Apitegromab for Obesity
(EMBRAZE Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a drug called apitegromab to determine if it aids weight loss in individuals who are overweight or obese when combined with a GLP-1 receptor agonist. Participants will receive either apitegromab with this treatment or a placebo (a substance resembling the drug but without active ingredients) alongside the treatment. The goal is to determine if apitegromab enhances the effectiveness of the weight loss treatment. Individuals with stable body weight, a BMI of 30 or higher, or a BMI of 27 or higher with weight-related health issues, and no major chronic diseases may be suitable for this trial. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, offering a chance to contribute to significant findings in weight loss therapy.
Do I need to stop my current medications for this trial?
The trial information does not specify whether you need to stop taking your current medications. However, since the study involves apitegromab as an additional therapy to GLP-1 agonist therapy, it might be best to discuss your current medications with the trial team.
Is there any evidence suggesting that apitegromab is likely to be safe for humans?
Research has shown that apitegromab, currently under study for obesity, holds promise in other areas as well. For instance, in studies involving individuals with spinal muscular atrophy (SMA), those treated with apitegromab demonstrated improved movement abilities over 48 months, suggesting it is well-tolerated over long periods.
In another study, apitegromab combined with tirzepatide helped patients maintain their lean muscle mass during treatment, indicating further evidence of its safety and tolerability.
While these results are encouraging, it is important to remember that all medications can have side effects. Ongoing research aims to better understand these effects. Always consult a healthcare provider before joining a study.12345Why do researchers think this study treatment might be promising for obesity?
Unlike the standard obesity treatments, which often focus on reducing appetite or calorie absorption, Apitegromab offers a novel approach by targeting myostatin, a protein that limits muscle growth. By inhibiting myostatin, Apitegromab may help increase muscle mass, potentially boosting metabolism and aiding weight loss. Researchers are excited about this treatment because it could offer a dual benefit: not only helping with weight reduction but also improving overall muscle health, which is crucial for long-term weight management.
What evidence suggests that apitegromab might be an effective treatment for obesity?
Research shows that apitegromab may help preserve muscle while supporting weight loss. In this trial, participants in Cohort 1 will receive apitegromab combined with an incretin mimetic. Previous studies have shown that patients using apitegromab with tirzepatide retained 54.9% more muscle, approximately 4.2 pounds, compared to those using tirzepatide alone. This combination could help maintain muscle while losing weight. Additionally, total weight loss was nearly the same between those on apitegromab-tirzepatide and tirzepatide alone, with only a small difference of about 1.1%. These findings suggest that apitegromab might effectively manage weight by preserving muscle mass.12678
