Proteostasis Therapeutics, Inc. is an innovative biopharmaceutical company committed to the discovery and development of novel therapeutics that treat diseases caused by an imbalance in the proteostasis network, a set of pathways that control protein biosynthesis, folding, trafficking and clearance. Our initial therapeutic focus is on cystic fibrosis, or CF, which is caused by defects in the cystic fibrosis transmembrane conductance regulator, or CFTR, protein and insufficient CFTR protein function. CF is an orphan disease that affects an estimated 70,000 to 100,000 patients worldwide, with the vast majority of affected individuals in the United States, Canada, Europe and Australia. CF is the most common fatal inherited disease in Caucasians, and there is presently no cure.
