Scientific Advisory Board to guide registration strategy for pelareorep across pancreatic, colorectal, and anal cancers

Oncolytics Biotech^® Inc. (Nasdaq: ONCY) (“Oncolytics” or the “Company”), a clinical-stage immunotherapy company developing pelareorep, today announced the formation of its Gastrointestinal (GI) Tumor Scientific Advisory Board (SAB), a group of leading oncology experts assembled to guide the Company’s clinical and regulatory strategy for developing pelareorep as a treatment for GI cancers.

Inaugural members of the SAB include Sanjay Goel, M.D., M.S., FASCO, Professor of Medicine and Director of the Phase I Program at Rutgers Cancer Institute of New Jersey; Deva Mahalingam, M.D., Ph.D., Professor of Medicine, GI oncologist and Director of the Developmental Therapeutics Program, Lurie Cancer Center at Northwestern University; and Dirk Arnold, M.D., Ph.D., FESMO, Principal Investigator of the GOBLET study, Professor of Medicine, and Director of Asklepios Tumorzentrum Hamburg, Germany. These three members have been the lead investigators in clinical trials evaluating pelareorep-based treatment regimens spanning colorectal cancer (CRC), pancreatic ductal adenocarcinoma (PDAC), and squamous cell anal carcinoma (SCAC). The SAB is expected to expand to six total members who will bring additional industry-leading clinical and regulatory expertise in these high-need GI cancer indications.

“Pelareorep has shown remarkable immune activation and durable efficacy across multiple GI tumor types,” said Dr. Sanjay Goel. “The opportunity to help guide Oncolytics as it moves toward registration studies is both scientifically and clinically exciting. I believe pelareorep has the potential to change how we approach immunotherapy in GI cancers.”

“As an investigator who has seen pelareorep’s clinical impact first-hand, I am impressed by its ability to synergize with checkpoint inhibitors and chemotherapy,” said Dr. Deva Mahalingam. “This advisory board represents a meaningful step toward positioning pelareorep as the first true platform immunotherapy in gastrointestinal tumors.”

“The clinical data emerging from the GOBLET study underscore pelareorep’s potential to improve outcomes across PDAC, CRC, and SCAC,” said Dr. Dirk Arnold. “I look forward to working with my colleagues and Oncolytics to help design and prioritize studies aimed at achieving regulatory approvals in these high-need indications.”

Dr. Thomas Heineman, Chief Medical Officer of Oncolytics Biotech, commented: “We are grateful to Drs. Goel, Mahalingam, and Arnold for joining our new GI SAB at this pivotal time for the Company. Their expertise in GI oncology and experience leading pivotal programs will be instrumental as we advance pelareorep towards registrational studies. The strength of this advisory board and the members’ enthusiasm for advancing the development of pelareorep reinforces our optimism about the role pelareorep can play in transforming the treatment landscape for patients with GI tumors.”

The Company stated that the SAB will play a critical role in shaping Oncolytics’ GI oncology development strategy, including the design of registration-enabling studies and potential pathways for accelerated approval in select tumor types. The SAB’s collective expertise will also support Oncolytics’ mission to establish pelareorep as the first platform immunotherapy in GI cancers.

About Oncolytics Biotech Inc.

Oncolytics is a clinical-stage biotechnology company developing pelareorep, an investigational intravenously delivered double-stranded RNA immunotherapeutic agent. 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 “cold” tumors “hot” through the activation of innate and adaptive immune responses.

The Company is advancing pelareorep in combination with chemotherapy and/or checkpoint inhibitors in metastatic pancreatic and breast cancers, of which both development programs have received Fast Track designation from the FDA, and other gastrointestinal tumors. Oncolytics is actively pursuing strategic partnerships to accelerate development and maximize commercial impact.
