What is the purpose of this trial?

The purpose of this Phase-2 chronic weight management master protocol (CWMM) is to create a framework to evaluate the safety and efficacy of various investigational interventions for chronic weight management with intervention-specific appendices (ISAs). The CWMM establishes entry criteria for newly enrolled participants across the master and the ISAs. The ISAs may start independently of other ISAs as interventions become available for clinical testing. The results for the CWMM screening record will be reported when all the ISA's complete.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is semaglutide safe for humans?

Semaglutide has been studied for its safety in treating obesity, and it is generally considered safe for humans. It has been approved by the US Food and Drug Administration for chronic weight management, with studies showing improvements in weight loss and cardiovascular risk factors. ^{1 2 3 4 5}

How is the drug LY900038 (Semaglutide) unique for treating obesity?

Semaglutide is unique for treating obesity because it is a once-weekly injection that helps reduce appetite and energy intake, leading to weight loss. It also improves cardiometabolic risk factors, which are important for heart health, in people with obesity. ^{2 5 6 7 8}

What data supports the effectiveness of the drug LY3305677 for obesity?

Research shows that semaglutide, a component of LY3305677, is effective for weight loss, with studies indicating it can lead to a 15% reduction in body weight over 68 weeks. It is considered a 'game changer' in obesity treatment, providing significant and sustained weight loss compared to other available medications. ^{1 4 5 9 10}

Published Research Related to This Trial

In a 20-week trial with 72 adults, once-weekly subcutaneous semaglutide 2.4 mg significantly reduced appetite and energy intake, leading to a 9.9% reduction in body weight compared to only 0.4% with placebo.

Semaglutide improved participants' control over eating and reduced food cravings without causing delayed gastric emptying, indicating its efficacy in managing obesity without adverse effects on gastric function.

Semaglutide, a glucagon-like peptide-1 receptor agonist, has been shown to produce the largest weight loss of any obesity medication, with an average reduction of about 15% of initial body weight over 68 weeks.

In addition to significant weight loss, semaglutide also improves cardiovascular risk factors and physical functioning, making it a promising option for chronic weight management.

Semaglutide for the treatment of obesity. Chao, AM., Tronieri, JS., Amaro, A., et al.[2023]

Semaglutide, a once-weekly glucagon-like peptide-1 receptor agonist, has been shown to achieve significant and sustained weight loss in individuals with obesity, surpassing results from previous weight-loss medications, and has been approved for use alongside diet and exercise.

Emerging treatments like tirzepatide and cagrilintide are demonstrating even greater weight loss effects than semaglutide, indicating a shift towards more effective 'weight-centric' strategies for managing obesity and related conditions like type 2 diabetes.

Once-weekly 2.4 mg Semaglutide for Weight Management in Obesity: A Game Changer? Colin, IM., Gérard, KM.[2022]

Obesity is a major public health concern, with projections indicating that over 1.1 billion individuals will be affected by 2030, highlighting the urgent need for effective treatments.

GLP-1 receptor agonists, particularly semaglutide, are at the forefront of clinical development for obesity treatment, showing promise in improving metabolic health and potentially serving as a benchmark for future anti-obesity therapies.

In a phase 3 trial involving 667 adults with overweight or obesity, oral semaglutide 50 mg taken daily resulted in a significant average weight loss of 15.1% compared to only 2.4% with placebo over 68 weeks, demonstrating its efficacy in weight management.

While semaglutide was effective, it was associated with a higher incidence of adverse events, particularly gastrointestinal issues, affecting 80% of participants, indicating that while it is effective, monitoring for side effects is important.

In two phase III trials involving 2764 participants with overweight or obesity, semaglutide 2.4 mg once weekly significantly improved cardiometabolic risk factors, including reductions in waist circumference, blood pressure, and fasting glucose compared to placebo.

The benefits of semaglutide were not sustained after stopping the treatment, indicating that ongoing administration may be necessary to maintain improvements in health outcomes.

High-dose once-weekly semaglutide has been shown to significantly reduce weight in patients with obesity or overweight, as demonstrated in four phase 3 clinical trials involving various populations, including those with diabetes.

While gastrointestinal side effects were common, semaglutide was generally well tolerated and also led to improvements in cardiometabolic risk factors, such as waist circumference and blood pressure.

Semaglutide, approved by the FDA on June 4, 2021, is the first new drug for chronic weight management in adults with obesity or overweight since 2014, specifically targeting those with a BMI of 27 or greater and at least one weight-related condition.

This medication is intended to be used alongside a weight management program that includes a reduced-calorie diet and increased physical activity, highlighting its role as part of a comprehensive approach to weight loss.

Semaglutide 2.4 mg led to significant weight loss in adults with overweight/obesity, achieving a mean change of -15.7% for those on antidepressants compared to -0.2% for placebo, demonstrating its efficacy regardless of antidepressant use.

The safety profile of semaglutide was consistent with previous studies, showing a similar prevalence of adverse events between the semaglutide and placebo groups among participants taking antidepressants.

In a 12-week study involving 72 adults with type 2 diabetes, the multi-receptor agonist LY3437943 demonstrated a good safety profile, with gastrointestinal disorders being the most common side effects.

LY3437943 significantly reduced daily plasma glucose and HbA1c levels, as well as body weight, in a dose-dependent manner, supporting its potential for once-weekly dosing and further development in treating type 2 diabetes and obesity.
