Oncolytics Highlights Pelareorep Preclinical Findings In Hepatocellular Carcinoma
Oncolytics Biotech (ONCY) reported preclinical findings in PNAS showing pelareorep treatment may alter the tumor microenvironment in liver cancer, increasing PD-L1 and ICOSL levels, and CD8+ T-cell density. The company noted liver cancer is not a target indication but is studying pelareorep in colorectal cancer with an interim update expected by year-end 2026. ONCY stock closed at $0.67, down 2.05% in premarket.
