"Much like a scorpion uses toxin components of its venom to target and kill its prey, we're using chlorotoxin to direct the T cells to target the tumor cells with the added advantage that the CLTX-CAR T cells are mobile and actively surveilling the brain looking for appropriate targets," Barish said. Michael Barish, Ph.D., City of Hope professor and chair of the Department of Developmental and Stem Cell Biology, initiated the development of a CAR using chlorotoxin to target GBM cells. Olson, who is a founder of Blaze Bioscience, serves on the board of directors and is the firm's scientific director, said Franklin and others should be commended for getting a new product to this point so quickly., "They moved from a licensed molecule to human clinical trials in record time and at a record low cost," he said.
