SAN DIEGO and AUSTIN, TX and HAMILTON, ON – Feb. 5, 2024 /PRNewswire/ — Triumvira Immunologics, a clinical-stage company developing novel, targeted autologous and allogeneic T cell therapeutics that co-opt the natural biology of T cells to treat patients with solid tumors, today announced that the first patient has been dosed in its TACTIC-3 trial, a Phase I/II study, (NCT05862324) investigating the safety and efficacy of autologous TAC-T cell asset, TAC101-CLDN18.2, targeting Claudin 18.2+ solid tumors. TAC101-CLDN18.2 is a novel cell therapy based on genetically engineered autologous T cells expressing a T-cell Antigen Coupler (TAC) that harnesses the inherent signaling pathways of the native T cell receptor complex and targets Claudin 18.2, an epithelial transmembrane protein overexpressed in gastric cancer and several other solid tumor types.

“Claudin 18.2 is a promising target for cell therapy,” said Andreas Bader, Ph.D., Chief Scientific Officer of Triumvira Immunologics. “Among normal tissues, it is restricted to the stomach and hidden between neighboring cells. In gastric cancer and a few other solid tumors, however, it is accessible and abundantly expressed on tumor cell surfaces and, therefore, it represents a significant tumor selective opportunity to address these types of cancers.”
