OSE Immunotherapeutics present significant data on Selective Anti-SIRPa OSE-172 (Effi-DEM)

OSE Immunotherapeutics announced that the Company presented in oral session significant data on Selective Anti-SIRPa OSE-172 (Effi-DEM), at the “2nd Annual Advances in Immuno-Oncology Congress” in London on May 15, 2017.

OSE-172 (Effi-DEM) is a humanized monoclonal antibody targeting SIRPa, expressed on suppressive myeloid cells (Myeloid Derived Suppressor Cells, MDSC and Tumor Associated Macrophages, TAM) as well as effector myeloid cells (anti-tumoral macrophages) involved in the Tumor Micro-Environment. As a selective antagonist of SIRPa, OSE-172 promotes recruitment of effector over suppressive myeloid cells, in particular it inhibits M2 pro-tumorigenic macrophage cells and increases M1 anti-tumorigenic cells, whilst increasing effector memory CD8 T-cells resurrecting key immune defenses.

OSE-172 does not bind to red blood cells and platelets constituting a potential hematologic safety advantage.

“Our myeloid checkpoint inhibitor OSE -172demonstrates its strong impacton the Tumor Micro-Environment beyond myeloid cells, tackling cancer through a specific blockade of SIRPa,” said Nicolas Poirier, Chief Scientific Officer of OSE Immunotherapeutics.
