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…
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…
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…
The Columbia Otolaryngology Department is interested in understanding the intersection of vaping, smell, and taste and their impact on individuals' preferences for certain flavors. Participation will involve answering a series of questionnaires in addition to completing a formal evaluation of your smell and taste with standardized measurements. You can…
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 use of electronic cigarettes, also known as e-cigs or vaping, has increased among former smokers and young adults who have never smoked. Relatively little is known, however, about their health effects (whether they are adverse, have no effect, or are beneficial). The purpose of this research study is to evaluate (1) the association of e-cig use with…
The purpose of the study is to determine if the drug, CAEL-101 in combination with plasma cell treatment improves overall survival for patients who are diagnosed with stage 3b of AL amyloidosis. Patients who participate in this study will receive CAEL-101 as well as plasma cell treatment or Placebo as well as plasma cell treatment to compare the effects.
The purpose of the study is to determine if the drug, CAEL-101 in combination with plasma cell treatment improves overall survival for patients who are diagnosed with stage 3a of amyloid light chain (AL) amyloidosis. Patients who participate in this study will receive CAEL-101 as well as plasma cell treatment or Placebo as well as plasma cell treatment to…
This is a four-session study in which we will be recruiting existing cigarette smokers to explore the competitive dynamics between memory encoding and memory retrieval. To participate, you will first go through a phone screening to determine eligibility and learn about the study. Then you will be asked to visit our facility at the Morningside Campus of…
The purpose of this study is to evaluate the safety and effectiveness of an antibody drug (STI-6129) in patients with AL amyloidosis that has returned or has not responded to treatment (relapsed/refractory). The study drug (STI-6129) will be given in 3 injections through a needle, into a vein as an intravenous (IV), with 21 days between each injection.
HELIOS-A is a global Phase 3 randomized, open-label study designed to evaluate the safety and efficacy of ALN-TTRSC02 in adult patients with hATTR amyloidosis experiencing neurologic symptoms brought on by the disease. The study will also evaluate any changes in quality of life experienced by study participants. ALN-TTRSC02 utilizes the mechanism of RNA…
This is a research study for subjects that have been previously treated for systemic light chain (AL)amyloidosis (a disease in which abnormal protein deposits can damage organs and tissues in your body) and nowrequire further treatment. The main purpose of this study is to evaluate the safety and determine the maximum tolerated dose of aninvestigational new…
The purpose of this study is to test for any good and bad effects of the study drug called isatuximab. Isatuximab may or may not improve your AL amyloidosis, but it could also cause side effects. Isatuximab is not approved by the Food and Drug Administration (FDA). Isatuximab has been shown to have good effects in some patients with recurring multiple…
The study is being done to see if the combination of bendamustine and dexamethasone will help people with amyloidosis that has returned after standard treatment. Bendamustine is currently approved by the Food and Drug Administration (FDA) for treatment of chronic lymphocytic leukemia (CLL) and is under clinical development in the United States for the…
The purpose of this study is to see if daratumumab when given with three other drugs cyclophosphamide, bortezomib (VELCADE) and dexamethasone is useful for treating patients with Amyloid light chain Amyloidosis (also known as AL Amyloidosis). The study will look at what happens (both good and bad) when daratumumab is given with these three drugs compared to…
The purpose of this study is to evaluate the efficacy and safety of ION-682884 given for 24 months in patients with hereditary transthyretin-mediated amyloid polyneuropathy (hATTR-PN) also known as Familial Amyloid Polyneuropathy (FAP), and determine if it can help people with mild or moderate polyneuropathy. To be in this study you must have FAP and be…
The purpose of this study is to evaluate whether study drug NEOD001 will improve survival in subjects with AL amyloidosis and/or increase the interval of time that they can go without requiring hospitalization for problems with their hearts. This study will also evaluate whether NEOD001 improves the function of subjects' organs that have been affected…
The purpose of this study is to find out if MLN9708 plus dexamethasone improves against systemic light chain amyloidosis better than the physicians choice chemotherapy treatment.
