Acute myeloid leukemia (AML) is a fast-growing cancer of the blood and bone marrow. The only cure for AML is hematopoietic cell transplant (HCT) using donor stem cells (alloHCT). But up to 60% of patients relapse after treatment. Many AML cells have a surface protein called CD33. Researchers want to try treating people with AML using a study product (VCAR33) that targets and kills cells that have CD33.
Objective:
To test VCAR33 in people with advanced AML.
Eligibility:
People aged 18 years and older with AML that returned after alloHCT. Their original alloHCT donor must be available.
Design:
Participants with AML will be screened. They will have a physical exam with blood and urine tests. They will have chest X-rays and tests of their heart function. They may have a bone marrow biopsy: A sample of soft tissue will be removed from inside a bone.
Donors will undergo apheresis: Blood will be taken from the body through a tube attached to a needle. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be returned to the body. The white blood cells will undergo gene therapy to create VCAR33.
Participants with AML will stay in the hospital for at least 12 days. For the first 5 days, they will take drugs to prepare them for treatment. Then they will receive VCAR33 by infusion into a vein.
After discharge, participants will take their temperature every 6 to 8 hours until day 28.
Follow-up visits will continue for 2 years.

INCLUSION CRITERIA: Each patient must meet the following criteria to be enrolled in this study: 1. Patients aged >= 18 years 2. Patients must have CD33+ R/R or MRD+ AML/MDS after alloHCT 2a. Patients with a history of AML or MDS require >= 0.1% BM malignant blasts by flow cytometry or any circulating malignant blasts 2b. Patients who have undergone alloHCT with VOR33 on the VBP101 protocol (NCT04849910) may be enrolled in the absence of current relapse if primary neutrophil engraftment has been achieved, to be treated with VCAR33 upon morphologic or MRD+ relapse 3. Patients must be a recipient of an 8/8 (A, B, C, DRB1) HLA-matched related or unrelated donor alloHCT. Patients previously transplanted with VOR33 in the VBP101 study who have R/R or MRD+ AML/MDS may also be considered. 4. Disease status at the time of enrollment: 4a. Arm A/Morphologic disease: Defined as >= 5% blasts (bone marrow) post-HCT, or any circulating peripheral blasts 4b. Arm B/MRD positive: < 5% blasts (bone marrow) with minimal residual disease of at least 0.1% CD33+ malignant blast cells by flow cytometry, or prior VOR33 HCT without evidence of relapse. 5. Performance status: Eastern Cooperative Oncology Group (ECOG) 0 or 1 6. Patient must have adequate organ function as defined by: 6a. Cardiac: Left ventricular ejection fraction (LVEF) >= 45% or fractional shortening >= 28% 6b. Pulmonary: Baseline oxygen saturation > 92% on room air at rest 6c. Hepatic: Total bilirubin < 3x institutional upper limit of normal (ULN) (except in case of patients with documented Gilbert s disease < 5x ULN) and aspartate aminotransferase (AST/SGOT)/alanine aminotransferase (ALT/SGPT) < 5x institutional ULN 6d. Renal: Serum creatinine must be <= 1.2x institutional ULN or creatinine clearance (Bullet) 60 mL/min for patients with creatinine levels above institutional normal 7. Original alloHCT donor is available and willing to undergo apheresis 8. Patient must have an option to proceed to a second alloHCT in case stem cell rescue is needed for prolonged aplasia, with a cryopreserved back-up graft available OR an allogeneic HCT donor identified. The allogeneic HCT donor for this second transplant may be the same or different donor as for the first transplant, at the Investigator s discretion. 9. Patient must be willing and able, in the Investigator s opinion, to comply with the study procedures outlined in the study protocol. EXCLUSION CRITERIA: Patients who meet any of the following criteria will be excluded from the study. 1. Patients who have undergone more than one alloHCT 2. Patients who have undergone alloHCT with a mismatched unrelated donor, haploidentical donor, or with umbilical cord blood as the stem cell source 3. Patients who will be less than 100 days post-alloHCT at the time of VCAR33 infusion unless approved by the Sponsor Medical Monitor 4. Patients with any history of Grade III or IV acute GVHD or severe chronic GVHD unless approved by the Sponsor Medical Monitor 5. Patients with evidence of ongoing active acute or chronic GVHD and are taking systemic immunosuppressive agents (> 10 mg daily of prednisone equivalent or other GVHD-directed treatment, including extracorporeal photopheresis). Patients with Grade 1 acute GVHD limited to the skin or mild chronic GVHD limited to the eyes, mouth, or skin controlled with only topical therapy are eligible. 6. Patients with active CNS disease. A lumbar puncture is not required to exclude CNS disease in the absence of clinical signs or symptoms suggesting CNS disease. 7. Patients with hyperleukocytosis (for example, >= 30,000 blasts/microL) or rapidly progressive disease. Hydroxyurea is permitted prior to the start of LD to control blast counts. 8. Patients with the following prior therapy: - DLI within 28 days prior to enrollment - Prior treatment with any CAR T cell therapy product 9. Patients with active or uncontrolled viral, bacterial, or fungal infection 10. Patients with a history of a human immunodeficiency virus (HIV) infection or acute or chronic active hepatitis B or C infection 11. Patients with a history of malignancy other than nonmelanoma skin cancer or carcinoma in situ (e.g., cervix, bladder, or breast) unless disease free for at least 2 years after the last definitive therapy, or unless the malignancy was localized and fully resected 12. Female patients of childbearing potential who are pregnant or breastfeeding 13. Patients with a history of severe hypersensitivity reaction to aminoglycosides Pre-Treatment Criteria Prior to the Start of LD Patients who meet any of the following criteria prior to the start of LD should be withdrawn from the study and should not receive LD. 1.
