The FDA has given a green light to Foundation Medicine Inc.’s Foundationone CDx as a companion diagnostic for Takeda Pharmaceutical Co. Ltd.’s Alunbrig to identify patients with anaplastic lymphoma kinase (ALK)-positive metastatic non-small-cell lung cancer (NSCLC). The approval comes as Laboratory Corp. of America Holdings (Labcorp) is launching a companion diagnostic to identify NSCLC patients with the KRAS mutation. NSCLC accounts for about 85% of all lung cancers, with an estimated 1.8 million new cases diagnosed each year worldwide. Of those, 3% to 5% carry the ALK gene mutation, which is often missed with standard testing methods.
