Reneo Pharmaceuticals, Inc. is a pharmaceutical company. The Company is focused on the development and commercialization of therapies for patients with rare genetic mitochondrial diseases, which are often associated with the inability of mitochondria to produce adenosine triphosphate (ATP). The Company’s product candidate, mavodelpar, is a potent and selective agonist of the peroxisome proliferator-activated receptor delta (PPARd). Mavodelpar helps in increasing the transcription of genes involved in mitochondrial function and increases fatty acid oxidation (FAO) and may increase the production of new mitochondria. The Company is developing REN001 in the two rare genetic diseases that present with myopathy and have unmet medical needs: primary mitochondrial myopathies (PMM), and long-chain fatty acid oxidation disorders (LC-FAOD).
