The poster, titled &#39;Novel Invariant Natural Killer T Cell (agenT-797) and Interleukin-15 Superagonist (N-803) Combination Immunotherapy for Unresolving Coccidioides immitis Infection with Concurrent ARDS,&#39; was presented by Terese C. Hammond, M.D., Head of Inflammatory and Pulmonary Diseases at MiNK Therapeutics, and describes a sequential immunotherapy regimen pairing agenT-797, MiNK&#39;s investigational off-the-shelf iNKT cell therapy, with Anktiva&#xAE; (N-803), an FDA-approved IL-15 superagonist developed by ImmunityBio, reflecting a combination strategy built on two clinically validated immune mechanisms. The patient was critically ill, facing a convergence of severe threats: disseminated Coccidioides immitis (valley fever) fungal infection, severe acute respiratory distress syndrome (ARDS), and concurrent hospital-acquired Pseudomonas aeruginosa bacterial pneumonia, all after standard-of-care antifungal, antibacterial, and supportive therapies had failed to halt clinical decline. Key Clinical and Translational Findings Following sequential treatment with Anktiva (N-803) and agenT-797, investigators observed: <ul type="disc"><li style="margin-top:5pt; margin-bottom:5pt;">Suppression of both fungal and bacterial pathogens</li><li style="margin-top:5pt; margin-bottom:5pt;">Active immune cell recruitment into the lung</li><li style="margin-top:5pt; margin-bottom:5pt;">Reduced early inflammatory signaling</li><li style="margin-top:5pt; margin-bottom:5pt;">Activation of tissue repair and immune regulatory pathways </li></ul> Immune profiling revealed a coherent biological sequence: Anktiva triggered early immune activation, followed by agenT-797-driven changes consistent with iNKT cell engagement, pathogen control, and a transition from inflammation toward resolution and repair. The pattern suggests the treatment sequence may have helped restore coordinated immune function in a patient whose infection and respiratory failure had continued to progress despite intensive intervention. "These observations are clinically and biologically important because they point to a pattern we are increasingly seeing across severe lung injury where immune failure itself may become a dominant driver of poor outcomes," said Terese Hammond, M.D., Head of Inflammatory and Pulmonary Diseases at MiNK Therapeutics. "As a practicing pulmonary critical care physician, what stands out in this case is not only the reduction in inflammatory signaling, but the evidence of immune recovery and pathogen control in a patient whose infection had persisted despite intensive antifungal, antibacterial and supportive therapy. Many critically ill patients do not decline from early inflammation alone. They deteriorate later from prolonged respiratory failure, secondary infections, immune exhaustion and multi-organ dysfunction. While this is a single case and must be interpreted with appropriate caution, the findings support the clinical question we are now studying prospectively, whether restoring immune competence can change the trajectory for patients with severe pneumonia, respiratory failure and critical illness." The patient&#39;s family ultimately pivoted to comfort care due to recurrent cardiac decompensation in the setting of pre-existing mitral valve disease, acute mitral regurgitation and cardiogenic shock. The authors further supported this rationale in the ATS poster presentation, when chest imaging, clinical data including real time pulmonary arterial catheter and cardiac echocardiography data augmented post-mortem cytokine and biomarker results to prioritize acute heart failure rather than cytokine release or infectious contributions as the most likely mechanism. The ATS presentation and Clinical Immunology Communications publication build on MiNK's prior clinical experience with agenT-797 in moderate to severe ARDS, where the therapy was associated with a favorable safety profile, improved survival rate and decreased secondary infection rates. The new findings also support MiNK's broader platform thesis that iNKT cells may respond dynamically to the immune environment they encounter, with potential relevance across oncology, severe lung injury, persistent infection and immune dysfunction. Expanding on these findings, MiNK recently <a href="https://www.globenewswire.com/Tracker?data=zlGo9Dib6jWuIVMZMaintfAA44nF580UpYgkCnrV9CwSSkEIQ19hZ03IndTW80f2lIfD51G_msuMOiwn7yYuRqoN40QUhb28e2I3HmQn3Ib5U1kZNUMskdIKgpApsewLiaWdmORfFS_9uyJL2W9bv8EIGm2zLtXNni_N0mN8RzyfvQd0-6W2tpPOCLbhRxZ31ZqaS6WdfliZRX8jrnbBuR1nhMhvvfJMwn61qKABrbO1z1JOuf22uYq2WjFNFzeP" rel="nofollow" target="_blank">announced the initiation</a> of a randomized Phase 2 clinical trial evaluating agenT-797 plus standard of care compared with placebo plus standard of care in adults with severe acute lung injury and critical illness, including moderate to severe acute hypoxemic respiratory failure due to severe pneumonia, who meet Global ARDS criteria and are admitted to the ICU. The study is designed to prospectively evaluate agenT-797 in a defined critical care population where respiratory recovery, ventilator-free days, secondary infection and survival can be assessed using clinically meaningful endpoints.
