Brief Summary:

This study uses special blood cells called multiple tumor-associated antigen (TAA)-specific T cells to treat patients with acute lymphoblastic leukemia (ALL) which has come back, or may come back, or has not gone away after standard treatment, including an allogeneic hematopoietic stem cell transplant (HSCT).

The investigators have previously used this sort of therapy to treat Hodgkin or non-Hodgkin lymphomas that are infected with Epstein-Barr virus (EBV). EBV is found in cancer cells of up to half of all patients with Hodgkin and non-Hodgkin lymphoma. This suggests that it may play a role in causing lymphoma. The cancer cells infected by EBV are able to hide from the body's immune system and escape being killed. The investigators previously tested whether special white blood cells (called T cells) that were trained to kill EBV-infected cells could affect these tumors, and in many patients the investigators found that giving these trained T cells caused a complete or partial response.

Other cancers express specific proteins that can be targeted in the same way. The investigators have been able to infuse such tumor-targeted cells into up to 10 patients with lymphoma who do not have EBV, and seen some complete responses. Importantly, the treatment appears to be safe. Therefore, the investigators now want to test whether the investigators can direct these special T cells against other types of cancers that carry similar proteins called tumor-associated antigens (TAAs). These proteins are specific to the leukemia cell, so they either do not show up, or show up in low quantities, on normal human cells.

The investigators will grow T cells from patients' stem cell donors in the laboratory in a way that will train them to recognize the tumor proteins WT1, PRAME and Survivin, which are expressed on most ALL cancer cells. The cells will be infused at least 30 days post-allogeneic HSCT. In this study, the investigators want to see whether these cells will be able to recognize and kill leukemia cells that express these antigens. These donor-derived multiTAA-specific T cells are an investigational product not yet approved by the U.S. Food and Drug Administration.

The purpose of this study is to find the largest safe dose of donor-derived multiTAA-specific T cells for patients with ALL.


Condition or disease Intervention/treatment Phase
Leukemia, Lymphoblastic (Acute) Biological: MultiTAA-specific T cells Phase 1

Detailed Description:

To make donor-derived multiTAA-specific T cells, the investigators will collect blood from the patient's stem cell donor, and mix the donor's T cells with small pieces of the tumor proteins WT1, PRAME and Survivin. These protein fragments stimulate the donor T cells to grow and react against these proteins in such a way that they will recognize and kill cancer cells that express these proteins. Once sufficient numbers of multiTAA-specific T cells have been made, the investigators test them to make sure they target the patient's cancer cells, but not their normal healthy cells.

The multiTAA-specific T cells will be administered as a single intravenous (IV) infusion over 10 minutes. The patient's cancer will be assessed within 4 weeks prior to the T cell infusion, at 4-6 weeks, and again at 8-12 weeks after the infusion. If at least 4 weeks after the infusion there is no change or a reduction in the number of cancer cells measured in the bone marrow, or a decline in cancer-specific markers in the blood, patients may receive up to six (6) additional doses of the T cells at least 4 weeks apart. All of the treatments will be given by the Center for Cell and Gene Therapy at Houston Methodist Hospital or Texas Children's Hospital.

For at least 4 weeks after the infusion, patients may not receive any other anti-cancer treatments, such as radiation therapy or chemotherapy, with the exception of drugs like dasatinib. Patients who do receive any other therapies will be taken off treatment, and will not be able to receive additional doses of T cells.

This is a dose escalation study, which means that at the beginning, patients will be started on the lowest dose (1 of 3 different levels) of T cells. Once that dose level proves safe, the next group of patients will be started at the next highest dose. This process will continue until all 3 dose levels have been studied. If side-effects are too severe, the dose will be lowered or the T cell injections will be stopped.

Before being treated, patients will undergo a series of standard medical tests:

  • Physical exam.
  • Blood tests to measure blood cells, kidney and liver function.
  • Measurement of ALL (done by a bone marrow biopsy or blood tests).
  • Pregnancy test, if patient is a female who can have children.

Patients will undergo standard medical tests both during the T cell infusions and after:

  • Blood tests to measure blood cells, kidney and liver function.
  • Measurement of disease 4-6 weeks and 8-12 weeks after the T cell infusion (done by bone marrow biopsy or blood tests).

Active participation in this study will last for approximately one (1) year. If the patient receives additional doses of the T cells as described above, their active participation will last until one (1) year after the last dose of T cells. We will then contact the patient once a year for up to 4 additional years (total of 5 years follow-up) in order to evaluate disease response long-term.

Arm Intervention/treatment
Experimental: Group A
Treatment with donor-derived multiTAA-specific T cells as adjuvant therapy following HSCT for ALL.
Biological: MultiTAA-specific T cells

The 3 dose levels are:

Dose Level 1: 5 x 10e6 cells/m2; Dose Level 2: 1 x 10e7 cells/m2; Dose Level 3: 2 x 10e7 cells/m2

The T cells are given from 30 days post-HSCT. They are administered by intravenous injection over 1-10 minutes through either a peripheral or a central line.

Patients being treated on Arm A (adjuvant) or Arm B (active disease) who have a partial response, complete response or stable disease, will be eligible to receive up to 6 further doses of multiTAA-specific T cells at the same dose as the initial infusions at a minimum of 4 weeks apart.

Dose Level 1: 5 x 10e6 cells/m2; Dose Level 2: 1 x 10e7 cells/m2; Dose Level 3: 2 x 10e7 cells/m2

The T cells are given from 30 days post-HSCT. They are administered by intravenous injection over 1-10 minutes through either a peripheral or a central line.

Donor Eligibility:

Donors for allogeneic (i.e. HLA matched or mismatched related or unrelated) stem cell transplants who have fulfilled eligibility for and consented to stem cell donation as per the stem cell transplant program's standard operating procedures. Subjects must be at least 12 kg or 24 pounds to be eligible for stem cell donation. The stem cell donor will have already been selected by the primary Bone Marrow Transplant attending according to CAGT SOPs for Donor Evaluation, Donor Selection, and Donor Deferral. If a donor has been chosen for the transplant based on urgent medical need, that same donor will also be used for T cell generation, provided that there are no new reasons for ineligibility since the stem cell collection. In this study, the subject's hematopoietic stem cell donor will also be the donor for the T cells.
