Amgen announced that the Japanese Ministry of Health, Labour and Welfare has approved the cholesterol-lowering medication Repatha® (evolocumab) Injection, the first proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor to be approved in Japan. Repatha is a human monoclonal antibody that inhibits PCSK9, a protein that reduces the liver's ability to remove low-density lipoprotein cholesterol (LDL-C), or "bad" cholesterol, from the blood. Repatha was developed in Japan by Amgen Astellas BioPharma K.K. (AABP), a joint venture between Amgen and Astellas Pharma Inc., a pharmaceutical company headquartered in Tokyo.
