Elamipretide is primarily researched for its potential therapeutic applications in mitochondrial diseases. It is being studied for its ability to target and protect mitochondrial function, particularly in conditions like Barth syndrome, primary mitochondrial myopathy, and Leber's hereditary optic neuropathy. By stabilizing mitochondrial membranes and reducing oxidative stress, it aims to improve cellular energy production and overall tissue function. Clinical trials are ongoing to evaluate its efficacy in treating these disorders, offering hope for patients with limited treatment options. Additionally, its role in neurodegenerative diseases and heart failure is being explored, as mitochondrial dysfunction is a common factor in these conditions.
