Active clinical trials for "Weight Loss"

Introduction: GLP-1 receptor agonists (aGLP1) act increasing pancreatic insulin secretion in response to the glucose, they reduce glucagon secretion and reduce appetite by acting in the central level. Several aGLP1 were approved through different clinical trials where they showed efficacy in the glycemic control and reduction in cardiovascular events. They also showed weight loss in different clinical trials with patients with diabetes mellitus 2 (DM2) and also in specific clinical trial where the weight loss was the primary endpoint (STEP study). Objective: The objective is to evaluate and compare the weight loss in patients with DM2 treated with the different aGLP1 for the first time. Secondary endpoints are HbA1c reduction, changes in quality of life and physical activity and the safety of these drugs. Design: It is a postauthorization, multicenter, non-randomized and prospective study. Patients that will start treatment for the first time with aGLP1 will be recruited in 10 primary care centers in SERGAS Galician Hospitals for a period of 6 months and 44 weeks of follow-up. The primary endpoint will be to evaluate the wight loss with the different aGLP1 and the secondary endpoint will be HbA1c reduction, changes in the quality of life through the EuroQol-5D and changes physical activity through the SF-12 questionnaire, and also the safety of these drugs. The sample size will be of 360 patients. Statistical analysis: Previous studies showed efficacy in weight loss with semaglutide about (3,6-4,9 kg), while with other aGLP1 the weight loss was smaller , about (0,86-2,96 kg). Based in these data and with a 5% of significance level, a weight loss average in the aGLP1 group of 2,5 kg, average in semaglutide group of 4,2 kg, and combination deviation of 3,0kg, including 360 subjects we will have a statistical power above 90% to detect differences through T-test for independent samples. The justification of this simple size was performed with the statistical software SPSS 3.0 Conclusions: The SEVERAL study will try to provide information about weight loss efficacy, changes in quality of life, physical activity and safety of the aGLP1in patients with DM2 that start treatment with these drugs in the real life (Real-World Evidence)

To study the effects of transcranial direct current stimulation (tDCS) on weight and appetite.

The purpose of this study is to determine the efficacy of combining open-label extended release bupropion (flexible dosing up to 450mg target) and naltrexone (37.5mg) versus Bupropion and placebo along with a daily 500 calorie reduction diet recommendation for weight and health risk reduction in 40 overweight/obese individuals with schizophrenia.

Determine the effects of an 8-week weight loss intervention.

Purpose: The purpose of this study is to test new pharmacologic strategies for weight loss in patients with schizophrenia, a population for which no current weight-loss treatments have gained widespread use. The goal is to recruit overweight people with schizophrenia to participate in a 52-week double-blind, randomized study to assess the efficacy and safety of lorcaserin/metformin combination treatment, lorcaserin monotherapy, and placebo on weight, body composition, and measures of glucose and lipid metabolism. Participants: Approximately 110 subjects will be enrolled at four clinical sites (UNC Chapel Hill, Carolina Behavioral Care, Columbia University, and Augusta University) Procedures (methods): Behavioral: All participants will be offered a behavioral intervention of weekly diet and exercise counseling aimed at modifying cardiovascular risk factors. This intervention will be provided at all in-person study visits after the Baseline Visit and supplemented with weekly interim phone calls to reinforce lessons between visits. Pharmacological Intervention: All participants who meet entry criteria will be randomized to one of the three treatment groups (lorcaserin/metformin, lorcaserin, and placebo).

Despite widespread efforts to improve the treatment of obesity, only limited progress has been made. Calorie restriction (CR) has consistently been shown to produce weight loss, as well as delay the onset of age-related diseases, in numerous species. Most overweight individuals, however, are unable to sustain CR induced weight losses, possibly due to internal feedback systems that signal the body to increase food intake or decrease energy expenditure in response to weight loss. Novel treatment approaches are thus urgently needed that can assist overweight individuals in adhering to a CR regimen over the long-term. Botanicals represent an important and underexplored source of potential new therapies that may facilitate CR. In particular, one promising botanical that may reduce food intake and body weight by affecting neuroendocrine pathways related to satiety is Garcinia Cambogia (Garcinia Cambogia Desr.)-derived (-)-hydroxycitric acid. This compound has been found to facilitate weight loss in a number of studies. To date, few studies have directly tested the effect that this botanical on food intake in humans, its mechanism of action, or its effect on oxidative stress levels; thus rigorous scientific studies on this compounds need to be conducted. A double-blind, placebo-controlled crossover study will be conducted to explore the role that two different doses of this botanical compound have on food intake, satiety, weight loss, and oxidative stress levels. It is hypothesized that compared to placebo, both doses of Garcinia Cambogia (hydroxycitric acid) will reduce food intake, increase satiety, decrease weight, and reduce oxidative stress levels.

The purpose of this study is to compare the safety and effect of HPP404 versus placebo on body weight in overweight or obese subjects.

PROTOCOL SUMMARY Type of Study: Pilot, randomized and single center trial Test Procedure: Omentectomy Aim 1. Determine the effect of omentectomy on 1) insulin sensitivity, 2) beta cell function and 3) plasma markers of inflammation We hypothesize that removal of omental fat increases insulin sensitivity and pancreatic sensitivity to glucose, and decreases systemic inflammation. Aim 2. Identify genes and proteins in adipocytes from obese patients that affect clinical presentation versus those that are affected by obesity for future study. We hypothesize that the genetic samples will help us to identify genes and proteins in adipocytes from obese patients that affect clinical presentation versus those that are affected by obesity and help us to design future obesity genetic studies. Total Enrollment Number: 30 patients who are scheduled to undergo bariatric surgery for weight loss at New York University Medical Center will be invited to participate in this study. Subjects will be randomly assigned, by using a computer-generated randomization scheme, in a single-blind fashion to either the omentectomy (n=15) or control group (n=15).

The purpose of this study is to determine whether Betamarc is effective in improving the appetite and reversing weight loss in patients with advanced Non-Small Cell Lung Cancer.

Overweight and obesity has been associated with a number of adverse pregnancy outcomes in women of reproductive age, including infertility and early pregnancy loss. Recent data suggests that overweight and obese patients are also at increased risk of recurrent pregnancy loss (RPL), a devastating condition that affects 1% of the fertile population. The investigators propose a prospective, randomized controlled trial in which overweight and obese patients with unexplained recurrent pregnancy loss are enrolled in a structured, 6 month, weight loss program or provided routine counseling regarding the importance of weight loss. Pregnancy outcomes will then be followed to assess miscarriage rates. Metabolic outcomes, such as lipid and glucose profiles, will also be evaluated.
