NCT ID: NCT04839237 Withdrawn - Obesity Clinical Trials

NCT ID: NCT04399395 Withdrawn - Obesity Clinical Trials

Naltrexone/Bupropion (Mysimba) to Optimize Weight Outcomes After Obesity Surgery

Start date: November 1, 2020
Phase: Phase 4
Study type: Interventional

Limited/poor weight loss and weight regain are concerns following bariatric surgery, and weight regain may increase the risk for relapse of comorbidities related to obesity. Medications for weight reduction may assist further weight loss, and support weight maintenance, with positive effects on comorbidities. This pilot study will examine the effect of naltrexone/bupropion and lifestyle advice versus lifestyle advice alone for 7 months in patients with a suboptimal weight trajectory (either little weight loss or weight regain) 2 years or later following bariatric surgery.

NCT ID: NCT04077385 Withdrawn - Obesity Clinical Trials

Memory-Updating Technique to Reduce Food Craving and High Calorie Food Intake Among Individuals With Overweight/Obesity

Start date: October 2, 2020
Phase: N/A
Study type: Interventional

This study will evaluate the effects of retrieval-extinction (R-E) training on responding to high calorie foods including self-report craving, physiological responding, and high calorie food intake in adults with overweight/obesity. R-E training aims to update the memories that associate cues (i.e., high calorie food) with reward (i.e., consumption). R-E training involves "retrieving" these cue-reward associative memories through brief presentation of relevant cues, resulting in instability of the memories and providing an opportunity to be updated via reconsolidation. Presenting relevant cues while not allowing consumption (i.e., extinction training) during reconsolidation can modify the unstable cue-reward memories, resulting in lasting reductions of craving and intake. This study will be the first to test the effects of R-E training on craving for and intake of high calorie foods in humans. To examine the effects of R-E training on food craving, physiological response (heart rate, skin conductance, salivation), and food intake, 150 adults with overweight/obesity will complete baseline food cue-reactivity and intake tasks in the lab. Participants will be randomized to observe high calorie food cues (i.e., "retrieval" of food cue-reward memories; R-E training group) or non-food cues (i.e., no retrieval of food cue-reward memories; extinction control group) and engage in 60 min of extinction training for high calorie foods. R-E/extinction control training will occur on two consecutive days and four follow-up food cue-reactivity sessions through 3 months. Weight will be assessed at each session and in-lab food intake at 1- and 3-months. Recent food/drink intake will also be assessed at each session. Some participants (n=75) will complete a pilot portion of the study involving real-world data collection of naturally-occurring food cues, craving, and food intake via smartphone. It is hypothesized that: (1) R-E training (vs. extinction control) will decrease high calorie food cue-reactivity (self-report craving, heart rate, skin conductance, salivation) and intake assessed in the lab, as well as self-report craving and food intake assessed in the real world; and (2) decreased high calorie food cue-reactivity will be a mechanism through which R-E training reduces high calorie food intake at follow-up. The Principal Investigator will explore associations between lab and real-world cue-elicited craving and food intake, and the effect of R-E training on weight.

Activity, Adiposity, and Appetite in Adolescents 2

Start date: May 7, 2019
Study type: Observational

Our goal is to examine linkages between physical activity, appetite control, and energy metabolism in adolescents. We will assess metabolic function and appetite control in male and female adolescents stratified by bodyweight and physical activity using across-sectional study design.

NCT ID: NCT03796416 Withdrawn - Clinical trials for Induction of Labor Affected Fetus / Newborn

Obesity Study to Assess Induction of Labor

Start date: December 1, 2019
Phase: N/A
Study type: Interventional

There are more and more pregnant women who are obese. It is very difficult for obese women to get into labor. That is why when women are obese, half are likely to need a Cesarean delivery(C-section). Unfortunately, C-sections are more dangerous for obese women. There may be a combination of issues that cause obese women to need C-sections. We believe one of those reasons is that the womb of obese women respond differently to medications and devices compared to non-obese women. There are commonly two ways to help women get into labor. One way is a medication called misoprostol. The second way is a device called Foley balloon. In most studies, both ways are equally effective in helping women get into labor. However, these studies included everyone, and didn't focus on obese women. So far there are no studies in this area that focus only on obese women. Therefore we need to design this study to focus just on obese women and what is the best way to help them get into labor and avoid a C-section.

NCT ID: NCT03708913 Withdrawn - Metabolic Syndrome Clinical Trials

Neuromodulation for Hypothalamic Obesity

Start date: June 1, 2019
Phase: N/A
Study type: Interventional

The balance between hunger and satiety is imperative for an individual's survival and overall health.). Without this balance, individuals can become morbidly obese or lack adequate nutrition for survival. Craniopharyngioma (CP) is a benign tumour that occurs at the base of the brain in children. Unfortunately, pediatric neurosurgeons sometimes inadvertently destroy a child's satiety centre during CP tumour removal surgery. This leaves the child with a post-operative complication: an insatiable appetite. This form of obesity is called "hypothalamic obesity". This study is designed to investigate Deep Brain Stimulation for hypothalamic obesity in n=6 young adults who have stabilized tumours.

NCT ID: NCT03675074 Withdrawn - Obesity Clinical Trials

Neujia Anastomosis for Treatment of Obesity and Type II Diabetes

Start date: September 12, 2018
Phase: N/A
Study type: Interventional

This prospective, multicenter, open label, single arm study will enroll subjects presenting with obesity and inadequately controlled type II diabetes (T2DM). A dual path jejunoileal side-to-side anastomosis is endoscopically created using the Neujia device. Subjects are followed for 12 months and annually thereafter for up to 5 years to assess change in metabolic parameters, medications, weight, and adverse events.

NCT ID: NCT03579043 Withdrawn - Obesity Clinical Trials

The Effects of Beverages on Food Liking

Start date: May 22, 2018
Phase: N/A
Study type: Interventional

The use of non-nutritive sweeteners (NNS) in replacement of nutritive sweeteners (NS) could be a potential weight loss strategy as it may reduce energy intake. One concern with the replacement of NS with NNS is the risk of caloric compensation after consumption of NNS. Most studies have examined the effect of NNS foods and beverages on energy intake in the short-term (one-day or less), with results suggesting lack of compensation in the very short-term (less than one day), and then compensation, or over compensation, when the NNS products are consumed on one day with measures of energy intake taken over 1 to 2 days (Anton et al., 2010; Lavin et al., 1997; Overduin et al., 2016; Appleton et al., 2007; Piernas et al., 2013). Given these mixed results, it is still not clear if NNS foods and beverages are a beneficial strategy for decreasing energy intake. However most studies have been in lab-based settings, in which participants are consuming provided food at specific times. No study has reported on the effect of NNS foods or beverages consumed over several days and energy intake on these days when participants are in free-living situations. Therefore, the purpose of this investigation is to evaluate how NNS beverage consumption affects energy intake in free-living situations over a span of three days. Through a 3x4 mixed design, participants will be randomized into one of three groups: NNS beverage, NS beverage, or carbonated water (control). Participants will be encouraged to go about their normal daily activities and not change any other aspect except for drink consumption. One baseline and three, 24-hour dietary recalls will be collected over the course of the study to analyze energy intake. The specific aim of this investigation is to determine if caloric compensation occurs during 3-day exposure to NNS beverages.
