Hypercholesterolemia
Conditions
Brief summary
IBI306 is a fully human monoclonal antibody that binds proprotein convertase substilisin/kexin type 9 (PCSK-9), preventing its interaction with the low-density lipoprotein cholesterol receptor (LDL-R) and thereby restoring LDL-R recycling and low-density lipoprotein cholesterol(LDL-C) uptake. This study is being done to investigate the effects of IBI306 in Chinese people with non-familial hypercholesterolemia with very high or high cardiovascular risk. This study will see if IBI306 will reduce low density lipoprotein cholesterol (LDL-C) in Chinese people who are taking a certain type of lipid-lowering medication (statins with or without ezetimibe) and whether it causes any side effects
Detailed description
This is a phase 3, multicenter, double-blind, randomized, placebo-controlled study of IBI306 in Chinese non-familial hypercholesterolemia Subjects with very high or high cardiovascular risk. A total of around 600 subjects who meet admission criteria will be randomized and receive one of the two dose levels of IBI306 or matching placebo: 450mg Q4W, or 600mg Q6W. The double blind period for both groups will be 48 weeks. The study will last 52 weeks
Interventions
Subjects will receive IBI306 450mg every 4 weeks subcutaneously.
Subjects will receive placebo every 4 weeks subcutaneously.
Subjects will receive IBI306 600mg every 6 weeks subcutaneously.
Subjects will receive placebo every 6 weeks subcutaneously.
