Bariatric surgery and a once-weekly glucagon-like peptide-1 medicine both cause major weight loss in teens, but their effects on mouth and gut bacteria and on damaged blood fats tied to metabolism are still unknown. This study will collect saliva, stool, and routine blood samples from adolescents before treatment and six months later to see how these…

To be in this study you must have DPN and be 18 through 80 years of age, inclusive, with presence of bilateral pain in lower extremities due to DPN for at least 1 year.
This is a Phase 3, randomized, double blind, study evaluating efficacy and safety of riliprubart versus intravenous immunoglobulin (IVIg) in participants with chronic inflammatory demyelinating polyneuropathy. Overall the study will last about 109 weeks (2 years). Participants must be 18 years old at the time of signing the informed consent form.
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!
This program provides family members of individuals with familial ALS the opportunity to contribute to research focused on learning more about why motor neuron degeneration begins and how or why it progresses. This study provides genetic counseling and testing to help participants understand and manage their risk and determine if they want to learn their…
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…
The purpose of this research is to study whether Discogen's non-invasive, low-intensity pulsed ultrasound treatment can help reduce pain for people with leg pain and low back pain. Eligible participants will be randomized into either a Discogen treatment group or a sham control group. All participants will be asked to come to the Columbia University…
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…
Columbia University is currently enrolling in an Ataluren Study from PTC Therapeutics, called PTC-041. We are looking for 5 year old boys, ambulating, confirmed nonsense mutation DMD and on steroids for at least 12 months. If you would like more information about this please reach out to Ameneh Onativia, Columbia Sr. Clinical Research Coordinator II at 212…
The purpose of this study is to Assess Treatments for Painful Diabetic Peripheral Neuropathy (PDPN). To be in this study you must have type II Diabetes Mellitus, PDPN, must be 18 years of age or older, and be able to stop taking some of your current pain medications including pills, creams, patches, marijuana, cannabidiol (CBD) oil, etc. Acetaminophen (…
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 out how doctors describe hepatic encephalopathy episodes in patients medical records in the course of their regular practice. The aim of the study is simply to collect information from their medical records about how their episodes of overt hepatic encephalopathy are described. There is nothing that will be required of…
This study is designed to test how well an intravenous human immunoglobulin concentrate, IGIV-C (compared with placebo) improves your muscle weakness associated with MG symptoms. A placebo is a medication that looks like the study medication but has no active ingredient. Immunoglobulin is an antibody produced by white blood cells that is used by the immune…
The purpose of this study is to compare the time to onset of an episode of overt HE, in subjects with previously demonstrated overt HE after treatment with rifaximin 550 mg BID and lactulose, or rifaximin 550 mg BID. Subjects will be screened to confirm eligibility into the study. Once confirmed, subjects will begin the treatment phase and will be randomly…
This study is designed to test how well an intravenous human immunoglobulin concentrate, IGIV-C (compared with placebo) improves the ability to taper participant's dose of corticosteroids without causing significant increase in your muscle weakness and worsening MG symptoms. A placebo is a medication that looks like the study medication but has no…
The purpose of this study is to look for abnormal genes and gene expression profiles that help determine why a person develops amyotrophic lateral sclerosis (ALS) and related motor neuron diseases (MND) and why their symptoms present and progress with a particular pattern. For up to three years, subjects will be followed every 3 months at the Columbia ALS…
Small fiber neuropathy is a painful condition caused by damage to the small nerves in your arms andlegs. This damage causes burning, sharp-stabbing and aching pain, amongst other types of pain. It can be sometimes difficult to know the cause of the damage to the small nerves in your arms and legs. In most cases, treatment for small fiber neuropathy is…
The purpose of this research study is to test an investigational drug called NP001. The study will evaluate if NP001 has an effect on slowing the signs and symptoms of your ALS, if there are any side effects, and if there are any medical problems with giving the drug as a solution into your vein (intravenous IV administration). An investigational drug is…
