MiNK's Novel FAP-CAR-iNKT Presented at ASGCT

MiNK Therapeutics (Nasdaq: INKT), a clinical-stage biopharmaceutical company specializing in 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 presented preclinical data demonstrating the potential of its novel FAP-CAR-iNKT candidate, MiNK-215, at the American Society of Gene and Cell Therapy (ASGCT) annual meeting.

"MiNK-215 is a powerful and innovative cell therapy that addresses resistance in solid tumor cancers," stated Dr. Marc Van Dijk, CSO of MiNK. "Our growing data strengthens our understanding of MiNK-215's effectiveness in combating the suppressive tumor microenvironment and enhancing other immune cells. We believe this novel therapeutic candidate may address challenging solid tumor cancers. We are advancing this program through development and manufacturing, with an IND filing expected next year."

MiNK-215, an allogeneic FAP-CAR-IL-15 iNKT cell product, is designed to target fibroblast activation protein (FAP) expressing cancer-associated fibroblasts (CAFs) and/or tumor cells. Preclinical findings revealed potent anti-tumor activity, including:

• Robust efficacy in non-small cell lung cancer (NSCLC) models, resulting in substantial tumor elimination in the lungs and improved survival compared to T cells alone.
• Increased killing capacity of partially exhausted T cells, consistent with native iNKT cells' mechanisms (SITC2022).
• Targeting and elimination of FAP-expressing CAFs, disrupting the tumor-promoting stromal network and reducing immunosuppression in the tumor microenvironment.
• Enhanced immune cell infiltration and T cell activation, promoting a potent anti-tumor immune response.
• Augmented persistence and transactivation of effector immune cells through IL-15 secretion.
