Ebronucimab (伊喜宁®) is a subcutaneous fully human anti-proprotein convertase subtilisin/kexin type 9 (PCSK9) monoclonal antibody being developed by Akeso Biopharma for the treatment of dyslipidaemia. In September 2024, ebronucimab was approved in China, in combination with statins or statins and other lipid-lowering therapies, for adult patients with primary hypercholesterolaemia [including heterozygous familial hypercholesterolaemia (HeFH)] and mixed hyperlipidaemia who are unable to achieve the low-density lipoprotein cholesterol target after receiving moderate or higher doses of statins.
