NCT ID: NCT03815812

Last Updated: 2023-11-18

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 60 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2019-03-07
• Study Completion Date: 2019-12-25

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.
