Pretzel Therapeutics

Our mission is to develop groundbreaking therapies to reverse mitochondrial dysfunction by leveraging a deep mechanistic understanding of mitochondrial biology. Mitochondria are essential energy-converting cellular organelles found in nearly every cell type throughout the body. Dysfunctional mitochondria are involved in more than 50 diseases. The most severe of these are broadly termed mitochondrial diseases, a group of rare genetic conditions which affect individuals of all ages. Mitochondrial dysfunction also plays an important role in more common diseases, including aging-related disorders. At Pretzel, we are developing first-in-class therapeutics that can address mitochondrial dysfunction at its roots. By taking aim at the genetic drivers of mitochondrial dysfunction, we believe our approach could be effective across a wide range of diseases which lack meaningful treatment options today.
