We report extended follow-up (median: 77.77 months) of 122 patients with r/r B-NHL who received either dual-targeted CD19/CD22 CAR-T-cell therapy alone (cohort A, n = 65) or following sequential autologous stem cell transplantation (ASCT; cohort B, n = 57). The gene discussed is CD22; the disease is non-Hodgkin lymphoma.
