Trial Summary

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.

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.12345

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.12567

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.168910

Eligibility Criteria

This trial is for adults with obesity, defined as having a BMI ≥30 kg/m², or overweight individuals (BMI ≥27 kg/m² and <30 kg/m²) with weight-related health issues like high blood pressure on medication, cholesterol problems on drugs, heart disease, or sleep apnea. Participants should have maintained their body weight within a 5% range in the past 3 months.

Your body weight has not changed by more than 5% in the past 3 months before joining the study.
My BMI is between 27 and 30, and I have a weight-related health issue.
You have a BMI of 30 or higher.

Findings from Research

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.
The effect of semaglutide 2.4 mg once weekly on energy intake, appetite, control of eating, and gastric emptying in adults with obesity.Friedrichsen, M., Breitschaft, A., Tadayon, S., et al.[2021]
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.

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.
