New Colon Cancer Study Suggests Mirati Has The Best KRAS-Blocking Drug
A drug from Mirati Therapeutics designed to block the cancer protein called KRAS shrank tumors in 22% of patients with advanced colon cancer, according to results from a clinical trial presented Sunday. When the Mirati drug, a pill called adagrasib, was combined with another targeted medicine, the colon cancer response increased to 43%. The adagrasib study results are the strongest reported to date for a new class of cancer drugs that work by blocking the effects of a specific type of KRAS alteration called G12C. The Mirati drug is potentially superior to a competing drug from Amgen that won U.S. approval in May to treat patients with KRAS-targeted lung cancer. (Feuerstein, 9/19)
