Agenus Reports 51% of Patients Survive at Least 18 Months in BOT+BAL Colorectal Cancer Trial

By Public Technologies
  • Agenus reported durable survival with botensilimab and balstilimab in refractory colorectal cancer in Phase 1b findings already presented at SITC 2026.
  • The study involved heavily pretreated patients with microsatellite-stable metastatic disease without active liver metastases; some long-term survivors remained off all cancer treatment.
  • Long-term survival was not limited to favorable clinical profiles; fewer prior treatments were associated with better survival outcomes.
  • The findings support earlier treatment evaluation, including the Phase 3 ROBBIN strategy testing the combination before surgery in high-risk colon cancer.
  • No treatment-related deaths occurred; immune-mediated diarrhea or colitis resolved in nearly all affected long-term survivors.
