Intellectual property update confirms pelareorep's unique manufacturing process and scalability Previously filed method-of-use patent application expected to provide protection into 2046 Additional patent filings planned in 2026 to further expand the pelareorep intellectual property estate SAN DIEGO, June 16, 2026 (GLOBE NEWSWIRE) -- Oncolytics Biotech® Inc. (Nasdaq: ONCY) (“Oncolytics” or the “Company”), a clinical-stage company developing pelareorep, an investigational, systemically active immunotherapy that promotes potentially protective immune responses, including the upregulation of key inflammatory cytokines resulting in the formation of tertiary lymphoid structures and the expansion of tumor-infiltrating lymphocytes, today announced that the United States Patent and Trademark Office (“USPTO”) has issued a new patent broadly protecting the Company's proprietary manufacturing process for pelareorep. The newly issued patent covers key aspects of the methods used to manufacture pelareorep and is expected to provide intellectual property protection into 2044.

SAN DIEGO, June 01, 2026 (GLOBE NEWSWIRE) -- Oncolytics Biotech® Inc. (Nasdaq: ONCY) (“Oncolytics” or the “Company”), a clinical-stage company developing pelareorep, today announced initial data from a preclinical study evaluating pelareorep in combination with RAS inhibitor modalities in a solid tumor model, which demonstrate evidence of greater anti-tumor activity in combination than with the individual approaches alone. Pelareorep is an investigational, systemically active immunotherapy that promotes potentially protective immune responses, including the upregulation of key inflammatory cytokines resulting in the formation of tertiary lymphoid structures and the expansion of tumor-infiltrating lymphocytes.
