|Condition or disease||Intervention/treatment||Phase|
|Acute Myelogenous Leukemia Acute Myeloid Leukemia Acute Myeloid Leukemia With Maturation Acute Myeloid Leukemia Without Maturation ANLL||Biological: anti-CD33 CAR-NK cells||Phase 1 Phase 2|
Determine the safety and feasibility of the chimeric antigen receptor NK92 cells transduced with the anti-CD33 vector (referred to as anti-CD33 CAR-NK cells).
I. For patients with detectable disease, measure anti-leukemia response due to anti-CD33 CAR-NK cell infusions.
II. For patients with stored or accessible leukemia blasts, determine leukemia cell killing by anti-CD33 CAR-NK in vitro.
III. Determine if cellular or humoral host immunity develops against the murine anti-CD33.
OUTLINE: Patients are assigned to 1 group according to order of enrollment.
Patients receive anti-CD33 CAR-NK (coupled with CD28, CD137 and CD3 zeta signalling domains) vector-transduced NK92 cell line on days 0,3, and 5 in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed intensively for 6 months, every 3 months for 2 years, and annually thereafter for 10 years.

Experimental: CAR-NK Cell immunotherapy
Enrolled patients will receive CAR-NK cells immunotherapy with a novel specific chimeric antigen receptor targeting CD33 antigen by infusion.
Biological: anti-CD33 CAR-NK cells
The allogeneic NK cells (NK-92 cell line for clinical use) are engineered to contain anti-CD33 attached to TCRzeta, CD28 and 4-1BB signaling domains. These modified cells are called chimeric antigen receptor NK cells with specificity for CD33.
Other Name: Chimeric antigen receptor NK92 cells with specificity for CD33
- Adverse events attributed to the administration of the anti-CD33 CAR-NK cells [ Time Frame: One year ]Defined as >= Grade 3 signs/symptoms, laboratory toxicities, and clinical events that are possibly, likely, or definitely related to study treatment
- Objective Response Rate [ Time Frame: Up to one year ]Anti-leukemia responses to anti-CD33 CAR-NK cell infusions
