## **Item 8.01 Other Events.** 
On July 11, 2005, MiNK Therapeutics, Inc. ("MiNK" or the "Company"), a clinical-stage biopharmaceutical company pioneering allogeneic, off-the-shelf invariant natural killer T (iNKT) cell therapies, announced the publication of *another* landmark case in Nature's *Oncogene* describing a complete and durable remission in a patient with metastatic, treatment-refractory testicular cancer, following treatment with agenT-797, MiNK's allogeneic iNKT cell therapy. The publication, titled *"Salvage therapy with allogeneic invariant natural killer T cells in a heavily pre-treated germ cell tumor,"* presents a patient case from MiNK's clinical trial (NCT05108623). The patient had progressed after multiple lines of therapy—including platinum-based chemotherapy, autologous stem cell transplant, and multiple immune checkpoint inhibitors (anti–PD-1, anti–CTLA-4, and anti–TIGIT)—and received a single infusion of agenT-797 alongside nivolumab. The patient achieved a complete clinical, radiologic, and biochemical remission, with no evidence of disease over two years later*.* Donor iNKT cells were detectable up to six months post-infusion, and treatment was well-tolerated with no cytokine release syndrome (CRS) or graft-versus-host disease (GVHD).

In addition, at the 2025 inaugural AACR Immuno-Oncology meeting, MiNK presented data from its Phase 2 trial in 2L gastric cancer, demonstrating immune activation, increased tumor infiltration, and early signals of tumor control in patients previously refractory to checkpoint inhibitors. Extended survival beyond 12 months was observed in several patients. In a separate peer-reviewed case report published in *Oncogene*, which described a patient with metastatic gastric cancer who achieved a 42% tumor reduction and more than nine months of progression-free survival following a single infusion of agenT-797 in combination with nivolumab.

The ongoing Phase 2 trial in gastric cancer (NCT06251973) is actively enrolling, with additional readouts expected in upcoming months.

**Forward-Looking Statements** 

This current report contains "forward-looking statements" within the meaning of the U.S. federal securities laws. Forward-looking statements can be identified by words such as "projects," "may," "will," "could," "would," "should," "believes," "expects," "anticipates," "estimates," "intends," "plans," "potential," "promise" or similar references to future periods. Forward-looking statements are statements that are not historical facts, nor assurances of future performance. Instead, they are based on the Company's current beliefs, expectations and assumptions regarding the future of its business, future plans, strategies, projections, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent risks and uncertainties, and actual results may differ materially from those set forth in the forward-looking statements. Important factors that could cause actual results to differ include, without limitation, the important risks detailed under the caption "Risk Factors" in the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2025 and its other filings with the Securities and Exchange Commission. Any forward-looking statement made by the Company in this current report is based only on information currently available and speaks only as of the date on which it is made. Except as required by applicable law, the Company expressly disclaims any obligation to publicly update any forward-looking statements, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise.
