Ribociclib (Kisqali, Novartis Pharmaceuticals Corp.) and abemaciclib (Verzenio, Eli Lilly and Company) are widely-watched new drugs for treating breast cancer. The two drugs are cyclin-dependent kinase 4/6 (CDK4/6) inhibitors. Niraparib (Zejula, Tesaro, Inc.), a poly ADP-ribose polymerase (PARP) inhibitor, for the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in complete or partial response to platinum-based chemotherapy. Brigatinib (Alunbrig tablets, Takeda Pharmaceutical Company Limited, through its wholly owned subsidiary ARIAD Pharmaceuticals, Inc.) for the treatment of patients with metastatic anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC). Midostaurin (Rydapt, Novartis Pharmaceuticals Corp.) was approved for the treatment of adult patients with newly diagnosed acute myeloid leukemia (AML) who are FLT3 mutation-positive (FLT3+). This is a major breakthrough in the recent 25 years.
