Pieris Pharmaceuticals, Inc. (PIRS)

PIRS Investigation 

Bronstein, Gewirtz & Grossman, LLC is investigating potential claims on behalf of purchasers of Pieris Pharmaceuticals, Inc. ("Pieris" or the “Company”) (NASDAQ: PIRS). The investigation concerns whether Pieris and certain of its officers and/or directors have violated federal securities laws.


On July 20, 2020, Pieris announced that the U.S. Food and Drug Administration (“FDA” or the “Agency”) had placed a partial clinical hold on the Company’s Phase 1 studies of its PRS-343 product “while Pieris conducts an additional in-use and compatibility study requested by the Agency.”  Pieris specifically stated that “[t]he partial hold follows discussions with FDA regarding the Company's in-use study supporting the technical setup for clinical administration of PRS-343” and that the “FDA has requested that Pieris conduct an additional in-use and compatibility study of PRS-343 with various infusion materials under specific conditions to confirm suitability of PRS-343 for administration in clinical settings.”  On this news, Pieris’s stock price fell sharply during intraday trading on July 21, 2010, damaging investors.
