• Study will highlight novel iNKT cell-based combinations in checkpoint-refractory disease
• Data expected to inform immune modulation, treatment sequencing strategy, and clinical durability of response

NEW YORK, April 03, 2026 (GLOBE NEWSWIRE) -- MiNK Therapeutics, Inc. (NASDAQ: INKT), a clinical-stage biopharmaceutical company pioneering allogeneic invariant natural killer T (allo-iNKT) cell therapies to restore immune balance and treat immune-mediated diseases and cancer, today announced that data from an investigator-initiated Phase II trial at Memorial Sloan Kettering Cancer Center, evaluating agent-797, MiNK’s allo-iNKT cell therapy, in combination with botensilimab (BOT) and balstilimab (BAL), will be presented at the American Association for Cancer Research (AACR) Annual Meeting, taking place April 17-22, 2026, in San Diego, CA.

The study evaluates this multi-mechanistic immunotherapy regimen in patients with PD-1 refractory gastroesophageal cancer (GEC), an area of high unmet need where resistance to checkpoint inhibition remains a significant clinical challenge.

“This study represents one of the first clinical evaluations of an iNKT cell therapy combined with dual checkpoint modulation in gastroesophageal cancer and marks an important step in understanding how to re-engage the immune system in patients who have progressed on prior checkpoint therapy,” said Jennifer Buell, Ph.D., President and CEO of MiNK Therapeutics.

“These data build on the immune-modulating findings we reported last year and extend them into the clinical setting. agenT-797 is designed to bridge innate and adaptive immunity as an immune orchestrator, with the potential to reprogram the tumor microenvironment and restore immune responsiveness. We believe these data will provide important insights into how immune reprogramming and treatment sequencing can drive more durable outcomes in refractory cancers and inform the next generation of combination strategies.”

About agenT-797

AgenT-797 is an allogeneic invariant natural killer T (iNKT) cell therapy that harnesses the dual power of innate and adaptive immunity. iNKTs function as “master regulators,” combining the cytotoxic capabilities of NK cells with T-cell–like antigen recognition and memory. This unique biology enables a robust, pathogen-agnostic immune response that can be directed against hard-to-treat tumors. Manufactured by MiNK Therapeutics in Lexington, MA, agenT-797 is a scalable, off-the-shelf product designed to provide accessible, transformative treatment options. In clinical trials, agenT-797 can bolster peripheral memory T-cell activation, enhance tumor infiltration, and potentially improve outcomes for patients with solid cancers (Cytryn et al. AACR IO 2024, Oncogene. 2024) and to combat inflammation in critically ill patients with severe respiratory pathology (Nature Communications. 2024).
