Active clinical trials for "Obesity"

This study looks at how well a new medicine, called semaglutide, works at helping people with obesity and prediabetes. This study will look at how much weight participants lose, and if participants can go from having blood sugar that is higher than normal (prediabetes) to having normal blood sugar. Semaglutide is compared to a "dummy" medicine. The "dummy" medicine looks like semaglutide but has no effect on the body. In addition to taking the medicine, participants will have talks with study staff about healthy food choices, how to be more physically active and what participants can do to lose weight. Participants will either get semaglutide or "dummy" medicine - which treatment they get is decided by chance. Participants are 2 times as likely to get semaglutide as "dummy" medicine. Participants will need to take 1 injection once a week. The study medicine is injected with a thin needle in a skin fold in the stomach, thigh or upper arm. The study will last for about 19 months. Participants have to take the study medicine every week for the first 12 months. The last 7 months participants will not take any medication. Participants will have 14 clinic visits and 1 phone call with the study staff. At 9 of the clinic visits Participants will have blood samples taken. Women cannot take part if pregnant, breast-feeding or plan to become pregnant during the study period.

The purpose of this study is evaluate the safety and effectiveness of bariatric embolization as a minimally-invasive image-guided procedure for morbid obesity. In this procedure, specific blood vessels to the stomach are blocked in order to suppress some of the body's signals for feeling hungry, leading to weight loss. Morbid obesity is currently treated with diet and exercise, medications, and surgery. This study is designed to help treat obesity using a minimally invasive, non-surgical, angiographic (through the blood vessel) approach. This procedure is similar to a common procedure used to treat bleeding within the stomach. This version of the procedure has been named "bariatric embolization". Although there are over 40 hormones that limit food intake, there is only one hormone, ghrelin that has been shown to stimulate (prompt) food intake. In obese patients, eating fails to suppress ghrelin levels, which is believed to prevent feeling full after a meal and to lead to overeating. Due to the strong hunger craving effects of ghrelin, this hormone has been a target for the treatment of obesity and weight loss. More recently, ghrelin has been shown to have a significant role in the long-term effect of weight loss in bariatric (obesity) surgery where ghrelin levels are shown to be much lower when compared to untreated patients. Recent data collected in animals in has shown that blocking blood vessels to a particular portion of the stomach (bariatric embolization) can temporarily decrease levels of the appetite inducing hormone ghrelin, and decrease short-term weight gain. In a study of 5 people, there was a decrease in ghrelin levels and weight loss in the first month after the procedure, but there is no information about the effects of the procedure over longer periods of time. The investigator hopes to learn if bariatric embolization results in safe and effective weight loss in people who are morbidly obese.

This research is planned to build a basis about the effect of acupuncture on serum metabolic parameters in pre-menopausal obese women with economic evaluation.

Our overall goal is to determine the effect of Phentermine and Topiramate ER on gastric emptying, gastric accommodation, satiety, and satiation in obese participants.

The global obesity epidemic presents an unprecedented challenge to the public health worldwide. The factors associated with obesity are complex, and include health behaviors, such as eating habits and daily physical activity, and broader social, environmental and biological determinants that influence these health behaviors. The intestinal microbiota has several beneficial functions related to host health and accumulating evidence indicates that the gut microbiota plays a significant role in the development of obesity, obesity-associated inflammation and insulin resistance. Experimental studies reveal a shift in the abundance of Bacteroidetes and Firmicutes. Presumably, obesity affects the diversity of the gut microbiota and, probably, the way individuals harvest energy from nutrients. Differences in community composition, functional genes and metabolic activities of the gut microbiota appear to distinguish lean vs obese individuals, suggesting that gut 'dysbiosis' contributes to the development of obesity and/or its complications. Recent studies have suggested some beneficial effects of probiotics and/or prebiotics on obesity and metabolic syndrome in adults; such experience is limited in children and adolescents. The aim of this study was to evaluate potential effects of add-on probiotics to standard therapy on anthropometric measurements, lipid profile and oxidative stress parameters in children.

This study is the first administration of GSK2890457 in humans. The study will be conducted in 3 parts: - Part A (conducted at a single investigative site) will determine the safety and tolerability of GSK2890457 alone in healthy subjects during six weeks of dosing, as well as evaluating the potential for a pharmacokinetic interaction with metformin. Part A consists of Screening, Treatment (6 weeks) and Follow-up periods. - Part B (conducted at multiple sites) will determine safety, tolerability, and pharmacodynamics (PD) in subjects with Type 2 diabetes (T2D) when co-dosed for six weeks with liraglutide (Victoza). Part B consists of Screening, Run-in (1 week), Stabilization (12 weeks), Treatment (6 weeks) and Follow-up periods. - Part C (conducted at multiple sites) will determine safety, tolerability, and PD in subjects with T2D when co-dosed for 6 weeks with metformin. Part C consists of Screening, Run-in (1 week), Stabilization (12 weeks), Treatment (6 weeks) and Follow-up periods.

The purpose of this study is to evaluate the impact of minor variations in Incisionless Operating Platform (IOP)procedural techniques on gastric emptying, hormone levels, satiety, and weight loss in the treatment of primary obesity. It will confirm, in an open prospective study, the action mechanisms for the "POSE" endoscopic treatment technique for obesity, and it will help determine if they are maintained at least 6 months following the procedure. Durability of weight loss will be tracked through post-POSE visits up to 18 months following the procedure.

This study is to determine if the Lap-band system is safe and effective for use in morbidly obese adolescents.

The investigators hypothesize that Metformin decreases weight, normalizes lipid profile and increases insulin sensitivity; the study team hope to get better effect of weight decrease and metabolic processes repair in the intensive treatment group with intervention of physical activity, diet correction and Metformin use.

This study is designed to verify that web based follow up intervention after a classic multidisciplinary face-to-face obesity treatment will reinforced nutrition and exercise self-efficacy, improve drop out rate and advance sustainability after weight loss of obese women. Research Questions and Hypotheses How does a web based follow up intervention change self-efficacy of women participating in an obesity intervention? How does a web based follow up intervention affect the drop out rate of women participating in an obesity intervention? How does a web based follow up intervention influence sustainability of women participating in an obesity intervention?
