Pieris Pharmaceuticals Presents Preclinical Data for GPC3/4-1BB Bispecific PRS-342 at the 2019 American Association for Cancer Research (AACR) Annual Meeting
BOSTON, MA / ACCESSWIRE / April 2, 2019 / 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 the presentation of preclinical data for PRS-342, a GPC3/4-1BB immuno-oncology bispecific drug candidate, at a poster session at the 2019 American Association for Cancer Research (AACR) Annual Meeting.
The poster, titled "Costimulatory T-cell engagement by PRS-342, a GPC3/4-1BB bispecific molecule, leads to activation of T cells and tumor growth inhibition in a HCC humanized mouse model," demonstrated that T-cell activation by PRS-342 led to NF-kB activation, increased production of IL-2 and dose-dependent cytolysis of GPC3-expressing tumor cells. PRS-342 also demonstrated a localized increase of tumor-infiltrating lymphocyte (TIL) levels in a humanized hepatocellular carcinoma (HCC) xenograft mouse model. The data presented suggest potent T-cell activation that is strictly dependent on the presence of GPC3-positive tumor cells. A copy of the poster presentation is available on the publications section of the Pieris website.
