Without wanting to get into parsing the word 'cure' imho this is a cancer cure. The reason the treatment kills the B-cells as well is because that is how it identifies the cancer cells. It is the marker that enables the T cells to recognize the cancer cells. But the fact that it kills the B cells does not mean that it does not successfully treat the cancer cells. It appears that it does. And hence it seems fair to call it a cure.
