Durability Metrics Outpace Historical Benchmarks

Oncolytics Biotech ( ONCY ) announced that pelareorep demonstrated a 19.5-month median duration of response in second-line KRAS-mutant microsatellite-stable colorectal cancer patients, significantly outperforming historical benchmarks of four to six months.

The company is actively engaging with the FDA to explore a potential accelerated approval pathway based on these encouraging results.

Additional data from the study include an objective response rate of 33% for patients receiving pelareorep, bevacizumab, and FOLFIRI, tripling the 6%-11% for the standard of care.

CEO Highlights Durability Signal and Approval Pathway

“We believe these data demonstrate a compelling durability signal for pelareorep in colorectal cancer,” said Jared Kelly, CEO of Oncolytics.

“A 19.5-month median duration of response in second-line patients — representing a three- to four-fold improvement over historical expectations — highlights pelareorep’s potential to deliver sustained benefit in a population with few effective options. We believe these results support a path toward accelerated approval in second-line RAS-mutant MSS metastatic colorectal cancer, and we are actively engaging with the FDA to align on a regulatory strategy leveraging our ongoing randomized study.”

In April, Oncolytics Biotech ( ONCY ) announced a Type C meeting with the U.S. Food and Drug Administration (FDA) resulted in alignment on the design of a pivotal clinical study to support approval of pelareorep for unresectable metastatic squamous cell carcinoma of the anal canal.

ONCY Stock Price Activity: Oncolytics Biotech ( ONCY ) shares were up 4.53% at 91 cents at the time of publication on Monday, according to Benzinga Pro data.
