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…

Early Age-Related Hearing Loss Investigation (EARHLI)

Condition: Ear, Nose and Throat / Hearing Loss
Investigator: Justin Golub, MD, MS
Status: Currently Recruiting
Early Age-Related Hearing Loss Investigation (EARHLI) is a study to obtain information on how a hearing aid-based intervention can prevent cognitive decline in those at risk for Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD). Age-related hearing loss (ARHL) is the third most common chronic condition in older adults. The…

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.…

Speech Perception in Hearing Impaired Listeners

Condition: Ear, Nose and Throat / Hearing Loss
Investigator: Nima Mesgarani, PhD
Status: Currently Recruiting
The purpose of this study is to learn more about the mechanisms of hearing loss, specifically to learn how abnormalities in the brain may produce certain experiences that are common in patients with hearing loss. Individuals with hearing loss will be compared to individuals with normal hearing.

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…

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…

Brain imaging in bipolar depression to understand the role of inflammation in its treatment.

Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Martin Lan, MD
Status: Closed
This is a research study to understand what causes bipolar disorder and how medications treat bipolar depression. Particularly, we are looking at the importance of inflammation in the process. If you participate, you will receive an experimental medication for your depression named ethyl eicosapentaenoic acid (ethyl EPA), an omega 3 fatty acid. You will…

Research Study offering Treatment for Self-Injury (Bipolar Disorder)

Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Jeffrey Miller, MD
Status: Closed
The goal of this study is to examine how effective and well-tolerated a possible new treatment for individuals who injure themselves frequently will be. All research procedures can be done from home no in-person visits are required. We are studying a minimal-risk form of electrical brain stimulation called transcranial direct current stimulation, or tDCS.…

Brain imaging in bipolar depression to be able to predict who will respond to antidepressant treatment

Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Martin Lan, MD
Status: Closed
We are trying to understand what causes bipolar disorder and how medications treat bipolar depression. If you participate, you will have two different brain scans (MRI and PET scan). You will also have antidepressant treatment for free. We will then be able to see whether information on the brain scans connects with how people do on the medications. The…

A study to Assess Safety and Effectiveness of Study Drug OTO-104 in Patients at Risk of Hearing Loss From Cisplatin Chemotherapy

Condition: Ear, Nose and Throat / Hearing Loss
Investigator: Alice Lee, MD
Status: Closed
Cisplatin is a chemotherapy medicine that is used to treat a variety of cancers. At high total (cumulative) doses it can be associated with progressive and irreversible hearing loss. The purpose of this study is see if injections of OTO-104 can protect against hearing loss associated with cisplatin therapy in the treatment of cancer. OTO-104 contains an…

A study for Adults with Sudden Sensorineural Hearing Loss Using the drug Am-111 to Evaluate its Effectiveness in Restoring Hearing Loss

Condition: Ear, Nose and Throat / Hearing Loss
Investigator: Anil Lalwani, MD
Status: Closed
Acute inner ear hearing loss is the sudden onset of hearing loss, usually in one ear, without any known cause. Acute hearing loss can permanently destroy some of the hair cells (that govern the sense of hearing) and / or hearing nerve in the inner ear.The drug AM-111 has been developed to protect the hearing cells and nerve following sudden inner ear…

MRI Effects of D-cycloserine & Lurasidone in Bipolar Depression

Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Joshua Kantrowitz, Md
Status: Closed
We will evaluate the D-cycloserine (DCS) and lurasidone with MRI measurement of brain responses to DCS. DCS is a drug that works on the same brain receptor as ketamine. DCS is not approved by the FDA for bipolar depression. Study participants will receive a dose of lurasidone or placebo in one MRI and a dose of DCS in another, followed by an optional follow…

A Study of the Gene Therapy CGF166 in Patients with Severe-to-Profound Hearing Loss

Condition: Ear, Nose and Throat / Hearing Loss
Investigator: Lawrence Lustig, MD
Status: Closed
The purpose of this research is to find out whether it is safe to use a virus to deliver a new gene to the inner ear of people with hearing loss. This is a kind of gene therapy which involves gene transfer. Once the genetic material and vector are surgically administered to you, it is not possible to remove these agents. The study is designed to evaluate…
