A ready-made version of a cutting-edge cancer immunotherapy can effectively defeat blood cancers, a new study says.

Researchers have prepared an off-the-shelf version of CAR immune cell treatment that can be administered more easily to patients with blood cancers.

The new treatment, which uses a type of immune cell called natural killer cells, promoted complete remission in several patients with acute myeloid leukemia (AML), researchers said in a presentation at an American Association for Cancer Research’s (AACR) meeting in Chicago.
