Oncolytics Biotech Reports Positive Preclinical Data for Pelareorep in RAS-Targeted Cancer Combinations

  • Oncolytics Biotech reported initial preclinical data showing enhanced anti-tumor activity when pelareorep was combined with RAS inhibitor modalities in solid tumor models.
  • The company plans additional studies in pancreatic ductal adenocarcinoma (PDAC) and colorectal cancer (CRC) models to evaluate immune activation and tumor response durability.
  • Full results from the initial preclinical studies are expected to be presented in the fall or winter of 2026.
  • Pelareorep has received Fast Track designation from the FDA for colorectal and pancreatic cancer.

Oncolytics Biotech's preclinical data supports the potential of pelareorep as an immune-priming backbone for next-generation targeted therapies, particularly in RAS-mutated tumors like pancreatic and colorectal cancers. This aligns with broader industry trends toward combination immunotherapies to overcome intrinsic immune resistance and therapeutic resistance in difficult-to-treat cancers. The company's focus on these high-unmet-need areas could position pelareorep as a key player in the evolving landscape of cancer treatment.
