Inclusion Criteria:

* Must have histologically confirmed acute myeloid leukemia (AML) meeting one of the following disease criteria:

  * Second or greater relapse. OR
  * Disease refractory to second or subsequent line of therapy (defined as resistant disease after at least one cycle of each treatment regimen).
* Must have myeloid leukemic blasts that are CD123-positive by flow cytometry as determined by the treating institution.
* Has \>= 5% myeloid leukemic blasts in bone marrow at time of relapse or refractory disease and prior to Screening for this study.
* Performance status by Lansky (\< 16 years old at evaluation) or Karnofsky (\>= 16 years old at evaluation) score \>= 50 or ECOG score \<= 2.
* May have status of central nervous system (CNS)1, CNS2, or CNS3 disease without clinical signs or neurologic symptoms suggestive of CNS leukemia, such as facial nerve palsy, brain/eye involvement or hypothalamic syndrome. Participants receiving intrathecal therapy and no additional CNS-directed systemic therapy at study entry are eligible and may continue treatment as clinically indicated in accordance with institutional practice.

* Prior history of any severity veno-occlusive disease/sinusoidal obstructive syndrome (VOD/SOS) of the liver.
* Prior history of hematopoietic stem cell transplant within 6 months prior to Screening without evidence of active GvHD at the time of screening and the participant is off medications to treat or prevent either post-transplant graft-versus-host disease (GvHD) or post-transplant rejection (except for a stable dose of corticosteroids).
* Have received prior Chimeric Antigen Receptor T-cell (CAR-T) therapy.
