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…
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!
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.…
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…
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…
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…
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…
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…
We are recruiting individuals and/or families with members under the age of 65 who have dementia or are experiencing memory problems. Our initial screening can be completed in person or over the phone. The evaluation will take about 1 to 1.5 hours per person and includes a: 1. Blood sample (5 tablespoons) or saliva (1 teaspoon) collection: These blood…
For over 30 years, The Columbia University Alzheimer's Disease Research Center (ADRC) has worked with thousands of participants who have helped provide important insights into how the brain ages and why Alzheimer's disease may develop. We are actively recruiting adults 65 years of age and older who share our commitment to be part of this…
The purpose of this study is to find out if performing Magnetic Resonance Image (MRI) scans of your brain with adaptive planning during your radiation treatment of your high-grade glioma will help determine how sensitive the images collected of the brain are at detecting the response of the tumor to the cancer treatment. In this study, four or seven MRI…
The purpose of the study is to evaluate the safety of Lutathera alone in patients with recurrent glioblastoma and the combination of Lutathera with radiotherapy with temozolomide (TMZ) in patients with newly diagnosed glioblastoma (GB) and to establish the appropriate dose of this combination. Lutathera is a radioligand therapy, which is a targeted…
Children and young adults with diffuse midline glioma will be treated with Focused Ultrasound (FUS) with DEFINITY microbubbles and neuro-navigator-controlled sonication. The overall goal of this study is to see if the study treatment plan will improve the outcome of participants with diffuse midline glioma, for which no known cure exists, and determine…
A significant focus of healthcare research is aimed at biomarker discoveries in brain and heart diseases in particular, and their impact on the human body in general. MRI is a key component in these healthcare services. It provides a non-invasive and non-ionizing approach to diagnose pathologies along with significant internal and external contrast…
This study is of a drug called CT1812, that is being evaluated as a possible treatment for Dementia with Lewy Bodies. In this study, which is carried out at multiple sites in the country, participants receive either CT1812 at one of two doses or placebo. The duration of the study is up to about 35 weeks. Participants receive blood tests, cerebrospinal fluid…
This is a research study for persons with memory problems that examines the utility of performing positron emission tomography (PET) scans for the brain amyloid protein found in Alzheimer's disease.
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…
The purpose of this study is to find the best dose of a drug called MTX110 and a contrast agent called gadolinium that can be given safely in children with newly diagnosed diffuse midline gliomas, which is a kind of brain tumor. All patients enrolled in the study will receive infusion of MTX110 and Gadolinium delivered with a pump directly into the tumor…
Columbia Medical Center is recruiting for a study to test whether the drug oxytocin can improve symptoms of emotion and behavior (e.g. apathy) in people with frontotemporal dementia. The study will last for up to 24 weeks (6 months). This is a crossover study, which means that each participant will receive both oxytocin and placebo (medically inactive…
The purpose of this research study is to test whether the advanced perfusion MRI done prior to starting Bevacizumab and a few weeks after starting Bevacizumab can determine your response to the treatment better than the standard MRI performed at typical time points. The researchers want to see if this type of advanced MRI is better or the same as what is…
This is a 22-week treatment, multicenter, double-blind, placebo-controlled, parallel group, Phase 2 study to evaluate the efficacy, safety, and tolerability of the study drug E2027, in participants with Dementia with Lewy Bodies (DLB) Lewy Body Dementia - LBD. The main purpose of this research study is to find if a new drug called E2027 works in people who…
