A novel – and rapid – anti-cancer drug development strategy has resulted in a new drug that stops kidney and pancreatic tumors from growing in mice. Researchers at the Moores Cancer Center at the University of California, San Diego, have found a drug that binds to a molecular “switch” found in cancer cells and cancer-associated blood vessels to keep it in the “off” position.

“We locked the kinase switch in the off position in cancer and in tumor-associated blood vessels,” which differs from the way current inhibitors attempt to block active kinases, said David Cheresh, PhD, professor and vice chair of pathology at the UCSD School of Medicine and the Moores UCSD Cancer Center, who led the work.
