This study is being done to see how safe an investigational drug is and how well it will work to help people with obesity, or overweight with weight-related conditions like hypertension, dyslipidemia, obstructive sleep apnea, non-alcoholic fatty liver disease, or diabetes. If you qualify to be in the study, you will be given frequent lifestyle and behavioral counseling for the first 12 weeks of the study. The counseling will consist of advice on physical activities and dietary advice on healthy eating. During the treatment period, you will receive either tirzepatide or placebo. Placebo is a solution that looks like the study drug but has no medicine. The chance that you will get the study drug is 2 in 3. This phase will last about 72 weeks.

Topiramate is a commonly prescribed medication at weight management clinics. While doctors know that some people respond better to topiramate in terms of weight loss and changes in eating behaviors, the reasons WHY some respond better than others are not known. Knowing more about the relationships between topiramate doses, concentrations of topiramate in the blood stream, and an individual’s response to this medicine will help doctors determine those who may be more likely to benefit. Doctors also want to know if someone’s genes (their DNA) may help explain why some people respond better to topiramate than others. We expect that you will be in this research study for about 14 weeks (3.5 months).

In this study we want to find out more about weight loss and how diet and medications can affect weight loss. This study will last for up to 58 weeks. There are two phases to the study: - A weight loss phase with prescribe meals that lasts 6 weeks. - A study medication/placebo phase that lasts up 52 weeks. You will not know if you are receiving the medication or the placebo.

To assess the safety of Afrezza in a pediatric population when compared to the usual standard of care insulin.

This is a study designed to evaluate the safety, tolerability, and efficacy of a one-time gene therapy (BBP-631) for adult patients diagnosed with classic congenital adrenal hyperplasia (CAH). The goal of gene therapy for CAH is to give the body a functioning CYP21A2 gene using a vector (an agent used to deliver a gene into the body). Having a functioning CYP21A2 gene in the adrenal gland may allow the body to naturally produce its own cortisol and aldosterone. The study treatment and follow-up lasts 1 year with a long-term follow-up of 4 more years.

Black Americans are 60% more likely to be diagnosed with Type 2 Diabetes (T2D) and 2 times more likely to die from T2D than non-Hispanic White Americans. Recent research has shown that sedentary behavior (such as sitting or lying down) have a significant negative impact on health. We are doing a small study with older people who identify as Black or African American and have T2D to look at ways to reduce sedentary behavior. The study will last about 1-2 months for each participant.

The purpose of this study is to implement an intervention using a Follower, Action plan, and remote Monitoring (FAM) of glucose data to reduce severe hyperglycemia in adults with Type 1 Diabetes Mellitus at risk for diabetic ketoacidosis. You and your chosen “follower” (family member, caregiver, or friend) will be asked to attend 6 visits (in- person or remote) as a pair (“dyad”) with the study team that will last up to 30 minutes to 2 hours each across a span of 4 months.

TrialNet is an international research group dedicated to the study, prevention, and early treatment of Type 1 diabetes. Type 1 diabetes is now understood as a disease that develops over time in stages. Stage 1 starts with the appearance of having two or more autoantibodies. This is followed by Stage 2, which is the development of abnormal blood glucose levels. Stage 3 is the clinical diagnosis of Type 1 diabetes. This study will help us learn more about how Type 1 diabetes occurs through the screening of diabetes-related autoantibodies and monitoring individuals who have tested positive for these autoantibodies.

Feasibility study to test our overall hypothesis that time restricted eating (TRE) presents a viable alternative to caloric restriction for improving glycemic measures and reducing weight in overweight/obese patients with metformin-only treated Type 2 diabetes (T2DM).

This study will enroll children aged 6 to 12 years who have difficulty in maintaining a healthy weight and see if the medication Vyvanse may help them to reduce their weight.

The purpose of the study is to compare quality of life (QOL), adherence, insulin resistance, body composition and efficacy of LAGH to DGH in children with GHD.

In this study, we will examine the safety and tolerability of Sodium glucose co-transporter 2 inhibitor (SGLT2i) (generic name: empagliflozin) for patients who are overweight/obese and have been diagnosed with Cystic Fibrosis Related Diabetes (CFRD).

The study drug FP-001 (Leuprolide mesylate) is being developed for children that are suffering from central (gonadotropin-dependent) precocious puberty (CPP). Leuprolide has been approved in the United States (US) and the European Union (EU) as treatment for prostate cancer already, and other forms of Leuprolide from other companies have been approved for the treatment of CPP. In this clinical study, Leuprolide will be used in the form of a 6-month depot injection.

The purpose of the Atherosclerosis Risk in Communities (ARIC) Study - ARIC Generation 2 research study is to evaluate the link between glucose and heart problems in adults with type 2 diabetes. Heart problems can be common in people with type 2 diabetes. We are interested in measuring your blood sugar (glucose) using a continuous glucose monitor and monitoring your heart rhythm at the same time.

This study will compare the effectiveness and durability of intensive behavioral counseling vs. medical management plus low-intensity behavioral counseling on BMI, body fat, cardiometabolic risk factors, and quality of life in adolescents with severe obesity. We hypothesize that Wegovy (semaglutide) plus low-intensity behavioral counseling will elicit superior reductions in BMI and body fat and greater improvement in cardiometabolic factors and quality of life compared to intensive behavioral counseling at 56 weeks.

This is a study of individuals older than 18, undergoing abdominal surgery, and are amenable to fat samples being collected during their surgical procedure, with the option to participate in other tests that can provide information on insulin sensitivity and fat distribution. This study is trying to figure out how fat tissue is related to an individual's health status and health conditions, and the analysis of the aging of cells that make up the human body.

The purpose of this research study is to find out how many people with acute pancreatitis develop diabetes. Risk factors for diabetes and the types of diabetes that occur after acute pancreatitis will also be studied. A small number of people who already had diabetes before their acute pancreatitis attack will be enrolled for comparison. Diabetes is a known complication of acute pancreatitis. Diabetes can last a few weeks after acute pancreatitis and get better. Diabetes may not improve after acute pancreatitis. It can also appear a year or more after acute pancreatitis. Little data is available on diabetes after acute pancreatitis. This study will help us better understand diabetes after acute pancreatitis and who is at increased risk of developing it, as well as the different types of diabetes. We are asking participants to take part in this research study who have recently had an acute pancreatitis attack. Participants may be on this study for up to 5 years. There is a screening/enrollment visit, a metabolic visit and 5 year follow-up period. If you had diabetes before your acute pancreatitis attack, your study participation will end after the enrollment visit. If you did not have diabetes before your acute pancreatitis attack, you will return to the clinic for up to 6 more visits. An additional two visits can be done either at the clinic or by phone. If you are diagnosed with diabetes during the follow-up period, you will be asked to come in for an additional visit.

This study will seek to learn about barriers to management of Type 2 diabetes for children ages 10-17. This study is recruiting children, and their parent/guardian, who are managing with oral medication or insulin.

We are studying hormone levels and fatigue of people who have recently had COVID-19. Participants will complete questionnaires and have blood drawn to determine hormone levels. Participants who are experiencing high levels of fatigue or who have abnormal hormone levels will complete questionnaires and have blood drawn every three months for a year. We are hoping to determine how COVID-19 affects hormone levels and the pituitary gland, which is responsible for releasing hormones.

This is a new type 1 diabetes onset study for ages 12-35 years old. We are looking at JAK inhibitor drugs to see if they can preserve beta cell function.

This study is looking at glucose (blood sugar) patterns in participants with Turner Syndrome between the ages of 3-80 years old. This will be done by obtaining 2 hours frequent blood sampling by completing an Oral Glucose Tolerance Test and a Mixed Meal Tolerance Test. Participants will also wear a continuous glucose monitor for 2 weeks. Along with the OGTT and MMTT, participants are asked to provide a blood sample for DNA and RNA testing. Participant’s parents are asked to provide a saliva sample for DNA testing

Type 2 diabetes (T2D) confers a high risk of cardiovascular disease (CVD), particularly among older adults who tend to be physically inactive. Most studies that have examined the effects of changing sedentary behavior (SB) have focused on young healthy males and prioritized glycemic outcomes. We will look at the effect of 3 different ways of breaking up sitting: 1) 4 hours of prolonged SB, 2) 4 hours of SB broken up by 5 minutes of self-paced walking every hour, and 3) 4 hours of SB with one 20-minute bout of self-paced walking. In addition to examining the overall effects of each condition, differences between men and women will be evaluated.

We are looking at how an 8-week exercise program of walking for 30-45 minutes 3 times/week affects the body. This study is for people who are prediabetic and overweight or obese. We will compare the exercise group to a group that didn’t participate in the exercise to see if there are differences in gut microbes, body measurements, and blood work.

CAH is an inherited genetic disorder that affects the adrenal glands, a pair of walnut-sized organs above the kidneys. The disease affects the production of steroid hormones by the adrenal glands, which include “glucocorticoids” such as cortisol, which regulate your body’s response to illness or stress. People with CAH often have abnormal levels of certain adrenal sex hormones, which can have negative effects on overall health. The purpose of this study is to see if tildacerfont is safe and effective in reducing the level of certain hormones. Tildacerfont will be compared to “placebo”, which is a drug that looks like the investigational drug but does not contain any tildacerfont or any other active compound.

Individuals with type 1 diabetes often develop an impaired awareness of hypoglycemia (IAH), meaning they are not fully aware of having low blood glucose levels. This research study is looking to determine what happens in the brain after repeat episodes of hypoglycemia.

This is a study of individuals older than 18, undergoing abdominal procedures in which the liver is accessible, and are amenable to liver samples being collected during their surgical procedure, with the option to participate in a specialized scan that can provide information on liver health, stiffness, and fat content. This study is trying to figure out how senescent (aging) cells in the liver are related to an individual's health status and better understand the association between these cells and different metabolic diseases.
