IMPT-314, a dual-targeting CD19/CD20 CAR T-cell therapy, showed 94% ORR and 71% CR in CAR T-naïve large B-cell lymphoma patients with manageable safety. No Grade 3+ CRS and low Grade 3 ICANS were reported, with rapid resolution using standard protocols. IMPT-314 demonstrated robust expansion and peak cell expansion between Days 7-28 post infusion, with a final product enriched for naïve and central memory T cells.
