Semaglutide for Childhood Obesity

Los Angeles, California
This is a Phase 3a, randomized, parallel-controlled trial designed to compare the early re-initiation of semaglutide, starting two weeks after sleeve gastrectomy, to standard care (no pharmacotherapy following surgery). The trial will involve 150 youth with severe obesity who have been on semaglutide 2.4 mg weekly for at least 3 months prior to surgery. Participants will be randomized to either (1) semaglutide 2.4 mg weekly or (2) standard care for 24 months. Primary, secondary, and tertiary outcomes will be assessed at multiple time points: 1-month, day of surgery, and 1-, 3-, 6-, 9-, 12-, 18-, and 24-months postoperatively. We hypothesize that early re-initiation of semaglutide will be safe, well-tolerated, and lead to greater improvements in obesity, cardiometabolic risk, and eating behaviors.

Weight Loss Intervention for Breast Cancer Recurrence Prevention

Los Angeles, California
This randomized phase III trial studies whether weight loss in overweight and obese women may prevent breast cancer from coming back (recurrence). Previous studies have found that women who are overweight or obese when their breast cancer is found (diagnosed) have a greater risk of their breast cancer recurring, as compared to women who were thinner when their cancer was diagnosed. This study aims to test whether overweight or obese women who take part in a weight loss program after being diagnosed with breast cancer have a lower rate of cancer recurrence as compared to women who do not take part in the weight loss program. This study will help to show whether weight loss programs should be a part of breast cancer treatment.

Weight Loss App for Obesity

Los Angeles, California
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).

Bariatric Surgery for Obesity

Los Angeles, California
Most research to date on bariatric surgery outcomes has been about metabolic syndrome, a disorder very effectively treated by bariatric surgery. However, obesity is also associated with many other problems that have received much less attention. Amongst the most troubling of these for patients is dyspnea. Dyspnea results in substantial patient distress that can greatly reduce health-related quality of life. Little is known about the relationship between dyspnea, weight loss, and bariatric surgery. Dyspnea is a complex symptom that may lead to adaptive responses, such as the need to rest as a consequence of even minimal activity or seeking medical attention. The main outcome of the study will be measured using a new state-of-the-science validated HRQOL measure, the Patient Reported Outcome Measuring Information System for Heart Failure (PROMIS+HF 27).

Trevogrumab + Garetosmab + Semaglutide for Obesity

S. Gate, California
This study is researching experimental drugs called trevogrumab and garetosmab (called "study drugs") in combination with another drug, semaglutide (Wegovy®). This study will be done in 3 parts, Part A, Part B, and Part C where different study drugs will be tested. Part A of the study is focused on healthy participants. Part B and C of the study is focused on participants with obesity. The aim of Part A of the study is to see how safe and tolerable the study drug is in healthy participants. The aim of Part B and Part C of the study is to see how safe and effective the study drug is when combined with Wegovy. Parts A, B, and C of the study are looking at several other research questions, including: * What side effects may happen from taking the study drug * How much study drug is in the blood at different times * Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)

TOTAL Program for Obesity

West Los Angeles, California
Nearly 8 in 10 Veterans meet criteria for overweight/obesity. Three evidence-based treatment options are available within VA (behavioral weight management \[MOVE!\], obesity medications, and bariatric surgery). However, all treatments are significantly underutilized. This study will evaluate the effectiveness of a novel intervention designed to increase obesity treatment initiation and subsequently weight loss within VA. The intervention, Teaching Obesity Treatment Options to Adult Learners (TOTAL), involves an educational video and multiple motivational sessions delivered via telemedicine. If effective, TOTAL could be implemented throughout VA without requiring significant resources and could be integrated into the existing VA behavioral weight management program, MOVE!, which is present at nearly every VA medical center.

Why Other Patients Applied

"I have tried to lose weight, but as I get older, it becomes harder and harder. I have lost weight in the past through diet and exercise, but it has been more difficult to accomplish as I age."

JP
Obesity PatientAge: 44

"I am applying for my daughter. She turns 12 this year and is overweight. She's 5'4" and 176 pounds. Would be great to enroll her in a clinical trial to see if this form of care could work for her. Realize that there's no guarantee, but I support her and we'd like to give it a try."

MW
Parent of PatientAge: 46

"I need to lose weight because it's affecting my knees. I've already had a knee replacement and the second one is happening on the left knee in a few months. I've participated in a study in the past for a skin-related issue, and had a good experience. That's why I'm interested in joining a study for wieght loss."

KI
Obesity PatientAge: 69

"I have a heart condition, and my fat is all in my chest, surrounding my heart. It's hard for me to exercise because my legs are thin and the upper body weight is too much — putting strain on my leg joints. It’s a vicious cycle. I am also post-menopausal, which adds additional weight loss difficulty. I also have stress with being a full time caregiver for my mom. I'm interested in trying a clinical trial."

DK
Obesity PatientAge: 56

"I changed my diet in 2020 and I’ve lost 95 pounds from my highest weight (283). I am 5’3”, female, and now 188. I still have a 33 BMI. I've been doing research on alternative approaches to continue my progress, which brought me here to consider clinical trials."
