MiNK Therapeutics Reports Second Quarter 2026 Financial Results and Reports Observations from Randomized Phase 2 Trial of agenT-797 in Acute Lung Injury

• First patients treated in randomized Phase 2 trial C-1300-02 were alive at Day 28, with improved oxygenation, resolution of ARDS with return to spontaneous breathing and liberation from vasopressor support
• Clinical recovery and biologic readouts moved in the same direction; serum and bronchoalveolar lavage analyses showed reduced inflammatory markers and biologic changes associated with immune recovery and tissue repair; no major serious adverse events were attributed to agenT-797
• Launched international paid named-patient access program established for physicians to request access to agenT-797, subject to per-patient regulatory authorization; building cross-border infrastructure and access
  
  

NEW YORK, Aug. 13, 2026 (GLOBE NEWSWIRE) -- MiNK Therapeutics, Inc. (NASDAQ: INKT), a clinical-stage biopharmaceutical company pioneering off-the-shelf allogeneic invariant natural killer T (iNKT) cell therapies for cancer and immune disorders, today reported financial results for the second quarter ended June 30, 2026, and provided an update on the clinical advancement of its lead candidate, agenT-797.

The second quarter marked MiNK's advancement to randomized clinical validation. The Company dosed its first patient in C-1300-02 within days of Ministry of Health authorization in Ukraine, and has since reported Day 28 observations in ventilated, critically ill patients treated in an active conflict environment - a pace made possible by a therapy that ships from inventory and requires no apheresis, patient-specific manufacturing, HLA matching, or lymphodepletion.

"We are building cell therapy for the real world-off the shelf, available from inventory, and deployable where patients receive care," said Jennifer Buell, Ph.D., President and Chief Executive Officer of MiNK Therapeutics. "This quarter, we put that mission into action. We moved agenT-797 into randomized Phase 2 evaluation and delivered it to mechanically ventilated patients within days of regulatory authorization-even in an active conflict environment. The initial clinical course and mechanistic readouts moved in the same direction over the same interval, consistent with the host-directed immune regulation our study was designed to evaluate. These observations are early, and we look forward to sharing additional data from the randomized trial in 2027."

"In parallel, we are building a new model for responsible access," Buell continued. "Our paid named-patient program enables physician-directed access, generates program support from product supplied, and establishes the cross-border infrastructure required to deliver agenT-797 beyond clinical trials. Together, these advances are moving cell therapy beyond specialized cancer centers and toward a readily available treatment that can reach patients when and where it is needed."

Second Quarter 2026 and Recent Highlights

Randomized Phase 2 Trial in Acute Lung Injury and ARDS

• Targets a high-mortality unmet need in critical care. Acute lung injury and ARDS remain among the most serious unresolved conditions in critical care, with mortality exceeding 40-50% and no approved therapies shown to reduce mortality.ⁱ Critically ill patients often deteriorate because severe lung injury can trigger broader immune dysfunction, including impaired pathogen control, infection susceptibility, and organ dysfunction.
• Randomized Phase 2 dosing initiated in May 2026. MiNK began dosing at First Lviv Territorial Medical Union in Lviv, Ukraine, in collaboration with UNBROKEN Ukraine, within days of receiving Ministry of Health authorization. C-1300-02 (NCT07615010) is evaluating agenT-797 plus standard of care versus placebo plus standard of care in adults with acute lung injury and moderate-to-severe hypoxemic respiratory failure meeting Global ARDS Definition criteria. The study is being conducted under an active U.S. IND.
• Initial Day 28 observations presented at the Military Health System Research Symposium (MHSRS). Dr. Terese C. Hammond, M.D., Head of Inflammatory and Pulmonary Diseases at MiNK, presented initial observations with co-authors from First Lviv Territorial Medical Union. The initial agenT-797-treated patients were alive and afebrile at Day 28, with improved oxygenation, resolution of ARDS with return to spontaneous breathing and liberation from vasopressor support. Microbiologic findings indicated control of baseline infections. Serum and bronchoalveolar lavage analyses showed reduced inflammatory markers and biologic changes associated with immune recovery, epithelial repair and pulmonary vascular recovery. No major serious adverse events were attributed to agenT-797 in these initial patients.
• U.S. expansion in progress. Enrollment continues in Lviv, and activation of U.S. clinical centers is underway. Additional data are expected in early 2027.
  
  

Paid International Named-Patient Access

• First paid international access program established. MiNK is collaborating with Orphan Drug Consulting (ODC) to support physician-initiated requests for agenT-797 for individually identified patients. The program expands access for patients with serious unmet medical need and provides MiNK with program revenue for product supplied. Each request is initiated by the treating physician and remains subject to case-by-case Brazilian regulatory authorization. The program does not represent a commercial launch or marketing authorization.
• Access, revenue and scalable international infrastructure. ODC supports local regulatory submissions, importation, logistics and pharmacovigilance. Product will be supplied on a paid, per-patient basis in accordance with applicable Brazilian access regulations. The program may result in non-promotional income to MiNK while establishing the operational infrastructure needed to support responsible access to agenT-797 in additional international markets.
  
  

Translational and Scientific Progress

• ATS 2026 and peer-reviewed publication (May 2026). Data presented at the American Thoracic Society International Conference and published concurrently in Clinical Immunology Communications showed pathogen suppression, lung immune restoration and activation of tissue-repair pathways following administration of agenT-797 and an IL-15 super agonist (N-803), in Coccidioides infection.
• ASGCT 2026 (May 2026). MiNK presented clinical evidence at the American Society for Gene and Cell Therapy Meeting that a single off-the-shelf iNKT-cell product manufactured from the same donor batch produced context-dependent immune activity-immune activation in cancer and anti-inflammatory activity in ARDS-without genetic engineering.
  
  

Financial Results

Cash and cash equivalents were $8.8 million as of June 30, 2026, compared with $9.5 million as of March 31, 2026, and $13.4 million as of December 31, 2025. Net loss for the second quarter of 2026 was $3.1 million, or $0.62 per share, compared with $4.2 million, or $1.06 per share, for the second quarter of 2025. For the six months ended June 30, 2026, net loss was $5.9 million, or $1.20 per share, compared with $7.0 million, or $1.76 per share, for the same period in 2025. The year-over-year improvement reflects continued expense discipline.

About the Paid Named-Patient Access Program in Brazil

Named-patient access refers to a physician-initiated request for an unregistered medicine for an individually identified patient, subject to authorization by the competent health authority. MiNK's program launched in Brazil and is administered in collaboration with Orphan Drug Consulting (ODC), which acts as MiNK's local partner for per-patient regulatory submissions, importation, cold-chain handling, and adverse event reporting. Access under the program is initiated only by a treating physician, who is responsible for determining whether use is medically appropriate for a particular patient, for obtaining informed consent, and for the clinical management and monitoring of that patient. MiNK does not identify, recruit, solicit, or select patients, does not compensate physicians for requesting the product, and does not conduct promotional activity with respect to agenT-797 in Brazil or in any other jurisdiction. agenT-797 has not been approved for marketing by the Brazilian Health Regulatory Agency (ANVISA), the U.S. Food and Drug Administration, or any other regulatory authority, and its safety and efficacy have not been established. Availability under the program does not imply that agenT-797 is safe or effective for any use, and the program is not a commercial launch. The program is separate from, and is not a substitute for, participation in MiNK's clinical trials; patients who may be eligible for C-1300-02 or another MiNK-sponsored study will be directed to those studies.

Forward-Looking Statements

This press release contains forward-looking statements within the meaning of the federal securities laws, including statements regarding the therapeutic potential, safety, clinical benefit, and development plans for agenT-797 and MiNK's other iNKT-based programs; the design, enrollment, site activation, and timing of data from the C-1300-02 trial; the establishment, scope, operation, regulatory basis, and continuation of the Company's named-patient access program in Brazil, including whether per-patient authorizations will be granted and whether the program will generate any receipts; the sufficiency of the Company's cash resources and expected operating runway; and anticipated milestones.
