    • Subject's current statin treatment are stable less than 4 weeks prior to random enrollment
    • New York Heart Association (NYHA) III or IV heart failure, or last left ventricular ejection fraction <30%

    • Female subject of childbearing potential not willing to use an acceptable method(s) of effective birth control during treatment with investigational product and for an additional 15 weeks after the end of treatment with investigational product. Male subjects are reluctant to inform their female sexual partners about their participation in the clinical study.
    • Female subject is pregnant or breast feeding, planning to become pregnant or planning to breastfeed during treatment with investigational product and/or within 15 weeks after the end of treatment with investigational product..
    • Subjects have been treated with PCSK9 inhibitors or have participated in other PCSK-9 inhibitor studies

    • Any conditions which, in the opinion of the Investigator, would make the subject unsuitable for enrollment (for example, alcohol or other substance abuse, unable or unwilling to comply with the agreement or mental illness).
    • Currently receiving treatment in another investigational device or drug study, or less than 30 days before randomization since ending treatment on another investigational device or drug study(s) while participating in this study

5. Study Description

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. In phase I study IBI306 was shown to be safe and well tolerated. There was robust reduction in LDL-C, Apo(B), non-HDL-C and lipoprotein (a) in healthy subjects. This study is a randomized, double-blind, placebo-controlled, repeated-dosing, multiple ascending dose trial to evaluate the safety and tolerability of a novel PCSK-9 anti-body, IBI306, in Chinese patients with hypercholesterolemia.
Detailed Description
A total of 60 patients who meet the criteria for admission and have a clinical diagnosis of hypercholesterolemia and have received statin for at least 4 weeks will be randomized and receive different dose groups of IBI306 or matching placebo. Ascending dose design includes 6 dose levels: 75 mg Q2W, 140 mgQ2W, 300 mg Q4W,420mg Q4W, 450 mg Q6W,and 600 mg Q6W. Total duration of the study per subject is 12 weeks.
