Breakthrough Immunotherapy Combination Shows Promise Against Common Colorectal Cancer in Phase 1 Trial
- A phase 1 trial of 148 patients demonstrated that the combination of botensilimab and balstilimab immunotherapy drugs successfully treated microsatellite stable metastatic colorectal cancer, the most common form that has historically not responded to immunotherapy.
- The study found that 61% of patients experienced tumor shrinkage or stabilization after six months of treatment, marking the first time consistent and durable responses to immunotherapy have been reported in this difficult-to-treat patient population.
- The treatment was well-tolerated with common side effects including diarrhea and fatigue, and showed particular effectiveness in patients without liver metastases.
- Agenus Inc. is planning to seek FDA approval and has initiated a phase 3 clinical trial, potentially offering new hope for colorectal cancer patients who face limited treatment options.
