BOSTON, MA--(Marketwired - March 06, 2017) - Pieris Pharmaceuticals, Inc.
(NASDAQ: PIRS), a clinical-stage biotechnology company advancing novel biotherapeutics through its proprietary Anticalin®
technology platform, announced today that a set of ex vivo and in vivo data informing the trial design of a first-in-patient clinical trial for PRS-343, a first-in-class 4-1BB/HER2 bispecific, will be presented in a poster session at the 2017 Annual Meeting of the American Association for Cancer Research (AACR) to be held in Washington D.C., April 1 - 5, 2017. PRS-343 binds to 4-1BB (CD137) on T cells and HER2 on tumor cells, producing tumor-targeted immune activation.
Further details include:
PRS-343 is a bispecific monoclonal antibody/Anticalin fusion protein comprised of a HER2 tumor-targeting mAb genetically linked to a potent Anticalin specific for the immune costimulatory TNF family receptor 4-1BB (CD137). PRS-343 is being developed as the first 4-1BB based therapeutic to mediate the activation of tumor-specific T lymphocytes selectively within the tumor microenvironment (TME). 4-1BB is a potent costimulatory immunoreceptor and an established marker for tumor-specific infiltrating T lymphocytes (TILs), and is, therefore, an attractive target for cancer immunotherapy. In in vivo
preclinical tumor models, PRS-343 has demonstrated potent T lymphocyte activation localized to the TME of established HER2-positive tumors, indicating the potential for both enhanced safety and efficacy.
