Pioneering Mitochondrial Medicine

Tenaciously Pursuing Patient-Focused Solutions

At Mighty Therapeutics (formerly named Stealth BioTherapeutics), our work is personal. We apply deep biological understanding and development expertise to advance novel therapies, and we have the tenacity to progress them from discovery to approval to broad patient access.

We work with individuals living with mitochondrial disease and their families and healthcare providers to advance our shared goals of developing new therapies to improve care and quality of life. The voices of these individuals are mighty, and we hope to amplify and answer them. Together, we are working to expand what is possible for people living with the devasting effects of mitochondrial diseases.

Targeting Diseases and Disorders Associated with Mitochondrial Dysfunction

Mitochondrial dysfunction sits at the center of many diseases. We hope to change how it is treated.

Mighty Therapeutics targets mitochondrial dysfunction associated with rare genetic mitochondrial diseases and common diseases of aging. Our team partners with patients and advocacy organizations who can contextualize the burden of mitochondrial disease to inform our development priorities and help us raise awareness of the unmet need our programs seek to address.

Rare Genetic Mitochondrial Diseases

Rare genetic mitochondrial diseases such as Barth syndrome and [POLG-related] mitochondrial myopathy are associated with severe muscle weakness, which can impact all muscles in the body and lead to debilitating fatigue. Mighty Therapeutics developed the first, and currently only, approved therapy for Barth syndrome. There are currently no FDA or EMA approved treatments for POLG-related mitochondrial myopathy.

Ophthalmic Diseases

Dry age-related macular degeneration, or dry AMD, which is the leading cause of blindness among older adults in the developed world, is characterized by symptoms such as distorted or blurred vision, reduction in low luminance visual acuity and reduced overall visual acuity. We estimate that dry AMD impacts more than 10 million individuals in the United States. There is a significant unmet medical need for safe and less invasive therapies that permit earlier intervention in the trajectory of this progressively blinding disease to protect and potentially improve visual function.

Neurodegenerative Diseases

Some neurodegenerative diseases, including Parkinson’s disease, Leigh syndrome, and Friedreich’s ataxia, are linked to mitochondrial dysfunction. These diseases are progressive, debilitating, and affect multiple organ systems. Leigh syndrome is fatal, with most children passing away by age 3, and treatment is focused on palliative care. Treatment options for Parkinson’s disease and Friedreich’s ataxia are primarily limited to symptom management.
