Summary

The team has developed the synthetic T cell receptor (TCR) and antigen receptor (STAR) T cells which were demonstrated safety in relapsed or refractory (r/r) B-cell non-Hodgkin' s lymphoma (B-NHL) (NCT05631912). Based on this research, allogeneic STAR-T cell products utilized the CRISPR-Cas9 gene editing tool to knock out endogenous receptor α constant (TRAC), human leukocyte antigen (HLA)-A/B, CIITA, and programmed death 1 (PD-1) genes simultaneously in T cells from healthy donors, and integrated the STAR molecule into the TRAC locus using adenovirus associated virus. This strategy can reduce graft-versus-host-disease (GvHD) toxicity and host-versus-graft response, decrease the sensitivity of STAR T cells to immunosuppressive signals, and improve their anti-tumor activity. In this single center, prospective, open-label, single-arm, phase 1/2 study, the safety and efficacy of allogeneic CD19-targeting STAR T cell therapy will be evaluated in patients with r/r B-NHL.
