- Significant Clinical Response: Among 113 patients treated with BOT+BAL, the AI-identified subgroup exhibited a 64% response rate compared to just 9% in the remaining cohort, highlighting TARIO-2's potential in identifying patients likely to benefit from treatment.
- Improved Survival Rates: In the MSS metastatic colorectal cancer cohort without active liver metastases, the AI-identified subgroup had a median overall survival not reached, with a hazard ratio of 0.18, indicating TARIO-2's significant predictive power for survival outcomes.
- Innovative Technology Application: The TARIO-2 model analyzes standard H&E pathology images to extract biologically relevant tumor microenvironment features, offering a patient stratification strategy that does not rely on complex tissue profiling, which could transform clinical practices.
- Future Validation Plans: Agenus is set to present these findings at the 2026 ASCO Annual Meeting, aiming to validate TARIO-2 as an image-based biomarker strategy for BOT+BAL, thereby advancing the clinical development of immunotherapy.

- Survival Rate Breakthrough: The fully enrolled 123-patient Phase 1b study demonstrated a median overall survival of 21.2 months and a three-year overall survival rate of 33% for the BOT+BAL combination, significantly surpassing the 10-14 months typical of conventional treatments, indicating potential advantages in refractory colorectal cancer patients.
- Good Tolerability: Extended safety follow-up revealed no new safety signals, with 98% resolution of immune-mediated diarrhea/colitis and no treatment-related deaths, suggesting that BOT+BAL has a favorable safety profile compared to traditional immunotherapies.
- Significant Treatment Effects: Among patients who had received at least three prior therapies, 21% achieved confirmed objective responses, and 17% were alive and off all systemic anticancer therapy at last follow-up, highlighting the durable efficacy of the combination.
- Clinically Meaningful Implications: These findings not only provide robust support for the use of BOT+BAL in refractory colorectal cancer but also lay the groundwork for the upcoming randomized Phase 3 BATTMAN trial, potentially reshaping treatment expectations in this field.

- Clinical Trial Results: Agenus' Phase 1b trial data reveals that in 19 patients with treatment-refractory hepatocellular carcinoma (HCC), the combination of BOT and BAL achieved an objective response rate of 17%, including one complete response and two partial responses, indicating potential efficacy in this challenging patient population.
- Survival Analysis: Among 18 efficacy-evaluable patients, the median overall survival was reported at 12.3 months, despite 47% of the cohort having ALBI grade 2 liver function, which typically indicates poorer prognosis, thus highlighting the potential of BOT and BAL in improving survival outcomes.
- Safety Assessment: The safety profile of BOT and BAL in HCC patients was consistent with prior studies, with 68% of patients experiencing immune-mediated adverse events and no treatment-related deaths, suggesting that the combination is manageable and suitable for further investigation.
- Future Research Directions: Investigators noted that the BOT and BAL combination demonstrated promising efficacy and manageable safety in post-immunotherapy HCC patients, supporting continued exploration in this area to assess its applicability in a broader patient population.
