• Initiates Randomized Phase 2 Study

  Oncolytics Biotech launched the REO 033 study, a randomized Phase 2 trial evaluating pelareorep in second-line RAS-mutant microsatellite stable metastatic colorectal cancer patients.

• Aims to Confirm Strong Prior Efficacy

  The study is designed to confirm compelling efficacy data from the previous REO 022 study, which showed significantly improved median overall survival, progression-free survival, and objective response rates compared to standard-of-care.

• Fast Track Designation Received

  This study follows the recent Fast Track Designation granted by the FDA for pelareorep in 2L KRAS-mutant, MSS mCRC, underscoring the drug's potential in this indication.

• Preliminary Data Expected by Year-End

  The company anticipates initiating the first study site later this month and expects to provide preliminary data from the REO 033 trial by the end of 2026.
