With the site activation process largely complete, the Company is focused on accelerating enrollment and generating randomized clinical data evaluating the contribution of pelareorep to the current standard-of-care regimen.<\/p>\n<p align=\"justify\">REO 033 is a randomized controlled study evaluating pelareorep in combination with folinic acid, fluorouracil and irinotecan (\u201cFOLFIRI\u201d) and bevacizumab versus FOLFIRI and bevacizumab in patients with second-line RAS-mutant MSS mCRC. Part A is expected to enroll approximately 60 patients randomized between the two treatment arms, with objective response rate (\u201cORR\u201d) as the primary endpoint, and progression-free survival (\u201cPFS\u201d), overall survival (\u201cOS\u201d), safety, and biomarker analyses among the additional endpoints.<\/p>\n<p align=\"justify\">\u201cWe are seeing strong momentum in REO 033 now that substantially all of our planned sites are open and multiple patients are on study,\u201d said John McAdory, Chief Operating Officer of Oncolytics. \u201cGiven the current pace of enrollment, we expect to have the ability to report interim data from Part A by year-end, based on the number of evaluable patients enrolled by the end of October. Importantly, with site activation substantially behind us, our focus is now squarely on enrollment, execution, and generating the randomized clinical data that can inform the next stage of the program.\u201d<\/p>\n<p align=\"justify\">\n        <strong>REO 033 Builds on Encouraging REO 022 Clinical Data<\/strong>\n      <\/p>\n<p align=\"justify\">REO 033 was designed to prospectively evaluate the efficacy signals previously observed in REO 022 in a randomized setting.

Pelareorep has demonstrated encouraging results in multiple first-line pancreatic cancer studies, two randomized Phase 2 studies in metastatic breast cancer, and early-phase studies in anal and colorectal cancer. It is designed to induce anti-cancer immune responses by converting immunologically inactive tumors to active through the activation of innate and adaptive immune responses.<\/p>\n<p align=\"justify\">The Company is advancing pelareorep in combination with chemotherapy and\/or checkpoint inhibitors in metastatic gastrointestinal cancers, where pelareorep has received Fast Track designation from the FDA for colorectal, anal, and pancreatic cancer.
