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…

The Cancer of the Pancreas Screening-5 Study (CAPS5 Study)

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…

Transcranial Direct Current Stimulation (tDCS): A New Treatment of Brain Fog in Previously Treated Lyme Disease Patients

Condition: Infectious Disease / Lyme Disease
Investigator: Brian Fallon, MD
Status: Currently Recruiting
Have you been treated for Lyme Disease but continue to have brain fog or other cognitive problems? This research study will assess a non-medication non-invasive intervention to improve cognitive functioning in people with persistent cognitive problems despite prior antibiotic treatment for Lyme Disease. Participants will complete this 4 week intervention at…

Clinical Research Registry for Lyme and Other Tick-borne Diseases

Condition: Infectious Disease / Lyme Disease
Investigator: Brian Fallon, MD
Status: Currently Recruiting
This patient case registry for Lyme and other Tick-borne Diseases is a component of the Clinical Trials Network that was launched in 2021 by a grant from the Steven and Alexandra Cohen Foundation. The registry will gather general information such as demographics, medical history, and current functional status. This information will help researchers to…

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…

Registry Study to Evaluate the Nanoknife System in Treating Stage 3 Pancreatic Adenocarcinoma

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…

A study for adults with previously-treated metastatic pancreatic adenocarcinoma using study drug GVAX

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…

Study of Drug for the Treatment of Pancreatic Cancer

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…

Meditation and Stretching for Post-Treatment Lyme Disease Syndrome

Condition: Infectious Disease / Lyme Disease
Investigator: Brian Fallon, MD
Status: Closed
The CDC estimates that 10-20% of patients with Lyme disease will go on to have chronic symptoms despite having had appropriate treatment, a condition known as Post-Treatment Lyme Disease Syndrome (PTLDS).
