FDA granted accelerated approval to Etcamah (camizestrant) in combination with a CDK4/6 inhibitor (abemaciclib, palbociclib, or ribociclib) for the treatment of adult patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative, locally advanced or metastatic breast cancer upon detection of estrogen receptor-1 mutation during aromatase inhibitor and CDK 4/6 inhibitor therapy, based on an FDA-authorized test.

FDA granted accelerated approval to sevabertinib (Hyrnuo), a kinase inhibitor, for adult patients with locally advanced or metastatic non-squamous non-small cell lung cancer whose tumors have HER2 (ERBB2) tyrosine kinase domain activating mutations, as detected by an FDA-authorized test.
