These findings provide strong biological support for pursuing pelareorep as a precision immunotherapy capable of addressing a patient population that rarely benefits from checkpoint inhibitors or other immunotherapies. A complete analysis of the translational data will be presented at an upcoming medical meeting.</font></div><div style="text-align:justify"><font><br></font></div><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',serif;font-size:11pt;font-weight:400;line-height:120%">&#8220;Colorectal cancer is the core of our emerging GI tumor platform strategy for pelareorep, with a projected total addressable market of $20 billion by 2033,&#8221;</font><font style="color:#000000;font-family:'Times New Roman',serif;font-size:7.15pt;font-weight:400;line-height:120%;position:relative;top:-3.85pt;vertical-align:baseline">3</font><font style="color:#000000;font-family:'Times New Roman',serif;font-size:11pt;font-weight:400;line-height:120%"> said Jared Kelly, Chief Executive Officer of Oncolytics Biotech. &#8220;Pelareorep has clearly demonstrated the potential to become a transformational new treatment option in this underserved setting.

Achieving a 33% ORR in KRAS-mutant MSS colorectal cancer is highly unusual in this setting and warrants immediate further study. The translational findings strengthen the mechanistic rationale behind the clinical activity we&#8217;re observing.

The planned study is intended to confirm pelareorep&#8217;s potential to significantly outperform the current standard-of-care in a controlled setting and establish a new treatment paradigm for KRAS-mutant colorectal cancer. By sponsoring the study instead of pursuing an investigator-sponsored trial, Oncolytics will be able to provide an appropriate level of analytical rigor to support regulatory submissions that could lead to an approval in this indication. Additionally, the Company will have full control over data from the study and will be able to update investors, potential partners, and other stakeholders at its discretion. This change reflects the Company&#8217;s heightened interest in and focus on mCRC and pelareorep&#8217;s potential as a platform gastrointestinal immunotherapeutic agent.</font></div><div style="text-align:justify"><font><br></font></div><div style="text-align:justify"><font style="color:#000000;font-family:'Times New Roman',serif;font-size:11pt;font-weight:400;line-height:120%">References&#58;</font></div><div style="padding-left:36pt;text-align:justify;text-indent:-18pt"><font style="color:#000000;font-family:'Times New Roman',serif;font-size:11pt;font-weight:400;line-height:120%">1.</font><font style="color:#000000;font-family:'Times New Roman',serif;font-size:11pt;font-weight:400;line-height:120%;padding-left:9.75pt">Bennouna J.
