Acute lymphoblastic leukemia is the most common childhood cancer, and nine in ten are cured. When it comes back, the odds fall below half.

CAR T cells aimed at a marker called CD19 rescued many of those children. But leukemia learns: some cells drop CD19 and slip away. Cells aimed at a second marker, CD22, get dodged the same way.

The idea: one T cell that watches both doors at once.

A child's own T cells receive one gene that builds both receptors. The National Cancer Institute's earlier two-target design was safe, but the cells faded quickly. This version is rebuilt to last.

Sara Silbert leads it at the NIH Clinical Center, for ages three to thirty-nine. Safety first. Public record; not medical advice.
