Phase 1, Open Label, Dose Escalation Study to Evaluate the Safety, Expansion, Persistence, and Preliminary Clinical Activity of Autologous CD64 CAR T Cells in Patients With Relapsed and/or Refractory Acute Myeloid Leukemia (AML) or High-Risk Myelodysplastic Syndromes (HR-MDS)

Study Summary

This is a Phase 1, open label, dose-escalation study to evaluate the safety, expansion, persistence, and preliminary clinical activity of lentivirally transduced autologous T cells expressing anti-CD64 chimeric antigen receptors (CAR) expressing tandem CD3ζ and 4-1BB (CD3ζ/4-1BB) costimulatory domains in subjects with refractory or relapsed (R/R) acute myeloid leukemia (AML) or high-risk myelodysplastic syndromes (MDS). This CAR T cell product will be referred to as "CD64 CAR T" which is CD64 directed, autologous, genetically modified CAR T cells. The primary objective identify the safety profile and maximum tolerated dose (MTD) of CD64 CAR T in subjects with R/R AML or MDS as determined by the defined DLTs using a standard Bayesian Optimal Interval (BOIN) design.
