NEW YORK, March 18, 2022 (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, reported financial results for the fourth quarter and full year 2021.

“We have advanced our allo-iNKT program with multiple clinical programs in solid tumor cancers, multiple myeloma, and a variant agnostic therapy in severe respiratory distress from COVID-19,” said Jennifer Buell, Ph.D., President and CEO of MiNK Therapeutics. “We are leading the field in advancing our proprietary allo-iNKTs alone and in combination with approved checkpoint antibodies in solid tumor cancers. These data build on encouraging signals of benefit in viral ARDS and multiple myeloma with an approach that does not require the hardship of lymphodepletion.”

Launched Allo-iNKTs (AgenT-797) +/- anti-PD-1 in solid tumor cancers

  • Advanced early doses with no lymphodepletion required. Treatment has shown no evidence of cytokine release syndrome or neurotoxicity.
  • Advancing the highest dose cohort (billion cells/dose) and combinations with KEYTRUDA® (pembrolizumab) or OPDIVO® (nivolumab).
  • Data supported by preclinical evidence reported at SITC 2021 showed iNKTs persist (beyond 35 days), traffic to liver, lungs, spleen, and bone marrow, and show anti-cancer activity in solid and liquid cancers.

AgenT-797 in relapsed/refractory multiple myeloma without the need for lymphodepletion shows early signals of clinical activity

  • AgenT-797 shows biomarker suppression and disease stabilization beyond 10 months in relapsed/refractory multiple myeloma with no lymphodepletion.
  • Engineered BCMA-CAR-iNKT and stromal-CAR-iNKT (undisclosed target) have demonstrated potent anti-tumor activity; IND enabling underway with target IND in 2022.

Variant-agnostic nature of AgenT-797 continues to show encouraging survival of >75% in ventilated patients with viral ARDS (COVID-19)

  • Data continue to show substantial improvement over typical survival rates of ~30% in patients with comparable disease. Updated data to be presented in 2H 2022.
  • AgenT-797 has been administered in up to 1 billion cells per dose tolerably, with no lymphodepletion required and with no evidence of cytokine release syndrome or neurotoxicity.

MiNK Therapeutics launches in-house manufacturing of allogeneic native and engineered iNKT cells
