With our cash position, coupled with two separate non-dilutive grants for the clinical advancement of allo-INKTs in GvHD — we can achieve substantial clinical program advancements.”

The patient remains disease-free more than two years post-treatment.
Strengthened Balance Sheet: Increased cash reserves extending runway beyond mid-2026 to advance clinical programs.

Peer-Reviewed Review of iNKT Cell Therapy: A Frontiers in Immunology featured MiNK’s platform, highlighting iNKT cells’ can remodel the tumor microenvironment and overcome therapeutic resistance, showcasing CAR-iNKTs, such as MiNK-215 as a next-generation solution for solid tumors.
