Study Title

Phase 1/2a, Single Dose Study Investigating NTLA-5001 in Subjects with Acute Myeloid Leukemia


This study will be conducted to evaluate the safety, tolerability, cellular kinetics (CK), activity, and pharmacodynamics (PD) of NTLA-5001 in participants with Acute Myeloid Leukemia (AML).


Primary: Dose Escalation: To identify dose for use in the expansion cohorts Dose Expansion: To evaluate the safety and tolerability of NTLA-5001 in subjects with AML and lower disease burden (Arm 1) and in subjects with AML and higher disease burden (Arm 2) Secondary: -To characterize the cell kinetics (CK) of NTLA-5001 in peripheral blood -To estimate the anti-tumor activity of NTLA-5001 in subjects with AML Exploratory: -To estimate other cancer-related outcomes in subjects with AML -To characterize subject AAV exposure -To characterize immunologic parameters and characteristics of NTLA-5001 cells after administration in subjects with AML



Chemotherapy (NOS); Therapy (NOS)


NTLA-5001 (); cyclophosphamide (); cytoxan (cyclophosphamide); fludarabine (Fludarabine phosphate)
