Mazdutide for Adults With Prediabetes: A Randomized, Double-Blind, Placebo-Controlled Trial (DREAM-PRE)

Registered Phase 4 interventional trial (not yet recruiting). Prediabetes affects millions of adults worldwide and carries a high risk of progression to type 2 diabetes. Mazdutide is a once-weekly injectable drug that activates both GLP-1 and glucagon receptors, lowering blood sugar and body weight simultaneously. This study (DREAM-PRE) tests whether mazdutide can help adults with prediabetes return to normal blood sugar levels. Approximately 150 adults aged 18-75 years with prediabetes and BMI ≥22 kg/m² will be randomly assigned in equal numbers to one of three groups: mazdutide 4 mg once wee

Precision Obesity Medicine: Genetic Prediction of Response to GLP-1/GIP Agonists.

Registered observational trial (recruiting). Obesity is a chronic multifactorial disease with a strong genetic component. Although glucagon-like peptide-1 (GLP-1) receptor agonists such as semaglutide and dual glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 receptor agonists, such as tirzepatide, are highly effective treatments for obesity, substantial inter-individual variability in weight loss response remains. Genetic factors may contribute to these differences in treatment outcomes. The aim of this prospective cohort study is to investigate whether a Genetic Risk Score (GRS) and s

Mindfulness-Based Nutrition Group Therapy as an Adjunct to GLP-1 Treatment of Obesity

Registered N/A interventional trial (active not recruiting). The goal of this clinical trial is to learn whether a mindfulness-based nutrition group program is feasible and acceptable for adults with obesity who are taking GLP-1 receptor agonist medication and receiving usual medical care, including dietetic counselling. The main questions this study aims to answer are: Can this group program be successfully carried out with adults receiving GLP-1 treatment? Do participants find the program useful, acceptable, and manageable? Are participants willing to attend the sessions, complete the home e

Genetic, Microbiological and Behavioral Factors in Obesity

Registered observational trial (recruiting). This study will assess the impact of genetic markers, microbiological (microbiome) and behavioral factors on tolerance, adherence and effectiveness of dual GLP1/GIP RA in the treatment of obesity. 200 consecutive patients who meet all inclusion and none of the exclusion criteria will be enrolled.

Interleukine-2 (IL-2) Plus Semaglutide in Alzheimer's Disease

Registered Phase 1/Phase 2 interventional trial (recruiting). Alzheimer's disease (AD) is the most common cause of dementia. Despite major research efforts, effective treatments that slow or stop disease progression remain limited. Growing evidence suggests that inflammation in the brain and the body plays a key role in the onset and progression of AD. In particular, immune cells called regulatory T cells (Tregs), which normally help control inflammation, are impaired in AD individuals. This leads to increased activity of harmful immune pathways that worsen brain injury. Interleukin-2 (IL-2) i

Hydration Intervention to Decrease Side Effects Associated With GLP - 1 RA Therapy

Registered N/A interventional trial (recruiting). This is a 17 - week study consisting of a one - week run - in period and a 16 - week intervention. The 16 - week pilot interventions aims to increase hydration in those beginning GLP - 1 RA therapy. Investigators aim to increase hydration to potentially decrease side effect severity, amount of side effects, and drug discontinuation associated with GLP - 1 RA therapy. The investigators are piloting to assess feasibility and preliminary efficacy of the intervention through examining participant retention, participant feedback, researcher and part

Glucagon-Like Peptide-1 Receptor Agonists to Attenuate Metabolic Risk in Individuals With Duchenne Muscular Dystrophy

Registered Phase 1/Phase 2 interventional trial (not yet recruiting). Duchenne Muscular Dystrophy (DMD) is a rare, genetic disease that leads to muscle weakness, breathing difficulties, heart disease, and early death. Approximately half of individuals with DMD have elevated body mass indices (BMIs) in the overweight or obesity range. High BMI is due to a combination of factors including limited mobility and steroid medications, which are used to treat DMD. There are new medications, glucagon-like peptide-1 receptor agonists (GLP-1 RAs) that promote weight loss in the general population. GLP-1

Tirzepatide-Based Prehabilitation Before Elective Ventral and Incisional Hernia Repair in Patients With Obesity

Registered observational trial (completed). This study evaluated whether a 16-week weight-loss program using tirzepatide before elective ventral and incisional hernia surgery could improve surgical readiness and outcomes in patients with obesity. In this retrospective multicenter study, 109 patients entered the program, and 91 completed treatment and underwent surgery. Participants achieved an average weight loss of 13.8%, and all patients who completed the program reached the target weight required for surgery. Compared with a control group of obese patients who underwent hernia repair withou

GLP-1 Therapy After Bariatric Surgery in Chinese Patients With Obesity

Registered N/A interventional trial (recruiting). Obese patients exhibit considerable heterogeneity and complex comorbidities, making long-term effective management challenging with monotherapy. While bariatric surgery remains the most effective weight-loss intervention, postoperative weight regain and metabolic deterioration remain significant concerns. glucagon-like peptide-1 receptor agonists (GLP-1RA) offer distinct advantages for weight loss and metabolic control, and their combination with surgery may produce synergistic effects. This study investigates the efficacy and safety of bariatr

Tirzepatide on Atrial Fibrillation Recurrence After Catheter Ablation in Patients With Obesity and HFpEF

Registered Phase 4 interventional trial (not yet recruiting). This multicenter, randomized, open-label, blinded-endpoint trial evaluates whether weekly subcutaneous tirzepatide for 12 months reduces atrial fibrillation (AF) recurrence after catheter ablation in adults with obesity and heart failure with preserved ejection fraction (HFpEF). HFpEF is diagnosed by direct intraprocedural measurement of mean left atrial pressure (mLAP ≥ 15 mmHg at rest) during the ablation procedure, providing a hemodynamically anchored, homogeneous study population free from the diagnostic ambiguities of N-termina
