ET 019003

CD19-specific γ/δ TCR-T cells, ET019003, had a good safety profile and could induce rapid responses and durable CR in patients with relapsed or refractory DLBCL, even primary CNS lymphoma, presenting a novel and potent therapeutic option for these patients.

This study provides initial clinical validation of the AbTCR platform as a novel cancer treatment with the potential to provide durable clinical benefit with low toxicity.

We previously developed a human anti-CD19 antibody (ET190L1), and found that ET190L1-TCR-T cells maintained comparable anti-tumor potency with less cytokine release to CD28-costimulated ET190L1-CAR and CD137-based CTL019 T cells (Cell Discov...Cyclophosphamide 250 mg/m 2 on day -5 and fludarabine 25 mg/m 2 on day -5 to -3 were used as the conditioning regimen... These data suggest ET019003-T cells had a good safety profile and could induce durable remission in patients with RR DLBCL, even with primary CNS lymphoma. γ/δ TCR-T cells may present a potential therapeutic option for these patients.
