Powering Cells in People with Rare Mitochondrial Diseases

Primary mitochondrial myopathies are a group of rare, often life-threatening disorders caused by genetic mutations that affect the energy needs of skeletal muscles and can impact the ability to walk, lift, or do other everyday activities. High energy tissues like the heart, brain, and muscle are most affected by these disorders. Currently, there are no approved drugs to treat people with these conditions. Reneo Pharmaceuticals is developing an experimental therapy that works by increasing the transcription of genes involved in mitochondrial function, increasing fatty acid oxidation, and promoting the formation of new mitochondria. We spoke to Greg Flesher, president and CEO of Reneo, about mitochondrial myopathies, the company’s efforts to develop an experimental therapy to treat these conditions, and how it works.
