Time-Restricted Eating vs. Calorie Restriction for Weight Loss and Colorectal Cancer Risk Reduction

Chicago, Illinois
Approximately 42% of American adults are obese, and this condition is strongly related to the development of colorectal cancer. Innovative lifestyle strategies to treat obesity and reduce colorectal cancer risk are critically needed. This research will demonstrate that time-restricted eating, a type of intermittent fasting, is an effective therapy to help obese individuals reduce and control their body weight and prevent the development of colorectal cancer.

Behavioral Intervention + Technology for Weight Loss

Chicago, Illinois
Obesity and cardiometabolic risks are significant public health issues, with about two-thirds of U.S. adults overweight or obese. Weight loss can prevent these health problems, but current lifestyle interventions have limited success. New, effective strategies are needed to address this rising issue at the population level. The goal of this clinical trial is to investigate how a behavioral intervention combined with technology impacts weight loss in young adults. The main questions it aims to answer are: • How does the combination of behavioral intervention and technology influence weight loss in young adults?

Sleeve Gastrectomy + Tirzepatide for Obesity

Chicago, Illinois
This study examines whether adding tirzepatide-a medication that helps with weight loss-after sleeve gastrectomy surgery can help people lose more weight after the surgery; better improve conditions like Type 2 diabetes, high blood pressure, high cholesterol, and sleep apnea after surgery and; whether this causes more complications or side effects compared to surgery alone.

SMARTer Weight Loss Management for Obesity

Chicago, Illinois
The SMARTer trial will be a three-arm, randomized controlled non-inferiority trial that compares the optimized, adaptive SMARTer intervention, fixed DPP, and Self-Guided (Control). The trial will address whether a scalable, stepped-care intervention can stand up to gold-standard DPP by achieving comparable weight loss at a lower cost. Alongside evaluation of clinical non-inferiority, a comprehensive economic evaluation will inform relative affordability. Cost information is important to inform treatment policy and change standard of care, but is sorely lacking for behavioral interventions. The SMARTer intervention reduces costs by initially offering minimal intervention to all and stepping up to offer more costly treatment components only to non-responders who fail to attain the target weight loss. A rigorous economic evaluation planned and designed alongside the SMARTer trial will provide an accurate, robust head-to-head comparison of costs, cost-effectiveness, and projected lifetime health care costs between the three arms.

Exercise and Weight Loss for Obese PAD Patients

Chicago, Illinois
The PROVE Trial is a randomized clinical trial that will determine whether a weight loss intervention combined with walking exercise achieves greater improvement or less decline in six-minute walk distance at 12 month follow-up than walking exercise alone in people with PAD and BMI\>25 kg/m2. The intervention uses a Group Mediated Cognitive Behavioral framework, connective mobile technology, remote monitoring by a coach, and a calorie restricted Dietary Approaches to Stop Hypertension (DASH)-derived Optimal Macronutrient Intake Trial for Heart Health (OMNIHeart) diet. 212 participants with PAD and BMI \> 25 kg/m2 will be randomized to one of two groups: weight loss + exercise (WL+EX) vs. exercise alone (EX). Participants will be randomized at Northwestern, Tulane University, and University of Minnesota. Our primary outcome is change in six-minute walk distance at 12-month follow-up. Secondary outcomes are change in 6-minute walk distance at 6-month follow-up and change in exercise adherence, physical activity, patient-reported walking ability (measured by the Walking Impairment Questionnaire (WIQ) distance score), and mobility (measured by the Patient-Reported Outcomes Measurement Information System \[PROMIS\] mobility questionnaire) at 12-month follow-up. Tertiary outcomes are perceived exertional effort (measured by the Borg scale at the end of the 6-minute walk at 12-month follow-up), and diet quality. Exploratory outcomes consist of change in the short physical performance battery (SPPB), the WIQ stair climbing and walking speed scores, and calf muscle biopsy measures at 12-month follow-up. Study investigators will perform calf muscle biopsies in 50 participants to compare changes in mitochondrial biogenesis and activity, capillary density, and inflammation between WL+EX vs. EX.

Weight Loss Intervention for Breast Cancer Recurrence Prevention

Chicago, Illinois
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.

Mediterranean Diet + Lifestyle Changes for Colorectal Cancer Prevention

Chicago, Illinois
A Mediterranean Diet (MedDiet), a largely plant-based dietary pattern, is relevant to CRC prevention and microbial production of anti-cancer metabolites in observational studies. A MedDiet can shift BA metabolism as shown in primates and when combined with calorie restriction, shows superior adherence and weight control in humans, given its palatability. To date, no studies have tested in an RCT the effects of a MedDiet alone (MedA), WL through lifestyle intervention (WL-A) or a calorie-restricted MedDiet for WL (WL-Med) on the BA-gut microbiome axis and its relevance to CRC prevention among AAs. A multidisciplinary team combining expertise in psychology, nutrition, microbiology, molecular cell biology, computational biology, medicine and biostatistics, proposes to conduct a four-arm RCT in which 232 obese AAs, 45-75 years old complete one of the following 6-month interventions: Med-A, weight stable; WL-A, calorie restriction with no diet pattern change; WLMed; or Control. The investigators will use samples and data collected at baseline, mid-study (month-3) and post-intervention to compare the effects of the interventions on 1) Concentration and composition of circulating and fecal BAs; 2) Gut microbiota and metabolic function; and 3) Gene expression profiles of exfoliated intestinal epithelial cells.

BI 456906 for Diabetes and Obesity

Skokie, Illinois
This study is open to adults who are at least 18 years old and have a body mass index of 27 kg/m² or more. People can take part if they have type 2 diabetes and if they are currently being treated only with diet and exercise or with specific diabetes medications. Only people who have previously not managed to lose weight by changing their diet can participate. The purpose of this study is to find out whether a medicine called survodutide (BI 456906) helps people living with overweight or obesity who also have diabetes to lose weight. Participants are divided into 3 groups by chance, like drawing names from a hat. 2 groups get different doses of survodutide and 1 group gets placebo. Placebo looks like survodutide but does not contain any medicine. Every participant has a 2 in 3 chance of getting survodutide. Participants inject survodutide or placebo under their skin once a week for about one and a half years. In addition to the study medicine, all participants receive counselling to make changes to their diet and to exercise regularly. Participants are in the study for about 1 year and 7 months. During this time, it is planned that participants visit the study site up to 14 times and receive 6 phone calls by the site staff. The doctors check participants' health and take note of any unwanted effects. The study staff also regularly measure participants' body weight. The results are compared between the groups to see whether the treatment works.

Why Other Patients Applied

"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."

"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."

TOTAL Program for Obesity

Madison, Wisconsin
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.

Revita DMR for Obesity

Brownsburg, Indiana
Fractyl is evaluating Revita Duodenal Mucosal Resurfacing (DMR) in the REMAIN-1 pivotal study, which is designed to include two cohorts - an open label cohort referred to as REVEAL-1, and a randomized cohort, which includes both a midpoint analysis and a pivotal analysis. Patients who previously lost at least 15% of their body weight on a GLP-1 can qualify for the open label REVEAL-1 cohort. The data generated from the REVEAL-1 cohort will be used for open label reporting as the study progresses. The REMAIN-1 randomized cohort will enroll patients living with obesity and a body mass index ("BMI") between 30 and 45 kg/m2 who are not currently on a GLP-1 drug. Patients will be prescribed tirzepatide and titrated to achieve at least 15% total body weight loss, at which time tirzepatide will be discontinued and patients will be randomized to Revita versus sham at 2:1. Midpoint Analysis of Randomized Cohort: The midpoint analysis of the randomized cohort will be performed at three months of follow-up on approximately 45 patients, allowing us to assess and report on safety and efficacy signals that could be anticipated in the pivotal analysis. These patients are distinct from those included in the pivotal analysis. Pivotal Analysis of Randomized Cohort: The pivotal analysis of the randomized cohort will be performed on approximately 315 patients (distinct from those included in the midpoint analysis) and will evaluate safety and efficacy in the first co-primary endpoint, which is weight regain from the time of tirzepatide discontinuation in Revita DMR versus sham patients at six months, with a primary objective of demonstrating a benefit of Revita DMR versus sham for weight maintenance after GLP-1 discontinuation. The second co-primary endpoint evaluates a responder rate among the Revita DMR treated group at one year to demonstrate the durability of the Revita DMR procedure for weight maintenance after discontinuation of a GLP-1-based therapy. Secondary objectives will include evaluation of the effectiveness of the Revita DMR procedure on the change in blood glucose levels, cardiovascular disease ("CVD") risk factors, body composition and pre-diabetes status. All patients enrolled in the study will receive diet and lifestyle counseling.
