Scientists test 'Tag-and-Kill' cancer therapy for tough bone tumors

This early-stage study is testing a new two-part treatment for osteosarcoma that has come back or not responded to standard therapies. Doctors take a patient's own immune cells (T cells), modify them in a lab to recognize a special marker, and then infuse them back. A second drug is given to 'tag' the tumor cells with that marker, guiding the modified immune cells to find and attack the cancer. The main goal is to see if this combination is safe and feasible to make for up to 21 patients.
