Capturing Immunotherapy Response in a Blood Drop
Johns Hopkins MedicineLiquid biopsies are blood tests that can serially measure circulating tumor DNA (cell-free DNA that is shed into the bloodstream by dying cancer cells). When used in patients with advanced non-small cell lung cancer undergoing immunotherapy, they may identify patients who could benefit from treatment with additional drugs, according to a phase 2 clinical trial in the U.S. and Canada. The trial is led by investigators at the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Institute for Cancer Immunotherapy, BC Cancer and the Canadian Cancer trials Group (CCTG).
