Chimeric Antigen Receptor T-Cells for the Treatment of Acute Myeloid Leukemia Expressing CLL-1 Antigen (CARMEN) (H-43516)



Chimeric Antigen Receptor T-Cells For The Treatment Of Acute Myeloid Leukemia Expressing  Cll-1 Antigen – CARMEN

Patients eligible for this study have a type of blood cancer Acute Myeloid Leukemia (AML) which has come back or has not gone away after treatment.

The body has different ways of fighting disease and infection, and this research study combines two different ways of fighting cancer with antibodies and T cells with the hope that they will work together. T cells (also called T lymphocytes) are special infection-fighting blood cells that can kill other cells including tumor cells. Antibodies are types of proteins that protect the body from bacterial and other infectious diseases. Both antibodies and T cells have been used to treat patients with cancers; they have shown promise, but have not been strong enough to cure most patients when used alone.

T lymphocytes can kill tumor cells but there normally are not enough of them to kill all the tumor cells. Some researchers have taken T cells from a person's blood, grown more of them in the laboratory and then given them back to the person. The antibody used in this study targets CLL-1. This antibody sticks to AML cells because of a substance (protein) on the outside of these cells called CLL-1. For this study, the antibody to CLL-1 has been changed so that instead of floating free in the blood, it is now joined to the T cells. When T-cells contain an antibody that is joined to them, they are called chimeric antigen receptor T-cells or CAR-T cells.

In the laboratory, the investigators have also found that T cells work better if proteins that stimulate T cells are also added, such as one called CD28. Adding the CD28 makes the cells grow better and last longer in the body, thus giving the cells a better chance of killing the leukemia or lymphoma cells. In this study we are going to attach the CLL-1 chimeric receptor that has CD28 added to it to the patient's T cells. We will then test how long the cells last.

These CLL-1 chimeric antigen receptor T cells with CD28 are investigational products not approved by the Food and Drug Administration.
