Immunicy-1: Targeting BCMA with Cyad-211 to Establish Proof of Concept of an shRNA-Based Allogeneic CAR T Cell Therapy Platform

Off-the-shelf allogeneic CAR T cells derived from healthy donor cells have the potential to overcome many of the issues associated with the time-consuming manufacturing of autologous CAR T cells. However, adoptive transfer of allogeneic T cells carries the risk of graft-versus-host disease (GvHD). Most of the clinical experience with allogeneic CAR T cells is based on gene editing to eliminate T cell receptor (TCR) to mitigate the risk of GvHD. While clearly effective, the downsides of gene editing include multiple manufacturing steps requiring multiple clinical grade reagents, thus extending culture times, which can be associated with T cell exhaustion.
