Obesity clinical trials at UCSD
21 in progress, 10 open to new patients

  • Cue-Reward Learning and Weight Gain in Youth

    open to eligible people ages 8–11

    The objective of the study is to compare children at low risk for obesity (two healthy weight parents) to children at high risk for obesity (two overweight parents) in their response rate to food taste and in their rate of learning using fMRI.

  • Effect of Vestibular Stimulation on Fat Consumption and Energy Expenditure as Assessed Using Indirect Calorimetry

    open to eligible people ages 18–65

    There is an ongoing and worsening problem with obesity in the developed, and much of the developing world. Although it has long been realized that Western diets that are rich in sugar and fat play an important role in this, it has only recently been realized that exposure to these diets, particularly in childhood, can damage the part of the brain that determines how much fat there is in the body. The result of this damage is that the so-called "set-point" for fat in this part of the brain is pushed upwards. There is a lot of evidence from animals that activating the brain's balance (vestibular) system pushes this set-point for fat downwards to cause fat loss, probably because this "tricks" the brain into thinking that there is increased physical activity. The aim of this study is to see whether non-invasive electrical stimulation of the vestibular system in human participants causes a change in metabolism of fat and/or energy expenditure, which, if regulated upwards, would suggest this could be used as a means of reducing body fat in humans.

  • FRESH-DOSE: Families Responsibility Education Support Health—Dual Options for Sustained Effectiveness

    open to eligible people ages 7–12

    The objective of the study is to evaluate whether a less intensive intervention, Guided Self-Help Family Based Treatment (gshFBT), is non-inferior to the more intensive Family Based Treatment (FBT) for childhood obesity on child weight loss over 18-months. Cost-effectiveness of both treatments will also be compared.

  • Guided Self-Help Obesity Treatment in the Doctor's Office - GOT Doc

    open to eligible people ages 5–13

    One-third of our nations' children are overweight or obese (OW/OB). The cornerstone of obesity treatment involves intensive family-based behavioral therapy, yet these programs often exist in tertiary care academic settings that have long wait lists and are too far away for families to access. Primary care providers (PCP) have been called on by several organizations to be the front line of obesity management, yet they are limited by a lack of time, resources, and skills. Thus, if we are to offer effective obesity management in the healthcare setting, other care models need to be developed and tested. The goal of this proposal is to deliver Guided Self-Help (GSH) treatment of childhood obesity in the primary care setting. This program relies on classic behavioral therapy strategies, self-regulation theory, and provides the support needed for patient/family self-management of weight loss. Implementing this program in the primary care setting will increase our ability to deliver nutrition and weight-related counseling in the primary care office and serve patients closer to home, thereby increasing access to effective treatment, improving adherence to recommended changes, and meeting the goals of Healthy People 2020.

  • Reinforced Enhanced - Families Responsibility Education Support and Health

    open to eligible people ages 7–12

    The purpose of this application is to evaluate whether a pediatric weight control program that incorporates comprehensive parenting training with behavioral therapy can increase weight loss in children compared to traditional family-based behavioral therapy programs. Since certain parenting styles are associated with greater weight loss during interventions and appear to enhance the impact of key behavioral strategies, adding parenting training to these interventions may increase the overall effectiveness of these programs and increase our ability to help children obtain a healthy weight. This project could result in identifying an improved method of pediatric obesity treatment that provides additional benefits to the growth and development of children via improved self-regulatory behaviors.

  • The Effects of Type 1 Diabetes Mellitus and Increased Weight on Gut Microbiome and Urine Metabolome Profiles in Children

    open to eligible people ages 7–17

    This study employs a cross-sectional design to profile the gut microbiome and urine metabolome in overweight/obese children with type 1 diabetes (T1D).

  • The Impact of Time Restricted Feeding (TRF) in Improving the Health of Patients With Metabolic Syndrome

    open to eligible people ages 18 years and up

    The investigators intend to measure the health impact of a dietary intervention known as time restricted feeding (TRF) on patients with metabolic syndrome (three or more of: increased waist circumference, abnormal cholesterol levels, elevated blood pressure, or elevated blood sugar). The investigators will enroll patients with metabolic syndrome who eat for ≥ 14 hours per day and will ask participants to reduce daily oral intake to 10 hours per day. The investigators will assess the impact of this dietary change using measures obtained before and after a 12 week intervention period, including body mass index, blood pressure, various lab parameters and blood sugar levels (assessed using a continuous glucose monitor). The investigators will assess for compliance with TRF using a Smart Phone application (myCircadianClock (mCC) app).

    La Jolla, California

  • Transvaginal NOTES Sleeve Gastrectomy

    open to eligible females ages 18–75

    This is a prospective chart review/data collection study of natural orifice translumenal endoscopic surgery (NOTES) for sleeve gastrectomy, that will include questionnaires administered throughout the study. Subjects enrolled will be those intending to have a transvaginal NOTES sleeve gastrectomy. Data will be collected and reviewed through 12 months post-op.

  • UCSD Get Fit, Be Fit Study

    open to eligible people ages 21 years and up

    The purpose of the Get Fit, Be Fit Study is to examine the effect of incorporating pistachios in an intensive 4-month cognitive-behavioral weight loss intervention in overweight and obese men and women, to examine effects on metabolic factors, and to monitor and examine changes in dietary intake and food choices during the intervention, in a randomized controlled study.

  • Vestibular Stimulation to Trigger Adipose Loss Clinical Trial

    open to eligible people ages 22–80

    There is an ongoing and worsening problem with obesity in the developed, and much of the developing world. Although it has long been realized that Western diets that are rich in sugar and fat play an important role in this, it has only recently been realized that exposure to these diets, particularly in childhood, can damage the part of the brain that determines how much fat there is in the body. The result of this damage is that the so-called "set-point" for fat in this part of the brain is pushed upwards. There is a lot of evidence from animals that activating the brain's balance (vestibular) system pushes this set-point for fat downwards to cause fat loss, probably because this tricks the brain into thinking that the animal is more physically active. The aim of this study is to see whether the same effect can be triggered in humans by non-invasively stimulating the vestibular system with a small electrical current through the skin behind their ears.

  • Extracellular microRNA: Biomarkers of Endothelial Dysfunction in Obese Adolescents & Adults With Obstructive Sleep Apnea

    Sorry, not yet accepting patients

    Using a prospective observational approach and a clinical trial design comparing the effectiveness of continuous positive airway pressure to diet and exercise, investigators plan to evaluate how obstructive sleep apnea (OSA) leads to endothelial dysfunction in adolescents and young adults and whether treatment of OSA can improve endothelial dysfunction. Concurrently, investigators will measure miR 92a/miR 210 levels in all subjects at baseline and following therapy to determine whether miR 92a/miR 210 levels reliably predict endothelial dysfunction in patients and responses to therapy.

  • Modeling the Neurological Basis and Characterizing the Neurological Phenotype of Obesity Using Human Neural Stem Cells

    Sorry, not yet accepting patients

    This study aims to characterize the neurological basis of obesity and response to surgical and medical treatment by inducing adult pluripotent stem cells into neuronal cells from subjects that have demonstrated extreme response to bariatric surgery or pharmacological treatment for obesity.

  • Trial of Roflumilast in Asthma Management (TRIM)

    Sorry, not yet accepting patients

    There are currently no treatments to specifically target asthma in obese adults. This pilot study is being conducted to investigate how effective roflumilast is in treating asthma in participants that have a higher BMI. Roflumilast can induce weight loss, which may lead to improved asthma control. The primary objective of TRIM is to perform a pilot placebo-controlled trial of roflumilast for the treatment of poorly controlled obese asthmatics.

  • Pelvic Radiation Therapy or Vaginal Implant Radiation Therapy, Paclitaxel, and Carboplatin in Treating Patients With High-Risk Stage I or Stage II Endometrial Cancer

    Sorry, in progress, not accepting new patients

    This randomized phase III trial studies pelvic radiation therapy to see how well it works compared with vaginal implant radiation therapy, paclitaxel, and carboplatin in treating patients with high-risk stage I or stage II endometrial cancer. Radiation therapy uses high-energy x-rays to kill tumor cells. Implant radiation therapy uses radioactive material placed directly into or near a tumor to kill tumor cells. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether pelvic radiation therapy alone is more effective than vaginal implant radiation therapy, paclitaxel, and carboplatin in treating patients with endometrial cancer.

  • PREDICT: Nutrigenetic Profile of Patients With Weight Loss Success

    Sorry, accepting new patients by invitation only

    This observational study will investigate the potential clinical utility of the Pathway Fit® test by investigating whether patients who successfully lose weight (defined as losing at least 5% of body weight 8 weeks after initiation) in the MOVE! or TeleMOVE! Weight Management programs have a distinct nutrigenetic profile over those that were unable to lose a significant amount of weight. We will use electronic records to identify all individuals who have successfully completed the MOVE! program (i.e. attended the full 8 week course) or TeleMOVE! program. In addition we will find age- and gender- matched individuals who attended and completed the MOVE! or TeleMOVE! programs but did not lose weight. After completion of the MOVE! or TeleMOVE! programs Veterans will submit a saliva sample for the Pathway Fit® test. Also, blood will be collected for storage for further studies on metabolomics. The start and end weight of all participants will be recorded. The nutrigenic profiles of those with successful weight loss will be compared to those less successful to determine if this cohort has a particular genetic profile.

  • Unidas Por la Vida: A Healthy Lifestyle Intervention for High-risk Latina Dyads

    Sorry, accepting new patients by invitation only

    Mexican American women have significantly elevated rates of obesity and type 2 diabetes. The proposed study tests a novel intervention that capitalizes on an existing important family dyad (mothers and their adult daughters) to foster clinically significant and long-lasting health behavior change. If found to effective, this intervention strategy has great potential to address health disparities in this, and other, at-risk populations.
