Weight Loss Paid Clinical Trials in California

The purpose of this study to understand better how this anti-obesity medication works to assist individuals to lose weight and maintain weight loss. This study may lead to the development of other related medications for assisting people with the disease of obesity. Read Less

Metabolic syndrome and resulting downstream health effects remains a growing health concern. In published trials, the use of continuous glucose monitoring (CGM) assists behavioral changes efforts, leading to improved adherence and results from diet and exercise changes in individuals with obesity, pre-diabetes and diabetes. Mobile health (mHealth) platforms provide satisfactory, easy-to-use tools that help participants in the pursuit of weight change goals. We hypothesize that the use of CGM data and targeted coaching and nutrition education will assist with weight optimization goals in the general (non-diabetic) population using the Signos mHealth platform, with associated health benefits.

The use of continuous glucose monitoring (CGM) in earlier data has inspired behavioral changes leading to improved adherence to an exercise plan in individuals and eating habits in people with diabetes. Mobile health (mHealth) platforms provide satisfactory, easy-to-use tools to help participants in the pursuit of weight change goals. We hypothesize that the use of CGM data and the Signos mHealth platform will assist with weight control in a population of people with type 2 diabetes mellitus who are not using insulin. Read Less

This optimization trial will examine three tracking (or "self-monitoring") strategies for weight loss -- tracking dietary intake, steps, and/or body weight -- all delivered through digital health tools. The purpose of the study is to evaluate the combination of these strategies that maximizes 6-month weight loss in the context of a standalone digital health intervention for adults with overweight or obesity. The investigators will recruit 176 total participants to the trial. Recruitment will occur through remote channels. Interested individuals will be directed to an online screening questionnaire; those who are eligible will then be invited to attend an initial remote session with study personnel to ensure interest and eligibility in the study. The weight loss intervention will last 6 months, and all participants will receive a "core" treatment consisting of goal setting, behavioral lessons, action plans, and tailored feedback - all of which will be delivered remotely. Depending on which group participants are assigned to in the study, some individuals will be asked to track their dietary intake, their steps, and/or their body weight via digital tools. All study tasks will occur remotely, thus, participants never need to come in-person for any intervention or assessment tasks. The investigators will use the Multiphase Optimization Strategy (MOST) framework to identify the most effective combination of self-monitoring strategies. The factorial design will allow the research team to determine the unique and combined impact of each self-monitoring component on weight change. The primary outcome is weight change from baseline to 6 months. The research team will also assess self-monitoring engagement over 6 months and its association with weight change. To complement the main trial, the research team will also randomize half of participants to receive an interactive orientation video, in order to assess its impact on trial retention at 6 months. Overall, the information gathered from this trial will enable the construction of an optimized digital health intervention for weight loss that can be delivered remotely, which, if found to be effective, could have high potential for scalability.

Childhood obesity within the United States has been a growing concern over the past number of years, and if not addressed, leads to detrimental health outcomes for youth as they move into adulthood. The literature suggests that over-eating, especially when framed in terms of food addiction, plays a key role in this epidemic; however, treatment options are time intensive, posing a profound logistical barrier for both the child and parent and often limits or prevents engagement. As research within the field of mHealth has grown, technology-based interventions have gained traction, specifically interactive smartphone applications (apps). Displacement theory, although not new, has been understudied yet provides a strong explanation and treatment plan for addictive type behaviors. The core of this theory posits that problems which one feels they cannot face nor avoid leads to repetitive and irrepressible behaviors; however, if a healthy coping behavior can be learned and utilized, then the unhealthy behavior will cease. The theory lends itself well to being adapted into an mHealth format, making it more easily accessible and more widely used. Grounded in displacement theory, the proposed study aims to develop an app-based weight loss intervention for adolescents with obesity. Information gained regarding the feasibility and acceptability of such an intervention can potentially be replicated and applied to other populations with various addictive behaviors. Helping those with addictive behaviors in a format that has little to no logistical barriers can have a substantial impact on public health. A novel smartphone app will be designed by key stakeholders and refined through the course of the study. 46 total adolescents (14-18 years old) with %BMIp95 will be recruited via various sources (e.g., clinic referrals, flyers, social media advertising) to participate in one of two stages of the study: the beta testing stage or the trial stage. Beta testing will enroll two successive groups of eight teens to test the app for three weeks; participants will be assessed in-person pre- and post-intervention. After each group, the app will be modified to incorporate their feedback in order to promote youth engagement. The trial stage will enroll 30 adolescents to participate in a four-month intervention; participants will complete three assessments, baseline, post-intervention (both in-person) and one-month post-intervention (either in-person or virtually). The study will examine engagement and satisfaction with the app, as well as the intervention's impact on clinical outcome measures (weight and BMI, diet and snacking, and addictive behaviors related to food and substance use) and potential mediators/moderators (motivation for change, perceived stress, and distress tolerance).

The purpose of this research is to determine patient-reported outcomes after weight loss surgery, including changes in health, mood, quality of life, health satisfaction, and emotional health, in low-risk patients. Weight loss surgery has been well studied for patients with body mass index (BMI) 35 kg/m^2 or more and those with weight-related medical problems who have a BMI 30 kg/m^2 or more. However, outcomes after weight loss surgery in patients with BMI under 35 kg/m^2 and without co-morbidities have not been well studied. Read Less
