CAMBRIDGE, Mass., March 30, 2017 (GLOBE NEWSWIRE) -- Proteostasis Therapeutics, Inc. (NASDAQ:PTI), a biopharmaceutical company developing small molecule therapeutics to treat diseases caused by dysfunctional protein processing such as cystic fibrosis (CF), today announced financial results for the fourth quarter and year ended December 31, 2016 and provided a corporate update.
“Today, CFTR modulator triple combinations represent the greatest promise for delivering maximum efficacy for the vast majority of CF patients and have become the central focus in a rapidly evolving clinical landscape,” said Meenu Chhabra, president and chief executive officer of Proteostasis Therapeutics. “Preclinical data suggest that Proteostasis’ proprietary triple combination solution of an amplifier (PTI-428), a corrector (PTI-801) and a potentiator (PTI-808) has the potential to demonstrate best-in-class efficacy because it is the only triple combination that addresses separate aspects of CFTR dysfunction in an entirely orthogonal manner from protein synthesis to processing to function. To realize this potential in an increasingly crowded clinical environment, we are pivoting our PTI-428 program to ex-U.S. clinical sites, initiating the clinical development of PTI-801 in regions where Orkambi is approved and expect to file an IND for PTI-808 in the second quarter. Our goal is to establish efficacy for PTI-428 and PTI-801 in an Orkambi population, and thus start the proof of concept study for our triple combination by the end of the year.”
