Brief summary
This is a multi-center, open-label, single-arm, phase I/II trial to evaluate the safety and efficacy of HY004 treatment in Adult patients with relapsed or refractory B-cell Non-Hodgkin's Lymphoma (r/r B-NHL).
Detailed description
This trial is a multi-center, open label, single-arm, phase I/II trial to evaluate the safety and efficacy of HY004 in Adult(aged 18\ 75 years old) patients with r/r B-NHL. The phase I part of the trial is to evaluate the safety, optimal dose of HY004, Pharmacokinetics/Pharmacodynamics(PK/PD)and preliminary efficacy in the treatment of Adult patients with r/r B-NHL. The phase II part of the trial is to evaluate the efficacy and safety of HY004 in in the treatment of Adult patients with r/r B-NHL. The study includes screening, pre-treatment (Cell Product manufacture & lymphodepletion), HY004 infusion , safety and efficacy follow-up, and survival follow-up. All subjects who have received HY004 infusion will be followed for up to 2 years.
Interventions
Autologous 2nd generation bispecific CAR-T cells targeting both CD22 and CD19, single infusion intravenously. Start Dose level: 2.00 x 10\^6/kg CAR+T-cells
