Heterozygous Familial Hypercholesterolemia

Brief summary

JS002 is a recombinant human anti-PCSK9 monoclonal antibody.The study is a multicenter, randomized, double-blind, placebo-controlled Phase III clinical study in Chinese patients with heterozygous familial hypercholesterolemia (HeFH). Objective To evaluate the efficacy and safety of JS002 150 mg (Q2W) and 450 mg (Q4W) subcutaneous injection (SC).

Detailed description

A randomized, double-blind, placebo-controlled Phase III clinical study evaluating the efficacy and safety of JS002 in patients with heterozygous familial hypercholesterolemia. 120 subjects are planned to be enrolled. Each subject is required a maximum of 6 weeks of screening, 24 weeks of treatment, and 8 weeks of follow-up. To evaluate the lipid-lowering efficacy of subcutaneous injection of JS002 at 24 weeks compared with placebo in heterozygous familial hypercholesterolemia patients under optimized lipid lowing therapy . Subjects meeting the study inclusion criteria will be randomly assigned in a 2:1:2:1 ratio to JS002 150 mg Q2W or JS002 450 mg Q4W or matched placebo to receive the study drug (JS002) or placebo subcutaneously for 24 weeks. treatment cohorts: JS002 150mg Cohort:JS002 150mg or placebo treatment(JS002 :Placebo=2:1) Q2W JS002 450mg Cohort:JS002 450mg or placebo treatment(JS002 :Placebo=2:1)Q4W
