Epirium Bio is a start-up pharmaceutical company that is developing a novel class of therapeutics that induces the formation of new mitochondria (mitochondrial biogenesis) and enhances mitochondrial function in response to metabolic demand. Chronic depletion of mitochondria, the principal source of cellular ATP, has been directly linked to the progression of heart failure, sarcopenia, and neurodegeneration. Epirium Bio is collaborating with numerous academic medical centers to advance novel drug candidates structurally based on a newly discovered human hormone that appears to fundamentally regulate mitochondrial density and function in all tissues. Epirium Bio believes that enhancing myocyte bioenergetics will comprise an innovative therapeutic approach complementary to currently available cardiovascular drugs. The company’s clinical development focus is the lethal cardiomyopathy associated with orphan diseases characterized by loss of mitochondria in muscle and heart, resulting in heart failure that is poorly responsive to current medical interventions. Initial clinical trials are directed toward Duchenne muscular dystrophy and Friedreich’s ataxia.
