In a significant milestone for cancer treatment, Merus N.V. has received the U.S. Food and Drug Administration (FDA) approval for BIZENGRI (zenocutuzumab-zbco), marking a breakthrough in the fight against advanced pancreatic adenocarcinoma and nonsmall cell lung cancer (NSCLC) associated with a neuregulin 1 (NRG1) gene fusion.
