Oncolytics Biotech(r) Reports First Quarter 2023 Financial Results and Operational Highlights.

SAN DIEGO, Calif. and CALGARY, AB: Oncolytics Biotech(r) Inc. (NASDAQ: ONCY) (TSX: ONC) today announced recent operational highlights and financial results for the first quarter ended March 31, 2023. All dollar amounts are expressed in Canadian currency unless otherwise noted.

"Our core programs in breast and pancreatic cancer are moving towards registrational studies with compelling clinical data and important milestones expected this year," said Dr. Matt Coffey, President and Chief Executive Officer. "The first of these milestones will come later this month when we report data from BRACELET-1, a randomized phase 2 trial expected to inform the design of a subsequent pivotal registrational study in HR+/HER2- metastatic breast cancer. Stakeholders across the breast cancer community have demonstrated a keen interest in this readout, which will add to a dataset that already includes statistically significant phase 2 results showing pelareorep's ability to drive a robust overall survival benefit in this indication. Notably, the BRACELET-1 abstract was selected for an oral presentation at the upcoming ASCO meeting, providing a highly prestigious venue to discuss the results with potential partners and the clinical community."

Dr. Coffey continued, "Looking into the second half of 2023, we expect to report updated results from GOBLET's first-line pancreatic cancer cohort and provide guidance on the optimal registration paths for our breast and pancreatic cancer programs. With these programs both targeting large markets with significant clinical unmet needs and supported by robust clinical proof-of-concept data, we believe confirming their paths towards approval will represent important value-creating events and substantially de-risk and maintain pelareorep's development pathway."

First Quarter and Subsequent Highlights

Breast Cancer Program

BRACELET-1 data to be shared in an oral presentation at the ASCO Annual Meeting

BRACELET-1 is designed to confirm and expand upon Oncolytics' prior positive clinical results for pelareorep in HR+/HER2- metastatic breast cancer and inform the design of a subsequent registrational study. These prior data include phase 1 results demonstrating pelareorep's single-agent activity, as well as randomized phase 2 data that showed a statistically significant near doubling of median overall survival in patients treated with pelareorep combined with paclitaxel compared to those treated with paclitaxel monotherapy...
