About Proteostasis Therapeutics, Inc.

Proteostasis Therapeutics, Inc. is a biopharmaceutical company dedicated to the discovery of groundbreaking therapies to treat diseases caused by dysfunctional protein processing, such as cystic fibrosis (CF). Headquartered in Cambridge, MA, the Proteostasis Therapeutics team focuses on identifying therapies that modulate the proteostasis imbalance in cells and restore protein function. Proteostasis Therapeutics is currently enrolling eligible adults with CF to participate in its Phase 1 clinical trials of PTI-428. PTI-428 is a unique modulator of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein, called an amplifier, that when used in combination with existing treatments and therapies has shown a consistent positive effect on CFTR protein activity in vitro in pre-clinical studies. In addition to its multiple programs in cystic fibrosis, Proteostasis Therapeutics has formed collaborations with Biogen to research and identify therapeutic candidates for neurodegenerative disease and with Astellas Pharma, Inc. to research and identify therapies targeting the Unfolded Protein Response (UPR) pathway.
