Oncolytics Biotech Inc. (NASDAQ:ONCY) stock experienced a significant surge of 16.2% after the U.S. Food and Drug Administration (FDA) granted Fast Track Designation to its leading immunotherapy candidate, pelareorep. The designation is for its use in treating metastatic colorectal cancer.
The Fast Track status applies to pelareorep used in combination with bevacizumab and FOLFIRI for second-line treatment of patients with KRAS-mutant, microsatellite-stable metastatic colorectal cancer. This regulatory milestone follows promising clinical data where the therapy demonstrated a 33% objective response rate, substantially higher than the approximate 10% achieved with standard-of-care treatments.
This designation is a crucial validation for Oncolytics, signaling a potentially expedited path to market. The news prompted a sharp increase in investor confidence, reflected in the stock's double-digit jump. The therapy addresses a challenging cancer type within an estimated annual market of $3-5 billion. Furthermore, trial data showed the pelareorep combination significantly improved survival, with median overall survival at 27 months compared to 11.2 months with existing treatments.
With Fast Track status, Oncolytics gains more frequent communication with the FDA and eligibility for Accelerated Approval and Priority Review. The company plans to start a controlled clinical study in March, comparing standard therapy with the pelareorep combination. Interim data is expected by the end of 2026. This marks the second Fast Track Designation for pelareorep in gastrointestinal cancers, reinforcing its potential as a broad platform therapy.
Q: What is FDA Fast Track Designation?
A: It is a process designed to facilitate development and expedite the review of drugs to treat serious conditions and fill an unmet medical need.
Q: What is pelareorep?
A: Pelareorep is an investigational immunotherapy developed by Oncolytics Biotech designed to work in combination with other cancer therapies to improve patient outcomes.
Q: Why did Oncolytics (ONCY) stock increase sharply?
A: The stock surged 16.2% because the FDA's Fast Track Designation significantly de-risks and potentially shortens the development timeline for its key drug, boosting its commercial prospects.
