About this study

Official title: A Phase 1 Safety Study of Adoptive Cellular Therapy Using Autologous T Cells Transduced With Lentivirus to Express a CD33 Specific Chimeric Antigen Receptor in Patients With Relapsed or Refractory CD33-Positive Acute Myeloid Leukemia

Any time the words "you," "your," "I," or "me" appear, it is meant to apply to the potential participant.

The goal of this clinical research study is to learn about the safety and tolerability of 3 different doses of CD33-CAR-T cells (referred to throughout the consent as "T-cells") in patients who have CD33-positive acute myeloid leukemia (AML) that is relapsed (has come back) or refractory (has not responded to treatment).

CD33-CAR-T is made by genetically modifying (changing) your T-cells (a type of white blood cell). T-cells are genetically changed to help target leukemia cells.

This is an investigational study. CD33-CAR-T is not FDA approved or commercially available. It is currently being used for research purposes only. The study doctor can explain how the study drug is designed to work.

Up to 39 participants will be enrolled in this study. All will take part at MD Anderson.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • LeukapheresisProcedure or surgery

    After enrollment, steady state leukapheresis performed to collect apheresis material. The goal is to achieve a target total nucleated cell (TNC) yield of at least 5 x 10^9 (expected range 5 x 10^8 - 5 x 10^10), for up to two days.

  • FludarabineDrug

    Also called Fludarabine Phosphate, Fludara

    25 mg/m2 administered by vein on Days -5 to -3.

  • CyclophosphamideDrug

    Also called Cytoxan, Neosar

    900 mg/m2 administered by vein on Day -3.

  • CD33-CAR-T Cell InfusionBiological

    CD33-CAR-T cell infusion administered by vein on Day 0. First group of participants receive the lowest dose level. Each new group will receive a higher dose than the one before it, if no intolerable side effects were seen. This will continue until the highest tolerable dose of T-cells is found. Starting dose level is > 1.5 x 105/kg but ≤ 4.5 x 105/kg.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Recommended Phase II Dose (RP2D) of CD33-CAR-T Cells

    RP2D defined as the highest dose level in which 6 patients have been treated with at most 1 instance of dose limiting toxicity (DLT).

    DLT is defined as a clinically significant adverse event or abnormal laboratory value assessed as unrelated to disease progression, intercurrent illness, or concomitant medications and occurring during the first course on study that meets any of the following criteria:

    • CTCAE grades non-reversible grade 3, or any grade 4-5 allergic reactions related to the study cell infusion.
    • CTCAE grades non-reversible grade 3, or any grade 4-5 autoimmune reactions related to the study cell infusion.
    • CTCAE grades non-reversible grade 3, or any grade 4-5 organ toxicity (cardiac, dermatologic, gastrointestinal, hepatic, pulmonary, renal/genitourinary, or neurologic) not pre-existing or due to the underlying malignancy and occurring within 28 days of study product infusion related to study cell infusion.

    Measured: 28 days after completion of the CD33-CAR-T infusion

Secondary outcomes (1)
  1. Disease Response to CD33-CAR-T Cells

    Response to treatment evaluated according to the World Health Organization (WHO) standardized response criteria for myelodysplastic syndromes.

    Disease response to CD33-CAR-T cells defined as Complete Remission (CR), Complete Remission without Platelet Recovery (CRp), Complete Remission without Neutrophil Recovery (CRn), Complete Remission with Incomplete Blood Count Recovery (CRi), Partial Remission (PR) or Non-responder (NR).

    Measured: On Day 7, at Weeks 2, 4, and 8, and at Months 3, 6, and 12 after CD33-CAR-T Cell infusion

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Leukapheresis, Fludarabine and Cyclophosphamide in people with Hematopoietic/Lymphoid Cancer and Acute Myeloid Leukemia, run by M.D. Anderson Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 13 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 4 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Terminated per the PI's request.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Recommended Phase II Dose (RP2D) of CD33-CAR-T Cells (time frame: 28 days after completion of the CD33-CAR-T infusion). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Nov 2019.
