Agenus Presents BOT and BAL Combination Therapy Data at Cancer Research Meeting
Agenus announced data from an investigator-initiated Phase II trial at Memorial Sloan Kettering Cancer Center, investigating botensilimab (BOT) and balstilimab (BAL) in combination with agenT-797, MiNK's allo-iNKT cell therapy, ramucirumab and paclitaxel in patients with advanced PD-1 refractory gastroesophageal adenocarcinoma. The data are being presented at the American Association for Cancer Research Annual Meeting, taking place April 17-22, 2026, in San Diego, CA. This Phase II trial, which is the first to combine BOT and BAL with agenT-797 in patients with gastroesophageal cancer who progressed after frontline therapy, was designed to explore the role of immune priming and treatment sequencing. Patients received induction with agenT-797 (alone or plus BOT/BAL) followed by the full combination regimen, or initiated the combination without induction, with longitudinal biomarker sampling throughout. In this study, the regimen delivered a 77% DCR with long-term survival beyond 20 months in a subset, and the induction arm showed meaningful gains in PFS (6.9 vs. 3.5 months; HR 0.19; p=0.015) and OS (9.5 vs. 5.2 months), with 43% of induction-treated patients alive at both 12 and 18 months-underscoring that durability and survival may be the most clinically relevant endpoints in this PD-1 refractory population.

About the author

- Significant Disease Control: A clinical trial for gastroesophageal cancer combining botensilimab (BOT), balstilimab (BAL), and agenT-797 demonstrated a 77% disease control rate, with long-term survival exceeding 20 months in a subset of heavily pretreated patients, indicating the potential of this combination therapy in refractory cases.
- Improved Survival Rates: Patients receiving induction therapy had a median progression-free survival (PFS) of 6.9 months compared to 3.5 months for those without induction, with a hazard ratio (HR) of 0.19 and a p-value of 0.015, underscoring the importance of immune activation and treatment sequencing.
- Enhanced Long-Term Survival: In the induction cohort, 43% of patients were alive at both 12 and 18 months, compared to only 20% and 0% in the non-induction group, highlighting the effectiveness of the induction strategy in improving long-term survival outcomes.
- Insights into Immune Mechanisms: The study revealed that the combination of BOT, BAL, and agenT-797 significantly promoted intratumoral T cell and dendritic cell infiltration, leading to the formation of organized tertiary lymphoid structures, providing crucial insights for further exploration of the biological basis of this therapy.
