    Phase 1/2 Study of Donor-Derived Anti-CD33 Chimeric Antigen Receptor Expressing T Cells (VCAR33) in Patients with Relapsed or Refractory Acute Myeloid Leukemia after Allogeneic Hematopoietic Cell Transplantation (ASH 2023)
    CD33 is a preferential target for AML CAR T cell therapy as it is expressed on the majority (>80%) of AML blasts and because prior clinical experience with gemtuzumab ozogamicin (GO; tradename: MylotargTM) has demonstrated the safety and efficacy of targeting CD33...Patients will receive lymphodepletion on days -5 to -2 with fludarabine (total 120 mg/m2) and cyclophosphamide (total 1000 mg/m2) followed by infusion of VCAR33 on Day 0...*NCT number pending. Clinical trial information submitted to CT.gov on July 19, 2023.
