This research study uses special blood cells called multiple tumor-associated antigen (TAA)-specific T cells (a new experimental therapy) to treat patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) 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), the virus that causes infectious mononucleosis ("mono" or the "kissing disease"), 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 causes a complete or partial response.

In several lymphomas and other types of cancer like AML or MDS, the cancer cells do not have EBV. The do however express other 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, or 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, NY-ESO-1, PRAME, and Survivin, which are expressed on most AML and MDS cancer cells. The cells will be infused at least 30 days post-allogeneic stem cell transplant. In this study, the investigators want see whether these cells will be able to recognize and kill cancer 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 tumor protein multiTAA-specific T cells for patients with AML or MDS.

Study Date: 
Mon, 02/01/2016 to Mon, 04/01/2019
Bone Marrow Disease(s): 
myelodysplastic syndromes (MDS)
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 central lie. If patients with residual disease (Group B) have a partial response, complete response or stable disease, they will be eligible to receive up to 6 further doses of multiTAA-specific T cells at the same dose as the initial infusions every 4-6 weeks. Other Name: Multiple tumor-associated antigen (TAA)-specific T cells
