancer) of adding study drug JNJ-56021927 to combined treatment of abiraterone acetate plus prednisone to treat patients with metastatic Castration-resistant Prostate Cancer (mCRPC). This study will also evaluate the possible side effects of study…

The Anti-Inflammatory Effects of Exercise and Peanut Consumption

Condition: Nutrition
Investigator: Richard Sloan, PhD
Status: Closed
We will enroll and randomly assign 30 sedentary, healthy overweight men and women to two groups. Participants will either start by consuming peanuts for 4 weeks, and then go on to exercise at high intensity intervals (HIIT) for 4 weeks, or the reverse order. We will test and compare the effect of peanuts and exercise on inflammation and heart rate…

Diffuse Optical Tomography in Prostate Cancer Detection and Risk Stratification - A Pilot Study

Condition: Cancer / Prostate Cancer
Investigator: Emerson Lim, MD
Status: Closed
You are being asked to join this study because you have either been diagnosed with prostate cancer and will be having surgery to remove your prostate or you will be having a prostate biopsy to look for prostate cancer. This study is looking to see if a new imaging device, diffuse optical tomography (DOT), can detect prostate cancer. We will also see if DOT…
