What side effects are associated with this type of intervention?

Ultrasound contrast agents like Definity, used to enhance echocardiogram quality, are generally well-tolerated but can have side effects. Common side effects include headache, nausea, and dizziness. Rare but serious adverse effects may include hypersensitivity reactions, such as anaphylaxis, and cardiovascular events like arrhythmias. It is important for patients to discuss these potential risks with their healthcare provider before undergoing treatment.

What prior FDA approvals exist?

The FDA has approved several ultrasound contrast agents for the treatment of heart disease, specifically to improve the quality of echocardiograms by enhancing endocardial border delineation. One such agent is Definity (perflutren lipid microspheres), which is indicated for use in patients with suboptimal echocardiograms. Definity works by opacifying the left ventricular chamber, thereby improving the visualization of the left ventricular endocardial border. These agents are crucial in providing clearer images for better diagnosis and management of heart conditions.

What other types of research exist?

Promising alternatives to MVT-100 for enhancing echocardiogram quality include Definity (perflutren lipid microspheres), which is already established for this purpose. Additionally, advancements in T1 mapping and extracellular volume (ECV) fraction measurement using gadolinium-based contrast agents are emerging as effective methods for detailed cardiac imaging, particularly in conditions like cardiac amyloidosis. These techniques provide high diagnostic accuracy and can be useful in early disease detection and assessment.

Ultrasound Contrast Agents for Heart Imaging

Q: What is the mechanism of action of this treatment?

Ultrasound contrast agents like MVT-100 and Definity improve echocardiogram quality by enhancing the delineation of the left ventricular endocardial border, which is essential for accurate diagnosis and management of heart disease. This precise imaging allows for better assessment of cardiac function and structure, leading to more effective treatment plans. Other common treatments for heart disease include ACE inhibitors, beta-blockers, and statins, which lower blood pressure, reduce heart workload, and manage cholesterol levels, respectively. These treatments help prevent complications such as heart attacks and strokes, thereby improving patient outcomes.

Study Summary

This trial is evaluating the safety & efficacy of a new ultrasound contrast, MVT-100, in healthy volunteers to improve imaging of the heart's left ventricle. Patients receive either MVT-100 or Definity & have echocardiograms to measure safety & heart border delineation.

Who is the study for?

Healthy adults over 19, who can't have children or will use birth control, with normal blood counts and organ function. Excluded are those with recent heart attacks, unstable angina, severe heart failure, significant arrhythmias in the last six months, allergies to similar drugs or soy/egg products, participation in other trials within 30 days, conditions making lying flat for an hour difficult or certain lung issues.Check my eligibility

What is being tested?

The trial tests MVT-100 against Definity (both ultrasound contrast agents) in healthy volunteers using a single ascending dose method. Participants receive one of the two drugs and then undergo echocardiograms to assess safety and how well they help visualize the heart's inner lining during ultrasound.See study design

What are the potential side effects?

Potential side effects may include allergic reactions due to similarities with other compounds or ingredients like soy/egg products. Specific side effects aren't listed but would likely relate to infusion reactions such as discomfort at injection site or imaging-related complications.
