What is a checkpoint inhibitor drug?
Immunotherapy drugs called immune checkpoint inhibitors work by blocking checkpoint proteins from binding with their partner proteins. This prevents the “off” signal from being sent, allowing the T cells to kill cancer cells. One such drug acts against a checkpoint protein called CTLA-4.
Can killer T cells cure cancer?
Although CAR T-cell therapies are not as widely used as immune checkpoint inhibitors, they have shown the same ability to eradicate very advanced leukemias and lymphomas and to keep the cancer at bay for many years . Since 2017, six CAR T-cell therapies have been approved by the Food and Drug Administration (FDA).
