MiNK Reports Fourth Quarter and Year-End 2023 Results

• Launched and enrolling Phase 2 trial of allo-iNKTs with botensilimab/balstilimab and chemotherapy in second-line gastroesophageal cancers

• Announced collaboration with Immunoscape for development of TCR-based therapies
  
• Published clinical data in Nature Communications and Oncogene demonstrating clinical activity of allo-iNKTs, agenT-797, in solid tumors and severe acute respiratory distress
  

NEW YORK, March 21, 2024 (GLOBE NEWSWIRE) --  MiNK Therapeutics, Inc. (NASDAQ: INKT), a clinical-stage biopharmaceutical company pioneering the discovery, development, and commercialization of allogeneic, off-the-shelf, invariant natural killer T (iNKT) cell therapies to treat cancer and other immune-mediated diseases, today announced results for the fourth quarter and full-year 2023. MiNK executives will host a conference call and webcast at 8:30 a.m. ET to discuss the results and to provide a corporate update.

“In 2023, MiNK made significant strides in advancing our allogeneic iNKT cell programs, contributing to a growing body of clinical data that underscores the unique advantages of iNKTs and their pivotal role in immunity,” said Dr. Jennifer Buell, Chief Executive Officer and President at MiNK. “We expanded the scope of our pipeline, solidifying key partnerships such as our research agreement with ImmunoScape. As we move forward, our primary focus remains on advancing our lead program, agenT-797, particularly in indications where we have observed promising proof-of-concept data. We are pleased to announce the progression of this program into a Phase 2 study in gastroesophageal cancers and we anticipate sharing initial trial data later this year.”

2023 Highlights

AgenT-797 in Solid Tumors

• Announced the launch of a Phase 2 investigator-sponsored trial in gastroesophageal cancers, led by Dr. Yelena Janjigian, Chief of Gastrointestinal Oncology Service at Memorial Sloan Kettering Cancer Center (NCT06251973).
• Supported by Stand Up To Cancer, this trial is actively enrolling and evaluating the combination of agenT-797 (allo-iNKTs), Agenus' botensilimab (a novel Fc-enhanced CTLA-4 inhibitor), along with balstilimab (anti-PD-1), ramucirumab, and paclitaxel.
• These data aim to provide invaluable insights into the clinical activity and development pathway for this difficult disease, where there are currently no curative therapies available.
  

AgenT-797 in Acute Respiratory Distress (ARDS)

• MiNK's Phase 1/2 study in patients with moderate to severe ARDS was published in Nature Communications. The study reports survival rates exceeding 70% among patients on mechanical ventilation and surpassing 80% among those receiving VV ECMO support. These results stand in stark contrast to the 10% survival rate observed in the in-hospital control during the same period.
• Moreover, demonstrating its immunologic properties, agenT-797 showcased a significant reduction in secondary bacterial and fungal infections, with an over 80% decrease in pneumonia cases within the highest dose cohort.
• Looking ahead, MiNK remains committed to addressing critical unmet needs in respiratory care. The company is poised to advance agenT-797 in patients with viral ARDS through a predominantly externally funded, large platform trial.
  

Research Programs

• MiNK entered into a collaboration agreement with Immunoscape, aimed to accelerate the development of TCR-based therapies against novel targets in T cells, iNKT cells, and other modalities for solid tumor cancers.
• MiNK-215 preclinical efficacy was presented at the American Society of Gene and Cell Therapy (ASGCT) 2023 annual meeting that showed MiNK-215’s activity in non-small cell lung cancer (NSCLC) models.
• MiNK-215 IND enabling activities are underway to support clinical advancement; supportive financing discussions are underway.
  

Manufacturing Progress

• MiNK continued internal manufacturing of its allogeneic iNKT cells, through an FDA cleared, automated and closed-system process. MiNK is supplying product for its ongoing clinical trials.
  

Financial Results

We ended the year with a cash balance of $3.4 million. Since year-end we received $5 million under our convertible note agreement with Agenus Inc. Cash used in operations for the three and twelve months ended December 31, 2023, was $3.0 million, and $15.8 million, respectively, compared to $4.4 million and $18.9 million for the same periods in 2022.
