Early trial tweaks immune system to fight blood cancer

This small, early-stage study tested whether temporarily removing a specific type of immune cell, called a regulatory T cell, during a patient's own stem cell transplant could be done safely for people with multiple myeloma. The goal was to see if this change might help the immune system better fight the cancer after the transplant. Researchers enrolled 30 patients to compare different methods of removing these cells and monitor for side effects and treatment response.
