Agenus BOT+BAL meets primary endpoint in Phase 2 MSS colon cancer trial
- Agenus announced published Phase 2 UNICORN results in Nature Medicine evaluating preoperative botensilimab plus balstilimab in resectable, locally advanced colon cancer.
- The combination produced deep tumor responses, including complete tumor clearance in some patients with microsatellite-stable disease, which historically resisted conventional immunotherapy.
- No combination-treated patients experienced cancer recurrence by the February 9, 2026, data cutoff; all trial participants underwent surgery.
- The findings support the planned randomized Phase 3 ROBBIN trial comparing the combination followed by standard care against standard care alone.
