BOSTON, MA / ACCESSWIRE / January 19, 2021 / Pieris Pharmaceuticals, Inc. (NASDAQ:PIRS), a clinical-stage biotechnology company advancing novel biotherapeutics through its proprietary Anticalin^® technology platform for respiratory diseases, cancer, and other indications, today announced that the U.S. Food and Drug Administration (FDA) has lifted the previously announced partial clinical hold on the phase 1 studies of PRS-343. As previously guided, the Company intends to move into a proof-of-concept study of PRS-343 in gastroesophageal cancer.

'It has been rewarding to see the impact of PRS-343 on the lives of patients in these studies. Data continue to be encouraging, and the clinical benefit linked to single-agent activity that we have seen attests to the potential of this therapy and, more broadly, our localized 4-1BB agonism approach,' said Stephen S. Yoder, President and Chief Executive Officer of Pieris. 'We are excited to advance this program into the proof-of-concept phase and look forward to sharing more details about the study later this quarter.'
