Active clinical trials for "Obesity"

The "Primary Care Research Network for the Treatment of Adolescent Obesity" will establish infrastructure within the primary care setting to support programmatic research on weight loss for underserved adolescents, primarily urban African Americans, rural Caucasians, and Latinos. Using primary care settings, to which many youths already have entry, may increase access for underserved adolescents to participate in obesity treatment and research. The primary project will be a 12 month randomized controlled study comparing the relative effectiveness of two interventions for weight reduction: Group Condition (a family based lifestyle modification program delivered by health care providers in 23 sessions); Self-Guided Condition (a family based lifestyle modification program that combines a self-guided, home-based approach with 6 sessions delivered by health care providers).

This study is a randomized, controlled and opened trial designed to compare the effects of an interdisciplinary moderate-intensity lifestyle modification program vs. conventional treatment by primary care physicians. We want to show the benefits of coherent interdisciplinary care in the obesity clinic of CHUS (Centre Hospitalier Universitaire de Sherbrooke) in comparison to the conventional treatment in order to: Improve subjects' characteristic features of metabolic syndrome: weight, waist circumference, fatty mass, plasma lipid profile, blood pressure, fasting glycaemia, and HbA1c; Improve our patients' nutritive practices; Decrease our patients' sedentary lifestyle; Improve our patients' motivation to lose weight, and to improve their quality of life; We also wish to define predictors of answer in order to better select the patients if necessary, and evaluate the costs incurred by the health system.

Obesity is an important public health problem in the United States. The investigators hypothesize that stomach injections of botulinum toxin A (BTA), delivered through an endoscope using endoscopic ultrasound (EUS), may cause delayed gastric emptying, satiation, and reduction in body weight. This protocol is designed to study the effects and safety of gastric BTA injections. Subjects are randomized to receive placebo or one of two different doses of BTA injected into the stomach during one endoscopy, performed via the mouth. Gastric emptying, satiation, symptoms, psychological dimensions of eating behavior, and caloric intake are recorded before and after injections, and subjects are seen in follow-up for 24 weeks.

A prospective, non-randomized, open-label, multi-center study designed to implant up to twenty-six (26) CE-marked ReShape™ Balloons in twenty-six (26) patients with body mass index (BMI) 30-40 to assess the effectiveness of the device. The RIB devices will be used within their labeled indications and as per their instructions for use. Enrolled patients will be followed for seven months. The patient will be prescribed a controlled diet, exercise and counseling. One group of 26 patients will receive treatment as follows: Placement, inflate to 900 cc, remove at 180 days, follow-up 30 days post removal (endoscopic video capture of placement and removal required).

This trial asks the question: do people of much greater than average body weight need more of a drug called oseltamivir than current recommendations suggest. Oseltamivir is a drug given to people who have influenza, and currently is also being used to fight the new H1N1 influenza. Some people of larger than average body weight require larger amounts of drugs to see the same effects as others of an average body weight. No studies have ever been conducted looking at the possibility of oseltamivir being one of those drugs. Our Study's hypothesis states that those of an above average body weight will have different amounts of drug in their blood than those of people of normal body weight if they are given the normal amount prescribed for influenza. Our study will give oseltamivir to twenty people for 7 days. Half of the people will be of normal body weight and the others will be of a much higher than normal body weight. Using blood samples the investigators will determine if the amounts of oseltamivir are significantly lower in the blood of patients in the above normal body weight group.

Main objective: To describe clinical and functional characteristics of the obese hypoventilating patient; to study the relation between the obesity-hypoventilation syndrome (OHS) and the obstructive sleep apnea hypopnea syndrome (OSAHS). In the second stage of the study, to assess patient response to non-invasive mechanical ventilation (NIV) and continuous positive airway pressure (CPAP), and to identify predictors of unfavourable response to treatment. Methodology: Patients: Patients with obesity degree I-III, with pCO2 awake and at rest > 45 mmHg, with no underlying pulmonary or neuromuscular lung disease; two control groups, one of non-hypoventilating obese patients and the other of obese patients with OSAHS, will also be studied over the same period. Design: Prospective observational study. In the first stage anthropometric, clinical, functional and metabolic data will be recorded for the obese hypoventilating patients and the two control groups (obese patients without respiratory pathology, and obese patients with OSAHS). In the second stage patients with OHS will be divided into two subgroups: group 1: patients with polysomnography (PSG) suggestive of hypoventilation, in whom NIV treatment will be initiated; group 2: patients with PSG suggestive of OSAHS (apnea-hypopnea index >15), who will be administered CPAP. Patients will be examined one month and three months after the start of treatment. The same measurements will be carried out as at the beginning of the study, with the exception of the polysomnographic study. Nonetheless, pulse oximetry and arterial gases will be performed on waking. Expected Results: Patients with OHS may be characterized and differentiated from obese patients without associated respiratory pathology on the basis of clinical, functional and metabolic data. There is a group of patients with association between OSAHS and OHS that do not respond to treatment with CPAP, and this unfavorable response can be predicted in advance.

LIPO-102 is under evaluation for treatment of abdominal adiposity

The purpose of this study is to evaluate the efficacy of GFT505 80mg in reducing serum Triglycerides (TG) and increasing High Density Lipoprotein Cholesterol (HDL-C) levels compared with placebo in atherogenic dyslipidaemic patients with abdominal obesity, and to assess the tolerability and safety of once-a-day administrations of oral doses of GFT505 during 28 days.

The purpose of this study is to determine whether a 12 week Mindfulness-Based Weight Loss Maintenance (MBWLM) intervention is effective in maintaining recent loss of 10% or more of initial body weight.

Teenagers and adults who are overweight or obese have an increase in fat in the abdomen, which increases their risk for diabetes and heart disease. Reducing abdominal fat is important to reduce risk for diabetes and for heart disease. Overweight teenagers also have low levels of growth hormone compared to normal weight teenagers, and teenagers with the lowest growth hormone levels also have the greatest abdominal fat. In children who are unable to make growth hormone for other reasons, giving back growth hormone leads to a decrease in abdominal fat. We are studying whether giving growth hormone in small doses to overweight teenagers can change body composition. We hypothesize that growth hormone will cause abdominal fat to decrease and reduce the risk markers for diabetes and heart disease.
