Active clinical trials for "Obesity"

This study has 2 parts: First part is the main study and second part is the extension study. During the main study participants will receive 1 of 4 study medicines. If participants continue in the extension study, they will not receive any study medicine during the extension. The main study will look at how well CagriSema helps participants with excess body weight lose weight compared to a "dummy" medicine and 2 other medicines, cagrilintide and semaglutide. Participants will either get CagriSema, cagrilintide,semaglutide or "dummy" medicine. Which treatment participants get is decided by chance. They will take one injection once a week. The study medicine is injected briefly with a thin needle, typically in the stomach, thighs or upper arms. Extension study: After the main study, not all participants will continue in the extension study. The study staff will tell the participant if they will continue or not into the extension study. In the extension study we will look at what happens to the participant's body weight and diseases related to excess body weight after the participant stops taking the study medicine. The main study will last for about 1½ years and the extension study will last for another 2 years.

This study will look how well semaglutide tablets taken once daily helps people with body weight above the healthy range. Participants will either get semaglutide 25 milligram (mg) once daily or placebo once daily. This study will last for 72 weeks, which includes 1-week screening period, 64 weeks of treatment period and 7 weeks of follow up period.

RYSE is a Family-based Approach for Healthy Lifestyles that is a program for families with children between the ages of 5-12 years old to help them make healthy lifestyle changes to reach a healthier weight. The research program does this with children and their families through guidance about healthy eating, physical activity, and behavior change. The program focuses on helping participating families set up healthy support systems at home, at school and in social settings.

This study will evaluate the efficacy and safety of ALT-801 once-weekly versus placebo as an adjunct to a reduced-calorie diet and increased physical activity in patients with obesity/overweight.

Despite standardized intervention strategies, weight loss and weight loss maintenance largely differ from person to person. Factors which may contribute to these individual differences is current object of research. In order to investigate predictors and barriers for weight management and to investigate two different dietary interventions and two different digital tools for weight maintenance, the LION-Study was designed as follows: Step I (screening, baseline phenotyping), step II (weight loss intervention with formula diet), step III (weight maintenance intervention with 4 intervention groups: low carb/newsletter; low carb/app; low fat/newsletter; low fat/app) and step IV (follow-up). Participants are required to attend visits at seven time points. At screening (month 0) a telephone-based screening interview takes place, in order to test eligibility of the potential participant. If the person is eligible, two consecutive baseline face-to-face visits are planned during step I. After completion of the eight weeks weight loss intervention (month 3), an additional visit takes place followed by three consecutive visits in the weight maintenance step (month 6, 9 and 15). The study ends with a final visit after the follow-up (month 27). Additional contacts (face-to-face and telephone) take place during the weight loss intervention step. Participants will regularly receive a bag with the required formula diet meals. During these "pick up" appointments, the study team actively get in face-to-face contact with participants. At the different visits, data are collected by questionnaires, medical investigations (e.g. MRI, motor function, resting metabolic rate), blood withdrawal as well as urine, feces and saliva sampling. Primary objective is to evaluate the effect of two diets (low carb/low fat) and two digital tools (app/newsletter) on long-term weight loss maintenance 12 months after weight loss. Secondary objective is to identify genetic, epigenetic, physiological, psychological and lifestyle factors that predict the success of weight loss and weight loss maintenance.

The study was designed to test the following hypotheses: Main Objective: To compare the level of spontaneous physical activity at 3 months after re-entrainment by multi-site electrical stimulation (m-ES), measured by actigraphy over 7 days, compared to conventional care (lifestyle and dietary advice and placebo (simulated) electrostimulation) (control arm). Secondary Objectives: To compare the metabolic, inflammatory, cardiovascular and functional parameters, physical activity, quality of life and quality of sleep, at 3 months and at 2 years in the two groups. Design: We will conduct a multicenter controlled study vs. reference care with randomization into two parallel groups and double-blind (placebo electrostimulation). Patients will have the ES material available at home and will be supervised by monthly visits over 3 months and by telephone follow-up for two years. The study size calculation is based on physical activity, the percentage of lean body mass and arterial stiffness measured in the OBEX study. This project will determine whether the training strategy is effective for increasing physical activity and/or in inducing significant metabolic and cardiovascular effects in these patients after 2 years. In addition, it provides a solid base of investigation for the study of the interactions between muscle contraction and cardio-metabolic health with greater precision.

Severe childhood obesity is associated with both immediate and chronic health problems and a severe impact on psychosocial development. Medical and behavioural interventions rarely result in the significant, durable weight loss necessary to improve health outcomes. This is a randomised clinical trial where 50 adolescents, 13-16 years of age, will be randomised to either early bariatric surgery (Roux-en-Y gastric bypass) or intense conservative treatment and possibly surgery after two years of non-surgical treatment or as they have become 18 years.

One possible angle for treating obesity could be slowing down the gastric emptying time. By prolonging the gastric emptying time, the person would ideally experience increased sensation of satiety, and in the long run reduce food intake. If such a treatment provides a clinically significant weight loss, this could be an alternative for surgical procedures, avoiding the risk for perioperative complications as well as complications in the long run. There are now several pilot studies documenting that intragastric treatment with botulinum toxin A (BTA) can be effective, although the treatment perspective is short and do not include repeated injections. However, they demonstrate that BTA-injections are safe for the patient. The treatment is administered by endoscopy.

The primary aim of this study is to is to determine if intermittent fasting (IMF) is an effective dietary strategy for treatment of obesity. A 1 year randomized trial will be used to compare weight loss generated by IMF versus Daily Caloric Restriction (DCR). The targeted weekly energy deficit is designed to be similar (~30%) and a comprehensive behavioral support program will be provided to both groups. The primary outcome is weight change at the end of the 1 year intervention; follow up measures will also be obtained 6 months after completing the intervention. This study will provide robust data regarding weight loss effectiveness of IMF and will further our understanding of the impact of IMF on energy balance.

Using a randomized two-group, repeated measures experimental design, the goal of the proposed study is to investigate the efficacy of a 12-week nutrition and exercise education, physical activity, coping skills training, and home-based physical activity intervention in Hispanic women and their 3-5 year old children and 6 months of continued monthly contact to help overweight and obese Hispanic mothers improve adiposity, weight, health behaviors, and self-efficacy and their 3-5 year old children improve their adiposity and weight gain trajectory and health behaviors.
