NCT04963231
The purpose of this study was to evaluate the safety and efficacy of once daily subcutaneous (SC) administration of setmelanotide in participants with obesity and specific gene variants in the MC4R pathway.
NCT05748158
The goal of this clinical trial is to determine the physiological basis for the differences in weight regain among adults (25-59 years old) with obesity following participation in a behavioral weight loss program. Eligible participants will undergo a baseline evaluation after which they will enter an up to 20 week behavioral weight loss program with the goal of losing at least 7 percent of their baseline weight within 35 weeks. Participants who meet the weight loss goal will be asked to remain weight stable for 2 weeks after which they will undergo a clinical examination. They will then be observed for 1 year during which they will undergo 2 additional clinical examinations, one 4 months after completing the weight loss program, and the other 12 months after completing the weight loss program.
NCT03651765
This was a long-term extension trial to study the safety and tolerability of continued setmelanotide treatment in participants who had completed a previous clinical trial on treatment with setmelanotide for obesity associated with genetic defects upstream of the Melanocortin-4 (MC4) receptor in the leptin-melanocortin pathway.
NCT06579079

NCT06745570
This study is being performed to understand the effects of a lifestyle modification and sleep intervention on weight loss outcomes in adolescence. The main question the study aims to answer is: \- What are the initial effects of a lifestyle modification and sleep intervention, including effects on weight, eating behaviors and dietary intake, and sleep? Participants will: * Participate in remote, group-based, weekly weight loss and sleep coaching for 16 weeks. * Complete study assessments at baseline (pre-intervention), mid-intervention, and post-intervention. * Complete daily sleep diaries for three 7-day periods at each assessment point.
NCT02920671
Investigators are recruiting adults (men and women, ages 18 to 65 years, inclusive) with a confirmed genetic diagnosis of mitochondrial disease. Investigators are also recruiting both obese and normal-weight healthy volunteers (men and women, ages 18 to 65 years, inclusive) without a family history of mitochondrial disease to compare to affected individuals. The study involves non-invasive MRI methods and glucose tests to focus on the relationship between mitochondrial disease, obesity, and the risk of diabetes. All study visit procedures will be completed within 2 days, which includes an overnight stay at the Hospital of the University of Pennsylvania. There are no study medications or sedations, and participants will be continually monitored during minimally-invasive procedures (e.g., blood draws). All participants will be able to receive compensation. Furthermore, it may be possible to provide reimbursement for travel, lodging, and meals for individuals with mitochondrial disease. Investigators hope that this research will contribute to the current knowledge of mitochondrial disease and that it will improve diagnostic and treatment approaches.
NCT03710746
This project seeks to improve the effectiveness of a novel dissonance-based obesity prevention program that has reduced future BMI gain and overweight/obesity onset by (a) experimentally testing whether implementing it in single- versus mixed-sex groups, which should increase dissonance-induction that contributes to weight gain prevention effects, and (b) experimentally testing whether adding food response and attention training, which theoretically reduces valuation of and attention for high-calorie foods, increases weight gain prevention effects. This randomized trial would be the first to experimentally manipulate these two factors in an effort to produce superior weight gain prevention effects. A brief effective obesity prevention program that can be easily, inexpensively, and broadly implemented to late adolescents at risk for excess weight gain, as has been the case with another dissonance-based prevention program, could markedly reduce the prevalence of obesity and associated morbidity and mortality.
NCT04847557
The main purpose of this study is to assess the efficacy and safety of Tirzepatide (LY3298176) in participants with heart failure with preserved ejection fraction and obesity.
NCT03751137
Childhood obesity is increasing with more than one-third of adolescents currently overweight and one in five with obesity. The lifelong incidence of obesity-related morbidities is also increasing with childhood obesity. It is not yet known how obesity develops in an individual, specifically in early childhood. Further, it is unclear what mechanistic role a child's earliest nutrition or changing intestinal flora has in the etiology of obesity. Very young children are developing appetite and satiety patterns early in life. Nutrition and gut microbial flora have impact on how these processes unfold, but specific mechanisms are not yet well understood. The investigators hypothesize that formula-fed infants with changes in their microbial flora are more likely to have altered carbohydrate metabolism, evidenced by greater imbalances of fatty acid production, and are more likely to have accelerated growth trajectory due to satiety disruption. The investigators further hypothesize that altered carbohydrate metabolism, e.g. imbalances of short- and long-chain fatty acid levels in the gut, stimulate cellular stress and affect specific gut hormones. This study will compare the microbiome of the intestinal microbial flora in two groups of infants, one breast fed and the other formula fed, using longitudinally collected fecal samples from both groups. Samples will be subjected to shotgun metagenomic analysis and simultaneous metabolomic analysis. A bioinformatics approach will elucidate key differences among and between sample groups, and will further analyze bacterial gene expression levels related to carbohydrate metabolism. This study will compare the expression of human proteins involved in cellular stress response and gut peptide signaling by applying quantitative Reverse Transcriptase-Polymerase Chain Reaction to human messenger RNA isolated from the longitudinally collected samples from both groups. Finally, this study will monitor the trajectory of growth and feeding over the first 2 years of life. The project's focus on the influence of different early feeding types, microbial flora changes, and altered carbohydrate metabolism leading to disruption of gut-brain signaling will provide critical data for host:microbiome interactions and translational therapeutic targets.
NCT05882045
The main purpose of this study is to evaluate the efficacy and safety of retatrutide once weekly in participants with obesity and established cardiovascular disease (CVD). The study will last about 113 weeks.
NCT05086302
A prospective, Multicenter open-label post approval trial for adults with a Body Mass Index (BMI) of 35.0-40.0 kg/m2 or a BMI of 30.0 to 34.9 kg/m2 with one or more major obesity-related comorbid conditions who have failed to achieve and maintain weight-loss with a supervised weight control program. The study aims to demonstrate that the safety of the device in the post market setting is comparable to what was observed in the US pivotal study.
NCT06867718
This is a phase 2, 36-week randomized, double-blind, placebo-controlled, parallel arm study that will evaluate the safety, tolerability, weight loss efficacy, pharmacodynamic effects, and pharmacokinetics of RGT001-075 in adults who are obese (BMI ≥30 kg/m²) or who are overweight (BMI ≥27 kg/m²) with at least one weight-related comorbidity. RGT001-075 or matching placebo will be administered once daily.

The study will evaluate weight management in participants with obesity (BMI ≥30 kg/m2) or who are overweight (BMI ≥27 kg/m2) with weight-related comorbidities (excluding type 2 diabetes mellitus).
NCT04907396
The IWCR is a global scientific study aimed at better understanding the opportunities and barriers for reducing the prevalence of obesity by collecting information from people who have experience with weight management in their everyday lives. The investigators seek to gather information on a wide range of weight management experiences, ranging from weight loss and weight loss maintenance to weight gain and inability to lose weight.
NCT02991534
Cardiovascular (CV) disease is the number one cause of death in American women, and all adult women are potentially at risk for CV disease. There are clear gender differences in the control of CV risk factors such as lipids, blood pressure, and intermediate diabetes outcomes nationally and within the VA, with women Veterans often at higher CV risk than their male counterparts. The combination of disparities and gender-specific CV risk factors suggest an urgent need for CV risk factor management in women Veterans. As one project in the Enhancing Mental and Physical health of Women through Engagement and Retention (EMPOWER) QUERI, the objectives of "Facilitating Cardiovascular Risk Screening and Risk Reduction in Women Veterans" are to implement and evaluate a CV risk reduction toolkit (CV toolkit) designed to increase identification of CV risk among Women Veterans, enhance patient/provider communication about their risk, and increase Women Veterans' engagement and retention in relevant health services including referrals to key health programs (e.g., MOVE!, dieticians, health coaches, and CV specialists as needed). The initial CV Toolkit includes four components: (1) Patient education/activation tools including educational materials and a patient CV self-screener to help make CV risk discussion a priority for women before they enter the exam room; (2) A CV risk assessment computerized template to systematically capture CV disease risk factor history and data from the medical record and then facilitate referrals to Gateway to Healthy Living program and other CV risk reduction services/programs; (3) Provider information and education programs as well as referral tools to internal services; and (4) The Gateway to Healthy Living, a facilitated goal-setting group tailored for women Veterans. The goal is to implement the CV Toolkit at four VA facilities with comprehensive women's health clinics. The implementation of the CV Toolkit will be evaluated using a non-randomized stepped wedge design and will apply the evidence-based Replicating Effective Programs (REP) implementation strategy. For the nonrandomized stepped wedge design, each phase represents when one site moved from inactive to active implementation. It was pre-specified for the non-randomized design to evaluate the outcomes as the odds ratio of active intervention versus inactive for the overall study period and not by individual site/phase. This is a function of the use of the non-randomized design. Since the order of sites being introduced into the active intervention is not random, probabilistically the individual site results are not as meaningful here as they would be in a randomized stepped wedge design. Also, mixed methods implementation evaluations will focus on investigating primary implementation outcomes of adoption, acceptability, feasibility, and reach. Multilevel stakeholder engagement will be prioritized. Program-wide organizational-, provider-, and patient-level measures and tools will be utilized to enhance synergy, productivity, impact and facilitate spread.
NCT05412004
The purpose of this study is to evaluate the effect and safety of tirzepatide in participants with moderate to severe obstructive sleep apnea and obesity who are both unwilling or unable to use Positive Airway Pressure (PAP) therapy in GPI1 and those who are and plan to stay on PAP therapy in GPI2.
