Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
PURPOSE: This clinical trial is to study genetically engineered lymphocyte therapy in treating patients with CD33 positive acute myeloid leukemias that is relapsed (after stem cell transplantation or intensive chemotherapy) or refractory to further chemotherapy.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
I. Determine the safety and feasibility of the chimeric antigen receptor T cells transduced with the anti-CD33 vector (referred to as CART-33 cells).
II. Determine duration of in vivo survival of CART-33 cells. RT-PCR (reverse transcription polymerase chain reaction) analysis of whole blood will be used to detect and quantify survival of CART-33 TCR zeta:CD137 and TCR (T-cell receptor) zeta cells over time.
SECONDARY OBJECTIVES:
I. For patients with detectable disease, measure anti-leukemia response due to CART-33 cell infusions.
II. To determine if the CD137 transgene is superior to the TCR zeta only transgene as measured by the relative engraftment levels of CART-33 TCR zeta:CD137 and TCR zeta cells over time.
III. Estimate relative trafficking of CART-33 cells in bone marrow.
IV. For patients with stored or accessible leukemia blasts, determine leukemia cell killing by CART-33 cells in vitro.
V. Determine if cellular or humoral host immunity develops against the murine anti-CD33, and assess correlation with loss of detectable CART-33 (loss of engraftment).
VI. Determine the relative subsets of CART-33 T cells (Tcm, Tem, and Treg).
OUTLINE: Patients are assigned to 1 group according to order of enrollment.
Patients receive anti-CD33-CAR (coupled with CD137 and CD3 zeta signalling domains)vector-transduced autologous T cells on days 0,1, and 2 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 13 years.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* CD33+ acute myeloid leukemia CR can not be achieved after at least 2 prior combination chemotherapy regimens.
AML in CR(complete remission)2 or CR3 and not eligible for allogeneic SCT because of age, comorbid disease, or lack of available family member or unrelated donor.
Less than 1 year between last chemotherapy and progression (i.e. most recent progression free interval \< 1 year).
Relapsed after prior autologous or allogenic SCT. AML patients with relapsed or residual disease after at least 1 prior therapy and not eligible for allogeneic SCT.
Residual disease after primary therapy and not eligible for autologous SCT
* Expected survival \> 12 weeks
* Creatinine \< 2.5 mg/dl
* ALT(alanine aminotransferase)/AST (aspartate aminotransferase)\< 3x normal
* Bilirubin \< 2.0 mg/dl
* Any relapse after prior SCT will make patient eligible regardless of other prior therapy
