Patient-derived TAC01-HER2 TAC T cells produced in Cocoon® Platform is highly functional in models of solid tumors

Background The T cell antigen coupler (TAC) is a novel, proprietary chimeric receptor that facilitates the redirection of T cells to tumor cells, and activates T cells by co-opting the endogenous T cell receptor complex with the goal to elicit safe and durable anti-tumor responses. TAC01-HER2, a 􀈈rst-in-class, autologous TAC T cell product targeting HER2 (ERBB2), has entered a phase I/II clinical trial in patients with HER2-positive solid tumors. Here, we describe the development of an allogeneic HER2-TAC T cell product based on Vγ9Vδ2 (γδ) T cells which belong to a subset of T cells that recognize target cells in a human leukocyte antigen (HLA) independent manner. Thus, γδ T cells do not cause GvHD and have the potential for allogeneic cell therapy applications. View/Download Poster
