Oncolytics Biotech® Inc. (NASDAQ:ONCY) ("Oncolytics" or the "Company"), a clinical-stage immunotherapy company developing pelareorep, today announced positive preclinical results evaluating pelareorep in combination with a pan-RAS inhibitor in a RAS-driven colorectal cancer model.

During the initial treatment period, when pelareorep was administered every other day, pelareorep, the pan-RAS inhibitor and the combination each reduced tumor growth compared to the control. The greatest tumor reductions were observed in the RAS inhibitor and combination groups, demonstrating that pelareorep activity was maintained in the presence of RAS inhibition without evidence of antagonism between the two therapies.
