Laboratory-Treated T Cells in Treating Patients With High-Risk Relapsed Acute Myeloid Leukemia, Myelodysplastic Syndrome, or Chronic Myelogenous Leukemia Previously Treated With Donor Stem Cell Transplant

Complete title: Phase I/II Study of Adoptive Immunotherapy with Virus Specific CD8+ T Cells that have been Transduced to Express a WT1-Specific T Cell Receptor for Patients with Relapsed AML

Research Study Number 2498.00
Principal Investigator Daniel Egan
Phase I/II

Research Study Description

This phase I/II trial studies the side effects of laboratory-treated T cells and to see how well they work in treating patients with high-risk acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), or chronic myelogenous leukemia (CML) that has returned after a period of improvement (relapsed), previously treated with donor stem cell transplant. Biological therapies, such as cellular adoptive immunotherapy, may stimulate the immune system in different ways and stop cancer cells from growing. Placing a gene that has been created in the laboratory into a person's T cells may make the body build an immune response to kill cancer cells.

Eligibility Criteria (must meet the following to participate in this study)

Ages Eligible for Study: Child, Adult, Senior

Sexes Eligible for Study: All

- Patients must express HLA-A*0201

- Patients who are currently undergoing or who previously underwent matched allogeneic HCT for:

-- * AML: Prospective enrollment will now be limited to patients with relapsed disease (overt relapse or minimal residual disease) at any time post allogeneic HCT

-- * MDS will no longer be a criterion for eligibility

-- * CML will no longer be a criterion for eligibility

- Patients must have an HLA-matched donor of hematopoietic stem cells (related or unrelated)

- Patients must be able to provide blood and bone marrow samples and undergo the procedures required for this protocol

- Patients must be >= 15 kg

- Patients must be able to give informed consent; parent or legal representative will be asked to consent for patients younger than 18 year old


- Patient and donor (related or unrelated) must be HLA-matched and express HLA-A*0201

- Donor must be Epstein?Barr virus (EBV) or cytomegalovirus (CMV) seropositive

- Donor must be age 18 or older

- In good general health

- Able to give informed consent

Other eligibility criteria may apply.

Exclusions (conditions that would prevent participation in this study)

- Central nervous system (CNS) tumor refractory to intrathecal chemotherapy and/or cranio-spinal radiation

- In patients whose leukemic cells are available for evaluation, the expression of WT1 in the patient's bone marrow will be determined; if WT1 expression in the patient?s bone marrow is not highly expressed by polymerase chain reaction (PCR), the patient will be excluded from the study; patients with no evaluable leukemia will be eligible for enrollment based on the high frequency of positive leukemias (> 90%), and leukemia will be evaluated for WT1 expression if recurrence is detected

- Human immunodeficiency virus (HIV) seropositive; testing for HIV should be within 6 months of enrollment

- Medical or psychological conditions that would make the patient unsuitable candidate for cell therapy at the discretion of the principal investigator (PI)

- Pregnancy or breast-feeding; women of childbearing potential must have a negative serum or urine beta-human chorionic gonadotropin (B-hCG) pregnancy test result within 14 days before the first dose of WT1-specific T cell infusion; woman of non-childbearing potential will be defined as being postmenopausal greater than one year or who have had a bilateral tubal ligation or hysterectomy; all recipients of WT1-specific T cells will be counseled to use effective birth control during participation in this study and for 12 months after the last T cell infusion


- Less than 18 years old

- Active infectious hepatitis

- HIV or human T-lymphotropic virus (HTLV) seropositive

- Pregnancy or nursing

- Significant medical conditions (e.g. immunosuppressive therapy) that would make the donor an unsuitable T cell donor

- Unable to give informed consent

Other exclusion criteria may apply.
