MiNK Presents AgenT-797 Clinical Activity in Immune-Compromised Transplant Patient with Severe ARDS at ATS Annual Meeting

Rhea-AI Summary

MiNK Therapeutics has unveiled clinical data on their allogeneic invariant natural killer T (iNKT) cell therapy, agenT-797, in a severe ARDS case at the ATS Annual Meeting. The subject, a 26-year-old post-renal transplant immunocompromised individual who developed severe hypoxemic respiratory failure due to COVID-19, was treated with a single dose of agenT-797. Significant clinical improvements included reduced inflammatory cytokines and successful extubation by day 37. The patient was discharged by day 60 and resumed normal activities within six months. These findings align with Phase 1 trial data, supporting the potential of agenT-797 in treating severe respiratory conditions in immune-compromised patients.

Positive

• Observed rapid decrease in inflammatory cytokines post-treatment.
• Successful extubation of the patient by day 37.
• Patient discharged from the hospital by day 60.
• Patient weaned off hemodialysis and returned to normal activities within six months.
• Data aligns with prior Phase 1 trial results, indicating consistency and reliability.
• Potential of agenT-797 to address critical unmet needs in immune-compromised patients with respiratory distress.

Negative

• Single case study limits the generalizability of results.
• No long-term data provided on the durability of treatment effects.
• High costs and complex logistics associated with cell therapies.
• Potential risks and side effects of allogeneic iNKT cells were not discussed.

NEW YORK, May 22, 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 presentation of clinical data on agenT-797 in a complex case of severe acute respiratory distress (ARDS) at the American Thoracic Society (ATS) Annual Meeting. These translational and mechanistic insights build on an expanding dataset of clinical activity for patients with severe ARDS.

“Consistent with our prior publication of the survival benefit of agenT-797 in severe respiratory distress, the observed improvement in this case further demonstrates the potential of allogeneic iNKT cells in this setting,” said Dr. Terese Hammond, University of California Los Angeles. “New therapeutic options, like allogeneic cell therapies, are urgently needed to address the critical unmet need in immune-compromised individuals with respiratory distress. I believe this growing body of data illuminates how iNKTs may have an impactful role in treating acute critical illness and merits further investigation.”

Clinical Findings

• Patient: A 26-year-old chronically immunosuppressed patient post-renal transplant contracted COVID-19 and progressed to severe hypoxemic respiratory failure, requiring veno-venous extracorporeal membrane oxygenation (VV-ECMO).
• Treatment: A single dose of 1x10^9 allogeneic iNKT cells (agenT-797) on hospital day 13.
• Outcomes: Clinical changes showed a rapid decrease in inflammatory cytokines, including IL-18 following agenT-797 administration, consistent with the data observed in the Phase 1 trial of agenT-797 in COVID-19 ARDS (Hammond, T.C., Nat Commun 2024). The patient was extubated on day 37 and discharged home from the hospital on day 60, weaned off hemodialysis and returned to normal activities of daily living (ADLs) within 6 months of dosing.

FAQ

What is agenT-797 and its significance in treating ARDS?

AgenT-797 is an allogeneic invariant natural killer T (iNKT) cell therapy developed by MiNK Therapeutics. It shows potential in treating severe acute respiratory distress syndrome (ARDS) by reducing inflammatory cytokines and improving clinical outcomes in immune-compromised patients.

What were the key outcomes of the agenT-797 treatment in the severe ARDS case?

The key outcomes included a rapid decrease in inflammatory cytokines, successful extubation by day 37, discharge from the hospital by day 60, and the patient resuming normal activities within six months.

How does agenT-797 align with MiNK Therapeutics' previous clinical data?

The clinical improvements observed in this ARDS case are consistent with data from MiNK Therapeutics' Phase 1 trial of agenT-797 in COVID-19 ARDS, supporting its potential efficacy.

What are the limitations of the agenT-797 clinical data presented?

The data is based on a single case study, limiting its generalizability. Additionally, long-term effects and potential risks or side effects were not discussed.

What are the next steps for the development of agenT-797?

Further investigation and larger clinical trials are needed to confirm the efficacy and safety of agenT-797 in treating severe respiratory conditions in immune-compromised patients.
