Scientists at Stanford University have identified a molecule that can be targeted to cure leukemia, the most common form of cancer in childhood.
The therapy is similar to but distinct from CD19-targeted chimeric antigen receptor T-cell therapy, or CAR T-cell therapy, in which a patient’s T cells are genetically modified to target a molecule called CD19 on the surface of the cancer cells.
This therapy was recently approved by the US Food and Drug Administration (FDA) for the treatment of some types of blood cancers, according to a study published in the journal, Nature Medicine.
The therapy genetically modifies a patient’s T cells to target a different molecule called CD22, scientists at Stanford said.
The approach is helpful because the cancer cells of some patients who undergo CD19-targeted CAR T-cell therapy stop expressing the CD19 molecule on their cell surfaces.
CAR T-cell therapy relies on a patient’s own T cells, a type of immune cell that can be a powerful killing machine.
