AUSTIN, Texas and HAMILTON, ON and SOUTH SAN FRANCISCO, Calif., Oct. 30, 2023 /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 it will participate with one oral presentation and four posters at the Society for Immunotherapy of Cancer (SITC) 2023 Annual Meeting in San Diego, California, from November 1-5. The company will showcase clinical and preclinical data across various programs, including its ongoing Phase I/II study investigating the safety and efficacy of autologous TAC-T cells targeting human epidermal growth factor receptor 2 (HER2) in relapsed or refractory solid tumors (TACTIC-2 /NCT04727151) and its CLDN18.2, GUCY2C and allogeneic TAC T cell technologies.
TAC01-HER2 is an innovative cell-based therapy that involves the utilization of genetically modified T cells derived from the patient themselves. These cells express a T-cell Antigen Coupler (TAC) which is designed to specifically recognize HER2 in tumors. In addition to the TAC01-HER2 candidate, the company is investigating TAC-GUCY2C for the treatment of colorectal cancer and TAC01-CLDN18.2 for the treatment of pancreatic ductal adenocarcinoma and gastric cancer.
"The new data we are presenting at SITC demonstrates the robustness of our TAC-T cells platform and its potential for precise targeting of malignant cells expressing tumor-associated antigens such as HER2, Claudin 18.2 and GUCY2C," stated Dr. Paul Lammers, CEO of Triumvira Immunologics. "Our commitment to developing innovative T cell therapeutics that harness the natural biology of T cells is supported by the promising preliminary results from our ongoing Phase I/II study targeting HER2 in solid tumors. In addition, we are advancing our pipeline by evaluating the clinical efficacy of TAC01-CLDN18.2, a novel autologous cell therapy that recognizes Claudin 18.2, a promising therapeutic target that is selectively over-expressed in gastric cancers and other solid tumors."

About Triumvira Immunologics
Triumvira Immunologics, Inc. ("Triumvira") is a leading clinical-stage solid tumor cell therapy company developing unique, non-gene edited, first-in-class targeted autologous and allogeneic T cell therapeutics that co-opt the natural biology of T cells to treat patients with solid tumors. The company's proprietary T cell Antigen Coupler (TAC) technology is a robust and versatile platform that activates natural T cell functions differently from cell therapies such as CAR-T and engineered T cell receptor (TCR) therapies. Triumvira is developing a broad pipeline targeting promising tumor-associated antigens such as HER2, Claudin 18.2, GUCY2C and GPC3. Triumvira is headquartered in Austin, Texas, with research facilities in Hamilton, Ontario, and GMP manufacturing facilities in South San Francisco, California.
