10:32 AM EST - Oncolytics Biotech Inc. : Announced publication of an electronic poster at the CAR-TCR Summit Europe 2021 with data from a preclinical study evaluating pelareorep and chimeric antigen receptor (CAR) T cell combination therapy in solid tumors. Newly published results show that loading CAR T cells with pelareorep vastly improved their persistence and efficacy in a murine solid tumor model, in stark contrast to preclinical studies using intratumoral infection with the VSV oncolytic virus that weakened CAR T cells. Efficacy of pelareorep-loaded CAR T cell ("CAR/Pela") therapy was further enhanced by boosting mice 8 days later with a single intravenous dose of pelareorep ("pelareorep boost"), generating highly persistent CAR T cells, inhibition of recurrent tumor growth, and ultimately tumor cures. These synergistic immune effects were specific to pelareorep, as intravenous boosting with VSV did not augment CAR/Pela therapy or prevent the growth of recurrent tumors. "These very exciting data demonstrate pelareorep's ability to overcome major shortcomings of CAR T cells," said Dr. Matt Coffey , President and Chief Executive Officer. Oncolytics Biotech Inc.
